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.
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.

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
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
