How to Ground in a DC Environment

In a Direct Current (DC) environment, a T1000 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" on page 6-3
• "How to Ground the Frame in a DC Environment" on page 6-4
• For each server in the heavy duty frame, use the procedure in "How to
Connect T1000 AS Chassis Ground from T1000 AS Chassis to Frame in DC
Environment" on page 6-7
• "How to Ground the Logic Connector in a DC Environment" on page 6-8
