Introduction; How To Connect Frame Ground And Logic Ground - Tekelec 1100 Hardware Manual

Post Installation Procedures

Introduction

This chapter describes the activities that should be performed after either of the following types
of installation:
A heavy duty frame that contains T1100 AS hardware has been installed
T1100 AS hardware has been installed in an existing frame
Note:
Some of the figures in this section show the Tekelec T1000. The T1000 is identical in size to the
T1000, and the frame installation instructions are the same for both chassis.

How to Connect Frame Ground and Logic Ground

The procedures in this section must be performed before turning on the power to the frame. To
ground a T1100 AS hardware system, the following tasks must be performed:
Prepare the ground cables (required only in a DC environment); see
on page 85
Ground the frame (required only in a DC environment); see
Environment on page 86.
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.
Ground the chassis; see either of the following:
Ground the logic for the T1100 AS unit; see
on page 89 or
Verify the grounding; see one of the following:
How to Verify the Ground in a DC Environment
How to Verify the Ground in an AC Environment
DANGER: Strictly observe all grounding requirements to reduce the risk of electric
shock.
