The tandem of D-Links new Enterprise Gigabit switches and DPS Series of Modular Redundant Power Supplies (RPSU) enables todays business networks with unmatched flexibility, performance, scalability, and availability.The modular design of the DPS Series of RPSUs enables companies to selectively and cost effectively deploy higher availability configurations precisely when and where they are needed most. When paired with a supported D-Link switch, the DPS-200, and DPS-500 provide uninterrupted fail-over, in the unlikely event of a mechanical power supply failure. The system integration between D-Links Managed Layer 2 switches, Layer 3 switches, and RPSU system, provide customers with the fundamental building blocks to create economical and scalable networks without having to sacrifice network performance and availability.
