1. Use the browse button to locate the “.hex” file.
2. Click on the Update button to begin the upgrade. The flash loader will automatically update the inactive memory bank.
The active memory bank is indicated by the green dot next to bank A or B at the bottom of the page.
3. Do not interrupt the upgrade process once the file transfer has begun! DO NOT hit your browser’s back STOP or BACK
button during file upload!
4. Upon reboot, the CTM will boot to the memory bank that was just upgraded if successful. REFRESH the flash loader
page at the currently set IP address to display the main page. In case the process was NOT successful, the CTM will reboot
using software in the OTHER memory bank, if possible. As a last resort, the CTM will reboot back to the flash loader page.
Because the Flash Loader software is unable to do anything except, load the flash memory, the front panel lamps will not be op-
erational while the CTM is in flash loader mode. They will be in whatever state they where in when the system rebooted into flash
loader mode. Likewise for the GPS and Control CPU status.
There’s no logging, no status updates, no monitoring of the GPS timing to handle backup timing, etc. The power supply & circuit
breaker system will still work, as these operate on their own, but these events will not be logged. The Timing pulse, power supply
system, and the backup oscillator system will still work, but may drift quite a bit if the GPS goes down while in flash loader mode.
It is still best to do flash loader operations during non-peak traffic load times in case something goes wrong. Users should ONLY
use the flash loader when absolutely necessary. Its also not a good idea to enter flash-loader mode and leave it there for long
periods of time in case the GPS goes down while in flash loader mode. Radio operation will not be affected as long as the new
firmware has the same CPU version as the current firmware revision.
Update Firmware
The Update Firmware button is used to change active firmware memory locations or load new firmware to the CTM.
Change Active Firmware:
Use this button to change the active CTM firmware package. Radio operation will be unaffected as
long as the CPU versions between the two packages remain the same. Press the Upload Firmware File button to bring up the
Flash Loader page which will display the current firmware versions in each memory location. Once in the Flash Loader page you
can go back to the main page by selecting the memory bank you wish to boot to, then press the Go to Selected CTM Main Web
Page button.
Upload Firmware File:
When pressed, the CTM will reboot the network port and bring up the Flash Loader page. Here you can
load the latest revision of the CTM firmware. Depending on your browser settings, you may need to refresh the page to display the
Flash Loader page.
