One UPS cord to your server and the whole thing goes dark when that feed drops. This 1U automatic transfer switch keeps your single-corded gear alive by switching between two C14 inputs before you've even noticed the hiccup. Twelve C13 outlets for the loads that matter, 2000 VA of headroom, and full remote management through Web UI, SNMP, or CLI. The NMC3 module handles network port sharing, environmental monitoring, and enhanced security so you're not crawling into the rack at 2 am. Slots straight into EcoStruxure IT if that's already your monitoring stack. Two-year standard warranty, extendable to five years
