Operating power requirements
Introduction
This section contains:
power consumption data for both circuit packs and full modules
guidelines and methods to help you determine total system power
requirements, for both AC and DC systems
Circuit
power consumption
The power consumption of all currently-supported peripheral equipment
circuit cards is given in Tables 12 and 13.
circuit cards is given in Tables 12 and 13.
All of the power data is stated in Watts for simplicity, with conversion
or DC current occurring only at the last step in the calculation.

In addition, all
of the stated numbers have
taken the average efficiency of the Module
power converters into account.
The traffic assumptions used in these figures are 25% active (9 CCS) for
digital and analog lines, and 100% active (36 CCS) for trunks. Note that the
power consumption of digital line cards does not vary greatly with traffic, as it
may with analog line cards.
