Chapter 4 Removing and Replacing FRUs

Removing and Replacing the Power Supply

Step 13 Check the power supply and system status from the system console by entering show power command. For more information on this command, refer to the command reference publication for your switch.

Step 14 If the LEDs or show power command output indicate a power problem or other system problem, see Chapter 5, “Troubleshooting,” for more information.

Removing a DC-Input Power Supply

This section describes how to remove a DC-input power supply.

Required Tools

You will need the following tools to perform this procedure:

A Phillips screwdriver

A 10-mm wrench/socket

Removal Procedure

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.

Statement 1003

Follow these steps to remove a DC-input power supply:

Step 1 Turn off the in-line power switch. (Single input only. The triple-input power supply does not have this switch.)

Step 2 Turn off the main power switch.

Step 3 Verify that power is off to the DC circuit on the power supply you are removing.

Step 4 Loosen the screw on the terminal block cover and remove it from the terminal block (see Figure 4-11or Figure 4-12). The triple-input power supply has two screws on the cover.
