Caution: If the software update is not applied and the unit is power cycled users will need to
upload the .iso file again in order to update the system software. The .iso file will be wiped from
the system since it is held in volatile memory.
3.3.3 Declassifying the System
Some users may require that the ATS-6511 be declassified before shipping the system to a new
location. Doing this involves removing all non-volatile memory from the unit. Power the system
down and press lightly on the SD Card in the slot on the front panel. This will release the SD
Card. Simply remove the flash disk from the front panel. The flash disk must be destroyed per
the user's standard security procedures. A new flash disk can be obtained from Symmetricom.

User Interfaces
Software interfaces on the ATS-6511 are limited in their ability to provide users with real-time
control. Adjusting some system parameters during operation of the ATS-6511 can seriously
impact the timing performance of the unit and therefore the ability to adjust these parameters is
limited by the software. Once properly installed, the ATS-6511 serves as a stand-alone device
which requires little to no interaction. Remote error monitoring capabilities are provided as a
means to ensure that the unit is powered and operating properly.
3.4.1 Operating System
The ATS-6511 operates a Symmetricom modified version of FreeBSD. FreeBSD is a Berkeley
derivative of the UNIX operating system.
3.4.2 Telnet
One advantage of accessing the ATS-6511 via telnet is that multiple telnet sessions may be active
at once. It is recommended that users connect directly to the desired port based on the function(s)
they are going to perform.

Command Port (1700)
System commands can be issued to the ATS-6511 via the command port. These commands
provide a limited set of operations to be used for remote control of the system. Typically, a
remote monitoring station may record an error that indicates user intervention is required. The
remote monitoring station would then be able to access the command port via the Ethernet and
issue the commands required for recovering from the error. The following list provides a short
description of each command.
Note: All commands are in lowercase and the commands are case sensitive.
