Removing a Microprocessor
Removing a Microprocessor
Your server comes with two processor boards. Some models come
with one microprocessor on each processor board. Other models
come with one microprocessor on one processor board. Your server
supports a maximum of four microprocessors. The system board
contains two processor-board connectors: one is primary; the other
is secondary. You must maintain a processor board in each
connector.

The two smaller illustrations on the right show the two
microprocessor sockets on the processor board. The top right
illustration shows a microprocessor in the bottom (shaded) socket.
The bottom right illustration shows a microprocessor in both sockets
(shaded areas).
Notes:
1. One common reason for removing a microprocessor is to install
an upgrade (faster) device. A faster microprocessor generates
more heat, and thus requires a larger heat sink. Do not attempt
to reuse an existing heat sink. Always install the heat sink
provided in your IBM Processor Upgrade package.
