Note You must connect both the system ground connection and the power supply ground connection to an earth ground. The system ground connection is required if Foreign Exchange Station (FXS) modules are installed or if this equipment is installed in a US or European Central Office.

Two threaded M4 holes are provided on the chassis frame to attach the ground cable. (See Figure 3-6.)

Note If FXS modules are installed or if this equipment is installed in a US or European Central Office, you must use the system (earth) ground on both AC- and DC-powered systems.

•One grounding wire

The grounding wire should be sized according to local and national installation requirements. The length of the grounding wires depends on the proximity of the Cisco 7609 Internet Router to proper grounding facilities.
