AC Power Systems

The AC input power system provides the necessary power for all chassis components. Site power
requirements differ, depending on the source voltage used.

AC Power Requirements

Each AC-powered chassis contains six AC power trays. The upper three AC power trays are contained
within power shelf 0, and the lower three AC power trays are contained within power shelf 1. Each power
