Repairing damaged firmware
In the rare case that the firmware is damaged after a firmware upgrade (which might happen if the
appliance is turned off and turned on during the upgrade process), the appliance will remain in boot
mode. In this mode, the Power LED at the rear panel flashes at about 1 Hz, and the appliance
attempts to restore the firmware over TFTP using the following default configuration:
• TFTP client IP address 10.0.0.2
• TFTP target device IP address 10.0.0.3
• Upgrade file name equal to CMN-XXXX.fl, where XXXX is the 4-digit Compliance Model
Number (CMN) that is printed on the agency label of the appliance
To repair damaged firmware, complete the following steps:
1. Connect the appliance to a TFTP server (using a cross-over cable or hub), which is set up with
the default IP address (10.0.0.3).
2. Rename the upgrade file to the default file name (CMN-XXXX.fl).
The Power LED will flash at about 2 Hz when the appliance is downloading the upgrade file, and it
will flash at about 4 Hz when it is programming the downloaded file to flash. After it has restored
the firmware, the appliance reboots automatically and the Power LED is lit.
