Re: [WISPA] Trango reboot incident
Here I would stress the use of SNMP smart cards in UPS systems. They don't add that much cost to a site, and you get paid back the first time something like this happens due to the notification features. I just got notified a few days ago that a system of mine has batteries that have failed. So if I did not have this notification, I would be going along happily thinking I'm protected when I'm not and I would have about 60 customers down for a couple hours (if I was able to act immediately, that is).

RE: [WISPA] Trango reboot incident
I have seen when a UPS goes into a "Fault" during the transfer, it is enough to reboot a device because the transfer was too slow. I have also seen when the power company "Powers-Up" for the day, because of the morning rush, cause an over-voltage on the UPS and causes it to fault. If you put these two together, if the power company pushes up the voltage, it causes the UPS to throw an over-voltage, thereby putting it to battery. If the transfer wasn't fast enough, it could potentially cause the units to reboot. Try unplugging the UPS several times to see if it causes the reboot. Might also try jacking into the UPS and read the logs to see if it did trip for some reason.
