Power System Overview
The Cisco NCS 6000 FCC can be configured with either an AC input power system or a DC input power
system. Site power requirements differ, depending on the source voltage used.
For information about power safety requirements, see the
the Cisco Network Convergence System 6000 Series Routers.
Prerequisites
Follow these precautions and recommendations when planning power connections to the FCC:
• Check the power at your site before installation to ensure that you are receiving clean power (free of
• Install proper grounding to avoid damage from lightning and power surges.
Installing the Fabric Card Chassis Ground Cable
The FCC has two safety earth ground connections. You can connect the central office ground system or interior
equipment grounding system to either of these grounding points on the rear side of the FCC. One chassis
ground is located near the top of the FCC and one chassis ground is located at the bottom of the FCC. These
