This chapter describes the power supplies and environmental sensing and reporting in Ultra Enterprise systems. There are differences in the power distribution depending on the enclosure (16-slot or 8-slot).

There are two types of power supplies: a power/cooling module (PCM) and a peripheral power supply (PPS).

Both types of power supplies are hot-pluggable. This feature allows you to physically remove the failed component, despite its being “live,” or being supplied with electrical power. In addition, a new component may be inserted into a running system.
