BCM400 redundant power supply
The redundant power supply (RPS) is available as a field replaceable unit (FRU). The redundant
power supply consists of two power supply modules and a power supply chassis. The power
supply modules are interchangeable and can be exchanged one at a time during power-on
conditions. Figure 30 illustrates the redundant power supply chassis and modules. Figure 31
provides details on the redundant power supply connectors.
