Power management

There are two hot-pluggable AC power supplies located in the rear of
the 8550 WSG that provide connections for redundant power feeds.
The redundant power supplies have independent power cords.

Cooling

Cooling is provided by interior fans. The fans are paired in a redundant
configuration. The speed of the fans is automatically controlled and
varies according to the measured temperatures within the 8550 WSG.
The 8550 WSG also contains a number of sensors that continuously
monitor the interior temperature of the chassis. The temperature
measurements are used to provide information to the fans and thereby
allow for the automatic adjustment of fan speeds and the detection of
failing and failed fans.
