Preparing for Server Installation

Rack Requirements

This section provides the requirements for the standard open racks. The rack must be of the following type:

• A standard 19-in. (48.3-cm) wide, four - post EIA rack, with mou nting p osts that conform t o 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 one RU, equal to 1.75 in. (44.45 mm).

Equipment Requirements

The slide rails supplied by Cisco Systems for this server do not require tools for installation. The inner rails (mounting brackets) are pre-attached to the sides of the server.

Chapter 2 Installing the Server

Installing the Server In a Rack

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

Step 1 Open the front securing latch (see Figure 2-2). The end of the slide-rail assembly marked “FRONT” has

a spring-loaded securing latch that must be open before you can insert the mounting pegs into the rack-post holes.

a. On the rear side of the securing-latch assembly, hold open the clip marked “PULL.” b. Slide the spring-loaded securing latch away from the mounting pegs. c. Release the clip marked “PULL” to lock the securing latch in the open position.

Figure 2-2 Front Securing Latch

Installing the Server In a Rack

1 Clip marked “PULL” on rear of assembly 3 Spring-loaded securing latch on front of

assembly

2 Front mounting pegs

Step 2 Install the slide rails onto the rack:

a. Position a slide-rail assembly inside the two left-side rack posts (see Figure 2-3).

Use the “FRONT” and “REAR” markings on the slide-rail assembly to orient the assembly correctly with the front and rear rack posts.

b. Position the front mounting pegs so that they enter the desired front rack-post holes from the front.

Note The mounting pegs that protrude through the rack-post holes are designed to fit round or square holes,

or smaller #10-32 round holes when the mounting peg is compressed. If your rack has #10-32 rack-post holes, align the mounting pegs with the holes and then compress the spring-loaded pegs to expose the #10-32 inner peg.

c. Expand the length-adjustment bracket until the rear mounting pegs protrude through the desired

holes in the rear rack post.

Use your finger to hold the rear securing latch open when you insert the rear mounting pegs to their holes. When you release the latch, it wraps around the rack post and secures the slide-rail assembly.

Initial Server Setup

This section includes the following topics:

• Connecting and Powering On the Server (Standalone Mode), page 2-8

• NIC Modes and NIC Redundancy Setting s, page 2-10

Connecting and Powering On the Server (Standalone Mode)

Note The server is shipped with a default NIC mode called Shared LOM EXT, default NIC redundancy is

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 In that step, you can also change the NIC redundancy and set static IP settings.

Step 3 of the following procedure.

Chapter 2 Installing the Server

Use the following procedure to perform initial setup of the server:

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

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

You can verify power status by looking at the Power Status LED (see Figure 1-1 on page 1-2):

• 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 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 to the server.

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

redundancy settings:

–

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 utilized simultaneously.

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 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.

Using the BIOS Recovery Header CN34

Depending on which stage the BIOS becomes corrupted, you might see different behavior.

• If the BIOS BootBlock is corrupted, you might see the system get stuck on the following message:

Initializing and configuring memory/hardware

• If it is a non-BootBlock corruption, the following message is displayed:

****BIOS FLASH IMAGE CORRUPTED**** Flash a valid BIOS capsule file using CIMC WebGUI or CLI interface. IF CIMC INTERFACE IS NOT AVAILABLE, FOLLOW THE STEPS MENTIONED BELOW.

1. Connect the USB stick with recovery.cap file in root folder.

2. Reset the host. IF THESE STEPS DO NOT RECOVER THE BIOS

1. Power off the system.

2. Mount recovery jumper.

3. Connect the USB stick with recovery.cap file in root folder.

4. Power on the system. Wait for a few seconds if already plugged in the USB stick. REFER TO SYSTEM MANUAL FOR ANY ISSUES.

Note As indicated by the message show n above , there are two procedures for recove ring the BIOS. Try

procedure 1 first, then if that does not recove r the BIOS , use procedure 2.

Note The server must have CIMC version 1.4(6) or later to use these procedures.

Procedure 1: Reboot With recovery.cap File

Step 1 Download the BIOS update package and extract it to a temporary location. Step 2 Copy the contents of the extracted recovery folder to the root directory a USB thumb drive. The

recovery folder contains the recovery.cap file that is required in this procedure.

Note The recovery.cap file must be in the root directory of the USB thumb drive. Do not rename this

Service Headers and Jumpers

Using the Clear CMOS Header CN14

See Figure 2-5 for the location of this header. You can jumper this header to clear the server’s CMOS

settings in the case of a system hang. For example, if the server hangs because of incorrect settings and does not boot, use this jumper to invalidate the settings and reboot with defaults.

Caution Clearing the CMOS removes any customized settings and might result in data loss. Make a note of any

necessary customized settings in the BIOS before you use this clear CMOS procedure.

Step 1 Power off the server as described in Shutting Down and Powering Off the Server, page 3-6. Step 2 Disconnect all power cords from the power supplies. Step 3 Slide the server out the front of the rack far enough so that you can remove the top cover. You might have

Observe the following guidelines when installing or replacing DIMMs:

• Each CPU supports three memory channels.

–

CPU1 supports channels A, B, and C.

–

CPU2 supports channels D, E, and F

Note In a single-CPU system, the maximum number of DIMMs is six (only the six slot s supported

by CPU1).

• Each channel has two DIMM slots (for example, channel A = slots A0 and A1).

–

A channel can operate with one or two DIMMs installed.

–

If a channel has only one DIMM, populate slot 0 first (the blue slot).

• When both CPUs are installed, populate the DIMM slots of each CPU identically.

–

Fill blue slots in the channels first: A0, D0, B0, E0, C0, F0

–

Fill black slots in the channels second: A1, D1, B1, E1, C1, F1

• Any DIMM installed in a DIMM socket for which the CPU is absent is not recognized. In a

single-CPU configuration, populate the channels for CPU1 only.

• Although 1600 MHz DIMMs can be run in Power Savings Mode (1.35 V operation), 1600 MHz

operation is supported only when the DDR mode is set to Performance Mode (see “

Low-Voltage DIMM Operation.”) A 1600 MHz DIMM set to Power Savings Mode operates at

1066 MHz.

• Observe the DIMM mixing rules shown in Table 3-3.

Memory Mirroring

When memory mirroring is enabled, the memory subsy stem simultan eously wr ites identi cal data t o two channels. If a memory read from one of the channels returns incorrect data due to an uncorrectable memory error, the system automatically retrieves the data from the other channel. A transient or soft error in one channel does not affect the mirrored data, and operation continues unless there is a simultaneous error in exact ly the same location on a DIMM and its mirrored DIMM. Memory mirroring reduces the amount of memory available to the operating system by 50% because only one of the two populated channels provides data.

If you choose to enable memory mirroring, populate the DIMM slots in the order shown in Table 3-4 or

Table 3-5.

Replacing CPUs and Heatsinks

This server can have up to two CPUs. Each CPU supports three DIMM channels (six DIMM slots). See

Figure 3-12. This section includes the following topics:

• Single-CPU Restrictions, page 3-24

• CPU Replacement Procedure, page 3-24

Single-CPU Restrictions

The minimum configuration is that the server must have at least CPU1 installed. Install CPU1 first, then CPU2.

The following restrictions apply when using a single-CPU configuration:

• The maximum number of DIMMs is six (only the six slots controlled by CPU1 are active).

• PCIe riser 2 is unavailable (PCIe slots 3, 4, and 5).

CPU Replacement Procedure

Caution CPUs and their motherboard sockets are fragile and must be handled with care to avoid damaging pins

during installation. The CPUs must be installed with heatsinks and their thermal pads to ensure proper cooling. Failure to install a CPU correctly might result in damage to the server.

3-24

Caution The Pick-and-Place tools used in this procedure are required to prevent da mage to the contact pins

between the motherboard and the CPU. Do not attempt this procedure without the required tools, which are included with each CPU option kit. If you do not have the tool, you can order a spare (Cisco PID UCS-CPU-EN-PNP).

Chapter 3 Maintaining the Server

Installing Multiple PCIe Cards and Resolving Limited Resources

When a large number of PCIe add-on cards are installed in the server, the system may run out of the following resources required for PCIe devices:

• Option ROM memory space

• 16-bit I/O space

The topics in this section provide guidelines for resolving the issues related to these limited resources.

• Resolving Insufficient Memory Space to Execute Option ROMs, page 3-37

• Resolving Insufficient 16-Bit I/O Space, page 3-38

Resolving Insufficient Memory Space to Execute Option ROMs

The system has very limited memory to execute PCIe legacy option ROMs, so when a large number of PCIe add-on cards are installed in the server, the system BIOS might not able to execute all of the option ROMs. The system BIOS loads and executes the option ROMs in the order that the PCIe cards are enumerated (Slot 1, Slot 2, Slot 3, etc.).

If the system BIOS does not have sufficient memory sp ace to load any PCIe option ROM, it skips loading that option ROM, reports a system event log (SEL) event to the CIMC controller and reports the following error in the Error Manager page of the BIOS Setup utility:

ERROR CODE SEVERITY INSTANCE DESCRIPTION 146 Major N/A PCI out of resources error.

Major severity requires user intervention but does not prevent system boot.

Installing or Replacing Server Components

T o resolve this issue, disable the Option ROMs that are not needed for system booting. The BIOS Setup Utility provides the setup options to enable or disable the Option ROMs at the PCIe slot level for the PCIe expansion slots and at the port level for th e onboard NICs. These options can be found in the BIOS Setup Utility Advanced PCI Configuration page.

• Guidelines for RAID controller booting:

If the server is configured to boot primarily from RAID storage, make sure that the option ROMs for the slots where your RAID controllers installed are enabled in the BIOS, depending on your RAID controller configuration.

If the RAID controller does not appear in the system boot or der even with the option ROMs for those slots are enabled, the RAID controller option ROM might not have sufficient memory space to execute. In that case, disable other option ROMs that are not needed for the system configuration to free up some memory space for the RAID controller option ROM.

• Guidelines for onboard NIC PXE booting:

If the system is configured to primarily perform PXE boot from onboard NICs, make sure that the option ROMs for the onboard NICs to be booted from are enabled in the BIOS Setup Utility. Disable other option ROMs that are not needed to create sufficient memory space for the onboard NICs.

OL-26647-01z

Cisco UCS C24 Server Installation and Service Guide

3-37

Installing or Replacing Server Components

Resolving Insufficient 16-Bit I/O Space

The system has only 64 KB of legacy 16-bit I/O resources available. This 64 KB of I/O space is divided between the CPUs in the system because the PCIe controller is integrated into the CPUs. This server BIOS has the capability to dynamically detect the 16-bit I/O resource requirement for each CPU and then balance the 16-bit I/O resource allocation between the CPUs accordingly during the PCI bus enumeration phase of the BIOS POST.

When a large number of PCIe cards are installed in the system, the system BIOS might not have sufficient I/O space for some PCIe devices. If the system BIOS is not able to allocate the required I/O resources for any PCIe devices, the following symptoms have been observed:

• The system might get stuck in an infinite reset loop.

• The BIOS might appear to hang while initializing PCIe devices.

• The PCIe option ROMs might take excessive time to complete, which appears to lock up the system.

• PCIe boot devices might not be accessible from the BIOS.

• PCIe option ROMs might report initialization errors. These errors are seen before the BIOS passes

control to the operating system.

• The keyboard might not work.

To work around this problem, rebalance the 16-bit I/O load using the following methods:

1. Physically remove any unused PCIe cards.

Chapter 3 Maintaining the Server

2. If the system has one or more Cisco virtual interface cards (VICs) installed, disable the PXE boot

on the VICs that are not required for th e system boot configuration by using the Network Adapters page in the CIMC WebUI to free up some 16-bit I/O resources. Each VIC uses a minimum 16 KB of 16-bit I/O resource, so disabling PXE boot on Cisco VICs would free up some 16-bit I/O resources that can be used for other PCIe cards that are installed in the system.

Intel TXT provides greater protection for information that is used and stored on the business server. A key aspect of that protection is the p rovisio n of an isolated execution environment and associated sections of memory where operations can be conducted on sensitive data, invisibly to the rest of the system. Likewise, Intel TXT provides for a sealed portion of storage where sensitive data such as encryption keys can be kept, helping to shield them from being compromised during an attack by malicious code.

To enable the TXT feature, follow these steps:
