4 Maintaining Power Supply and Cooling Modules
The array can support two hot-swappable power supply and cooling modules.
The array can operate only temporarily with one module, but both modules must be present for long-term cooling
of the array.
About Power Supplies
The PS Series array receives power from two power supplies (PSUs).
Each PSU has a 700W power supply. Each power supply has two cooling fans.
The fans that keep the array cool are integrated into the power supply modules and cannot be replaced
separately. If a fan fails, you must replace the entire power supply module.
Identifying Power Supply Failures
You can identify a power supply and cooling module failure by any or all of the following:
•
LEDs on the power supply and cooling modules.
•
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
command shows a power supply and cooling module failure.

When viewing the rear of the array, power supply 0 is on the right, and power supply 1 is on the left.
Note:
Power Supply LEDs
The power supplies and cooling modules have LEDs that indicate their status.
