Removing the SAN Volume Controller 2145-8G4 microprocessor

Use this information to remove the SAN Volume Controller 2145-8G4 microprocessor and heat sink.

To correctly perform this task, you must have alcohol wipes and thermal grease available. If you do not already have them, order these separately.
Attention:
  • Do not allow the thermal grease on the microprocessor and heat sink to come in contact with anything. Contact with any surface can compromise the thermal grease and the microprocessor socket.
  • Use great care when handling microprocessors. Dropping the microprocessor during installation or removal can damage the contacts.
  • Do not touch the microprocessor contacts; handle the microprocessor by the edges only. Contaminants on the microprocessor contacts, such as oil from your skin, can cause connection failures between the contacts and the socket.
To remove a microprocessor and heat sink, complete the following steps:
  1. Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering off a SAN Volume Controller node for more information.
  2. Remove the top cover. See Removing the top cover.
  3. Remove the heat sink (reference key one in Figure 1). Loosen two captive screws on alternate sides of the heat sink fully before loosening the other two captive screws. (This helps to break the bond between the heat sink and the microprocessor.) After the captive screws are loosened, remove the heat sink.

  5. Open the microprocessor bracket frame (reference key two in Figure 2).
  6. Carefully remove the microprocessor from the socket. Be careful to only touch the edges of the microprocessor.
