M7/M7L/M7LT Modular Satellite Modem Maintenance

M7/M7L/M7LT - Rev. 0.05 4-11

At the end of the extraction process,

the M7 will reboot. At this point, the

current browser session will

terminate and the “Login” page will

display. Reenter the login

credentials to verify the update

process was completed properly.

In the “Unit-Test” tab, the current

updated firmware will show in either

“Firmware Flash 1 or 2” and display

“Running” to indicate it is the

operating firmware. The previous

firmware will be maintained in the

other flash location and can be

called up if there is an issue with the

new update.
