Removing the microprocessor 2 expansion board

Use this information to remove the microprocessor 2 expansion board.

1. Carefully turn the server on its side so that it is lying flat, with the cover facing up.
   Attention

   Do not allow the server to fall over.
2. Unlock and remove the left-side cover (see Removing the left-side cover).
3. Remove the air baffle (see Removing the air baffle).
4. Remove the fan cage assembly (see Removing the fan cage assembly).
5. Note where the cables are connected to the microprocessor 2 expansion board; then, disconnect them.
   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). 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.
6. Remove any of the following components that are installed on the microprocessor 2 expansion board and put them in a safe, static-protective place:

   • Adapters (see Removing an adapter)

   • DIMMs (see Removing a memory module)

   • Microprocessors and heat sinks (see Removing a microprocessor and heat sink)

     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.
7. Loosen the two thumb screws on the release lever and rotate the lever toward the back of the chassis till the stop point. The microprocessor 2 expansion board will lift up slightly when the release lever is fully open.

8. Grasp the release lever and the handle and carefully lift the microprocessor 2 expansion board out of the server.
