RRP: Power Supply

Use the following procedures to remove or replace a power supply from the rear

of the switch. No tools are required.

Removal

To remove a power supply:

1. Identify the defective power supply from the extinguished green LED at the

switch or failure information at the HAFM appliance Hardware View.

2. Turn off the power switch on the power supply.

3. Disconnect the AC power cord from the power supply.

4. Rotate the power lockout lever to the right to expose the black plastic latch

lever.

5. Pull the latch lever down to the horizontal position.

The power supply will disengage and back out about 1/4 inch when the lever

is horizontal.

6. Use the latch lever to pull the power supply out of the chassis. Support the

power supply as it exits the chassis.

WARNING: To prevent electric shock, do not reach into nonvisible areas of a

switch while the switch is connected to primary facility power.

Replacement

To replace a power supply:

1. Remove the replacement power supply from its shipping container.

2. Inspect the rear of the power supply for bent or broken connector pins. If any

pins are damaged, obtain a new power supply.

3. Ensure that the power switch on the power supply is turned off, the power

lockout lever is rotated to the right, covering the AC connector, and the black

plastic latch lever is completely down in the horizontal position.

4. Insert the power supply into the chassis until it stops.
