initialize and restore service.
3. In addition to collecting the pre-reboot Serial Interface text capture file, after the CDM-840
reboots you must retrieve its onboard data collection files via Ethernet connection, and
transfer these files to the User PC:

settings;
• The “log0”, “log1”, and “log2” files, which contain debug information.

files to Comtech EF Data Product Support for evaluation.
