PowerDsine Redundant Power Supply PowerDsine Redundant Power Supply
The PowerDsine? redundant power supply (RPS) increases reliability for data, voice and video networks by ensuring reliable safe power for all PoE applications including VoIP, wireless LAN, IP security cameras, thin clients and other end terminals.
When connected to a compatible PowerDsine PoE Midspan, the RPS ensures continuous full power operation and PoE delivery to all powered devices in case the midspan internal power supply or primary AC network fails.
The RPS architecture is based on current sharing, enabling seamless and continued operations. Additionally, the RPS offers full power upgradability by supplying the midspan with an additional source of power, working as an additional External Power Supply (EPS) doubling the midspan抯 total power supply capability.
A redundant power supply is two or more units in one package, where each can supply the full amount of power to the system, such that if one fails, the other will take over and the system never goes down. In most modern redundant power supplies, the dead one can be replaced while the system is still running, called hot-swapping. http://www.tc-surestar.com.tw/
