Replacing a power supply
BCM1000s and BCM1000es can have standard or redundant power supplies.
This chapter describes:
• how to replace a standard power supply
• how to upgrade from a standard power supply to a redundant power supply (BCM1000, 2.0 or
2.5 hardware, or BCM1000e, 2.0 hardware.)
• how to replace the power supply module in a redundant power supply system
Replacing a standard power supply
If the BCM1000 or BCM1000e has a standard power supply that fails, then all activity on the
system ceases.
Figure 129 provides an overview of the process for replacing a standard power
supply.
