IBoot‑IO – Remote Power Control Unit

The IBoot‑IO is a network‑managed remote power switch designed for automated rebooting, power cycling, and device control in IT, AV, and industrial environments. It allows equipment to be turned on, off, or rebooted through contact‑closure inputs, relay outputs, or optional network control (depending on model). Commonly used for servers, routers, signage, and remote installations where physical access is limited.
