Once the power switches have been turned off, remove the power cables that connect
the subsystem to the main power. The power connector is found on the left side of each
power supply module.
Remove the retention screw: After the power cable has been removed from the power
connector, remove the retention screw at the upper right side of the PSU rear-end panel.
The screw is located below the extraction lever, beside the LED indicator, and can be hid-
den from sight.
Pull the extraction handle downward: Push the extraction lever at the back of the PSU
module downwards. This will dislodge the PSU module from the subsystem. Once dis-
lodged, gently pull the PSU module out of the subsystem.
When a PSU is pulled out of the chassis, the fan module beneath the PSU is removed
from the chassis at the same time.
Do not remove the PSU module unless a replacement is readily available. Removing a PSU
without a replacement will cause severe disruptions to the internal airflow and the sub-
system will overheat, possibly causing irreparable damage to some of the subsystem
components.
It is recommended that the replacement procedure is completed in less than five (5) min-
utes to prevent the subsystem from overheating.
Remove the cooling module: To do this, push the clips on either side of the module rear
panel together. Then gently pull the cooling module out of the lower level of the PSU
bracket. (See Figure 6.5)
