Owners Manual

Before removing the PCM, disconnect the power from the PCM by either the mains switch (where present) or by physically
removing the power source in order to ensure your system has warning of imminent power shutdown. Ensure that you correctly
identify the faulty PCM before beginning the step procedure.
1. Stop all I/O from hosts to the enclosure. See Shutting down attached hosts on page 45.
NOTE: This step is not required for hot-swapping. However, it is required when replacing both PCMs at once.
2. Use management software to shut down any other system components necessary.
NOTE: This step is not required for hot-swapping. However, it is required when replacing both PCMs at once.
3. Switch off the faulty PCM, and disconnect the power supply cable.
4. If replacing a single PCM using hot-swap, proceed to step 6.
5. If replacing both PCMs, verify that the enclosure was shut down using management interfaces, and that the enclosure is
powered off.
6. Verify that the power cable is disconnected.
7. Grasp the latch and the side of the PCM handle between thumb and forefinger, squeeze together and open the handle to
cam the PCM out of the enclosure as shown in the following figure.

8. Grip the handle and withdraw the PCM, taking care to support the base of the module with both hands as you remove it
from the enclosure as shown in the following figure.

NOTE:
The remove PCM illustrations show a chassis configured as a 4-port FC/iSCSI controller enclosure. The
procedure applies to all 2U controller enclosures and expansion enclosures.
