PowerAlert Network Shutdown Agent (included free of charge on a CD) is designed to gracefully shut down the operating systems of computers that are not connected to a UPS system with a USB or serial cable. One example of applications that have no direct USB or serial cable connection is when a high-capacity UPS system distributes power (often through a separate distribution panel) to remote computers that are located in a different room or even on a different floor. Another example is when a computer cannot be connected to a UPS system with a USB or serial cable because the UPS system's communication ports are already being utilized. PowerAlert Network Shutdown Agent allows multiple computers to use existing network cable to "listen" for select events to occur (such as loss of power) with the remotely located UPS system before executing a graceful unattended shutdown of the computers’ operating systems. Compatible with Windows, Linux, MAC OS, VMWare, and more.
