Tripp Lite's Hot-swap PDU systems enable live-replacement of standard UPS systems for maintenance with no interruption of connected server or networking loads. Dual input power cables support PDU connection to separate Utility and UPS power sources. Manual transfer switch with lighted status indicators controls the source of power to connected equipment between Utility and UPS. Set the switch to UPS during normal operation and connected equipment will receive full-time conditioned power from the UPS. Set the switch to Utility to momentarily power connected equipment from the Utility line cord and bypass the UPS while the UPS system is removed and replaced with a fresh one. Once the new UPS is up and running with all data and electrical connections restored, set the switch back to the UPS setting to once again provide fully-conditioned UPS power to connected equipment.
Power distribution units, or PDUs, are essential devices for computers and networking equipment. Through these units, power supply is effectively shared among all pieces of computer equipment within the network, ensuring that the network is always up and running. PDUs are either floor-mounted or rack-based. Also called power strips, rack-based PDUs are more commonly used for office computer networks today. These devices are equipped with a range of functionalities; some PDUs are simply equipped with multiple outlets, while other units provide additional functionalities of switching and metering. Switched-and-metered PDUs have outlets that can be individually switched on and off as well as a display for current loads.
