Power Supply and Cooling Module Status
You can identify a failure on a power supply and cooling module by:
• LEDs. The power supply and cooling module hardware status LED is orange or flashing orange. In addition,
an LED on a power supply and cooling module is orange. See Power Supply and Cooling Module LEDs on
page 4-1.
• Messages. A message on the LCD panel (located behind the bezel), on the console, in the event log, or in the
Group Manager GUI Alarms panel describes a power supply and cooling module failure.
• Group Manager GUI and CLI output. The Member Enclosure window or the
member select show
enclosure
command output shows a power supply and cooling module failure.
When facing the rear of the array, power supply and cooling modules are numbered 0, 1, and 2 from left to right.
See Figure 1-9.
Array Behavior When a Power Supply Fails
If one power supply and cooling module fails, the array will continue to operate as long as two modules are
functioning and connected to power. Otherwise, the array will shut down automatically.
If a power supply and cooling module fails, contact your PS Series support provider for a replacement.
