CEC Power Supplies
The CEC drawer has two power supplies. You can replace each power supply separately. The removal
and replacement procedures are the same for each power supply.
Each CEC power supply is hot-pluggable. If only one needs to be removed, you do not have to power off
the system.

1. Carefully remove the end of the ac cord on the CEC power supply you want to replace. Do not remove
both ac cords, as power will be lost to the CEC, forcing the system to power off.
2. Remove the screw keeping the latch handle in place, as shown in (1) above.
3. After the latch handle swings freely, position the latch handle (2) so that it is perpendicular to the rear
of the CEC drawer.
4. Pull on the ring attached to the power supply (3) and the latch handle (maintaining its perpendicular
position) to move the power supply away from the CEC drawer.
5. Remove the power supply.
Replacement
Replace in reverse order.
