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.

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:

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. 

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.

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.

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.
