Replacing the CPU module

About replacing the CPU module

Replacing the CPU module consists of the following procedures:

Location of the CPU module and blank filler module

The CPU module is at the center position on the back of your appliance. A clustered FAS270c has two CPU modules (nodes), with Node A above Node B. On a FAS250 or nonclustered FAS270, a blank filler module is in the top position directly above the bottom CPU module. Both modules use the same cam handle to remove and install the module.

Caution
Both modules must be in place during operation to ensure proper airflow through the appliance.
