Chapter 4 Removing and Replacing FRUs

Removing and Replacing the Chassis Fan Assembly

Caution In a system with multiple power supplies or a single triple-input power supply, connect each power supply to a separate DC power source. In the event of a power source failure, if the second source is still available, it can maintain maximum overcurrent protection for each power connection.

Step 8 Verify power supply operation by checking the power supply’s front-panel LEDs. You should see the following:

The LED labeled INPUT OK is green.

The LED labeled OUTPUT FAIL is not lit.

Step 9 Check the power supply and system status from the system console by entering the show power command. For more information on the commands, refer to the command reference publication for your switch and software.

Step 10 If the LEDs or the show power command (Cisco IOS) output indicate a power problem or other system problem, see Chapter 5, “Troubleshooting,” for more information.

Removing and Replacing the Chassis Fan Assembly

This section describes how to remove and install the chassis fan assembly for the Catalyst 4500 E-series switches. See Figure 4-17for the Catalyst 4506-E system fan assembly, other fan assemblies attach in a very similar way.

Required Tools

You will need a Phillips screwdriver for the following two procedures.

Removing the Fan Assembly

Warning When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Statement 258

Caution Never operate the system for an extended period if the fan assembly is removed or if it is not functioning properly. An over-temperature condition can cause severe equipment damage.

Follow these steps to remove the existing chassis fan assembly:

Step 1 Loosen the two captive installation screws on the fan assembly by turning them counterclockwise.
