Guess that would work to. Have a cheapo 5 port switch plugged into AC that is feeding the UPS and turn on the Ethernet running check on the MTs secondary Ethernet port. If the link fails the running status on the interface will change from running to down and a script could trigger on it.
The assumption here is that you have nothing your communicating to over the Ethernet ports that are not ran by UPS or don't even use the Ethernet port at all for anything else but Power on the RB (assuming again we use a RB). If the Ethernet is being used and plugs in to devices you could setup so you have the cheapie 5 port switch plugged in to AC with no UPS and ether2/3 on the RB plugs in to switch and another Ethernet device with an assigned ip in same subnet as ether2/3 plugged in to the same switch. So only way the two devices can talk is as long the switch is up and running. If the switch goes down the netwatch created script will fire of an e-mail or your network monitor program alerts on the lack of communication over the purpose built link. In either setup this requires a piece of "throwaway" equipment that is designed to go down when AC power fails. This device could in all reality be just about anything Ethernet based with or without an ip assigned to it. If the device does not have the capability to assign an ip to it then the UPS powered unit have to be bit smarter and be able to detect the lack of Ethernet link and react to it. If it has the capability to have an ip assigned to it then your NMS could react when it can no longer ping this device and the equipment powered by the UPS doesn't matter how smart or dumb it is. / Eje CTO WISP-Router, Inc. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jayson Baker Sent: Saturday, August 01, 2009 2:49 PM To: WISPA General List Subject: Re: [WISPA] TP--UPS-DC-12-9 Why not use a board with a spare Ethernet port (i.e. a 433 or whatever), and wire one port as a loopback through a relay. The relay could be tied to AC, so the Ethernet link would drop if AC went off. If could be tied to the voltage of a DC supply, so you'd know when the DC voltage was high/low. Just ping the IP of the interface you're running it off of. This way, you can use standard monitoring applications to detect power. It's very simple to do, and costs less than $10.
