The 320 and 430 used a mixed pair arrangement. .. that is, both positive and negative on the same pair... one on each wire. The swapping is to enable a cmm4 to power a 450i which only supports power arrangements which have the same polarity on both wires in the pair.
The only other thing I would check on the syncinjector is to make sure it's really a gigabit injector inside, since it is possible that the wrong board got put in the case. But that's just my paranoia talking-we've never had one shipped with the wrong board to my knowledge. If you want to check this, the cover should come off with no tools, only a fingernail. The board should say gigabit in it.
