Replacing an AC Power Supply
CAUTION:
To avoid electric shock, be sure to set the faulty power supply's ON/OFF switch (I/O) to the OFF
(O) position, and to disconnect the power cord from both the power supply and the wall outlet
before attempting to remove the power supply from the chassis.
To replace a defective AC power supply:
1. If installed, remove the power supply bay grille to gain access to the power supply bay.
2. Set the defective power supply's ON/OFF switch (I/O) located on the front of the supply to the OFF
(O) position.
3. Remove the power cord from the wall outlet.
4. Remove the power cord from the power supply socket.
5. Loosen the spring-loaded screws that secure the power supply to the front of the 8265.
6. Pull the power supply straight out from the chassis, making certain you do not damage the connectors
on the rear of the supply or those on the power switching board.
7. Remove the replacement power supply from its shipping box and set the power supply's ON/OFF (I/O)
switch to the OFF (O) position.
CAUTION:
Be sure to use the same power type (AC) as the removed power supply.
8. Carefully slide the power supply into the selected power supply slot (the same slot from which the
defective supply was removed, or any other available power supply slot).
Figure 22 shows how to insert the power supply.
