As for the tube, I'd chalk that up to a script mistake or the modelmaker didn't understand what needed to be there for that line to be accurate.
I bet there is a reserve photon tube somewhere it just hasn't been located. Each BOP like from ST3 "D11 class" has an emergency tube. Check this article out.
