Thanks! Wow... can you read Chinese?
No sadly not. I'm not even good at reading English.
Considering the events and the chaps actions and demeanour, I'd speculate
that he responding to a non-urgent alarm reported by the equipment to the network operation centre.
Although it is a bit of a stretch to say so, I'd suspect a "low-voltage
battery disconnect" alarm. The power supply monitors the battery charge voltage, current and temperature and if it finds an abnormal situation, it disconnects the battery from the power supply. It does this to protect the batteries from over-charge and damage. Under these circumstances the
equipment keeps running, but would fail, rather than running, if the mains power was lost to the cabinet.
He's on the phone to the NOC. He knows exactly what needs doing and he's
done it a hundred times. Opens the cabinet door, closes the battery
disconnect breaker and Kaboom!
I feel for the guy, as almost everyone doing that job would do exactly the
same thing.
