26 Maintaining and Troubleshooting the Gateway ALR 7300 Server
Replacing the processor
The system is compatible with Intel Pentium
®
II Xeon
™
processors.
You can either upgrade the existing Pentium II Xeon processor or install a
second processor of the same speed as the first processor.
When replacing a processor, order a Pentium II Xeon processor upgrade kit.
The kit includes the Pentium II Xeon processor, a heat sink, and a VRM.
It is critical that a heat sink be installed on each Pentium II Xeon processor.
The Pentium II Xeon processor overheats and fails if it is not cooled
sufficiently. The heat sink provided with the processor on the system
provides all necessary cooling for the processor.
For the latest details on the availability of the upgrade kits, contact one of
the sources listed in the Assistance Resources document.
1.
Turn off the system and disconnect the power cord.
2.
Open the case (“Opening the system” on page 3), observing the static
electricity precautions in “Static electricity precautions” on page 2.
3.
Wearing an anti-static wristband grounded to the system chassis,
remove the lock bar from the processor slot by removing the two
screws that secure it (see Figure 11).
To Replace the Processor
Important!
If the error message
“update table not found for
CPUxx, Stepping xxxx”
displays at boot up, run the
MULOADER utility located
on the disk included with
your processor kit. This
message may occur under
the following conditions:
When a new processor has
been added that does not
include the stepping
information in the table.
When the BIOS is flashed,
it may remove the stepping
information form the table
which will cause the error
message to appear.
