Removing and Replacing Enclosure Components
Removing an APC
Before you remove an APC, ensure that you have a replacement
module ready for immediate installation so that proper cooling and
airflow are maintained. Failed APCs must be replaced within five
minutes, or the system does an orderly shut-down.
To remove an APC from the Storage Enclosure:
1
Power off the failed APC module and remove the power cable.
If the enclosure is powered on, the fans in both APC modules
switch to high speed. The cooling fans in the failed APC are
now running on power supplied by the other APC module.
2
Using a Phillips-head screwdriver, loosen the two screws on the
APC module that hold the handles in place.
3
Gently push down on the handles to disengage the APC
module from the enclosure.
4
Using the handles, gently slide the APC out of the enclosure, as
shown in
Figure 4-2
