Power Board
The power board in a PMF CRU supplies power to the components within that PMF
CRU. In the S7000 PMF CRU, power supplies reside on the power board. In S7400,
S7600, S7800, S7800B, and Sxx000 PMF CRUs, the power board receives DC power
from the power supplies in the power shelf and conditions the power before distributing
it to the other components.
The pair of PMF CRUs within an enclosure also supplies redundant power to the
following devices within that enclosure:
•
Disk drives
•
SCSI terminators
•
SEBs
•
ServerNet adapters
