The Juniper Networks EX series Ethernet switches redundant power system (RPS) acts as a backup device that provides redundant power to up to six connected Juniper Networks EX2200 and EX3300 Ethernet switches, with or without Power over Ethernet (PoE). The RPS ensures operational continuity following a main power supply or power feed failure, and can be easily managed and configured from the command line interface of any connected EX series switch.
