can't quote the book but my 6 consoles are about a quarter of a mile from the switch. power tn's are on the switch, not local to the consoles.. how far are you trying to run them?

the white blue pair is your 1st tn pins 26 1
the white orange pair is your 2nd tn pins 27 2

the tip side of your two power tn's connect to the red orange pair pins 32 and 7 (red orange pair)

the ring side of your two power tn's connect to the red green pair, pins 33 and 8

the 2250 will work without power if you have the 1st two pair connected, the lamps may be dim.. the red blue pair is positive, the red orange pair is negitive... i usually connect a new console in the switchroom before i send it through tie cable.. just quicker that way for me.

haven't ran into that problem. like i posted mine are over 500 meters if my metric conversion is right. power is not used for talk battery. does a 3900 set on the same voice pair work.. white blue is the speech path for that set. none of my tie cable is cat 5, it's all old cat 3, my 6 consoles work in the same 50 pair, i have grounded some of the vacant pair in that tie to discourage crosstalk... the trouble does not sound as much like distance as it does bad pair..
