Installing Power Components
This chapter provides instructions on how to install power components in the chassis. It also covers information
regarding connecting and disconnecting power and powering on the chassis.
The chassis ships with power trays and power modules installed.
Unless otherwise specified, “chassis” refers to both Cisco NCS 4016 chassis and Cisco NCS 4009 chassis.

Power Connection Guidelines
You can configure the AC chassis with an AC input and the DC chassis with a DC input power subsystem.
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 chassis is powered by only one type of input: AC or DC. A hybrid (AC+DC) power configuration is not
supported.
Caution
Proper grounding is necessary to avoid damage from lightning and power surges. See the
NEBS Supplemental
Unit Bonding and Grounding Guidelines, on page 56
for grounding requirements.
