SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
2. Operational and Diagnostic Testing
A. General
Usually, units require testing for one of the reasons listed below:
To verify the operational readiness of the unit during and after installation on an aircraft.
To verify that a fault exists and produce system reports for troubleshooting purposes.
To verify the operational readiness of repaired LRUs during re-installation on an
aircraft.
This section presents software loading and test and fault isolation procedures for the HSD
and HSD-X transceivers. All test and load procedures require using the HSD maintenance
utility program, which is accessed by connecting to the maintenance port of the unit.
B. Test and Fault Isolation Equipment Requirements
Table 4–1 lists the equipment required to access the HSD maintenance utility program
and perform operational and diagnostic testing and software loads on the HSD and HSD-X
transceivers.
Table 4–2 lists the optional equipment or information that, although not required, may
increase test efficiency or allow for optional diagnostic procedures. Equivalent
substitutions may be used.
