Sufficient to supply the rated input current. Local codes apply.

Redundancy DC power modules operate in N+1 redundancy mode. Up to sixteen

DC power modules are supported. The number of DC power modules

needed depends on the configuration of the chassis (e.g. number of line

cards, RPs, and FC cards installed). Use the Cisco Power Calculator

(Cisco.com account required) at http://tools.cisco.com/cpc/launch.jsp

to calculate how many DC power modules are needed.
