DC Power Subsystem

The DC power subsystem consists of the following system components:

DC PDU (one)

DC-input PEMs (one for nonredundant operation; two for redundant
operation)

Caution

To ensure that the chassis configuration complies with the required power
budgets, use the on-line power calculator. Failure to properly verify the
configuration may result in an unpredictable state if one of the power units fails.
Contact your local sales representative for assistance.
