Troy, Related to GFI.... We've removed all GFIs from our implemntations for this reason. We try to redesign our isntall plan to a way that code wont require the GFIs.
As far as Dragonwave versus Mikrotik, one rebooting and not the other..... The Dragonwave draws more current than the Mikrotik to operate, so its not surprising, if a short brownout spike occurred that the power flowing was enough to keep the mikrotik running, but not the Dragonwave. One way to help with that is to have a overspec'd UPS. Running a UPS at 44%, power storage capacity in its capacitor's will be less sufficient to cover for power drops, than if the UPS was run at a lower load. Another way to deal with it is to modify the setup to a Dual realtime power feed situation, so better chance one of teh two systems will deliver power, before a switch to battery, or if a breaker trips on one of the power circuits.

Specs: Generac 8KW generator Automatic Transfer Switch APC 450 rack mount UPS Mikrotik RB1200 Mikrotik RB435 (3x 802.11n sectors) Dragonwave Compact Horizon #1 Dragonwave Compact Horizon #2 (I don't know how many horses, chickens, goats, pigs, and other critters are onsite, but I don't think they're an issue). Total load on the UPS is at 44%, estimated run is 25 minutes (long enough for the generator and switch to do their thing). Radios grounded to the tower, tower grounded and bonded to the shack. Shack has two rods (panel -> Rod -> Rod -> Generator). Everything inside is bonded as well, including the drain wires on all the Cat-5. Yesterday, the Dragonwaves rebooted several times during the storm, but neither RB lost power even once. Any guesses? I'm sleeping on it over the weekend, but probably need to get it figured out before too many more storms come over the mountains.

One of them tripped last night, causing me to have to put on some 80 miles just to push a button (yes, it could have been much worse). Is there anything to prevent stupid outages like this from happening without violating code? Thanks, -- Troy Settle, Network Administrator The Wired Road Authority 1117 E.
