End of Procedure

Grounding a CS 1000E Call Server

The CS 1000E Call Servers are not connected to a ground bar. They are properly grounded when:

•the CS 1000E power cord is plugged into the rack’s AC outlet. The rack’s AC outlet must be grounded to its dedicated electrical panel. This is the preferred method.

•the CS 1000E power cord is plugged into a wall AC outlet. The

CS 1000E is grounded outside of the rack using the safety grounding conductor in the power cord. This method ensures proper grounding only of the CS 1000E itself. It does not provide grounding protection for other rack-mounted pieces of equipment. Therefore, ensure that other devices in the rack are properly grounded as required.

Grounding a Signaling Server

The Signaling Server is not connected to a ground bar. It is properly grounded when:

•the Signaling Server power cord is plugged into the rack’s AC outlet. The rack’s AC outlet must be grounded to its dedicated electrical panel. This is the preferred method.
