Chassis Power System

The Cisco NCS 6008 chassis can be either AC-powered or DC-powered.Each type of power system
supports N+N redundancy for all feeds and power system components. The chassis contains six power
trays of either type. An AC power tray contains up to three AC PMs. A DC power tray contains up to
four DC PMs.
The PMs will load-share across input power feeds. The load is balanced across all input feeds.
Each AC PM requires its own single-phase AC input power feed. If you have 3-phase AC-Delta or
AC-Wye at your equipment, a Cisco NCS 3-Phase AC PDU is required to convert a 3-phase AC input
power feed to three single-phase AC input power feeds.
