Preparing for Server Installation

Rack Requirements

This section provides the requirements for the standard open racks, assuming an external ambient air temperature range of 41° F to 95° F (5° C to 35° C).

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 supplied slide rails.

• The minimum vertical rack space per server must be two RUs, equal to 3.5 in. (88.9 mm).

Equipment Requirements

The slide rails supplied by Cisco Systems for this server do not require tools for installation if you install them in a rack that has square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), or #12-24 UNC threaded holes. The inner rails (mounting brackets) are preattached to the sides of the server.

However, if you install the slide rails in a rack that has #10-32 round holes, a flat-bladed screwdriver is required to remove the larger square or round mounting pegs from the front of the slide rails.

Installing the Server In a Rack

This section describes how to install the server in a rack.

Installing the Server In a Rack

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. If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Statement 1006

To install the slide rails and the server into a rack, follow these steps:

Step 1 Install the slide rails into the rack (see Figure 2-2):

a. Align the slide-rail assembly inside the rack posts with the length-adjustment bracket (Figure 2-2,

item 4) toward the rear of the rack.

b. Compress the length-adjustment bracket until the mounting pegs (item 5) and locking clips (item 6)

on the slide-rail assembly engage the desired rack holes on the front and rear rack posts:

–

The mounting pegs fit square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), or #12-24 UNC threaded holes. They fit the shape of the hole when the pegs are compressed.

–

The smaller #10-32 round mounting pegs are enclosed in the center of the compressible rear pegs. However, to use the #10-32 pegs, you must use a flat-bladed screwdriver to remove the square or round front pegs.

active-active, and DHCP is enabled. Shared LOM EXT mode enables the 1-Gb Ethernet ports and the ports on any installed Cisco virtual interface card (VIC) to access the Cisco Integrated Management Interface (CIMC). If you want to use the 10/100 dedicated management ports to access the CIMC, you can connect to the server and change the NIC mode as described in Step 4 of the following procedure. In that step, you can also change the NIC redundancy and set static IP settings.

Chapter 2 Installing the Server

To perform initial setup of the server, follow these steps:

Step 1 Attach a supplied power cord to each power supply in your server, and then attach the power cord to a

grounded AC power outlet. See the Power Specifications, page A-2 for power specifications.

Wait for approximately two minutes to let the server boot in standby power during the first bootup.

You can verify the power status by looking at the Power Status LED (see Figure 1-1 on page 1-1):

• Off—There is no AC power present in the server.

• Amber—The server is in standby power mode. Power is supplied only to the CIMC and some

motherboard functions.

• Green—The server is in main power mode. Power is supplied to all server components.

Note During bootup, the server beeps once for each USB device that is attached to the server. Even if

there are no external USB devices attached, there is a short beep for each virtual USB device such as a virtual floppy drive, CD/DVD drive, keyboard, or mouse. A beep is also emitted if a USB device is hot-plugged or hot-unplugged during a BIOS power-on self test (POST), or while you are accessing the BIOS Setup utility or the EFI shell.

Step 2 Connect a USB keyboard and VGA monitor by connecting the supplied KVM cable to the KVM

connector on the front panel (see Figure 1-1 on page 1-1).

2-8

Note Alternatively, you can use the VGA and USB ports on the rear panel. However, you cannot use

the front panel VGA and the rear panel VGA at the same time. If you are connected to one VGA connector and you then connect a video device to the other connector, the first VGA connector is disabled.

Step 3 Connect Ethernet cables to the server ports or card ports that you want to use.

setting, along with Active-active NIC redundancy and DHCP-enabled. With this mode, the shared LOM and Cisco Card interfaces are both enabled.

In this 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 server 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 the CIMC through a Cisco card in standalone mode.

redundancy and IP setting.

• Cisco Card—The ports on an installed Cisco UCS virtual interface card (VIC) are used to access the

CIMC. You must select a NIC redundancy and IP setting.

Note Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in PCIe

slot 1, 4, or 7. See also Special Considerations for Cisco UCS Virtual Interface Cards, page 3-45.

d. Use this utility to change the NIC redundancy to your preference. This server has three possible NIC

redundancy settings:

–

None—(Available only with the Shipping NIC mode) The Ethernet ports operate independently and do not fail over if there is a problem.

–

Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.

–

Active-active—All Ethernet ports are used simultaneously. See NIC Modes and NIC

Redundancy Settings, page 2-11 for more information.

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

Note Before you enable DHCP, your DHCP server must be preconfigured with the range of MAC

addresses for this server. The MAC address is printed on a label on the rear of the server. This server has a range of six MAC addresses that are assigned to the CIMC. The MAC address printed on the label is the beginning of the range of six contiguous MAC addresses.

f. (Optional) Use this utility to make VLAN settings, and to set a default CIMC user password.

OL-27640-01

Note Changes to the settings take effect after approximately 45 seconds. Press F5 to refresh the screen

and wait until the new settings appear before you reboot the server in the next step.

g. Press F10 to save your settings and reboot the server.

NIC Modes and NIC Redundancy Settings

This server has the following NIC mode settings that you can choose from:

• Shared LOM EXT (default)—This is shared LOM extended mode. This is the factory default setting,

along with Active-active NIC redundancy and DHCP-enabled. With this mode, the shared LOM and Cisco Card interfaces are both enabled.

Note In this 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 server is in standalone mode, further DHCP requests from the Cisco card are disabled. If the system determines that the Cisco card connection is getting its IP address from a Cisco UCS Manager system, the reply has parameters that automatically move the server to UCSM mode.

• Dedicated—The 10/100 management port is used to access the CIMC. You must select a NIC

redundancy and IP setting.

• Shared LOM—The 1-Gb Ethernet ports are used to access the CIMC. You must select a NIC

redundancy and IP setting.

• Cisco Card—The ports on an installed Cisco UCS virtual interface card (VIC) are used to access the

CIMC. You must select a NIC redundancy and IP setting.

Initial Server Setup

Note The Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in

PCIe slot 1, 4, or 7. See also Special Considerations for Cisco UCS Virtual Interface Cards,

page 3-45.

This server has the following NIC redundancy settings that you can choose from:

• None—The Ethernet ports operate independently and do not fail over if there is a problem.

• Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.

• Active-active—All Ethernet ports are used simultaneously.

The active/active setting uses Mode 5 or Balance-TLB (adaptive transmit load balancing). This is channel bonding that does not require any special switch support. The outgoing traffic is distributed according to the current load (computed relative to the speed) on each slave. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave.
