Upgrading firmware
Firmware on the Network Access Controller is upgradeable in all operating
modes. It is highly recommended that the installer upgrade to the most recent
firmware version upon installation.
Note: It is recommended that firmware upgrade be performed via IP or USB
where possible, since it is faster than upgrade via a ChallengerPlus panel.
