Installation Precautions and Warnings
Follow these precautions when installing a power supply in the FastIron switch.
WARNING: Before beginning the installation, see the precautions in “Power Precautions” on page 3-3.
CAUTION: Do not install the device in an environment where the operating ambient temperature might exceed
40° C (104° 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 compact 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.
2. Disconnect the power cord from the power supply.
3. If necessary, remove the power supply locking screw located in the center rear of the device.
4. Press inward on the two latches near the edges of the power supply to unlock the supply.
5. Hold the bar on the front panel of the power supply and pull outward. This will disconnect the power supply
from the backplane.
6. Continue to pull the power supply until it is removed from the device.
7. Place the power supply in an anti-static bag for storage.
8. Insert a new supply, or place the cover plate over the empty power supply bay and press the two latches near
the edges of the supply outward to lock the plate into place.
9. If necessary, replace the power supply locking screw.
Installing an AC Power Supply
To install an AC power supply, do the following:
FastIron>show chassis
power supply 1 ok
power supply 2 not present
power supply 1 to 2 from left to right
fan ok
Current temperature : 41.0 C degrees
Warning level : 64 C degrees, shutdown level : 80 C degrees
