5 • Troubleshooting and maintenance
The Model 2616RC is operating normally. No action rec-
ommended.
The Model 2616RC is not functioning properly. As soon
as possible, unplug both power cables from the Model
2616RC, wait 30 seconds, then plug the cables back
into the Mode 2616RC to see if the problem disappears.
If the SYSTEM LED remains lit after the Model 2616RC
completes the power-up cycle, contact Patton Technical
Support to determine whether the T-DAC needs to be
replaced.
Link status is nominal for the Ethernet port. No action recom-
mended.

A valid link has not been detected.
• Verify that an Ethernet cable is plugged into the hub, switch,
or workstation and the Ethernet port of the Model 2616RC.
