BCM400 redundant power supply

The BCM400 redundant power supply (RPS) is available as a field replaceable unit (FRU) or as part of the BCM400 RFO. The redundant power supply consists of two power supply modules and a power supply unit (see Figure 39 and Figure 40). The power supply modules are interchangeable and can be exchanged one at a time during power-on conditions.
