Table 4. Symptoms
Problem
Corrective Action
PWR LED (green)
is extinguished
To verify that power is being supplied to the Model 6081RC via the CPCI chassis power
bus: verify that at least one chassis power supply module is installed in the chassis and func-
tioning normally.
PWR LED (green) is
flashing
The 6081RC has detected a power failure on a power bus. There may be a problem with
the CPCI chassis power system which feeds the Model 6081RC such as a failed power sup-
ply module in the chassis. The Model 6081RC will function normally with one power supply.
Inspect the power supplies in the CPCI chassis to identify and replace the failed power sup-
ply module. If no failed power supply is found, or if the POWER LED continues flashing, con-
tact Patton Technical Support to determine if the Network Access Router should be replaced.
ENET LED (green) is
extinguished
•
A valid Ethernet link has not been detected. Verify that the Model 6081RC is connected
by means of an Ethernet cable to an Ethernet hub, switch, or workstation and that both
ends of the cable are plugged in.
•
Verify that the hub, switch, or workstation is powered on.
•
Verify that the correct cable is being used—either a straight through or cross-over cable
depending on whether you are connecting to a workstation (PC), hub, or switch.
•
Replace the Ethernet cable. If the problem still exists, contact Patton Technical Support to
determine if the Network Access Router should be replaced.
