The DC power distribution panel includes two DC terminal blocks
for connecting to redundant
battery) and return branch circuits. An equipment power switch
with a resettable circuit breaker provides a local control point for
equipment power.
Input power circuits are wired so that the power supplies provide
redundancy even when power supply A or B fails. The Power
Distribution Unit (PDU) provides power from input power A to
power supplies 1 and 2; input power B supplies power to power
supplies 2 and 3. Thus, if either input power source fails, two
power supplies are still functioning to retain power supply
redundancy. Even if one power supply fails, the system may still
perform under this stressed environment until the power supply
and/or input power are restored.
