Pro Power (authorized re-seller of Netcom2 monitoring hardware+software)
Currently have a call in to Jeff James at Pro Power for quotes on the Mitsubishi Netcom2 device+software. Ballpark estimate is $730 for the box + $10/each for ability to have shutdown notices sent to individual computers. One $10 license may cover multiple computers, need to confer with Jeff james.
To connect this box into our system, we would run multimode fiber from the shed into the SPR and use a pair of 100Mbps transceivers that we already have on site.
Response from Pro Power this afternoon, verbal quote: $550 for netcom2 + 10 shutdown licenses. Jeff James should send me official quote over email tomorrow (16 mar 2011)
