4 Maintaining Power Supply and Cooling Modules

The array can support two hot-swappable power supply and cooling modules.
The array is capable of operating with one power supply cooling module temporarily, but both power supply
cooling modules are required to maintain long-term cooling and reliability of the array.

About Power Supplies

The PS Series array receives power from two power supplies (PSUs).
The PS4210 array contains two 700-watt PSUs, used in the 2U array. Each 700W power supply contains two
cooling fans.
The cooling fans contained in the power supply unit are not serviceable. If fan failures occur, the entire power
supply unit must be replaced.

Identifying Power Supply Failures

You can identify a power supply and cooling module failure by any or all of the following methods:
• LEDs on the power supply and cooling modules. See
• Messages on the console, in the event log, or in the Group Manager GUI Alarms panel.
• Group Manager GUI and CLI output. The GUI Member Enclosure window or the CLI
member name show enclosure
When viewing the rear of the array, power supply 0 is on the left and power supply 1 is on the right.
