Removal
1. If the system is not partitioned, shut down the operating system and put the
OCP switch in the Off position. Skip step 2.
2. If the system is partitioned and the blower in one of the drawers needs
replacing, neither an operating system nor the SRM should be running.
Power off the partition off using the SCM power off -par x command. Put
the OCP switch in the Secure position. Open the back door of the cabinet.
Note, only hard partitions can be powered off. Therefore, if soft partitions are
used, all soft partitions must be shut down and the hard partition in which
they run must be powered off.
3. Unplug the blower.
4. Remove the seven Phillips head screws holding the blower to the drawer.
5. Remove the blower.
Replacement
Reverse the removal procedure.
Be sure to leave the OCP switch in its original position.
Verification
Power up the system.
