Removing the standard power supply

If the standard power supply fails, the system will be down. Follow these steps to remove the

power supply.

1Set up the server for maintenance by removing all the cables from the front of the BCM1000,

then disconnect the BCM1000 and the BCM1000e, if there is one, from the ac power

connection.

2Remove the cover from the base unit.

3Attach one end of the grounding strap to your wrist and the other end to a grounded metal

surface.

4Remove the power supply cables from the motherboard, media bays, and hard disk.

5Cut the cable ties that hold the power cables to the BCM1000.

6Remove the power supply bracket screw. Refer to Figure 113.

Figure 113 Removing power supply bracket (single-power supply models)

7Remove the power supply bracket.

Note: If you have an updated system with a piggy-back fan arrangement, the rear fan will

be connected to a power supply cable.
