Servicing and Upgrading a CX200-Series DPE2
If the enclosure Fault light is on, examine the other status lights to
determine which FRU(s) is faulty. If a fault light on a FRU remains on,
you should replace that FRU as soon as possible.
When a redundant FRU fails, high availability is compromised until you
replace the faulty FRU.
Handling FRUs
This section describes the precautions that you must take and the
general procedures you must follow when removing, installing, and
storing FRUs.

although removing an active SP will affect operating system access to
