7.12.1.1Removing a PSU Module

Warning Do not remove the faulty Power Supply/Cooling module unless you have a replacement unit of the correct type ready for insertion.

If a power supply unit or its fan is faulty, you must replace the whole Power Supply/Cooling module.

As there should always be two power supply units installed, you can continue working while replacing the faulty module.

1Make sure you identify the faulty Power Supply/Cooling module correctly, from the two modules installed,

2Switch off and disconnect the power supply cord.

3Squeeze the two latches on the PSU handle together (Figure 7–2) and open the handle to cam the PSU out of the enclosure (Figure 7–3).

4Grip the handle and withdraw the PSU (Figure 7–4).

7.12.1.2Inserting the Module

1Check for damage, especially to the rear connector on the PSU.

Caution Handle the module carefully and avoid damaging the connector pins. Do not install the module if any pins appear to be bent.
