Removing the SAN Volume Controller 2145-8F4 or SAN Volume Controller 2145-8F2 service controller

To remove the service controller, perform the following steps:

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.
Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
Open fan door A ( in Figure 1) of the node.

Press the release latch and then pull the service controller forward and out of the cage assembly.
Note: When you replace a service controller, it is normal to change the worldwide node name (WWNN) of the new service controller to match the one that is being replaced. In this case, you will have two service controllers with the same WWNN. Clearly label the service controller that you are removing and indicate that its WWNN is now a duplicate and that it must not be connected to a SAN before its WWNN is reset.
Remove the retention clip . Make sure to save the retention clip for when you reinstall the node.
