Module Problems
Restore the module. Lift up the module to disengage it from the rod
at the top of the carrier.
Connect the trunk and extension cords.
Attach a tag, error printout, or any information that will help identify
any visible problems, failure symptoms, and relevant error reports.
Checking Unlabeled Wiring
If a label is missing or damaged, use a tone device and a telephone handset to
match like wires.
You need the following tools:
Tone device
Telephone handset
Telephone cord with an 8-pin modular plug
4-pair patch cord
Diagonal pliers or wire strippers
To match like wires, follow the steps below.
Insert the telephone cord's 8-pin plug into an outlet on the floor
area.
Using diagonal pliers or wire strippers, cut off the end of the
telephone cord to expose the pairs.
Choose a single pair and then untwist the wires.
Attach to each clip one wire from the pair you have chosen. The
clips extend from the bottom of the tone device.
Turn on the switch on the outside of the tone device.
You hear a high-pitched, alternating signal.
