7.1 GTN Xi
Original GTN Xi Re-installed
If the removed GTN Xi is installed in its original position, no software loading or configuration setting
changes are required. This does not include units that were returned for repair, as their software and
configuration files are deleted during the repair testing progress. It is recommended to perform the
Connector Engagement Check (refer to Section 7.1.2.1) to ensure proper seating of the connectors.
New, Repaired, or Exchanged GTN Xi Installed
If a new, repaired, or exchanged GTN Xi is installed, the correct software must be loaded to the unit. Some
configuration files must be set. Refer to the summary in Table 7-1. Any enabled features, such as TAWS B
or ChartView, will not need to be re-enabled if the configuration module was not replaced.
This section covers the necessary steps to configure and test a replacement GTN Xi. The steps provided in
this section are only applicable for replacement of an equivalent GTN Xi (e.g., 750 for 750). If wiring
updates are needed, or the configuration module is being replaced simultaneously, refer to
GTN Xi Part 23
AML STC Installation Manual
for installation and configuration instructions.
