Section IV – TROUBLESHOOTING
12. Fault Overview
Problems with Iridium Pilot Land Station can be grouped together in several classifications:
1. Fundamental problems where the unit will not function locally over the Ethernet port (no diagnostic page
access) or the telephone lines are non-functional.
a. Check the LED status and follow the fault tree
i. Possible power supply issue
ii. Possible ODU/IDU interface cable issue.
2. RF/Network Problem. Local communications over the Ethernet port works but connections to the internet
and the PSTN are non-functional.
a. Check LED status and status and diagnostic pages and follow the fault tree
i. Possible SIM card issue
ii. Possible GPS issue
iii. Possible unit “black listed” at the gateway
iv. Possible equipment issue
3. Performance Problem. Both local and Satellite communications work but voice and/or data issues persist.
a. Possible interference or blockage issue
b. Possible equipment issue.
13. LED State Table
• The Data and Voice LEDs will be off until the unit has initial contact with the Iridium network to register and
verify service.
• The “Status” LED states were changed in firmware version AO100002 and newer. The LED state table, above,
reflects this new functionality. Older versions of code should be updated to the current version to take
advantage of performance improvements and enhancements.
14. Troubleshooting
There are 8 LED indicators located on the IDU that can be used to initially diagnose issues with the system.
Initially these indicators may be the only feedback to service personnel if the unit has a fundamental issue.
During trouble shooting service personnel need to determine if the unit has previously worked and recently
failed or if this is a new installation that has never worked. While troubleshooting consider changes in
performance and how they may relate to other equipment that has been added.
