FRUs must be replaced only by trained service technicians. When replacing the system-board and chassis assembly, you will replace the system board, blade base (chassis), microprocessors, and heat sinks as one assembly. After replacement, you must either update the system with the latest firmware or restore the pre-existing firmware that the customer provides on a diskette or CD image.
Note: See System-board layouts for
more information on the locations of the connectors and LEDs on the
system board.
To replace the system-board and chassis assembly, complete the following steps:
- Read
the Safety topic and the Installation guidelines.
- Is the blade server managed by a management console?
- If the blade server has the Virtual I/O
Server (VIOS) installed or utilizes more than one partition, back
up partition profile data by using one of the following methods:
- If this system is managed by an Hardware Management Console (HMC), back up the partition profile data by using the HMC. See Backing up the partition profile data.
- If this system is managed by an Integrated Virtualization Manager (IVM), back up the partition profile data. Using the IVM command line, enter the bkprofdata command. For more information about the bkprofdata command, see IVM bkprofdata command.
- Does the blade server have Fibre Channel adapters?
- Yes
- Save vfchost map data. Then, continue with the next step.
- No
- Continue with the next step.
- Shut down the operating system, turn off the blade server, and remove the blade server from the BladeCenter® unit. See Removing the blade server from a BladeCenter unit.
- Carefully lay the blade server on a flat, static-protective surface, with the cover side up.
- Open and remove the blade
server
cover. See Removing the blade server cover. Note: If you are servicing the base unit of a PS704 blade server, you must first remove the expansion unit. For more information, see Removing the expansion unit for a PS704 blade server.
- If you are servicing a base unit and not an expansion unit, remove the bezel assembly. See Removing the bezel assembly.
- Remove any of the installed components listed below from
the system board; then, place them on a non-conductive surface or
install them on the new system board and chassis assembly.
- I/O expansion card. See Removing and installing an I/O expansion card.
- Hard disk drives. See Removing a hard-disk drive.
- DIMMs. See Removing a memory module.
- Management card. See Removing the tier 2 management card.
- Battery. See Removing the battery.
- Touch the static-protective package that contains the system-board and chassis assembly to any unpainted metal surface on the BladeCenter unit or any unpainted metal surface on any other grounded rack component; then, remove the assembly from its package.
- Install any of the components listed below that were removed
from the old system-board and chassis assembly.
- I/O expansion card. See Removing and installing an I/O expansion card.
- Hard disk drives. See Installing a hard-disk drive.
- DIMMs. See Installing a memory module.
- Management card. See Installing the tier 2 management card.
- Battery. See Installing the battery.
Note: Install a DIMM filler or a hard drive filler in any location where a DIMM or hard drive is not present to avoid machine damage. - If you are servicing a base unit and not an expansion unit, install the bezel assembly. See Installing the bezel assembly for instructions.
- Install
and close the blade server
cover. See Installing and closing the blade server cover.
Statement 21
CAUTION:Hazardous energy is present when the blade server is connected to the power source. Always replace the blade server cover before installing the blade server. - Write the machine type, model number, and serial number
of the blade server on the repair identification (RID) tag that comes
with the replacement system-board and chassis assembly. This information
is on the identification label that is behind the control-panel door
on the front of the blade server. Important: Completing the information on the RID tag ensures future entitlement for service.
- Place the RID tag on the bottom of the blade server chassis.
- Install the blade server into the BladeCenter unit. See Installing the blade server in a BladeCenter unit.
- Is the blade server managed by a
management console?
- Yes
- Continue with step 18.
- No
- Turn on the blade server and then continue with step 19.
Note: Because you are using a management card that was initialized from your old system board and chassis assembly, the firmware retrieves the vital product data (VPD) from the management card and caches it in blade server memory and you do not see any prompts for data. - If the blade server has VIOS installed
or utilizes more than one partition, restore partition profile data
by using one of the following methods:
- If this system is managed by an HMC, recover the partition profile
data because the blade server is in Recovery state. For instructions,
see Correcting a Recovery
state for a managed system.Note: The blade server is turned on as part of the recovery process.
- If this system is managed by an IVM, turn on the blade server, then restore the partition profile data. Using the IVM command line, enter the rstprofdata command. For more information about the rstprofdata command, see IVM rstprofdata command.

- Does the blade server have Fibre
Channel adapters?
- Yes
- Restore vfchost map data. Then, continue with the next step.
- No
- Continue with the next step.
- Reset the system date and time through the operating system
that you installed.
For additional information, see the documentation for your operating system.
