Currently CryptoGlance will look for an 'x' in the chip status that cgminer reports and will try to restart the miner. I'm not sure if the s7 reports it the same as the s5, but the s5 is what we build that feature for.
Hm.. need add some supports to restart miner via ssh, or if miner don't respond via API (Like frezz). Or, something like this - for miners add option - Run This Shell Script if miner go down (and put shell path to sh).
