To disconnect fiber optic cables from the QSFP28 ports, we recommend that you first remove the QSFP28 transceiver module from the port, then remove the cable.

Online Insertion and Removal


Note
Installing an MPA in the Cisco ASR 9001 router will cause brief traffic interruption on the fixed ports due to the network processor (NP) initializing.

The Modular Port Adapters (MPAs) on Cisco ASR 9001 router support online insertion and removal (OIR).

Cisco ASR 9903 800G Multirate Port Expansion Card supports online insertion and removal (OIR).

Modular port adapters (MPAs) support three types of OIR(s):

  • Soft OIR

  • Managed OIR

  • Hard OIR

The 2T or 0.8T Port Expansion Cards (PECs) on the Cisco ASR 9903 chassis support managed OIR.

For more information on how to install or remove a PEC, see Install the Port Expansion Card or Remove the Port Expansion Card. To replace a PEC with another PEC, use the managed OIR procedure.

Limitation:

  • During online insertion and removal of MPA on the Cisco ASR 9001 router, the field-programmable gate array (FPGA) turns off and the physical interface (PHY) is unavailable to inhibit the clock. As a result, you will observe a SyncE jump of 80 - 120 ns on downstream nodes.

Soft OIR

Soft OIR uses the IOS XR hw-module subslot 0/0/1 reload , hw-module subslot 0/0/1 shutdown , and no hw-module subslot 0/0/1 shutdown commands to complete online insertion and removal. Refer to the Hardware Redundancy and Node Administration Commands on the Cisco ASR 9000 Series Router chapter of the Cisco ASR 9000 Series Aggregation Services Router System Management Command Reference online for command syntax.

Managed OIR

A managed online insertion and removal of Modular port adapters (MPAs) or Port Expansion Card (PEC) is comprised of these steps:

  1. Shut down the MPA or PEC with the hw-module subslot 0/0/1 shutdown command.

  2. Confirm that the LEDs have gone from green to off.

  3. Execute the do show plat command to verify that the MPA or PEC to be removed is in the disabled state.

  4. Physically remove the MPA or PEC to be replaced.

  5. Physically insert the replacement MPA or PEC.

  6. Return the MPA or PEC to the up state with the no hw-module subslot 0/0/1 shutdown command.

Hard OIR

Hard OIR is the physical online insertion and removal of Modular port adapters (MPAs) without software commands. Four types of hard OIR are supported:

  • If the bay is empty when the Cisco ASR 9001 router modular line card (MLC) boots you can do the following:

    • Insert a 20 GE MPA

    • Remove and then insert a replacement 20 GE MPA

  • If the MLC boots with a 20 GE MPA in the bay you can remove and then insert a replacement 20 GE MPA

  • If the MLC boots with a 4 10-GE MPA in the bay you can remove and then insert a replacement 4 10-GE MPA

  • If the MLC boots with a 2 10-GE MPA in the bay you can remove and then insert a replacement 2 10-GE MPA


Note
Only replacement with same types of MPA is supported by Managed OIR and Hard OIR. To replace with a different MPA type, reload the router. An empty bay during the Cisco ASR 9001 Router modular line card (MLC) bootup defaults to 20 GE MPA mode.

Installing and Removing Modular Port Adapters

These sections describe how to install or remove modular port adapters (MPAs) on the Cisco ASR 9001 Router.

Handling Modular Port Adapters (MPAs)

Each modular port adapter (MPA) circuit board is mounted on a metal carrier, and is sensitive to electrostatic discharge (ESD) damage. Before you begin installation, refer to the Cisco ASR 9000 Series Aggregation Services Router Ethernet Line Card Installation Guide for a list of parts and tools required for installation.


Caution

Always handle the modular port adapter (MPA) by the carrier edges and handle; never touch the modular port adapter (MPA) components or connector pins. (see the following figure.)

When a bay is not in use, a blank ASR 9000 MPA Slot Filler (A9K-MPA-FILR) must fill the empty bay to allow the router to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed modules. If you plan to install a modular port adapter (MPA) in a bay that is not in use, you must first remove the blank.

Figure 9. Handling a Modular Port Adapter (MPA)

Modular Port Adapter (MPA) Installation and Removal

This section provides step-by-step instructions for removing and installing a modular port adapter (MPA).


Caution

When performing these procedures, wear a grounding wrist strap to avoid ESD damage to the modular port adapter (MPA). Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself.

To remove and install a modular port adapter (MPA), perform these steps:

Procedure

Step 1

To insert the MPA, carefully slide the MPA all the way until it stops.

Note

 
The modular port adapter (MPA) will slide easily into the slot if it is properly aligned on the tracks. If MPA does not slide easily, do NOT force it. Remove the MPA and reposition it, paying close attention to engaging it on the tracks.

Step 2

To fully seat the MPA, use a number 2 Phillips screwdriver to tighten the jackscrew on the MPA.

Note

 
Avoid over torquing the modular port adapter (MPA) jackscrew when installing the MPA. Tighten the jackscrew on the MPA to a torque of 17 +/-1 inch-pound. Do not use a power screwdriver to tighten the MPA jackscrew.

Step 3

To remove the MPA, use a number 2 Phillips screwdriver to loosen the lock screw on the MPA. Make sure that the cables are disconnected from the MPA first.

Step 4

Grasp the MPA and pull the MPA from the slot.

Optical Device Installation and Removal

Any contamination of the fiber connection can cause failure of the component or failure of the whole system. A particle that partially or completely blocks the core generates strong back reflections, which can cause instability in the laser system. Inspection, cleaning, and reinspection are critical steps to take before making fiber-optic connections.

Checking the Installation

This section describes the procedures you can use to verify the modular port adapter (MPA) installation, and includes information on these topics:

Verifying the Installation

This section describes how to verify the modular port adapter (MPA) installation by observing the MPA LED states.

When the system has reinitialized all interfaces, the MPA STATUS LEDs should be on (green). The port LEDs (C/A and A/L) may be on (green), depending on your connections and configuration.

To verify that a MPA is installed correctly:

Procedure

Step 1

Observe the console display messages and verify that the system discovers the modular line card (MLC), while the system reinitializes each interface, thus:

  • As the MPA is initialized, the STATUS LED will first be amber, indicating that power is on. When the modular port adapter card (MPA) is active, the STATUS LED will illuminate green.

Step 2

When the MPA STATUS LEDs are green, all associated interfaces are configurable.

  • If a MPA is replaced with a module of the same type (as in an OIR or hardware swap), the previous configuration is reinstated when the MPA becomes active.
  • If a MPA was not previously installed in the same slot or subslot, then the configuration for all associated interfaces is empty.

Note

 
New interfaces are not made available until you configure them.

Step 3

If the modular port adapters (MPAs) do not become active within three minutes, refer to the system console messages. If there is no indication that a field-programmable device (FPD) upgrade is underway, see Troubleshooting the Installation section.

Using show Commands to Verify Modular Port Adapter (MPA) Status

This procedure uses show commands to verify that the new modular port adapters (MPAs) are configured and operating correctly.

To verify the MPA status:

Procedure

Step 1

Use the show running-config command to display the system configuration. Verify that the configuration includes the new MPA interfaces.

Step 2

Use the show diag command to display information about the installed modular line cards (MLCs).

Step 3

Use the show hw-module fpd location <rack/slot/subslot> command to verify the FPD version information of the MPAs installed in the system.

Note

 
If a modular port adapter (MPA) does not meet the minimum version required, the FPD may need to be updated. See the Cisco ASR 9000 Series Aggregation Services Router System Management Configuration Guide for instructions. If the update fails, the failing module is powered down and an error message displays on the system console

Step 4

Use the show platform command to check the state of all boards in the chassis, including the MLC and the MPAs.

The MPA state should be “OK” and the MLC state should be “IOS XR RUN” in the show platform command output.

Step 5

Use the show version command to obtain software version information for the installed MLCs as well as interfaces available.

Using show Commands to Display Modular Port Adapter (MPA) Information

The following table describes the show commands you can use to display modular port adapter (MPA) information.

Table 5. show Commands to Display Modular Port Adapter (MPA) Information

Using the ping Command to Verify Network Connectivity

The ping command allows you to verify whether a modular port adapter (MPA) port is functioning properly and to check the path between a specific port and connected devices at various locations on the network.

After you verify that the system and the modular line card (MLC) have booted successfully and are operational, you can use the ping command to verify the status of the MPA ports. See the Cisco ASR 9000 Series Aggregation Services Router Getting Started Guide and the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Configuration Guide for more information on bringing up and configuring the Cisco ASR 9000 Series Router and the Cisco ASR 9000 A9K-MOD80G-H.

The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate that the connection failed.

This is an example of a successful ping command to a remote server with the IP address 10.1.1.60: 


Router# ping 10.1.1.60 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.1.1.60, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#

If the connection fails, verify that you have the correct IP address for the destination device and that the destination device is active (powered on), and then repeat the ping command.

Cable Management

The Cisco ASR 9902 Router, Cisco ASR 9903 Router, Cisco ASR 9901 Router, and Cisco ASR 9001 Router includes a cable-management system that organizes the interface cables entering and exiting the router, keeping them out of the way, and free of sharp bends.

Caution
The ports labeled Ethernet, Console, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits.

Note
RP cables are not available from Cisco, but they are available from external commercial cable vendors.

Note
To comply with the intra-building lightning surge requirements of Telecordia GR-1089-CORE, Issue 6, you must use a shielded cable when connecting to the Ethernet ports. The shielded cable is terminated by shielded connectors on both ends, with the cable shield material tied to both connectors.

Connecting to the RP Console Port

The system console port on the RP is an RJ-45 receptacle for connecting a data terminal to perform the initial configuration of the router. Depending on the cabling pinout on the terminal server end, the console port will require either a crossover cable or a straight-through RJ-45 cable. See Port Connection Guidelines for additional information about the console port.

See the previous and follow these steps to connect a data terminal to the RP console port:

Connecting to the RP Ethernet Management Ports

To connect cables to the RP management ports, attach STP (Shielded Twisted Pair) cables directly to the MGT LAN 0 and MGT LAN 1 RJ-45 receptacles on the RP. STP cables are required to meet NEBS requirements. See Management LAN Ports Connection Guidelines for additional information about the Ethernet management LAN ports.


Note
RJ-45 cables are not available from Cisco Systems; they are available from external commercial cable vendors. Use cables that comply with EIA/TIA-568 standards.

Caution

Ethernet management ports are primarily used as Telnet ports into the Cisco ASR 9001, and for booting or accessing Cisco software images over a network to which an Ethernet port is directly connected. We strongly caution you to consider the security implications of enabling routing functions on these ports.


Note
The Ethernet interfaces on the RP are end-station devices only, not repeaters.

Use this procedure to connect an Ethernet cable to the RP RJ-45 Ethernet receptacle:

Procedure

Step 1

Plug the cable directly into the RJ-45 receptacle.

Step 2

Connect the network end of your RJ-45 cable to a switch, hub, repeater, or other external equipment.

OIR enables users to replace a defective module without interrupting router operations. It is now possible to replace the 0.8T PEC in the Cisco ASR 9903 router without any traffic disruption.

For more information on:

The Cisco A9903-8HG-PEC is an optional removable module that offers 48 physical ports with maximum 800G data bandwidth capacity. Here are few physical features of this module:

  • It offers two sets of port combinations:

    • forty-eight 10GE SFP+

    • thirty-two 25GE SFP28 ports

  • The ports are grouped in slice 4 and slice 5. These slices are marked in blue and purple as shown in the following image.


    Note

    A slice is a logical grouping of physical ports.

  • You can configure both slices in:

    • 10GE mode or 25GE mode. For example, slice 4 and slice 5 in 25GE mode.

    • a mix of 10GE and 25GE mode. For example, slice 4 in 10GE and slice 5 in 25GE mode.

  • By default, all 48 ports are in 10GE mode. To change the port-mode to 25GE mode, use hw-module location <node> slice <number> config-mode command. For more information, see Configuring Port Modes in 0.8T PEC.

  • It supports line-rate MACSec on 10GE and 25GE.

Connecting Power to the Router

Use one of these procedures to connect power to your router.


Note

On the Cisco ASR 9902 router you must first install the PSUs and then follow any of the below procedures to connect power to the router


Caution

A router must be operated with all its power modules installed at all times for electromagnetic compatibility (EMC).

Connecting Power to an AC-Powered Router

Use this procedure to connect the AC power cords to the router.


Note
Connect each AC power supply to a dedicated power source (branch circuit). Each AC-input power supply operates at a nominal input level of 100 to 240 VAC and requires at least a 15 A service for use in North America and Japan, or a 10 A service for international use. For more information on AC power input levels, see Power Connection Guidelines.

Procedure

Step 1

Check that the power switch at the front (or at the rear for Cisco ASR 9902) of the chassis is set to the OFF position.

Step 2

Check that the circuit breaker assigned to the AC power source you are connecting is set to OFF.

Step 3

Connect the permanent ground connection (central office grounding system) to the NEBS grounding location on the router chassis.

Note

 
To ensure that power remains off while you are performing this procedure, turn the circuit breaker switch in the off (0) position until you are ready to turn it on.

Step 4

Do one of the following:

  • Cisco ASR 9903: Plug the AC power cord into the receptacle at the rear of the chassis (see the following figure).

  • Cisco ASR 9901: Plug the AC power cord into the receptacle at the rear of the chassis (see the following figure).

  • Cisco ASR 9001: Plug the AC power cord into the receptacle at the front of the chassis (see the following figure).

Step 5

Close the cable wrap to secure the AC power cord plug to the power module receptacle.

Step 6

Plug the other end of the AC power cord into the AC source receptacle.

Step 7

Proceed to Powering on the Router.

Connecting Power to a DC-Powered Router

This section contains the procedures to connect the DC source power cables to a DC-powered router.

The color coding of source DC power cable leads depends on the color coding of the site DC power source. Because there is no color code standard for source DC wiring, you must be sure that power source cables are connected to the power module with the proper positive (+) and negative (–) polarity:

  • In some cases, the source DC cable leads might have a positive (+) or a negative (–) label. This is a relatively safe indication of the polarity, but you must verify the polarity by measuring the voltage between the DC cable leads . Be sure that the positive (+) and negative (–) cable leads match the positive (+) and negative (–) labels on the power module when making the measurement.

  • Green (or green and yellow) cable typically indicates that it is a ground cable.


Caution
DC power modules contain reverse voltage protection circuitry to prevent damage to the module if it detects a reverse polarity condition. No damage should occur from reverse polarity, but you should correct a reverse-polarity condition immediately.

Note
The length of the cables depends on the location of your router in relation to the source of DC power. These cables are not available from Cisco Systems. They are available from external commercial cable vendors. For more information on site power and source DC cable requirements, see Power Connection Guidelines.

Note
To ensure that power remains off while you are performing this procedure, follow proper lockout /tagout procedures as defined by your company in accordance with local and national laws.

Use this procedure to connect the DC source power cables to a DC power module:

Procedure

Step 1

Verify that the power switch is set to the OFF position.

Step 2

Connect the DC power cables in the following order (see the figure below):

  1. Positive cables first.

  2. Negative cable last.

Step 3

Repeat Step 2 for the other power modules installed in the chassis.

Caution

 
To prevent injury and damage to the equipment, always attach the ground and source DC power cable to power module terminals in the following order: (1) ground to ground, (2) positive (+) to positive (+), (3) negative (–) to negative (–).
