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. See "Power Supply LEDs" on page 33 for details. • 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 select show enclosure command shows a power supply and cooling module failure. Note: When viewing the rear of the array, power supply 0 is on the right, and power supply 1 is on the left. Power Supply LEDs The power supplies and cooling modules have LEDs that indicate their status. Figure 23 illustrates the power supply LEDs. Table 7 describes these LEDs. 33

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.
See "Power Supply LEDs" on page 33
for details.
•
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 select
show enclosure
command shows a power supply and cooling module failure.
Note:
When viewing the rear of the array, power supply 0 is on the right, and power supply 1 is on the left.
Power Supply LEDs
The
power supplies and cooling modules have LEDs that indicate their status.
Figure 23
illustrates the power supply LEDs.
Table 7
describes these LEDs.
