System Ground Connection
This section describes how to connect a system (earth) ground to the Cisco 7600 series router.
Note You must connect the system ground on both AC- and DC-powered systems to an earth ground if Foreign
Exchange Station (FXS) modules are installed or if this equipment is installed in a US or European
Central Office
Note For the Cisco 7603 router, Cisco 7604 router, Cisco 7606 router, and Cisco 7606-S 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.
