Replacing a Power Supply
You can replace a power supply while the FastIron chassis is powered on and running. The power supplies are
located in slots at the rear of the FastIron chassis.
This section provides information about the following topics:
•
Installation precautions and warnings
•
Determining which power supply has failed, if necessary.
•
Replacing an power supply.
WARNING:
Power supplies are hot swappable. However, Foundry Networks recommends that you disconnect
the power supply from AC power before installing or removing the supply. The device can be running while a
power supply is being installed or removed, 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.
Installation Precautions and Warnings
Follow these precautions when installing a power supply in the FastIron chassis.
WARNING:
Before beginning the installation, see the precautions in “Power Precautions” on page 3-4.
CAUTION:
Do not install the device in an environment where the operating ambient temperature might exceed
40
o
C (104
o
F).
CAUTION:
Never leave tools inside the chassis.
Determining Which Power Supply Failed
If you are replacing a power supply that has failed and you are not sure which supply has failed, enter the following
command at any CLI command prompt:
This command displays status information for the power supplies and the fans. The power supplies are numbered
from left to right. These numbers assume you are facing the front of the device, not the rear.
If the display indicates “Installed (Failed)” for any of the slots, the power supply installed in that particular slot has
failed.
AC Power Supplies
Use the following procedures for AC power supplies in FastIron stackable devices. See “Power Supplies” on
page 2-17 for a list of which power supplies are supported in which devices, and for illustrations showing power
supply placement in the Foundry devices.
Removing an AC Power Supply
1.
Unplug the power supply from the power source.
