Monitoring power supplies
A member has two or three power supplies. Most PS Series arrays use power supplies that have integrated cooling
modules.
A member can survive one power supply failure. Replace failed power
supplies as soon as possible.
For proper cooling, do not remove a power supply until you have a replacement.
For informat
ion about replacing a power supply
, see the Hardware Maintenance manual for your array model or
contact your PS Series support provider.
The Power Supplies panel shows the status of the power supplies. The n
umber and type of hardware components
shown depends on your array model.
Table 15-14 shows power supply status and possible solutions. The first column lists the status values
, the second
column provides descriptions, and the third column provides solutions.

failed Power supply failure. See your PS Series support provider for information
about replacing the power
supply.
Monitoring cooling and fans
A member has two or three cooling modules and multiple fans. Most PS Series arrays use power supplies that have
integrated cooling modules.
Periodically, feel the room temperature where the hardware is
located and make sure that the room is sufficiently
cool and ventilated. Also make sure the fan trays and cooling modules have no red LEDs, and monitor the member
temperature.
A member can survive one cooling module failure. Re
place failed cooling modules as soon as possible.
The Cooling Fans panel shows the status of the fans on the cooling modules. Table 15-15 shows the cooling fan
status. These status values apply to array models with combination
power supply and cooling modules. The first
column lists the status values, the second column provides descriptions, and the third provides solutions.
