Installing or Replacing Components

This chapter describes the replacement and other maintenance procedures for the Cisco Nexus 7000 Series switch components. You can also use these procedures for installing modules and other features purchased after you receive the switch.

A Cisco Nexus 7000 Series switch is designed for redundancy, which means that you can replace its modules, fan trays, and power supply units if there is at least one other of the same type operating during the replacement process.

This chapter includes the following sections:

Replacing an AC Power Supply Unit During Operations

The Cisco Nexus 7000 Series switches use a load-balanced power supply that uses up to four AC, DC or HVAC/HVDC power supply units. The AC power supply units convert up to 1.2 kW, 1.4 kW, 3 kW, 3.5 kW, 6 kW, or 7.5 kW of AC power to DC power for system operations. If you can set one power supply unit in standby mode and have the required power load balanced by the remaining online power supply units, you can replace the standby power supply unit with another power supply unit without interrupting system operations.

Replacing a Supervisor Module

The Cisco Nexus 7000 Series switches can be configured with one or two supervisor modules. If the system has two supervisor modules, you can replace one of the supervisors while the other one manages system operations. If the system has only one supervisor, you must bring the system down to replace the supervisor module because the supervisor module is required for managing operations.

note.gif

Noteblank.gif If you need to bring down the switch to change supervisors, you must also copy the running configuration, system messages, VDC configurations, and licenses onto a USB drive before removing the supervisor module as explained in the “Replacing a Supervisor Module” section.


caut.gif

Caution blank.gif Make sure that you do not accidentally press one or more of the ejector release buttons on the I/O, supervisor, and fabric modules. These buttons and their mechanical levers are designed so that you can easily power down and remove these modules when you need to replace them. If you press one of these buttons, the lever for that button releases from the front of the module, but the module remains operational and connected to the system. If you press the other ejector button on the same module at the same time as you press the first button or while the lever for the first button is released, the lever for the second button releases, and the module powers down and disconnects from the system.

To minimize the chance of accidentally disconnecting a module with a released lever, press the lever back toward the module until it clicks. If both levers are released, the system has disconnected and powered down the module, and the STATUS LED will be unlit. To reconnect and power up the module, either remove and reinsert the module in the chassis or use system commands to power it on.

You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on the supervisor module.

Replacing a Redundant Supervisor Module During System Operations

During operations, one supervisor is active while the other (redundant) supervisor is in standby mode. You can replace either of these two supervisors. If you need to replace the active supervisor, it becomes the standby supervisor as soon as you press its ejector buttons.

note.gif

Noteblank.gif A replacement supervisor module comes with one DIMM (4 GB of memory) or, if your switch is running Cisco NX-OS 5.1 (or later release), two DIMMs (8 GB of memory). If the switch not running a version of Cisco NX-OS that is compatible with using 8 GB of memory, then you must use only one DIMM (do not install an additional DIMM).


caut.gif

Caution blank.gif If you cannot immediately replace a supervisor, either leave the supervisor in its slot until it can be replaced or replace it with a blank module so the system airflow is not disrupted. If the system airflow is disrupted for more than a couple of minutes, the system could overheat and shut down.

Unscrew two captive screws.

3

Simultaneously swing open both ejector levers to unseat the module.

2

Simultaneously press both ejector buttons.

 

 

Step 4blank.gif Press the ejector release buttons on the ends of the module (see View B of Figure 10-5) to push out the ejector levers and to disconnect the module.

If the chassis has two supervisor modules and you disconnect the active supervisor module, that supervisor goes into standby mode and the other supervisor automatically becomes the active supervisor.

Step 5blank.gif Disconnect the cables attached to the front of the module to be removed. Make sure that each cable is labelled for its port on the module.

Step 6blank.gif Simultaneously rotate the two ejector levers outward to unseat the module from the midplane connector (see View C of Figure 10-5).

Step 7blank.gif With a hand on each ejector, pull the module part way out of its slot in the chassis.

Step 8blank.gif Grasp the front edge of the module with your left hand and place your right hand under the lower side of the module to support its weight. Pull the module out of its slot.

caut.gif

Caution blank.gif To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming in contact with the circuitry.

Step 9blank.gif If you are removing the module from a Cisco Nexus 7010 chassis, rotate the module 90 degrees counterclockwise so that it is horizontal and you can see its circuitry from above.

Step 10blank.gif Place the removed module in an antistatic bag.

Step 11blank.gif Repack the bagged I/O module in its original packing materials as shown in Figure 10-6.

Figure 10-6 Repacking a Supervisor Module

1

Put the module in an ESD bag.

7

Tape the flap to the box.

2

Place the bagged module on the foam pad.

8

Insert the two box sides into foam blocks.

3

Attach a side pad to each of the long sides of the module.

9

Place the box and its foam blocks into the larger box.

4

Fold the side flaps up along the side pads.

10

Fold the narrow flaps over the smaller box and foam blocks.

5

Fold the long flaps up along the ends of the module and then over the top of the module. Insert the two tabs on each flap into the side flaps.

11

Fold the wide flaps over the box.

6

Insert the folded box into the slightly larger box.

12

Tape the wide flaps together and to the box.

Step 12blank.gif On the replacement module, rotate both of the ejector levers away from the front of the module.

Step 13blank.gif If you are inserting the module into a Cisco Nexus 7010 chassis, rotate the module 90 degrees clockwise.

Step 14blank.gif Align the module to the chassis guides for the vacated slot (slot 5 or 6 on the Cisco Nexus 7010 chassis or slot 9 or 10 on the Cisco Nexus 7018 chassis), and slide the module part way into the slot.

Step 15blank.gif With one or both hands on the front of the module, push the module all the way into the slot until it seats on the midplane connector.

Step 16blank.gif Simultaneously push both ejector levers inward until they come in contact with the face of the module.

The module should be fully seated in the slot and the captive screws should be aligned with their holes in the chassis. The EMI gasket should close the gap between the new module and the module in the next slot to the right.

Step 17blank.gif Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).

Step 18blank.gif Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the “Connecting to the Console” section.

Step 19blank.gif If the previous supervisor module was connected to an asynchronous device through a modem, connect the modem cable to the COM1/AUX SERIAL PORT as explained in the “Connecting to the Console” section.

Step 20blank.gif Reconnect the network management cable to the MGMT ETH port as explained in “Setting Up the Management Interface” section.

Step 21blank.gif Reconnect the CMP cable to the CMP MGMT ETH port as explained in “Connecting the Supervisor CMP Port” section.

Step 22blank.gif Copy the license file from the active supervisor to the standby supervisor. Use the copy bootflash:license-filename.lic bootflash://supervisor-standby/license-filename.lic.lic command to copy the license file.

Step 23blank.gif Verify that both supervisors have the same amount of memory by following these steps:

a.blank.gif Use the show system resources command to see how much memory is installed in the active supervisor.

b.blank.gif Use the system switchover command to make the other supervisor module active.

c.blank.gif Use the show system resources command to see how much memory is installed in the other supervisor.

If one of the supervisor modules has more memory than the other supervisor module, you must either remove 4 GB from the module with 8 GB (see the “Removing 4 GB of Memory from a Supervisor Module” section) or add 4 GB to the module with 4 GB (see the“Adding 4 GB of Memory to a Supervisor Module” section).


 

Replacing a Supervisor Module in a Single-Supervisor System

If you need to replace the supervisor in a single-supervisor Cisco Nexus 7000 Series system, you must shut down the system before replacing the supervisor.

note.gif

Noteblank.gif A replacement supervisor module comes with one DIMM (4 GB of memory) or, if your switch is running Cisco NX-OS 5.1 (or later release), two DIMMs (8 GB of memory). If the switch not running a version of Cisco NX-OS that is compatible with using 8 GB of memory, you must use only one DIMM (do not install an additional DIMM).

Replacing Supervisor 1 Modules with Supervisor 2 or Supervisor 2E Modules

Before migrating from Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules, note the following guidelines:

  • This migration process is disruptive for switches with one or two supervisor modules because the power must be turned off for the switch.
  • Backward migration procedure (migrating from Supervisor 2 or Supervisor 2E modules to Supervisor 1 modules) is not provided.
  • We recommend that you use Cisco NX-OS Release 5.2 (or later release) on the Supervisor 1 module while performing the migration.
  • You cannot mix Supervisor 2 and Supervisor 2E modules in a production environment (this mix of modules is supported only while you are migrating from using Supervisor 2 modules to Supervisor 2E modules as explained in the “Replacing Supervisor 2 Modules with Supervisor 2E Modules” section). You must replace redundant Supervisor 1 modules with either two Supervisor 2 modules or two Supervisor 2E modules.
  • If you plan to enable the admin VDC feature on the Supervisor 2 or Supervisor 2E modules, be sure to complete the entire migration procedure before enabling this feature (see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide).
  • The default-gateway command needs to be removed and replaced with ip route under the cmp-mgmt interface when SUP1 is upgraded to SUP-2/SUP-2E.
  • If you are migrating Supervisor 1 Modules with Supervisor 2 or Supervisor 2E Modules, then replace ip default-gateway x.x.x.x' with ip route 0/0 x.x.x.x in the config.

To migrate from using Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules, follow these steps:


Step 1blank.gif Insert a USB drive in the top USB port (usb1) in the active supervisor 1 module. If the Supervisor 2 or Supervisor 2E module shipped with an extra USB drive, you can insert that USB drive in the usb1 drive on the Supervisor 1 module.

note.gif

Noteblank.gif Do not use the USB drive that is in the LOG FLASH port.


Step 2blank.gif Format the drive by using the format command.

switch(config)# format usb1:

Step 3blank.gif Copy all of the VDC configurations for the switch to the USB drive by using the copy running-config command.

switch(config)# copy running-config usb1:configuration_file_name vdc-all

Step 4blank.gif Backup the installed licenses for the switch to the USB drive by using the copy licenses command.

switch(config)# copy licenses usb1:licenses_archive_file_name.tar
note.gif

Noteblank.gif You must use the tar extension for the archive file. This file will contain all of the license files that were installed on the Supervisor 1 module.


Step 5blank.gif Determine the Cisco NX-OS software release to use on the Supervisor 2 or Supervisor 2E modules. We support Cisco NX-OS Release 6.1(1) (or later release) on those modules but another one might be recommended. Additionally, the most recommended maintenance release might not be the one that ships with the Supervisor 2 or Supervisor 2E modules. We recommend that you check with the following documents for the recommended software release:

  • Minimum Recommended Cisco NX-OS Releases for Cisco Nexus 7000 Series Switches
  • Cisco Nexus 7000 Series NX-OS Release Notes, Release 6.1

Step 6blank.gif Copy the Supervisor 2 or Supervisor 2E version of the kickstart, system, and EPLD (optional) images to the USB drive by using the copy command.

switch(config)# copy scp://path/n7000-s2-kickstart.6.1.1.bin usb1:
switch(config)# copy scp://path/n7000-s2-dk9.6.1.1.bin usb1:
switch(config)# copy scp://path/n7000-s2-epld.6.1.1.img usb1:
note.gif

Noteblank.gif This example specifies the NX-OS Release 6.1(1) images. For a later release, use the later release number in the.bin or.img file name.


caut.gif

Caution blank.gif Use -s2- images with Supervisor 2 or Supervisor 2E modules. If you use an -s1- image with a Supervisor 2 or Supervisor 2E module, the supervisor will not boot up.

note.gif

Noteblank.gif Although the Supervisor 2 and Supervisor 2E ship with updated EPLD images, you might need to update the EPLD images on the other modules on the switch. For example, migrating from Supervisor 1 modules to Supervisor 2 or Supervisor 2E modules on switches that use Fabric 2 modules requires EPLD updates for the fabric modules. For more information, see the Cisco Nexus 7000 Series FPGA/EPLD Upgrade Release Notes, Release 6.1 or later release.


Step 7blank.gif Turn off the power to the switch by turning the power switch on each power supply from ON to STBY (Standby). The Output LED turns off on each power supply and the Status LEDs turn off on all of the supervisor and I/O modules.

caut.gif

Caution blank.gif If any of the supervisor or I/O module Status LEDs is turned on (showing any color), stop at this step until you are able to turn off those modules.

Step 8blank.gif For each Supervisor 1 module installed in the switch, remove the module and replace it with a Supervisor 2 or Supervisor 2E module as explained one of the following sections:

caut.gif

Caution blank.gif If the switch has two supervisor modules, be sure that both supervisors are the same type. Do not mix Supervisor 1 modules with Supervisor 2 or Supervisor 2E modules and do not mix Supervisor 2 modules with Supervisor 2E modules.

Step 9blank.gif Power up the switch by turning the power switch on each of its power supplies from STBY (standby) to ON. The Output LED on each power supply turns on and eventually turns green when the power supply is sending power to the switch. The Status LED on each installed supervisor module also turns on when the module begins to turn on. The supervisor that becomes active has a green ACTIVE LED (the standby supervisor module has an amber ACTIVE LED).

Step 10blank.gif Remove the USB drive from the Supervisor 1 module (this drive has copies of the Supervisor 1 configuration, license, and software images) and insert it in the Slot0: USB port on the active Supervisor 2 or Supervisor 2E module (ACTIVE LED is green).

Step 11blank.gif Connect a console to the active supervisor module as explained in “Connecting to the Console” section.

Step 12blank.gif If you are setting up the initial configuration for the supervisor module, the initial setup script will ask you if you want to enforce the secure password standard. Make your selection, enter your password, and then confirm the password by entering it again.

Step 16blank.gif Verify that the switch is running the required version of the NX-OS software by using the show version command.

switch(config)# show version
note.gif

Noteblank.gif If the version of NX-OS is not the same as you intended to use, copy the previously saved images from the USB drive in SLOT 0 to bootflash: and perform an upgrade to the appropriate version. For more information, see the Cisco Nexus 7000 Series NX-OS Software Upgrade and Downgrade Guide.


Step 17blank.gif Copy the TAR archive containing the license files from the USB SLOT 0 drive to bootflash:, extract the archive, and install the licenses by using the copy, tar extract, and install license commands. Repeat the install license command for each extracted license file.

switch(config)# copy slot0:licenses_archive_file_name.tar bootflash:
switch(config)# tar extract bootflash:licenses_archive_file_name.tar to bootflash:
switch(config)# install license bootflash:license_file_name.lic
note.gif

Noteblank.gif The tar extract command requires that the TAR file be located in bootflash: or volatile:.


Step 18blank.gif Make sure that all I/O modules are online and that the standby supervisor is in ha-standby mode by using the show module command.

switch(config)# show module
Mod Ports Module-Type Model Status
--- ----- ----------------------------------- ------------------ ---------------
2 0 Supervisor module-2 N7K-SUP2E active *
6 0 Supervisor module-2 N7K-SUP2E ha-standby
7 48 1/10 Gbps Ethernet Module N7K-F248XP-25 ok
...
 

Step 19blank.gif If there are Fabric 2 modules in the switch, upgrade the Fabric 2 EPLDs (see the “Configuring EPLDs” section).

Step 20blank.gif Restore the previously saved configurations by using the copy command to copy the configuration file in the USB drive to the running configuration.

switch(config)# copy slot0:configuration_file_name running-config
note.gif

Noteblank.gif While the configuration is applied on the Supervisor 2 or Supervisor 2E module you will see an error that indicates a problem with the cmp-mgmt interface or AUX port. The Supervisor 2 and Supervisor 2E modules do not have the CMP utility nor the AUX port, so you can disregard this error message.

switch(config)# interface cmp-mgmt module 5
^
Invalid interface format at ‘^’ marker.
...
switch(config)# line com1
^
% Invalid command at ‘^’ marker.


note.gif

Noteblank.gif If the imported configuration file includes configurations for Fabric Extenders (FEXs) and those modules are not up yet, you will see error messages for that. If that happens, we recommend that you run the FEX configuration again after the FEX modules come online. You can verify the status of the FEX modules and for the associated server-facing interfaces by using the show fex and show interface brief commands.


note.gif

Noteblank.gif If you have not inserted the standby supervisor module until now, do not insert it during this step. Instead, wait until you complete this procedure before installing the standby supervisor module.


note.gif

Noteblank.gif When upgrading from Supervisor 1 to Supervisor 2, any configuration that is a part of the CMP module may be erroneously applied to the interface above it.


Step 21blank.gif Save the configuration in the startup configuration by using the copy running-config startup-config vdc-all command.

switch(config)# copy running-config startup-config vdc-all


 

Replacing Supervisor 2 Modules with Supervisor 2E Modules

Before migrating from Supervisor 2 modules to Supervisor 2E modules, note that non disruptive backward migration (migrating from Supervisor 2E modules to Supervisor 2 modules during switch operations) is not supported—in a switch with two supervisor modules and an active Supervisor 2E module, a Supervisor 2 will not boot up nor synchronize with the active Supervisor 2E module.

To migrate from using Supervisor 2 modules to Supervisor 2E modules, follow these steps:


Step 1blank.gif Replace one of the Supervisor 2 modules by following the steps in the “Replacing a Redundant Supervisor Module During System Operations” section.

Step 2blank.gif Verify that the Supervisor 2E module has 2 CPUs and 32 GB of DRAM by looking at the bootup output (see the highlighted portions in the following example).

CPU - 2 : Cores - 4 : HTEn - 1 : HT - 2 : Features - 0xbfebfbff
FSB Clk - 532 Mhz : Freq - 2144 Mhz - 2128 Mh
MicroCode Version : 0xffff0002
Memory - 32768 MB : Frequency - 1067 MHZ
 

Step 3blank.gif Monitor the console output for the active Supervisor 2. When the standby Supervisor 2E fully boots up, note that the console displays a SYSLOG message similar to the following:

2012 Jul 26 14:28:23 switch %SYSMGR-2-CTIVE_LOWER_MEM_THAN_STANDBY: Active Supervisor in slot 1 is running with less memory than standby supervisor in slot 2.

This message states that the Supervisor 2E module has more memory than the Supervisor 2 module (as expected).

Step 4blank.gif Verify that both supervisor modules have synchronized their states by using the show mod and show system redundancy ha status commands.

switch# show mod
Mod Ports Module-Type Model Status
--- ----- ----------------------- -------------- ---------
1 0 Supervisor module-2 N7K-SUP2 active
2 0 Supervisor module-2 N7K-SUP2E ha-standby
 
switch# show system redundancy ha status
VDC No This supervisor Other supervisor
------ --------------- ----------------
vdc 1 Active with HA standby HA standby
vdc 2 Active with HA standby HA standby
vdc 3 Active with HA standby HA standby
vdc 4 Active with HA standby HA standby
 

Step 5blank.gif Make the Supervisor 2E module active by using the system switchover command.

switch# system switchover

When the Supervisor 2E becomes active, the Supervisor 2 powers down and will not come up as a standby supervisor.

2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %SYSMGR-2-SUP_POWERDOWN; Supervisor in slot 1 is running with less memory than active supervisor in slot 2
2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %SYSMGR-2-CONVERT_STARTUP_ABORTED: Conversion of startup-config failed.
2012 Jul 26 14:50:19 switch %$ VDC-1 %$ %PLATFORM-2-MOD_PWRDN: Module 1 powered down
 

Step 6blank.gif Verify that the Supervisor 2E module is active and that the Supervisor 2 is powered down by using the show module command.

switch# show mod
Mod Ports Module-Type Model Status
--- ----- ----------------------- -------------- ---------
1 0 Supervisor module-2 N7K-SUP2 powered-dn
2 0 Supervisor module-2 N7K-SUP2E active *
...
 
Mod Power-Status Reason
--- ------------ ----------------------------
1 powered-dn Policy trigger initiated reset: Stdby has lower mem than active
 

Step 7blank.gif Remove the Supervisor 2 module, which is powered down (LEDs are off).

note.gif

Noteblank.gif If you intend to use a single Supervisor 2e module, the procedure is complete. If you intend to use redundant Supervisor 2e modules, continue with the following steps.


Step 8blank.gif Install a Supervisor 2E module in the open slot and connect it to the console (see the “Replacing a Redundant Supervisor Module During System Operations” section).

Step 9blank.gif Verify that both supervisor modules have synchronized their states by using the show mod and show system redundancy ha status commands.

switch# show mod
Mod Ports Module-Type Model Status
--- ----- ----------------------- -------------- ---------
1 0 Supervisor module-2 N7K-SUP2E active
2 0 Supervisor module-2 N7K-SUP2E ha-standby
 
switch# show system redundancy ha status
VDC No This supervisor Other supervisor
------ --------------- ----------------
vdc 1 Active with HA standby HA standby
vdc 2 Active with HA standby HA standby
vdc 3 Active with HA standby HA standby
vdc 4 Active with HA standby HA standby


 

Upgrading Memory for Supervisor 1 Modules

The Cisco Nexus 7000 Series Supervisor 1 modules use either 4 GB or 8 GB of memory. For switches that have two supervisor modules, each module must have the same amount of memory so that it can provide redundant services for the other. In order to use 8 GB of memory, a switch must be running Cisco NX-OS Release 5.1 or later release. If the switch is running an earlier release of Cisco NX-OS, the supervisor modules must have only 4 GB of memory installed.

note.gif

Noteblank.gif The Cisco NX-OS software may require 8 GB of memory, depending on the software version you use and the software features that you enable. If your switch has Supervisor 1 modules with only 4 GB of memory, then you might need to upgrade the modules to 8 GB of memory by using the 8 GB supervisor upgrade kit (N7K-SUP1-8GBUPG=). This upgrade is not needed for switches that have at least 8 GB of memory (which includes Supervisor 1 modules with 8 GB and all Supervisor 2 and Supervisor 2E modules).


To determine the amount of memory installed in the active supervisor, use the show system resources command as shown in Example 10-1. To determine the amount of memory used by the standby supervisor module, use the system switchover command to make that module active and then use the show system resources command. This example shows the output for the show system resources command, which shows 4115768K (4 GB) of memory usage.

Example 10-1 Determining the Amount of Memory used by the active supervisor module.

switch# show system resources
Load average: 1 minute: 0.22 5 minutes: 0.25 15 minutes:0.15
Processes : 860 total, 3 running
CPU states : 0.0% user, 6.5% kernel, 93.5% idle
Memory usage: 4115768K total, 2747512K used, 1368256K free
 
switch#
 

The following guidelines can help you determine whether or not to upgrade an existing Supervisor 1 module:

  • When the switch memory usage exceeds 3 GB (75 percent of total memory), we recommend that you upgrade the memory to 8 GB.
  • If you create more than one VDC with XL mode enabled, or if you have more than two VDCs, 8 GB is required.

For additional guidance about whether or not to upgrade a supervisor module to 8 GB of memory, see Figure 10-8.

Figure 10-8 Supervisor Memory Upgrade Decision Flowchart

To determine which version of Cisco NX-OS that the switch is running, use the show version command.

This section includes the following topics:

Adding 4 GB of Memory to a Supervisor Module

If you need to add 4 GB of memory to the supervisor modules on your switch so that they have 8 GB of memory, the switch must be running NX-OS Release 5.1(1) or later release.

note.gif

Noteblank.gif If the switch has two supervisor modules, both must have the same amount of memory. If you upgrade the standby supervisor module to 8 GB of memory, you must then switch the active supervisor to standby and upgrade the new standby supervisor to 8 GB of memory.

Noteblank.gif If you are using an earlier version of Cisco NX-OS, the supervisor modules can have only 4 GB of memory. If you need to remove 4 GB of memory to have only 4 GB of memory in a supervisor, see the “Removing 4 GB of Memory from a Supervisor Module” section.


To add 4 GB of memory to the supervisor modules, follow these steps:


Step 1blank.gif Follow ESD procedures, which include wearing an ESD wrist strap and placing antistatic foam or antistatic padding where you will place the supervisor module while working with it.

Step 2blank.gif Disconnect the cables attached to the front of the module to be removed. If there are two supervisors in the switch, disconnect the cables from the standby supervisor.

note.gif

Noteblank.gif If the chassis has two supervisor modules and you disconnect the active supervisor module, that supervisor goes into standby mode and the other supervisor becomes the active supervisor.


Step 3blank.gif Loosen and fully unscrew both captive screws on the module.

Step 4blank.gif Press both ejector release buttons on the ends of the module (see Callout 2 in Figure 10-5) to push out the ejector levers and to disconnect the module.

note.gif

Noteblank.gif If you stop this procedure at this point without removing the module and need to power it up, simultaneously press both ejector levers back to the face of the module until they click, secure both of the module captive screws to the chassis, and then use the no poweroff module slot_number command to power up the module.


Step 5blank.gif Simultaneously rotate the two ejector levers outward to unseat the module from the midplane connector (see Callout 3 in Figure 10-5).

Step 6blank.gif With a hand on each ejector lever, pull the module part way out of its slot in the chassis.

Step 7blank.gif Grasp the front edge of the module with one hand and place your other hand under the lower side of the module to support its weight. Pull the module out of its slot.

Installing an I/O Module

A Cisco Nexus 7004 switch has up to two I/O modules, a Cisco Nexus 7009 switch has up to seven I/O modules, a Cisco Nexus 7010 switch has up to eight I/O modules, and a Cisco Nexus 7018 has up to 16 I/O modules. These modules are located on the front of the chassis. You can replace one of these modules at a time while the switch is operating.

note.gif

Noteblank.gif If you are installing F2 I/O modules, all of the fabric modules in the switch must be Series 2 fabric modules.


This section describes how to replace I/O modules and includes the following topics:

Required Tools

You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on the I/O module.

Installing a New I/O Module

A Cisco Nexus 7000 Series switch includes one or more of the following types of I/O modules:

  • 48-port 10/100/1000 Ethernet module (N7K-M148GT-11)
  • 48-port 10/100/1000 Ethernet module with XL option (N7K-M148GT-11L)
  • 48-port 1-Gigabit Ethernet I/O module (N7K-M148GS-11)
  • 48-port 1-Gigabit Ethernet I/O module with XL option (N7K-M148GS-11L)
  • 48-port 1-/10-Gigabit Ethernet I/O modules with XL (N7K-F248XP-25 and N7K-F248XP-25E)
  • 48-port 1-/10-Gigabit Ethernet I/O module (N7K-F348XP-25)
  • 48-port 1-/10-Gigabit Ethernet I/O modules with XL option(N7K-M348XP-25L)
  • 24-port 10-Gigabit Ethernet I/O modules with XL option (N7K-M224XP-23L)
  • 24-port 40-Gigabit Ethernet I/O modules with XL option(N7K-M324FQ-25L)
  • 32-port 10-Gigabit Ethernet I/O module (N7K-M132XP-12)
  • 32-port 10-Gigabit Ethernet I/O module with XL option (N7K-M132XP-12L)
  • 32-port 1- and 10-Gigabit Ethernet I/O module (N7K-F132XP-15)
  • 8-port 10-Gigabit Ethernet I/O module with XL option (N7K-M108X2-12L)
  • 12-port 40-Gigabit Ethernet I/O module (N7K-F312FQ-25)
  • 6-port 100-Gigabit Ethernet I/O module (N7K-F306CK-25)

You can replace each of these I/O modules with another module of the same type while the Cisco Nexus 7000 Series switch is operational. To do this action, you must first remove an I/O module from the chassis, and then install a new or replacement I/O module in the newly vacated slot within a couple of minutes to maintain the designed airflow.

note.gif

Noteblank.gif M3-Series I/O modules are not supported on the Cisco Nexus 7004 switch.


note.gif

Noteblank.gif On a Cisco Nexus 7000 Series switch, when a transceiver is removed or inserted on an interface in a VDC (for example VDC-1), a trap is sent to all the VDCs in the switch (including the VDC-1). This behavior is applicable for module removal or insertion and to other physical entity events.

Installing a NAM Module

The Network Analysis Module (NAM) can be installed in an I/O module slot on the Cisco Nexus 7004, 7009, 7010, or 7018 switch chassis. You can either replace a NAM or install a new one in an empty I/O module slot. If you install a new module, you must also install and configure the latest NAM software on the module.

note.gif

Noteblank.gif If the switch shipped with one or more NAM modules already installed, then the modules are already configured with the Prime NAM software and are ready to be used. If you are installing a new NAM module and the module does not automatically boot up, then you must install and configure the Prime NAM software in order to use the module.


This section describes how to install NAM modules and includes the following topics:

Required Tools for Installing a NAM

Installing or Replacing a NAM

A Cisco Nexus 7004, 7009, 7010, or 7018 switch can have one or more NAMs installed in it. You can either install a new one in an empty I/O module slot or replace an existing NAM or I/O module. If you are replacing an existing NAM, you must first shut down the module with the out-of-service module command before removing the original module. If you are replacing an I/O module, you can either use the out-of-service module command to shut the module down or just remove the module and a graceful shutdown will automatically occur.

Step 3blank.gif Click the Download button for the software file name beginning with nam-nx1. The filename is nam-nx1. x-x-x.bin.gz (where x-x-x is the NAM software release number).

Step 4blank.gif Using the NAM CLI, enter the upgrade command to specify the user, password, server,path to the file, and installation file name. For example, for the admin user, “secret” password, server IP address 10.10.10.10, archive/nam_software path, and nam-nx1.6.0.1.bin.gz installation file, you would use the upgrade command as follows:

upgrade ftp://admin:secret!10.10.10.10//archive/nam_software/nam-nx1.6.0.1.bin.gz


 

Configuring the NAM

To configure the NAM software, you must do all of the following:

Configuring a VLAN Management Port for the NAM

Using the virtual device context (VDC) that the NAM belongs to, you must configure a VLAN for NAM management traffic, and you must assign that VLAN to the NAM management port.

To configure and assign a VLAN management port, follow these steps:


Step 1blank.gif Verify that the NAM is active.

switch# show service nam summary
Service Service
Name Type Interface Module State Version
---------------- ----------- -------------- --------- --------- ---------------
NAM7 NAM Po4096, Po4095 7 active 6.0

Step 2blank.gif Allocate the NAM interfaces to the VDC as follows:

  • If you are using the default VDC configuration, the NAM interfaces should be allocated to the default VDC automatically. Verify that allocation.

After you have configured a VLAN management port for the NAM, you need to set up a SPAN session to define the switch as the traffic source and the NAM as the traffic destination. You can set up a SPAN session in either one of following ways:

Configuring a SPAN Session for a Data Port

To use the NAM with a switch, you must define a SPAN session between the switch and the NAM. You can specify the switch by its interface and specify the NAM by its data port.

If you need to define the NAM by the port channel used, see the “Configuring a SPAN Session for a Port Channel” section.

Replacing Storage Media for a Supervisor Module

You can replace a CompactFlash card in either flash memory reader on any Supervisor 1 module or a USB drive in either USB port on any Supervisor 2 or Supervisor 2E module. The replacement media must already be formatted for the reader or port, or you must reformat the media after installing it.

note.gif

Noteblank.gif The LOG FLASH and EXPANSION FLASH readers (Supervisor 1) and the LOG FLASH and SLOT0 ports (Supervisor 2 or 2E) require different formats for their cards.


To replace storage media on a supervisor module, follow these steps:


Step 1blank.gif Press the Eject Request button for the reader or port that has the media to be replaced.

Step 2blank.gif Wait for the reader or port LED to turn off and to see an offline message for that reader or port.

Step 3blank.gif Remove the card from the reader.

Step 4blank.gif Insert the replacement media as follows:

  • For the Supervisor 1 modules, align the replacement card to the CompactFlash reader slot as shown in Figure 4-10 and push the card all the way into the slot. The grooves on the thin side of the card must begin on the end of the card that goes into the reader first. If the card does not fit easily into the slot, flip the card so the bottom edge is on top, and try pushing the card into the slot.
  • For the Supervisor 2 or Supervisor 2E modules, insert the replacement USB drive in the USB port.

Step 5blank.gif Wait for the reader LED to turn green and for an online message to appear on the console.

note.gif

Noteblank.gif If you see an offline message or do not see a message, either the card is not fully pushed into the reader or it is improperly formatted. If the card is fully inserted, either format the card (see the Cisco NX-OS Fundamentals Configuration Guide) or replace the card with another card that is properly formatted for the reader.

Step 11blank.gif Fasten the captive screws on the air intake frame to the chassis and tighten to 11 to 15 in-lb (95 to 130 N·m).

Step 12blank.gif On the chassis door, pull the door handle open on one of the two sides of the door until the handle clicks (the handle clicks when you pull it out about 30 degrees).

Step 13blank.gif Move the side of the door with the opened handle onto the two hinge pins as shown in Figure 10-49. Make sure that the hinge pins on the top cover and bottom hinge bracket fit through the slots on the top and bottom of that side of the door. Position the door so the hinge pins are located at the ends of the slots.

Noteblank.gif Be sure that the door is firmly latched to the two hinge pins. If both of the hinge pins are not secured behind the door latch, hold the door securely with one hand while opening the door handle for the unsecured side until the handle clicks, press that side of the door so that both of the pins are positioned all the way inside the door slots, press the door latch button on the interior side of the door, and then make sure that the door is firmly secured to both hinge pins.


Step 15blank.gif Open the door handle on the open side of the door until it clicks. This action opens the latches on the open side of the door. See Figure 10-51.

Slots for hinge pins.

Step 16blank.gif Swing the door closed so that the remaining two pins on the bottom hinge bracket and top cover fit inside the slots on the top and bottom of the door. When you close the door, the door stopper automatically presses the lock button on the inside of the door so that the door is locked on the hinge pins. If the door stopper does not close the latches, press the door closed at the handle until you hear the latches click. Make sure that the door is fully secured to the frames on both sides.

Noteblank.gif If a hinge pin is not secured behind a door latch, open the door handle for that side of the door until it clicks, open that side of the door, and then press the door closed so that the pins are positioned all the way inside the door slots. When you close the door, the door stopper automatically closes the door latches. If you do not hear the latches click, press the door at the handle to fully close it and to activate the latches. Test the door to make sure that it is fully secured to the four hinge pins.

Tipblank.gif Whenever you need to open the door, pull one of the latch handles open until it clicks and then swing that side of the door open.


note.gif

Noteblank.gif If the double-hinged door and its holders are not level, it is possible that you will have some difficulty opening or closing the door on one or both sides without the door being defective. Either push in the bottom portion of the door or slightly lift up the door on that side just before closing. If the problem persists, open the door from the other side, which should be free of this problem, or adjust the cable management system and hinge bracket so that they are level.

To replace the air filter, follow these steps:


Step 1blank.gif On the right side of the chassis, remove eight screws that hold the airfilter to the chassis.

Step 2blank.gif Remove the air filter.

Step 3blank.gif Place the new air filter over the air intake area on the right side of the chassis and align the eight screw holes in the filter to screw holes in the chassis.

Step 4blank.gif Fasten the air filter to the chassis using eight M3 x 5 mm screws that came with the air filter.. Tighten the screws to 5 to 7 in-lb (0.56 to 0.79 N.m).


 

Cleaning or Replacing the Air Filter for the Cisco Nexus 7010 Chassis

You can clean or replace the optional air filter while the Cisco Nexus 7010 system is operational.

note.gif

Noteblank.gif We recommend that you check the air filter once a month. If it is covered with an oily substance, you should replace it. If it is covered with dust, you can clean it and continue to use it.


To clean or replace the air filter, follow these steps:


Step 1blank.gif On the left and right side of the existing air filter, loosen the two captive screws so they are no longer attached to the chassis. The air filter can be found covering the air intake area at the bottom of the front side of the chassis (see Figure 1-5).

Step 2blank.gif With one hand holding the air filter in place, use the other hand to pull out the spring pin on one side of the air filter. Pull that side of the air filter away from the chassis and release the spring pin when it is clear of the bracket on the EMI frame.

Step 3blank.gif Switch the hands holding the air filter and use the other hand to pull out the spring pin on the other side of the air filter. Pull the air filter away from the chassis and release the spring pin.

Step 4blank.gif If the filter is covered with an oily substance, we recommend that you replace it. If the filter is dusty, you can take it outside the data center and clean it in one or more of the following ways:

  • Use a vacuum cleaner over both sides of the filter.
  • Blow compressed air through the exhaust side of the filter.
  • Rinse the filter with cold water.
  • Immerse the filter in warm, soapy water, and then rinse it.

Noteblank.gif If the filter gets wet while you clean it, make sure that it dries before you reinstall it.


Step 5blank.gif Align the cleaned or replacement air filter to the EMI frame covering the air intake area.

Step 6blank.gif Use one hand on the air filter to hold it in place while you use the other hand to pull out the spring pin on one side of the air filter. Adjust the air filter so that the spring pin will be released into its hole in the EMI frame bracket.

Step 7blank.gif Switch the hands holding the air filter and use the other hand to pull out the other spring pin on the other side of the air filter. With the spring pin pulled out, position the air filter so that the pin will be released into its hole on the EMI frame bracket. Release the spring pin and make sure that it holds the air filter on to the EMI frame.

Step 8blank.gif Screw in and tighten both captive screws, one on each side of the air filter.
