3COM 3C565047A SUPERSTACK II 240W RPS

No power means no computing. With today's mission-critical networks, no network manager wants to be at the mercy of equipment or building power supply failures, and 3Com has necessary solutions to fit a range of fault-tolerance needs. Its SuperStack II Redundant Power System protects up to four SuperStack II system devices from internal power supply failures. The SuperStack II Redundant Power System is an industry first for stackable systems; redundant fans protect against failures caused by overheating-an important option for mission-critical environments. Two load-sharing bulk power supplies with two fans are fed by two independent AC lines. If one power supply or fan fails, the redundant unit automatically takes over.
