2.4 Upgrade the Firmware and Reboot the Intercom
Note
To guard against failed firmware upgrades, units shipped from CyberData with firmware
version 5.1.2 and later feature a built-in "fail safe" mechanism. Note that field upgrading
earlier units with v5.x.x will not allow for this feature.
Note
Any units that have shipped with firmware version 6.0.0 or later will not be able to run
firmware that is version 5.1.2 or earlier.
Note
The way that the integrity of the configuration file is validated has changed. Therefore, if
you downgrade the firmware (or if you downgrade, make changes, and then upgrade
again), the device may restore the factory default settings as if the configuration has been
corrupted. This problem is only present when upgrading or downgrading to or from
version 6.0.0 through 6.0.5 and version 6.0.7 and later.
To upload the firmware from your computer:
1. Retrieve the latest Intercom firmware file from the VoIP Emergency Intercom
