The T320 Core Router supports DC power only. The router is equipped with two redundant,
load-sharing DC power supplies (see
the chassis in slots and
PEM0
which has its own circuit breaker, and which requires a dedicated DC power source. The
power supplies connect to the midplane, which distributes the different output voltages
produced by the power supplies to the router components, depending on their voltage
requirements.
When the router is operating normally and both power supplies are switched on,
load-sharing between them occurs automatically. When one power supply fails or is
turned off, the other power supply immediately assumes the entire electrical load for
the system. A single power supply can provide full power for as long as the router is
operational.
Power supplies are hot-removable and hot-insertable. Each power supply is cooled by
its own internal cooling system.
