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.

DC PDU

Facility DC power connects to DC-powered routers though the connector blocks on the DC PDU. (See Figure 1-2 and Figure 1-14.)
