The USB relay solution looks workable, although not real cheap... |
The USB relay solution is an awkward solution. It very much reminds me old cartoons of Gyro Gearloose and his inventions. I think there are other more standardized and simpler ways of solving this problem. BTW, an equivalent solution but way cheaper is installing a mousetrap triggered by a pressurized recipient with boiling water, caused by the heat produced within the device. The mousetrap would be equipped with blades that will cut the power wires off, interrupting power supplying... lol
Putting the jokes aside I wonder if there is a standard interface like ACPI in this switch, so that you can configure the thresholds for turning off the power supply.
The other option would be remotely monitoring the switch temperature by using a protocol like SNMP (or whatever protocol the device supports) and whenever occurs an overheat it sends a shutdown command directly to the UPS (it depends on what is your device's external power supply). There are plenty of cheap UPS that supports remote management. |
I have an old picture of how it looks like that Switch. It seems only Bob realizes what i speak about 
It's on my facebook, however talkchess doesn't allow to upload images it seems. Just urls allowed. So let me google for one.
Google for Mellanox MTS3600Q-1BNC
On ebay there is a good photo of it, showing the frontside and the back:

Forget monitoring the switch temperature yourself.
That would mean you need to modify the switch - basically design a new switch. The switch already automatically monitors stuff like fanspeed by the way and turns itself off in case of specific problems.
However there is not 'off button' on the switch. This is internal electronic logics of the switch.
Another issue is logics for the fans that blow to outside of the building and inside into the room.
It seems there is for 40 euro some Relais stuff that can be controlled by rs232 or usb, allowing to monitor up to 8 devices. |
