Initial Server Setup

This section contains the following topics:

• Connecting and Powering On the Server (Standalone Mode), page 2-9

• NIC Modes and NIC Redundancy Settings, page 2-12

Connecting and Powering On the Server (Standalone Mode)

Note This section describes how to power on the server, assign an IP address, and connect to server

management when using the server in standalone mode. To use the server in UCS integration, specific cabling and settings are required. See Installation for Cisco UCS Integration, page D-1.

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

active-active, and DHCP is enabled. Shared LOM mode enables the two 1Gb Ethernet ports to access the Cisco Integrated Management Interface (CIMC). If you want to use the 10/100 management ports or a Cisco network adapter card port to access the CIMC, you must first connect to the server and change the NIC mode as described in NIC redundancy and set static IP settings.

Step 3 of the following procedure. In that step, you can also change the

Initial Server Setup

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

“Power Specifications” section on page A-2 for power specifications.

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

Note Depending on how much memory is installed in the server, bootup might take two minutes or more

because of the memory verification operation during bootup. Servers with the full 384 GB of memory might take up to four minutes to boot.

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

• Off—The server is not receiving power. Check the power cord connections and the power source of

the facility.

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

motherboard functions.

• Solid 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 Use the supplied KVM cable to connect a keyboard and VGA monitor to the console connector on the

front panel (see

OL-20888-02

Figure 1-1 on page 1-1).

Note If you chose to enable DHCP, the dynamically assigned IP and MAC addresses are displayed on the

console screen during bootup.

Step 4 Connect to the CIMC for server management. Connect Ethernet cables from your LAN to the server by

using the ports that you selected by your NIC Mode setting in

Step 3. The Active-active and

Active-passive NIC redundancy settings require you to connect to two ports.

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

• Active-active—All Ethernet ports are utilized 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.

Chapter 3 Maintaining the Server

Shutting Down and Powering Off the Server

Tip If you have ordered a server with power supply redundancy (at least two power supplies), you do not

have to power off the server to replace a power supply because they are redundant and hot-pluggable. The server hard drives and fan modules are also hot-pluggable.

The server can run in two power modes:

• Main power mode—Power is supplied to all server components and any operating system on your

hard drives can run.

• Standby power mode—Power is supplied only to the service processor and the cooling fans and it

is safe to power off the server from this mode.

You can invoke a graceful shutdown or an emergency shutdown (hard shutdown) by using either of the following methods:

• Use the CIMC management interface. See either the Cisco UCS C-Series Rack-Mount Server

Configuration Guide or the Cisco UCS C-Series Rack-Mount Server CLI Configuration Guide.

• Use the Power button on the server front panel. To use the Power button, follow these steps:

Preparing for Component Installation

Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section on page 3-2).

• Green indicates that the server is in main power mode and must be shut down before it can be safely

powered off. Go to

• Amber indicates that the server is already in standby mode and can be safely powered off. Go to

Step 2.

Step 3.

Step 2 Invoke either a graceful shutdown or a hard shutdown:

Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown

of the operating system.

• Graceful shutdown—Press and release the Power button. The operating system will perform a

graceful shutdown and the server goes to standby mode, which is indicated by an amber Power Status LED.

• Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off

and immediately enter standby mode.

Step 3 Disconnect the power cords from the power supplies in your server to completely power off the server.

Installing Hard Drives and Solid State Drives

http://www.cisco.com/en/US/products/ps10493/products_data_sheets_list.html

Tip You do not have to shut down or power off the server to replace hard drives or SSDs because they are

hot pluggable.

Note Y ou can mix hard drives and solid state drives (SSDs) in the same server. However , You cannot configure

a logical volume (virtual drive) that contains a mix of hard drives and SSDs. That is, when you create a logical volume, it must contain all hard drives or all SSDs.

Note If you need to make changes to your RAID configuration after installing a drive, use the LSI

configuration utility for your mass storage device. See the

page C-1 for more information.

Installing or Replacing Components

“RAID Controller Considerations” section on

Note Cisco recommends following the industry-standard practice of using drives of the same capacity when

configuring RAID volumes. If you use drives of different capacities, the usable portion of the smallest drive will be used on all drives of the RAID volume.

Note The 500 GB SATA drives (A03-D500GC3) and the 1 TB SATA drives (A03-D1TBSATA) that are sold

with the UCS C250 M2 server are supported at 3G speeds. These are 6G drives and might possibly run faster than 3G in this server, but they are supported to run at minimum 3G speeds.

To replace or install a hot-pluggable hard drive or SSD, follow these steps:

Step 1 Remove the drive that you are replacing or remove a blank panel from an empty bay (see Figure 3-6):

a. Press the release button to expose the ejector lever. b. Pull the ejector lever toward you, and then pull the drive sled from the drive bay. c. If you are replacing an existing drive, remove the drive from the sled by removing the four screws

from the sides of the sled.

Step 2 Install a new drive:

a. Place the drive in the sled with the connectors facing the rear. b. Install the four securing screws on the sides of the sled. c. With the ejector lever still open, push the sled into the drive bay until you feel the drive stop against

the backplane.

d. Press the ejector lever flat until the lock clicks into place.

Memory Population Rules and Supported Configurations

This server uses Cisco extended memory technology. To improve performance, write operations are made simultaneously to both DIMMs of a matched pair. When considering the memory configuration of your server, consider the following items:

• Refer to Ta b le 3-3 on page 3-22 for the supported DIMM configurations and the total memory for each.

• Refer to Tabl e 3-4 on page 3-23 for the order in which DIMM pairs must be populated for each supported

configuration. Find the column for the number of DIMMs in your configuration, then read down the column to see which DIMM slots on each CPU must be populated for that configuration. Also see

Figure 3-12 on page 3-20 for DIMM slot positions.

• Both DIMMs of a pair must be installed side-by-side, under the same CPU, in matching color DIMM

sockets.

For example, to add DIMM pairs to go from a a 16-DIMM configuration to a 20-DIMM configuration, refer to

Table 3-4 on page 3-23. As the differences between the columns for the 16-DIMM and 20-DIMM

configurations indicate, you add one DIMM pair to slots B4 and B5 under CPU1 and one DIMM pair to slots E4 and E5 under CPU2.

As shown in Figure 3-12 on page 3-20, B4 and B5 are side-by-side blue slots controlled by CPU1; E4 and E5 are side-by-side blue slots controlled by CPU2.

• The two DIMMs within a DIMM pair must have the identical manufacturer, type, speed, and size. Cisco

provides spare DIMMs for this product in matched pair kits.

• We recommend you do not mix different sized DIMMs or DIMMs with different clock rates in the same

server. This causes the memory system to operate at the speed of the slowest DIMMs that are installed.

Installing or Replacing Components

• (Generation M2 only) Low-voltage (1.35 V) DIMM pairs and standard-voltage DIMM pairs (1.5 V) can

be mixed in the same server. Note that this causes the system BIOS to default to standard-voltage operation (Performance Mode). See the

Note Low voltage DIMMs are supported in Generation M2 servers only.

Low-Voltage DIMM Considerations (Generation M2 Only)

The Generation M2 of this server can be ordered with low-voltage (1.35 V) DIMM pairs or standard-voltage (1.5 V) DIMM pairs. Note the following considerations:

OL-20888-02

Cisco UCS C250 Server Installation and Service Guide

3-23

Page 60

Installing or Replacing Components

• The two low-voltage DIMMs within a DIMM pair must have the identical manufacturer, type, speed,

and size. Cisco provides spare DIMMs for this product in matched pair kits.

• Low-voltage DIMM pairs and standard-voltage DIMM pairs can be mixed in the same server. Note

that this causes the system BIOS to default to standard-voltage operation (Performance Mode). That is, the server cannot operate in Power Saving Mode unless all DIMM pairs in the server are low-voltage DIMMs.

Note CPUs that have a maximum memory frequency less than 1333 MHz support LV DIMMs

• In Generation M2 only, there is a setting in the BIOS Setup utility that you can use to change the

DDR memory mode when the server has all low-voltage DIMMs installed. To access this setting, follow these steps:

Step 1 Enter the BIOS setup utility by pressing the F2 key when prompted during bootup. Step 2 Select the Advanced tab.

Chapter 3 Maintaining the Server

operating in Power saving Mode only, and do not support Performance mode. However, if your server has one of these CPUs, monitoring output for LV DIMMs will show identical voltages for both Power Saving Mode and Performance Mode. In this case, Performance Mode is not active and its fields only mirror the values from the Power Savings Mode fields.

Step 3 Select Low Voltage DDR Mode. Step 4 In the pop-up window, select either Power Saving Mode or Performance Mode.

• Power Saving Mode–Enables low-voltage memory operation. This setting is available only if all

DIMMs installed are low-voltage DIMMs.

• Performance Mode–Disables low-voltage memory operation. If you mix low-voltage DIMM pairs

with standard-voltage DIMM pairs, the system defaults to this setting.

Step 5 Press F10 to save your changes and exit the setup utility.

Additional CPU-Related Parts To Order With RMA Replacement Motherboards

When a return material authorization (RMA) of the motherboard or CPU is done on a Cisco UCS C-series server, there are additional parts that might not be included with the CPU or motherboar d spare bill of materials (BOM). The TAC engineer might need to add the additional parts to the RMA to help ensure a successful replacement.

• Scenario 1—You are re-using the existing heatsinks:

–

Heat sink cleaning kit (UCSX-HSCK=)

–

Thermal grease kit for C250 (UCS-CPU-GREASE=)

• Scenario 2—You are replacing the existing heatsinks:

–

Heat sink (C250 M1: N20-BHTS2= or C250 M2: N20-BHTS7=)

–

Heat sink cleaning kit (UCSX-HSCK=)

A CPU heatsink cleaning kit is good for up to four CPU and heat sink cleanings. The cleaning kit contains two bottles of solution, one to clean the CPU and heatsink of old thermal interface material and the other to prepare the surface of the heatsink.

New heatsink spares have preinstalled thermal interface material covered by a small sheet of plastic. It is important to clean the old thermal interface material off of the CPU prior to installing the heatsinks. Therefore, when ordering new heatsinks it is still necessary to order the heatsink cleaning kit at a minimum.

CPU Replacement Procedure

To install or replace a CPU and heatsink, follow these steps:

Step 1 Remove an existing CPU and heatsink:

a. Power off the server as described in the “Shutting Down and Powering Off the Server” section on

page 3-9.

b. Disconnect all power cords from the power supplies. c. Slide the server out the front of the rack far enough so that you can remove the top cover. You might

have to detach cables from the rear panel to provide clearance.

Installing or Replacing Components

Caution If you cannot safely view and access the component, remove the server from the rack.

d. Remove the top cover as described in the “Removing and Replacing the Server Top Cover” section

on page 3-10.

e. Remove the clear air baffle that covers the motherboard. Loosen the six thumbscrews and then lift

the baffle up and out of the server.

f. Loosen the four captive screws that hold the heatsink to the chassis posts and lift the heatsink out of

the server (see

Note Alternate loosening or tightening each screw evenly to avoid damaging the heatsink or CPU.

g. If you plan to use this heatsink with your new CPU, clean the old thermal compound from the bottom

of the heatsink.

h. Unhook the CPU socket latch and open the CPU cover plate.

i. Lift the CPU out of the socket and set it aside on an antistatic mat or in an antistatic bag.

Chapter 3 Maintaining the Server

Figure 3-14).

Step 2 Install a CPU and heatsink:

a. Set the new CPU into the socket, being careful to orient the CPU alignment notches with the

alignment keys in the socket.

b. Close the CPU cover plate and hook the socket latch back in the locked position. c. Prepare the thermal compound, which aids heat transference between the CPU and the heatsink:

• If you are installing a new heatsink, a thermal pad comes pre-applied on the heatsink. Remove the

protective film to expose the thermal pad. Do not use the syringe of thermal compound that is shipped with a replacement CPU in this case.

• If you are using your existing heatsink, make sure that all of the old thermal compound is removed

from the underside of the heatsink. Then apply the full contents of the syringe that is supplied with the new CPU to apply thermal compound to the top of the CPU. Apply the compound as evenly as possible so that it forms an even layer when the heatsink is tightened down.

d. Align the heatsink captive screws with the chassis posts, then tighten all captive screws evenly. e. Replace the air baffle and the top cover.

f. Replace the server in the rack, replace power cords and any other cables, and then power on the

server by pressing the Power button.

Special Considerations for the Cisco UCS P81E Virtual Interface Card (N2XX-ACPCI01)

The Cisco UCS P81E Virtual Interface Card is a standard-profile, half-length, dual-port 10 Gb PCIe card with SFP+. See the following special considerations and prerequisites.

• This card is supported in server Generations M1 and M2.

• This server supports installation of up to two of these cards.

• These cards are supported only in PCIe slots D and E of this server.

Note This card must be installed in PCIe slot D to use the Cisco Card NIC mode (see Figure 3-17 on

page 3-33). See also NIC Modes and NIC Redundancy Settings, page 2-12.

• This card requires that the server has CIMC firmware version 1.2(1) or later installed. There is a

heartbeat LED on the top and bottom of the card that indicates when firmware is active.

• To use this card for UCS integration (UCSM mode) with Cisco UCS Manager 2.0(2xx) or later, the

minimum card-firmware and uboot image level is 2.0(2g).

• To use this card for UCS integration (UCSM mode) with Cisco UCS Manager 1.4 or 2.0(1), the

minimum card-firmware and uboot image level is 1.4(1i).

• To connect this card to an upstream Cisco Nexus fabric interconnect (switch), the minimum NXOS

version on the fabric interconnect must be 5.0 or later.

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 3-36

• Resolving Insufficient 16-Bit I/O Space, page 3-37

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 space 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.

Chapter 3 Maintaining the Server

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.

Chapter 3 Maintaining the Server

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.

Installing or Replacing Components

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 the 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.

Replacing an LSI Battery Backup Unit

In the Cisco UCS C250 server, the battery backup unit (BBU) is installed directly onto the LSI controller card.

Note A cable is shipped with the BBU that is used for installing the BBU on a bracket in other server models.

Do not use this cable in the Cisco UCS C250 server; install the BBU directly onto the LSI controller card. Connecting the extra cable causes error messages because the multiple connections are detected as multiple BBUs (an unsupported configuration).

Note LSI recommends that you replace the LSI BBU once per year or after 1,000 recharge cycles, whichever

comes first. Verify whether BBU replacement is required by looking in the CIMC. Log in to CIMC for the server, then click Server—Inventory—Storage—Battery Backup Unit. If the Battery Replacement Required field says, “True,” then you must purchase a replacement BBU and replace it.

Chapter 3 Maintaining the Server

Warning

Statement 1015

To install or replace a battery backup unit (BBU), follow these steps:

Step 1 Remove a BBU:

a. Remove the three screws that secure the BBU to the LSI controller card. b. Lift the BBU straight up to free its connector from the socket on the LSI controller card.

Step 2 Install a BBU:

a. With the battery side up, set the BBU on the front of the LSI controller card.

Align the three screw-holes in the BBU with the three standoffs on the LSI controller card for guidance.

b. Carefully align the J5 connector on the underside of the BBU with the socket on the LSI controller

card and then press downward to fully join the J5 connector with the socket.

c. Install the three screws that secure the BBU to the LSI controller card.

Cisco UCS C250 Server Cabling

The cable connections required for each type of supported controller are as follows:

LSI SAS3081E-R PCIe Card

The required R2XX-PL003-CBL cable kit has two mini-SAS cables. Cable 1 controls drives 1–4 and cable

2 controls drives 5–8.

1. Connect mini-SAS cable 1 from connector SAS1 on the controller to the SAS1 connector on the

backplane.

2. Connect mini-SAS cable 2 from connector SAS2 on the controller to the SAS2 connector on the

backplane.

LSI MegaRAID SAS 9261-8iPCIe Card

The required R2XX-PL003-CBL cable kit has two mini-SAS cables. Cable 1 controls drives 1–4 and cable

2 controls drives 5–8.

1. Connect mini-SAS cable 1 from connector SAS1 on the controller to the SAS1 connector on the

backplane.

2. Connect mini-SAS cable 2 from connector SAS2 on the controller to the SAS2 connector on the

backplane.

How to Determine Which Controller Is in Your Server

If you do not have a record of which option is used in the server, you can disable quiet boot and read the on-screen messages that are displayed during system bootup.

Information about the models of card installed are displayed as part of the verbose boot. You are also prompted to press Ctrl-H to launch configuration utilities for those cards. For servers running CIMC firmware earlier than release 1.2(1), see also

Than Release 1.2(1), page C-4.

Appendix C RAID Controller Considerations

How to Disable Quiet Boot For CIMC Firmware Earlier Than Release 1.2(1)

For CIMC firmware and BIOS release 1.2(1) and later, Quiet Boot has been removed. If you are running CIMC firmware and BIOS earlier than release 1.2(1), you can use the following procedure to disable Quiet Boot.

To disable quiet boot so that the controller information and the prompts for the option ROM-based LSI utilities are displayed during bootup, follow these steps:

Step 1 Boot the server and watch for the F2 prompt during bootup. Step 2 Press F2 when prompted to enter the BIOS Setup utility. Step 3 On the Main page of the BIOS Setup utility, set Quiet Boot to Disabled. This allows non-default

messages, prompts, and POST messages to display during bootup instead of the Cisco logo screen.

Step 4 Press F10 to save your changes and exit the utility. Step 5 Press F10 to save your changes and exit the utility.

How To Launch Option ROM-Based Controller Utilities

To alter the RAID configurations on your hard drives, you can use your host-based utilities that you install on top of your host OS, or you can use the LSI option ROM-based utilities that are installed on the server.

When you boot the server and you have quite boot disabled (see How to Disable Quiet Boot For CIMC

Firmware Earlier Than Release 1.2(1), page C-4), information about your controller is displayed along

with the prompts for the key combination to launch the option ROM-based utilities for your controller.

Watch for the prompt for your controller during verbose boot (Ctrl-H).

Note Cisco has also developed the Cisco Server Configuration Utility for C-Series servers, which can assist

you in setting up some RAID configurations for your drives. This utility is shipped with new servers on CD. You can also download the ISO from Cisco.com. See the user documentation for this utility at the following URL:

Appendix C RAID Controller Considerations

Restoring RAID Configuration After Replacing a RAID Controller

When you replace a RAID controller, the RAID configuration that is stored in the control ler is lost. Use the following procedure to restore your RAID configuration to your new RAID controller.

Step 1 Replace your RAID controller. See Installing a PCIe Card, page 3-33. Step 2 If this was a full chassis swap, replace all drives into the drive bays, in the same order that they were

installed in the old chassis.

Step 3 If Quiet Boot is enabled , disable it in the system BIOS. See How to Disable Quiet Boot For CIMC

Firmware Earlier Than Release 1.2(1), page C-4.

Step 4 Reboot the server and watch for the prompt to press F. Step 5 Press F when you see the following on-screen prompt:

Foreign configuration(s) found on adapter. Press any key to continue or ‘C’ load the configuration utility, or ‘F’ to import foreign configuration(s) and continue.

Step 6 Press any key (other than C) to continue when you see the following on-screen prompt:

All of the disks from your previous configuration are gone. If this is an unexpected message, then please power of your system and check your cables to ensure all disks are present. Press any key to continue, or ‘C’ to load the configuration utility.

Step 7 Watch the subsequent screens for confirmation that your RAID configuration was imported correctly.

• If you see the following message, your configuration was successfully imported. The LSI virtual

drive is also listed among the storage devices.

N Virtual Drive(s) found on host adapter.

• If you see the following message, your configuration was not imported. This can happen if you do

not press F quickly enough when prom pted. In this case, reboo t the server and t ry the impo rt operation again wen you are prompted to press F.

0 Virtual Drive(s) found on host adapter.
