Dual DC Feed
The dual feed IDU supports two DC inputs for power redundancy. Each input
can be connected to a separate power source. The lower input is numbered 1,
and the upper is numbered 2.
Each input can receive voltage in the range of -40.5Vto -60V.
Each power input has a dedicated LED on the front panel which indicates if
that input is receiving adequate power. This means that the LED will be off
when the input voltage is below -40.5V (absolute value).
In addition, the IDU raises an alarm when the power input is below the
minimal level (one alarm per power input). You can mask this alarm using the
CLI. This option can be used if you choose to connect only one power input
and do not want a permanent alarm in the system.
The power input connectors have built-in screws. Appropriate DC cables
should be used, and the screws should be fastened.
