Power Cooling Modules

The PCM is an integrated power supply, battery, and cooling fan. There are two types of PCMs:
The 580 W PCM is used in drive enclosures and does not include a battery.
The 764 W PCM is used in node enclosures and includes a replaceable battery.
The PCMs are located at the rear of the storage system, and on the sides of the enclosure. There
are two PCMs per enclosure. The PCMs are numbered 0 and 1 from left to right.

In the HP M6720 Drive Enclosure, the two PCMs are located diagonally from one another. The
