Installation Warnings and Guidelines


Note

Before you install, operate, or service a server, review the Regulatory Compliance and Safety Information for Cisco UCS C-Series Servers for important safety information.


Warning

IMPORTANT SAFETY INSTRUCTIONS

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device.

Statement 1071

Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of: 35° C (95° F).

Statement 1047

Warning

The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device.

Statement 1019

Warning

This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 250 V, 15 A.

Statement 1005

Warning

Installation of the equipment must comply with local and national electrical codes.

Statement 1074

Warning

This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock, and key, or other means of security.

Statement 1017

Caution

To ensure proper airflow it is necessary to rack the servers using rail kits. Physically placing the units on top of one another or “stacking” without the use of the rail kits blocks the air vents on top of the servers, which could result in overheating, higher fan speeds, and higher power consumption. We recommend that you mount your servers on rail kits when you are installing them into the rack because these rails provide the minimal spacing required between the servers. No additional spacing between the servers is required when you mount the units using rail kits.


Caution

Avoid uninterruptible power supply (UPS) types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco UCS, which can have substantial current draw fluctuations from fluctuating data traffic patterns.

When you are installing a node, use the following guidelines:

  • Plan your site configuration and prepare the site before installing the node. See the Cisco UCS Site Preparation Guide for the recommended site planning tasks.

  • Ensure that there is adequate space around the node to allow for accessing the node and for adequate airflow. The airflow in this node is from front to back.

  • Ensure that the air-conditioning meets the thermal requirements listed in the Environmental Specifications.

  • Ensure that the cabinet or rack meets the requirements listed in the Rack Requirements.

  • Ensure that the site power meets the power requirements listed in the Power Specifications. If available, you can use an uninterruptible power supply (UPS) to protect against power failures.

Rack Requirements

The rack must be of the following type:

  • A standard 19-in. (48.3-cm) wide, four-post EIA rack, with mounting posts that conform to English universal hole spacing, per section 1 of ANSI/EIA-310-D-1992.

  • The rack-post holes can be square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), #12-24 UNC, or #10-32 UNC when you use the Cisco-supplied slide rails.

  • The minimum vertical rack space per node must be one rack unit (RU), equal to 1.75 in. (44.45 mm).

Supported Cisco Slide Rail Kits

The node supports the following rail kit options:

  • Cisco part HX-RAILB-M6= (ball-bearing slide rail kit)

  • Cisco part HX-RAILF-M6= (friction slide rail kit)

  • Cisco part HX-CMAF-M6= (cable management arm)

Rack Installation Tools Required

The slide rails sold by Cisco Systems for this node do not require tools for installation.

Slide Rail and Cable Management Arm Dimensions

The slide rails for this node have an adjustment range of 24 to 36 inches (610 to 914 mm).

The optional cable management arm (CMA) adds additional length requirements:

  • The additional distance from the rear of the node to the rear of the CMA is 5.4 inches (137.4 mm).

  • The total length of the node including the CMA is 35.2 inches (894 mm).

Installing the Node in a Rack

This section describes how to install the node in a rack using the supported rail kit (HX-RAIL-M6) that is sold by Cisco.


Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

Step 9

Continue with Setting Up the System With the Cisco IMC Configuration Utility.

Setting Up the System With the Cisco IMC Configuration Utility

Before you begin

The following procedure is performed after you connect to the system and open the Cisco IMC Configuration Utility.

Procedure

Step 1

Set the NIC mode to choose which ports to use to access Cisco IMC for node management:

  • Shared LOM EXT (default)—This is the shared LOM extended mode, the factory-default setting. With this mode, the Shared LOM and Cisco Card interfaces are both enabled. You must select the default Active-Active NIC redundancy setting in the following step.

    In this NIC mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If the system determines that the Cisco card connection is not getting its IP address from a Cisco UCS Manager system because the node is in standalone mode, further DHCP requests from the Cisco card are disabled. Use the Cisco Card NIC mode if you want to connect to Cisco IMC through a Cisco card in standalone mode.

  • Shared LOM—The 1-Gb/10-Gb Ethernet ports are used to access Cisco IMC. You must select either the Active-Active or Active-standby NIC redundancy setting in the following step.

  • Dedicated—The dedicated management port is used to access Cisco IMC. You must select the None NIC redundancy setting in the following step.

  • Cisco Card—The ports on an installed Cisco UCS Virtual Interface Card (VIC) are used to access the Cisco IMC. You must select either the Active-Active or Active-standby NIC redundancy setting in the following step.

    See also the required VIC Slot setting below.

  • VIC Slot—Only if you use the Cisco Card NIC mode, you must select this setting to match where your VIC is installed. The choices are Riser1, Riser2, or Flex-LOM (the mLOM slot).

    • If you select Riser1, you must install the VIC in slot 1.

    • If you select Riser2, you must install the VIC in slot 2.

    • If you select Flex-LOM, you must install an mLOM-style VIC in the mLOM slot.
Step 2

Set the NIC redundancy to your preference. This node has three possible NIC redundancy settings:

  • None—The Ethernet ports operate independently and do not fail over if there is a problem. This setting can be used only with the Dedicated NIC mode.

  • Active-standby—If an active Ethernet port fails, traffic fails over to a standby port. Shared LOM and Cisco Card modes can each use either Active-standby or Active-active settings.

  • Active-active (default)—All Ethernet ports are utilized simultaneously. The Shared LOM EXT mode must use only this NIC redundancy setting. Shared LOM and Cisco Card modes can each use either Active-standby or Active-active settings.

Step 3

Choose whether to enable DHCP for dynamic network settings, or to enter static network settings.

Note 

Before you enable DHCP, you must preconfigure your DHCP node with the range of MAC addresses for this node. The MAC address is printed on a label on the rear of the node. This node has a range of six MAC addresses assigned to Cisco IMC. The MAC address printed on the label is the beginning of the range of six contiguous MAC addresses.

The static IPv4 and IPv6 settings include the following:

  • The Cisco IMC IP address.

    For IPv6, valid values are 1 - 127.

  • The gateway.

    For IPv6, if you do not know the gateway, you can set it as none by entering :: (two colons).

  • The preferred DNS node address.

    For IPv6, you can set this as none by entering :: (two colons).
Step 4

(Optional) Make VLAN settings.
Step 5

Press F1 to go to the second settings window, then continue with the next step.

From the second window, you can press F2 to switch back to the first window.

Step 6

(Optional) Set a hostname for the node.
Step 7

(Optional) Enable dynamic DNS and set a dynamic DNS (DDNS) domain.
Step 8

(Optional) If you check the Factory Default check box, the node reverts to the factory defaults.
Step 9

(Optional) Set a default user password.

Note 
The factory default username for the node is admin. The default password is password.
Step 10

(Optional) Enable auto-negotiation of port settings or set the port speed and duplex mode manually.

Note 
Auto-negotiation is applicable only when you use the Dedicated NIC mode. Auto-negotiation sets the port speed and duplex mode automatically based on the switch port to which the node is connected. If you disable auto-negotiation, you must set the port speed and duplex mode manually.
Step 11

(Optional) Reset port profiles and the port name.
Step 12

Press F5 to refresh the settings that you made. You might have to wait about 45 seconds until the new settings appear and the message, “Network settings configured” is displayed before you reboot the node in the next step.

Step 13

Press F10 to save your settings and reboot the node.

Note 
If you chose to enable DHCP, the dynamically assigned IP and MAC addresses are displayed on the console screen during bootup.

What to do next

Use a browser and the IP address of the Cisco IMC to connect to the Cisco IMC management interface. The IP address is based upon the settings that you made (either a static address or the address assigned by your DHCP node).

Note
The factory default username for the node is admin. The default password is password.

To manage the node, see the Cisco UCS C-Series Rack-Mount Server Configuration Guide or the Cisco UCS C-Series Rack-Mount Server CLI Configuration Guide for instructions on using those interfaces for your Cisco IMC release.
