plugged into computers. Each DOM has it's own mainboard and an IP
address, and all 60 DOMs from "in-ice" and 4 from IceTop are plugged
into a single "hub". Each string has it's own hub, and we have now 79
strings out of the 86 projected upon completion next year. Each hub
is mounted on an electronics rack. It's a lot of hubs and cables, and
it's not trivial keeping all of them running all at the same time.
The white coats we are wearing prevent static discharge. It is
extremely dry here at the South Pole and at night with the windows
blocked by cardboard, you can see sparks from static when you shift
around under the sheets. A big shock can kill the cards in the hubs
and the coats are supposed to help with the static.
