IMG 1010 - Connecting to Redundant Power Sources
- Kelli Higdon
A second power source can be added to the chassis for power redundancy. The secondary source serves as backup to the primary source (power supply).
Warnings/Cautions:
Failure to turn power OFF at the redundant power source may result in electrical shock.
Ensure that the wires are pushed into the plug far enough, so that none of the copper is visible.
The DC power module plugs are polarity sensitive. The unit will not operate if the plugs are not wired correctly. See wiring diagram below.
Procedure:
Complete the following steps to connect a redundant power source to the chassis.
Ensure both circuit breakers on the DC power module are set to OFF (O).
Turn power OFF at redundant power source.
Route the RET and -48V wires from the redundant power source to the DC power module plug. Secure the wires to the plug with screws.
The power module plugs are in a small plastic bag included in your shipment.
Insert the plug into the DC power module and secure with screws.
Turn power ON at redundant power source.
Press the required circuit breaker on the DC power module to ON (I).
