Model 2616RC T-DAC User Manual

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”. Refer to table 6 for a list of common symp- toms and suggested remedies.

Note The following information assumes that there is only one failure involving the Model 2616RC 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”.

Note When removing the 2616RC from the chassis, follow the procedures

 

cited in “De-activating the Model 2616RC” on page 59.

Note When re-inserting the 2616RC into the chassis, please follow the pro-

 

cedures cited in “T-DAC blades installation” on page 20.

Problem

Corrective Action

 

 

POWER LED (green)

To verify that power is being supplied to the Model 2616RC via the Patton ForeFront chassis

is extinguished

power bus: verify that at least one chassis power supply module is installed in the chassis

 

and functioning normally.

POWER LED (green) is

The 2616RC has detected a power failure on a power bus. There may be a problem with

flashing

the Patton ForeFront chassis power system which feeds the Model 2616RC such as a failed

 

power supply module in the chassis. The Model 2616RC will function normally with one

 

power supply. Inspect the power supplies in the Patton ForeFront chassis to identify and

 

replace the failed power supply module. If no failed power supply is found, or if the

 

POWER LED continues flashing, contact 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 2616RC from the Patton ForeFront chassis, wait 30 seconds, then re-

 

insert the Model 2616RC into the Patton ForeFront chassis and see if the problem disap-

 

pears. If the CPU FAIL LED remains lit after the Model 2616RC completes the power-up

 

cycle, contact Patton Technical Support to determine if the T-DAC needs to be replaced.

ALARM LED (yellow) is

Indicates The 2616RC has detected a minor or major alarm condition.

lit

 

 

 

SYSTEM LED (green) is

The Model 2616RC is not functioning properly. As soon as possible, remove the Model

not flashing

2616RC from the Patton ForeFront chassis, wait 30 seconds, then re-insert the Model

 

2616RC into the Patton ForeFront chassis and see if the problem disappears. If the SYSTEM

 

LED remains lit after the Model 2616RC completes the power-up cycle, contact Patton Tech-

 

nical Support to determine if the T-DAC needs to be replaced.

ETHERNET LED (green)

A valid Ethernet link has not been detected. Verify that the Model 2616RC is connected

is extinguished

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.
