Removing the Power Supply
Before working on a system that has an on/off switch, turn OFF the power and unplug the
Warning
power cord. To see translations of the warnings that appear in this publication, refer to
the Regulatory Compliance and Safety Information document that accompanied this
device.
Before working on equipment that is connected to power lines, remove jewelry
Warning
(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. To see translations of the warnings that appear in this publication, refer to the
Regulatory Compliance and Safety Information document that accompanied this device.
If the power supply unit was originally fitted with the AS54XM-AC-RPS and during the
Caution
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:
Place the chassis so that the rear panel is facing you.
Step 1
Remove the three mounting screws that secure the power supply to the chassis and set them aside. (See
