We have an APC Symmetra 80KVA UPS and an IBM iSeries. We are looking to connect the iSeries to the Symmetra. The problem we are faced with is that the iSeries and the Symmetra are located in a different room, approx. 50-75 feet away from each other. What is the best method for connecting these two pieces of hardware, as I believe 50 feet is well over the limit of an RS-232 Serial Cable.
