T1600 Power System Description

 

The T1600 Core Router has two redundant, load-sharing power supplies, located at the lower rear of the chassis in slots PEM0 and PEM1 (top to bottom).

The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the T1600 router components, depending on their voltage requirements. For each output voltage that the power supply provides, it has either an active circuit breaker or an active current limiter.

Note

There are no passive fuses in the router that must be replaced.

Each power supply is cooled by its own internal cooling system. Power supplies are hot-removable and hot-insertable.

The T1600 router supports the power supplies in Table 1.

Note

Redundant power supplies must be the same model number during normal operations.
