Servicing Power Supplies (CRU)

The redundant power supplies on the controller support concurrent maintenance, which enables you to remove and replace a power supply without shutting down the controller, provided that the other power supply is online and working.

The controller supports model A256 (600 watt) power supplies. The A256 power supply unit (PSU) provides conversion from the AC lines to the system, accepting ranges from 100-240 volts AC (VAC). These PSUs are designed to be hot-swappable, and will provide fully redundant ”1+1” power, allowing the system to suffer the loss of a PSU or an AC feed with no loss to system availability.

The following indicators (LEDs) are lit when a power supply fault is detected:

  • Front and rear Service Required LEDs

  • Amber Service Required LED on the faulty power supply

  • Rear Power Supply Fault LED located on the controller front panel (see Front Panel Controls and Indicators)

If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper airflow in the controller.
