Chapter 18 Replacing a power supply 209

Installation and Maintenance Guide

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.

1 If 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.

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

on page 169.

3 Disconnect the power supply from the internal connections.

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

5 Remove the standard power supply and set aside.

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

6 Remove 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.

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.
