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 39).

• Examine the trouble log files for any reported issues with the Reader (page 80).

• Observe the LED Indicators on the Reader front panel (see LED Indicators, page 112).

2. Replace a suspected faulty component.

3. Continue with symptom testing and component replacement until there are no fault symptoms.
