1 1. Introduction Network equipment sometimes "locks-up", making it impossible to communicate. The RPB+ Remote Power Boot Switch can switch AC power on 5 individually controlled plugs, allowing attached equipment to reset (re-boot). ASCII commands are sent to the RS-232 Control Port to select plugs, and specify On, Off, or Boot operations. A convenient Status Screen shows On/Off conditions at each plug. RPB+ features include a security password, Location I.D. field, and plug labels to identify t
