How to Ground in a DC Environment

In a Direct Current (DC) environment, a T1100 AS hardware system operates as a digital isolated
ground plane in a central ground environment and requires a single connection to the central
ground window. The frame's ground cables must provide the sole grounding connection between
the entire frame and the central office grounding.
Perform the procedures in the following sections:
How to Prepare the Cables
How to Ground the Frame in a DC Environment
For each server in the heavy duty frame, use the procedure in

How to Prepare the Cables
Use this procedure to prepare each frame and logic ground cable.
1. Butt and strip the ends of the green ground cable (P/N 690-0108-07 for the frame ground and
P/N 690-0131-01 for the logic ground).
2. Slide a piece of clear heat-shrink (P/N 804-0229-01 for the frame ground and P/N 804-0228-R01
for the logic ground) on the butted end of the cable below the stripped end.
Move the heat-shrink past the stripped portion of the cable to allow access to the uncovered
wire.
3. Apply a thin layer of non-oxidizing grease to the uncovered wires.
4. Slide the cable lug (P/N 804-0977-R01 for the frame ground and P/N 804-0817-R02 for the
logic ground) over the stripped cable.
Crimp the lug on the cable, using an embossing crimper. The stripped cable must fill the lug
completely to the end of the barrel and be visible in the end window of the lug.
