8 machines could be upgraded from V1 to V4 with existing fibers. 4 of the remaining 5 machines (PSL and SUSAUX) could be upgraded by swapping fibers around, assuming those with no markings are good spares. I would presume the SUSAUX machine upgrade would likely happen around the time the new IO Chassis are installed, at which point this becomes moot.
