APPENDIX B: TROUBLESHOOTING CHECKLIST
Before proceeding to the detailed testing and troubleshooting procedures provided in this
manual, read the following
QuickStart Troubleshooting Checklist. The QuickStart
Troubleshooting Checklist provides answers to common HSD system activation
questions.
1. Have you registered with a service provider to activate service?
You must register with an Inmarsat-authorized service provider to activate an account to
access the Satellite Communications network using an HSD Aeronautical Transceiver.
Contact Inmarsat for a list of available service providers at:
Inmarsat Customer Care
99 City Road, London, EC1Y 1AX
Tel: [phone]
Fax: [phone]
E-mail: [e-mail]
2 Has your account been activated?
Once registered, your HSD Transceiver is assigned terminal identification numbers called
Forward IDs (FWD ID). The HSD transceiver must be strapped accordingly. Refer to
"Installation" on page 3-1 for detailed strapping and installation instructions.
Note: The service registration information may take a few days to be incorporated into
the system databases at the Land Earth Station (LES) level. New units being
commissioned are not validated by the LES until their customer database has been
updated by Inmarsat to reflect the registration and activation of your unit.
To verify that the service registration information has been validated at the LES,
call 33 # for assistance. Confirm with the LES operator that the forward IDs assigned to
your unit are valid and active.
3 Is the HSD/HSD-X transceiver seated properly?
In cases where the HSD or HSD-X is not fully seated into the ARINC 600 connector (to
the rear of the Fan Tray), the user may experience intermittent system operation. If
intermittent system operation occurs:
Check that the polarization pins are installed correctly as indicated on the applicable
Outline and Installation drawing.
Ensure the HSD/HSD-X is fully inserted into the tray and that the front, hold-down screws
are properly tightened to secure the unit.
4 Is all cabling attached correctly and securely?
Broken connections and improper cabling are the most common causes of HSD units “not
working.” Before proceeding with testing and troubleshooting, complete the
following checks:
• Check that all cables and wiring are routed and connected correctly and securely.
• Ensure the unit is installed with correct power source.
• Verify that all external user and networking devices (for example: terminal adapters,
routers, fax, telephones, computers) are connected and configured properly.
