5.1 Restoring the Operating System
The 4200 Rack Mount Topside Processor contains a 500 GB hard drive for both the operating system and
the application software. A separate 2 TB hard drive is included for data recording.
The hard drive can be backed up and restored using the supplied USB in the unlikely event of its failure.
For instructions on how to restore the operating system, refer to APPENDIX B: Backup and Restore.
5.2 Disassembling and Reassembling the Tow Vehicle
The procedures below describe how to disassemble and reassemble a tow vehicle to access and remove

vehicle. Turn off the topside processor and disconnect the tow cable
