Installing Microprocessors
Installing or Replacing a Microprocessor
This section gives the procedure for installing microprocessors. If you want to
remove a microprocessor, reverse the order of the following steps.
Before you begin:
Read “Electrical Safety” on page 41 and “Handling Static-Sensitive Devices”
on page 42.
Thoroughly review the documentation that comes with the microprocessor,
so that you can determine whether you need to update the server BIOS.
The “ServerGuide and Netfinity Manager Information” section of this
Server
Library
includes IBM Update Connector, which keeps your BIOS and device
drivers current. You can also obtain the latest level of BIOS for your server
through the World Wide Web and the IBM Personal Computer Company
Bulletin Board System (BBS). See the “Getting Help Information” section of
this
Server Library
for the appropriate World Wide Web addresses and
bulletin board telephone numbers.
For a list of supported operating systems, see
http://www.pc.ibm.com/compat/ on the World Wide Web.
Notes:
1. If you have not already done so, go to http://www.pc.ibm.com/support/ on the
World Wide Web and download the appropriate flash update program. Review
the applicable README files, and use this information to create a
Flash Utility
Diskette
. Perform the POST/BIOS (flash) update procedure.
2. The microprocessor in your server comes with an attached heat sink. The
microprocessor plugs into the microprocessor socket on the system board and
is stabilized with a plastic bracket attached to the system board.
3. If you replace the microprocessor with one that has a different speed, you must
change the switch settings on the system board. To locate the switches, see
“System Board Connectors” on page 169. For information about the
appropriate switch settings, see Table 17 on page 170, or see the label inside
the server cover.
Attention:
If you select a setting for the frequency switch that is greater than the actual
frequency of the microprocessor, you might damage the microprocessor.
To install a microprocessor:
1. If you have not done so, remove the server cover. See “Preparing to Install
Options” on page 43.
2. If you are installing an additional microprocessor, remove the terminator card
from the secondary microprocessor connector. Otherwise, go to step 3 on
page 68.
a. Spread apart the posts of the secondary microprocessor connector bracket
until the top of the terminator card is past the restraining latches.
b. Lift the terminator card out of the connector.
