About this document

This document helps you do the following tasks:

vIdentify a failed power supply unit

vRemove the failed power supply unit and replace it with a new power supply unit

vVerify that the replacement power supply unit is working correctly

Best Practice: Replace a failed power supply unit as soon as possible.

Important: Before you proceed with these instructions, please review the IBM Systems Safety Notices

provided in the IBM Media Terms and Conditions CD that is shipped with the GX7000 Series appliance.

Identifying a failed power supply unit

There are two power supply units in the back of the GX7000 Series appliance. The power supply units

can be hot-swapped, so you can replace a single power supply unit without powering down the GX7000

Series appliance.

Understanding the power supply unit LED status

Each power supply unit contains an LED that indicates whether the unit is working as expected,

generally:

vAn LED that is lit green (solid or blinking) indicates that the unit is working as expected.

vAn LED that is lit amber or is not lit (off) indicates that the unit is not working as expected.

Understanding the fault LED status

There are also fault LEDs on the front panel of the appliance that illuminate in amber when there is a

problem with one of the power supply units:

v: The fault LED for the power supply unit that is located in the top slot of the chassis in the back

of the appliance.

v: The fault LED for the power supply unit that is located in the bottom slot of the chassis in the

back of the appliance.

Note: The fault LEDs on the front panel might vary in appearance depending on which GX7000 Series

appliance you are using.

Determining when to replace a power supply unit

Use the following table to determine the status of the power supply units and whether you must replace

one of the units.

correctly to the appliance

and that the appliance is

connected to a working AC

power source.

connected correctly to the

power supply unit and

to a working AC power

outlet.

vThe power supply unit is

seated correctly in the

Replacing a failed power supply unit

Before you begin

When you are replacing a failed power supply unit, make sure that you do not unplug the power supply

unit that is working as this will disrupt service to the GX7000 Series appliance.

Procedure

Do the following steps to replace a failed power supply unit.

1. Unplug the power cord of the failed power supply unit.

2. Remove the power supply unit.

a. Firmly grip handle A of the failed power supply unit while pressing the orange release latch B

toward handle A, and hold the release latch in this position, as shown in Figure 1.

b. Pull the failed power supply unit from the back of the appliance.

3. When fully removed from the back of the appliance, set aside the failed power supply unit.

Attention: Make sure that the gold connectors at the rear of the power supply unit do not come into

contact with your hands or with the packing material as you unpack the replacement power supply

unit. Avoid damaging the gold connectors against the chassis as you insert the replacement power

supply unit.

4. Unpack the replacement power supply unit.

5. Carefully align the replacement power supply unit, and fully insert the power supply unit into the

chassis until you hear the release latch click in place.

6. Plug in the power cord to the replaced power supply unit.

What to do next

After replacing the power supply unit, you can verify that the new power supply unit is working

correctly.

vThe power supply unit LED on the back of the appliance is green (solid or blinking).

vThe fault LED (for the power supply unit that you just replaced) on the front of the appliance is not lit.
