Removing the SAN Volume Controller 2145-8A4 microprocessor

Use this information to remove the SAN Volume Controller 2145-8A4 microprocessor.

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 cable-retention bracket and disconnect the power cable from the node. See Removing the cable-retention bracket.
   
3. Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
   
4. Remove the top cover. See Removing the top cover.
   
5. Remove the air baffle ( in Figure 1). Grasp the air baffle by the leftmost and rightmost rear corners and lift it up out of the node.

6. Open the heat-exchanger-assembly release latch ( in Figure 1) to the fully open position.
7. Lift the side of the heat-exchanger assembly ( in Figure 1) that is closer to the middle of the node, slide it toward the middle of the node slightly, and lift the entire assembly out of the node.
8. Open the microprocessor release latch to the fully open position.

9. Open the microprocessor bracket frame.
   Note: Handle the microprocessor carefully. Dropping the microprocessor during removal can damage the contacts. Also, contaminants on the microprocessor contacts, such as oil from your skin, can cause connection failures between the contacts and the socket.
10. Remove the microprocessor:
    1. Carefully lift the microprocessor straight up and out of the socket, without touching the microprocessor contacts.
    2. Place the microprocessor on a static-protective surface.
