Before performing the detailed testing and troubleshooting procedures provided in this
manual, read the following Troubleshooting Checklist. Use the Troubleshooting Checklist to
make sure that you have not missed any key steps in the HSD-X and HSD-Xi terminal setup.
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-X and HSD-Xi
terminal. Contact Inmarsat for a list of available service providers at:
Inmarsat Customer Care
99 City Road, London, EC1Y 1AX
Tel: +44 20 7728 1777
Fax: +44 20 7728 1142
E-mail: customer_care@inmarsat.com
2. Has your account been activated?
Once registered, your HSD-X and HSD-Xi terminal is assigned terminal identification
numbers called FWD IDs. The HSD-X and HSD-Xi terminal 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 LES level. New terminals 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
terminal.
NOTE: To verify that the service registration information has been validated at the
LES, call 33 POUND KEY for assistance. Confirm with the LES operator that
the FWD IDs assigned to your terminal are valid and active.
3. Is the HSD-X and HSD-Xi terminal seated properly?
In cases where the HSD-X and HSD-Xi terminal 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 diagram.
• Make sure that the HSD-X and HSD-Xi terminal is fully inserted into the tray and
that the front hold-down screws are properly tightened to secure the terminal.
4. Is all cabling attached correctly and securely?
Broken connections and improper cabling are the most common causes of HSD-X
and HSD-Xi terminal malfunctions. Before proceeding with testing and
troubleshooting, complete the following checks:
• Check that all cables and wiring are routed and connected correctly and securely.
• Make sure that the terminal is installed with the correct power source.
