The connector cable for RPS1000 is the RPSCBL1. This type cable is proprietary to Linksys. This is a 4-foot, 14-pin to 16-pin connector cable that enables connection of the RPS1000 redundant power supply to an external device. This allows the PSU to supply power to the connected device in the event that its power supply fails. The RPS1000 only comes with one RPSCBL1. Additional cables can be purchased thru Linksys.
