1-2 Replacing the Server Module Board

Before You Begin
Schedule system maintenance time with the customer and remind them that they may
want to back up all files on the hard drives of the affected server modules.
The customer may have mirroring from server module to server module or have a server
module communicating with other server modules. Explain that if you bring a server
module down for maintenance, errors may occur. This allows the customer to take the
necessary steps to deconfigure their system before you begin maintenance.
NOTE: Perform the upgrade on one server module at a time. Do not proceed to
another server module until you have completed the upgrade on the current module.
Determine the server module’s hard-drive configuration.
• If you do not know the configuration or if the server module has two hard drives and
you do not know whether the mirroring function is enabled, see "Verifying the Hard-
Drive Mirroring Mode."
• If the server module has only one hard drive, see "Replacing the Server Module Board."
Turning Off the Server Module
1Select the server module to be replaced.
2Ensure that all applications are closed.
3Shut down the operating system and turn off the server module by pressing the power
button on the front of the server module. See Figure 1-1.
4Ensure that you have access to a keyboard and monitor (KVM, crash cart, or console
redirection).

1Ensure that the server module is turned on. See Figure 1-1.
2Monitor the POST progress.
When the POST reaches the PERC 4/im, either one or two SCSI drives are listed with
their IDs (nonmirrored mode) or one SCSI drive is listed as a virtual disk (mirrored
mode).
The following is an example of the display if there are two drives installed in
nonmirrored mode. If this display is seen during POST, proceed to "Turning Off the
Server Module" and then "Replacing the Server Module Board."
NOTE: Only one drive is listed if only one drive is installed in the server module.

Replacing the Server Module Board
The following procedures are required to replace the server module board. You must follow
the procedures in the order given.
Removing the Server Module
CAUTION: See your System Information Guide for complete information about
safety precautions, working inside the computer, and protecting against
electrostatic discharge.
1Ensure that the server module's power is off.
The blinking green power-on indicator shows that power is available to the system. If
the power-on indicator is solid green, press the module's power button to turn off the
module. See Figure 1-1.
2Using a #2 Phillips screwdriver, loosen the captive screw that secures the server
module's ejector handle to the front of the server module. See Figure 1-2.
3Grasp the server module's handle and rotate the handle down to eject the server
module from the chassis. See Figure 1-2.
4Grasp the server module and slide it out of the chassis. See Figure 1-2.
