Liebert CommSure Redundant UPS Interface


Liebert CommSure Redundant UPS Interface

Redundant UPS Automated Switching and Shutdown Solution

Liebert CommSure redundant UPS interface allows network managers to create their own high availability power system using existing UPS systems. The system eliminates false shutdown signals that occur when separate UPS systems are used to power computers with redundant power supplies.

Liebert CommSure permits two Liebert UPS systems to function together as a redundant, high availability power system when used with computers with two or more power supplies. The unit assures that computers will continue to operate as long as power is available from one UPS or both. If power is unavailable from either UPS, Liebert CommSure, using Liebert MultiLink software, will automatically shut down your computers in an orderly manner. 50Hz or 60Hz.
