Power Connection Guidelines

You can configure the chassis with either an AC input or DC input power subsystem, so the site power
source requirements differ depending on the power subsystem in your chassis. Ensure all power
connection wiring conforms to the rules and regulations in the National Electrical Code (NEC) as well
as local codes.
Each power tray includes 4 power modules each. The chassis has two power trays for redundancies (each
tray can provide the full power to the chassis). The power tray provides electrical connections to the
chassis backplane. Each power module can be individually plugged in or out from the tray.
Each Cisco NCS 4016 chassis is powered by only one type of input: AC or DC. A hybrid (AC+DC) power
