Connecting Power Supply Units
The SCE8000 chassis is shipped with the power supplies (AC or DC) already installed. This section provides information for
grounding the SCE8000 platform and connecting the AC or DC power supply units.
Connecting the Chassis Ground
If this equipment is installed in a U.S. or European Central Office, you must connect the system ground on both AC
Note
and DC-powered systems to an earth ground.
Note
For DC-powered systems, the system ground is also the power supply ground. The DC ground must be installed with
a permanent connection to an earth ground according to NEC guidelines.
When you use the PWR-2700-DC/4 power supply in the Cisco SCE8000 chassis, additional grounding requirements
Note
exist.
Two threaded M4 holes are provided on the chassis frame to attach the ground cable.
