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.
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 Table 1 on page 34.
