5.5 How to Connect the System Cables
This section provides an overview of cable connector locations and cable routing. Procedures for removing and replacing specific cables are covered within the removal and replacement process of the assemblies with which these cables are associated.
5.5.1 Before You Begin
Complete these tasks:
5.5.2 What to Do
-
Identify the cable that you want to install or replace. Use the information in the following table and illustrations to determine where to connect each end of the cable.
-
Install the cable according to the routing and cable management instructions provided in the table.
Each cable connector is keyed so that it can be connected in only one way.
