Maintenance
Upgrading Set Firmware
Upgrade the firmware for SUPERSET™
4025
,
SUPERSET 4090,
SUPERSET 4125, and
SUPERSET
4150 telephones, only if the
revision on the system is higher than the set revision. The boot code
and the firmware revision levels must be checked.
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.
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 Table 1 on page 34.
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.
