Removing the Power Supply
This section describes how to remove the power supply. Note the following safety warnings before you
remove the power supply:
Warning Ultimate disposal of this product should be handled according to all national laws and regulations.
Statement 1040
Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Statement 49

Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.
Statement 1
Warning Before working on equipment that is connected to power lines, remove jewelry (including rings,
necklaces, and watches). Metal objects will heat up when connected to power and ground and can
cause serious burns or weld the metal object to the terminals. Statement 43
Caution If the power supply unit was originally fitted with the AS54XM-AC-RPS and during the
power supply unit’s lifecycle is exchanged to the AS54XM-DC-RPS, Cisco IOS will report
that the AS54XM-AC-RPS is still installed.
For this reason, Cisco does not recommend replacing the AC power supply with the DC
power supply, or the DC power supply with the AC power supply.
To remove the power supply, follow these steps:
Step 1 Place the chassis so that the rear panel is facing you.
Step 2 Remove the three mounting screws that secure the power supply to the chassis and set them aside. (See
Figure B-4 .)
