Chapter 18 Replacing a power supply 209

Setting up the base unit

This section describes the steps for replacing a standard power supply with a redundant power supply. After the redundant power supply is installed, insert the two power supply modules. Redundant power supply modules can be changed while the system is running, as long as one of the modules remains active.

Note: When you upgrade to a redundant power supply, you must also put in a redundant fan. Refer to “Adding or replacing a cooling fan” on page 197.

1If you still have access to the Unified Manager, shut down the system using the Shutdown command. For details refer to “Shutting down the system software” on page 168. Otherwise, skip to step 2.

2Set up the BCM1000 for maintenance, as described in “Shutting down the system hardware” on page 169.

3Disconnect the power supply from the internal connections.

4Cut the cable ties that hold the power cables to the base unit.

5Remove the standard power supply and set aside.

Refer to “Removing the standard power supply” on page 206.

6Remove the jumper from the connectors on the System Status Module. Refer to the following diagram to locate the SSM board.

The diagram below notes the location of the connectors for the redundant power supply and for the redundant fan.
