Model 3096RC T-DAC Getting Started Guide
5 • Troubleshooting and maintenance
Introduction
This chapter describes troubleshooting and fault analysis that can be performed by the operator. If you require
more help, refer to chapter 6,
“Contacting Patton for assistance”
on page 86. Refer to
table 7
for a list of com-
mon symptoms and suggested remedies.
Note
The following information assumes that there is only one failure
involving the Model 3096RC and that if you perform the corrective
action listed, it will solve the problem. If you are unable to correct a
failure, refer to chapter 6,
“Contacting Patton for assistance”
on
page 86.
Note
When removing the 3096RC from the chassis, follow the procedures
cited in section
“De-activating the Model 3096RC”
on page 70.
Note
When re-inserting the 3096RC into the chassis, please follow the pro-
cedures cited in section
“T-DAC blades installation”
on page 25.
Table 7. Symptoms
Problem
Corrective Action
POWER LED (green)
is extinguished
To verify that power is being supplied to the Model 3096RC via the CPCI chassis power
bus: verify that at least one chassis power supply module is installed in the chassis and func-
tioning normally.
POWER LED (green) is
flashing
The 3096RC has detected a power failure on a power bus. There may be a problem with
the CPCI chassis power system which feeds the Model 3096RC such as a failed power sup-
ply module in the chassis. The Model 3096RC 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 T-DAC should be replaced.
CPU FAIL LED (red) is lit
CPU is unable to load the software from FLASH to RAM for operation. As soon as possible,
remove the Model 3096RC from the CPCI chassis, wait 30 seconds, then re-insert the
Model 3096RC into the CPCI chassis and see if the problem disappears. If the CPU FAIL
LED remains lit after the Model 3096RC completes the power-up cycle, contact Patton Tech-
nical Support to determine if the T-DAC needs to be replaced.
ALARM LED (yellow) is
lit
Indicates The 3096RC has detected a minor or major alarm condition.
SYSTEM LED (green) is
not flashing
The Model 3096RC is not functioning properly. As soon as possible, remove the Model
3096RC from the CPCI chassis, wait 30 seconds, then re-insert the Model 3096RC into the
CPCI chassis and see if the problem disappears. If the SYSTEM LED remains lit after the
Model 3096RC completes the power-up cycle, contact Patton Technical Support to deter-
mine if the T-DAC needs to be replaced.
ETHERNET LED (green)
is extinguished
•
A valid Ethernet link has not been detected. Verify that the Model 3096RC 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 T-DAC should be replaced.
