For the life of me, I dont understand why the "Reboot" feature is nested within the "System" tab, and you have to actually confirm that you want to reboot the CMM5 controller.
Not that its a bad Idea to confirm a reboot, however, The big red "System Shutdown" is on the main bar, and if breathed on, will shut down the CMM5 controller. This then calls for a trip to the site to power cycle the device.
Again, just not sure why it was implemented to "Confirm" a reboot, but blindly shutdown on a single press without confirmation. As luck would have it, Cambium Engineers just blindly shut mine down while poking around in the CMM5 looking to see about an unrelated issue.
