Appendix C. MAINTENANCE AND
TROUBLESHOOTING
C.1 Overview
This appendix serves to assist operator and maintenance personnel in the checkout, maintenance
and troubleshooting of the UT-4500-A Series Upconverters.
Comtech EF Data recommends that spare replacement converters be used to replace converters
removed from the system for maintenance. Troubleshooting procedures are provided for fault
isolation to the module level.
The input and output signals, the interconnecting cables and the location of the modules are as
shown in Figure C-1.
