A lighted amber LED on a power supply indicates that a failure was detected. You can also use the ILOM show faulty command at the sc> prompt.

Note - The fans of a failed power supply may still be spinning when the system is powered on. The failed power supply is still okay to remove.

Log in to the ILOM service processor as root.
Refer to the ILOM 3.0 documentation for instructions.

At the ILOM prompt (->), type the stop /SYS/PSn command.
The stop command indicates if it is okay to perform a hot removal of a power supply. This command does not perform any action, but it provides a warning if the power supply should not be removed because the other power supply is not providing power to the server.

For example:
```
-> stop /SYS/PSn
Are you sure you want to remove PSn [y/n]? y
<PSn> is safe to remove.
```
In this command, PSn is the identifier for the power supply you plan to remove, either PS0 or PS1.

Pull the power supply out of the chassis.
Caution - To maintain system cooling and EMI requirements, you must replace the power supply immediately.
