Troubleshooting the SynchLink Module

This chapter describes how to troubleshoot the ControlLogix SynchLink
module.

Using the Status Indicators

The SynchLink module uses status indicators to show SynchLink and
communications status (red/green) and a bi-colored LED for module "OK"
(red/green).

During power up, an indicator test is done and the following occurs:

• The "OK" indicator turns red for 1 second and then turns to flashing

green if it has passed the self-test.
