Determining Which Power Supply Failed
To determine which power supply has failed, enter the following command at any CLI command prompt:
FastIron# show chassis
This command displays status information for the power supplies, as well as information for the fans, and
temperature readings for various components in the chassis. The power supplies are numbered in the display.
“Power 1” indicates the power supply installed in power supply slot 1, “power 2” indicates the power supply
installed in slot 2, and so on. Figure 7.11 and Figure 7.12 show the power supply slot numbers.
If the display indicates “Installed (Failed)” for any of the slots, the power supply installed in that particular slot has
failed.

Removing an AC Power Supply
You can order a new AC power supply from Foundry Networks.
The procedures for removing an AC power supply differ depending on the power supply type (replacement or
original). Be sure to refer to the appropriate procedures in this section. For the differences between replacement
and original power supplies, see “About Replacement Power Supplies” on page 2-29.
WARNING:
The power supplies are hot swappable, which means they can be removed and replaced while the
chassis is powered on and running. However, Foundry recommends that you disconnect the power supply from
the wall outlet before removing and replacing the supply. The chassis can be running while a power supply is
being removed and replaced, but the power supply itself should not be connected to a power source. Otherwise,
you could be injured or the power supply or other parts of the device could be damaged.
