Routine Maintenance
Boot Codes
The SUPERSET boot code must be at revision Boot 3.10 or greater or the
SX-200 system cannot successfully upgrade the set’s firmware.
The boot code appears when a set is first plugged in.
If you attempt to upgrade a set with a boot code lower than 3.10, the
system will erase the set’s firmware and you will not be able to download
the new firmware. The set then becomes unusable.
Firmware Revision Levels
The firmware revision level of the set that you are upgrading must meet the
firmware revision level stated in SYSTEM maintenance. Use the
SET_FIRMWARE STATUS maintenance command to identify the revision
level.
Firmware Commands
Access the firmware commands in the SYSTEM maintenance level and
then choose SET_FIRMWARE to obtain the softkeys to qualify your target
set. See the table below.

revision must be older than the firmware to be
downloaded.
ABORT_DOWNLOAD Removes specified sets from the scheduled
download.
FORCE_DOWNLOAD Forces the download to occur even if the set
firmware is newer than the firmware being
downloaded. This command allows a set’s
firmware to be returned to a previous firmware
version when required.
