Changing a power supply
The 8400/8800 series platforms have removable power supplies. You can
change or replace the power supply in the event of a power supply failure.
Replacing the power supply
You do not need special tools to replace the power supply. We recommend
that you perform the power supply replacement on the standby unit in a
redundant system after halting it and powering the system off. After you
install the power supply in the standby system, force the active system to fail
over and install the power supply replacement in the other unit of the
redundant system.

navigate to the System menu.

After you halt and power off the system, you can replace power supply.

standby mode.
