This section describes how to connect a system (earth) ground to the Cisco 7609
Internet Router.
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.)
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.
To connect the system ground, you need the following tools and materials:
Materials are not provided; contact any commercial cable vendor for the
required parts.
