Maintenance and Troubleshooting

Carrier Problems

Typical carrier problems include power supply failure, sudden failure of one or more modules, or
system problems that cannot be isolated to a specific module. If you find a problem with the carrier,
it must be replaced; carriers cannot be repaired in the field.

Removing the Faulty Carrier

1. Remove the cover from the carrier. See "Installing/Removing the Cover on the Carrier" in
Installation.
2. Backup system programming to a floppy disk or memory card.
See "Backup" in Programming Basics to backup to floppy disk, or Appendix D, "Backing up
with a Memory Card" to backup to a memory card.
3. Power down the system by turning off the components listed below, in the order given.
a. Power supply on the basic carrier
b. Power supply on each expansion carrier
4. Unplug the control unit from the AC outlet.
5. Remove the processor, the power supply, and all other modules from the faulty carrier. (If you
prefer to remove the cords first, make sure that they are labeled.)
6. Put the modules aside, in order, so that you can reinstall them later in the replacement carrier.
7. Remove all modules from the carriers to the right of the faulty carrier.
8. Disconnect the ground-screw on the carrier from the approved ground.
9. Loosen the screws holding the carrier onto the backboard.
10. Slide the carrier to the right until the connector disengages from the carrier to the left.
11. Pull the carrier away from the wall so that the screws slip through the large screw holes.

Replacing the Carrier

After removing the faulty carrier, use the steps below as a guideline for installing a new carrier.
1. Install the replacement carrier(s). See "Mounting an Empty Carrier" or "Mounting a Populated
Carrier" in Installation for instructions.
2. Replace the modules with all cords connected as they were before.
