ac Power Supply Exchange
Note
When replacing a power supply, you must leave enough supplies running at all times to satisfy the
requirements of installed modules. If removal of a defective, but still functioning, power supply will not
cause a power deficit in the 8265, you can remove the faulty supply without losing power to a module
or modules. Before attempting to remove a power supply from the chassis, enter the
show power
budget command to display current power conditions for the 8265.
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 (see
Figure 4-2 on page 4-4).
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).
