6. TROUBLESHOOTING AND TESTING
Troubleshooting Methodology
Troubleshooting trees are provided for resolving the most common Reader issues. A Test and
Replace methodology is used for servicing the Reader system. The general steps are:
1. Test all symptoms that may have attributed to the reported system fault. Use the following suggestions to
reveal faults:
 Examine the Reader status on the Reader browser STATUS page (see Reader status,
page 46).
 Examine the RF channel statistics (page 50).
 Examine the trouble log files for any reported issues with the Reader (page 137).
 Observe the status LEDs on the Reader front panel (see LED Status, page 184).
Replace a suspected faulty component.
Continue with symptom testing and component replacement until there are no fault symptoms.
