Figure 4-11. Power Supply Removal
To remove a power supply, follow these steps:
1. Turn the locking switch on the power supply to the Off position
(marked by a “0”).
2. Unhook the cable strain relief to free the AC power cable.
3. Disconnect the AC power cable from the power outlet; then disconnect
the other end of the cable from the power supply.
4. Turn the insertion screw counterclockwise to release the power supply.
5. Slide the power supply out of the chassis.
To replace a power supply, perform these steps in reverse order.
WARNING: In a redundant system, you can remove and replace a power
supply without turning off the system. When doing so, be careful not to
touch any of the connectors on the power-supply paralleling board.
CAUTION: To maintain proper airflow and prevent the system from
overheating, each power supply bay must have either a power supply or
a power closeout panel installed.
