The emergency bypass switch on the UPS works.
This is the first time we’ve had to test it. Somehow, the UPS went into a tailspin and went into bypass mode and wouldn’t come out. So I switched to manual bypass on the back of the unit and threw the emergency bypass switch, turning the UPS off. It was nice to see the machine room keep humming. After restarting the UPS, it seemed fine, and we got a working NIC on the UPS again out of the deal (it’s been flaked out since last summer sometime).
