Attention: Disengage all latches, release tabs or locks on cable connectors
when you disconnect all cables from the system board (see "Internal Cable
Routing and Connectors" on page 47 for more information). Failing to release
them before removing the cables will damage the cable sockets on the
microprocessor 2 expansion board. The cable sockets on the microprocessor 2
expansion board are fragile. Any damage to the cable sockets may require
replacing the microprocessor 2 expansion board.
8. Remove any of the following components that are installed on the
microprocessor 2 expansion board and put them in a safe, static-protective
place:
a. Adapters (see "Removing an adapter" on page 358)
b. DIMMs (see "Removing a memory module" on page 403)
c. Microprocessors and heat sinks (see "Removing a microprocessor and heat
sink" on page 416)
Attention: Remove the socket cover from the microprocessor socket on
the new microprocessor 2 expansion board and place it on the
microprocessor socket of the microprocessor 2 expansion board you are
removing.
9. Make sure the microprocessor 2 expansion board release levers are in the open
position.
10. Grasp the release lever and the handle and carefully lift the microprocessor 2
expansion board out of the server.
