Replacing a power supply in an BCM1000e

The power supply in the BCM1000e is exactly the same type of power supply as that in the BCM1000. The only difference is that 2.5 version BCM1000es come with either a standard power supply or redundant power supply. In this case the standard power supply cannot be updated to a redundant power supply. You must upgrade the entire unit.

Note: Version 2.0 conversion

If you still have a version 2.0 BCM1000e, which is larger than the 2.5 versions, you can upgrade to a redundant power supply. To perform this upgrade, follow the instructions for updating the BCM1000 power supply, “Upgrading to a redundant power supply” on page 208.

In this configuration, the redundant fan would be installed as a piggy-back unit. The plug for the redundant fan plugs in beside the first fan. Refer to Figure 123 on page 215. Note that the version 2.0 cabinets only have one set of fan perforations, as shown in Figure 122.

To replace a standard or redundant power supply in a version 2.5 BCM1000e unit, you can follow the instructions given in the sections noted below.
