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. 
Standard supply, BCM1000e:

Figure 122   BCM1000e, standard power supply interior connections
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, 
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 
. Note 
that the version 2.0 cabinets only have one set of fan perforations, as shown in
