• Replacing a power supply
WARNIN G: 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 FGS chassis.
WARNIN G: Before beginning the installation, see the precautions in “Power Supply Precautions” on page3-4.
CAUTION: Do not install the device in an environment where the operating ambient temperature might exceed
40o C (104o 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 FGS devices.
WARNIN G: Before beginning the installation, see the precautions in “Power Supply Precautions” on page3-4.
You will need a #2 Phillips-head screwdriver to perform these procedures.
