Post Installation Procedures
How to Connect T1100 AS Logic Ground Port to Logic Ground Terminal Strip
1. Connect one end of the logic ground cable with the 15-pin connector to the port labeled "Logic
Ground" at the rear of the T1100 AS chassis.
This cable does not need any special preparation and can be used as delivered with the server.
2. Connect the other end of the cable to one of the screws on the logic ground terminal strip at
the top right side of the frame.
Do this for each server. See
page 91.
3. This procedure is complete.
Next, go to How to Verify the Ground in a DC Environment
How to Verify the Ground in a DC Environment
After all frame components and all frame and logic ground cables are installed, the hardware
tester must verify the frame and logic grounds. Power-up the frame using the procedure described
in How to Power Up
ground at the position show in

How to Ground the Logic Connector in a AC Environment

This section describes how to attach the logic ground cable to the logic connector at the back of
the server.
WARNING: Be sure that there is no connection between Tekelec equipment logic
ground and the logic ground of any other telecommunications equipment.
Note: Grounding for AC systems is provided through the AC electrical circuit; however, the
T1100 AS frame can be grounded with an isolated frame ground. Customers are responsible for
providing the connection from the LSMS frame to the customer frame grounding point.
1. Attach one end of the logic ground cable to the logic ground port at the back of one of the T1100
AS servers.
Note: This logic grounding procedure applies only when you have exactly two T1100 AS
servers in an AC cabinet. If you have only one server, or more than two servers, contact Tekelec
Customer Care Center for assistance.
Next, attach the other end of the logic ground cable to the logic ground port of the other server
as shown in
