216NG63A Ports and indicators on the DC power unit

Each cabinet contains two 216NG63A DC power units. Each power supply unit provides power for the entire cabinet.

Connect DC power supply

A cabinet powered by 216NG63A DC power supply contains two DC power units (Psus). Each unit must be connected to a suitable -48V DC power supply. To provide redundancy in the event of a power circuit failure, connect the two Psus to different DC power supplies.

Dc power replaceable component

The DC power supply model has two replaceable parts.
