Power Supply/Cooling Modules
Two power supply/cooling modules (PSUs), which are mounted in the rear of the
D-brick2, supply redundant cooling and power to the enclosure. Voltage operating
ranges are nominally 115 V or 230 VAC, and are selected automatically. The supplies
should be plugged into your SGI rack’s power distribution strip (PDS). Four LEDs
located on the rear panel of the PSU/cooling module indicate the status of the power
supply and the fans (see Figure 11-5).
Note:
If a power supply fails, do not remove it from the enclosure until you have a
replacement power supply. The cooling fans in the supply will continue to operate.
Caution:
You must install a new PSU/cooling module within 10 minutes after removing
a faulty one. Otherwise, thermal overload of the D-brick2 can result.
