How do we do something like a power cycle to reset the O's and X's on the chips through SSH?

For example, sometimes I see X's on the chips and when I reboot through the GUI, it doesn't get corrected. It's only when I manually do a power cycle by powering it off and on from the power button is when all the chips turn back to O's on the status page.

The reason I am asking is because sometimes I get X's and i reboot it from the GUI remotely through a VPN and it doesn't get fixed. I don't want to have to keep going there and manually power cycle it every time because my S4 is located about an hour away and it's a hassle =(.

Any ideas?
