Courier® Console Port Server & Remote Power Switch Hybrid

with 4 Console ports and 2 AC PDU ports

Manage network devices and power cycle easily from any location

Manage network devices and power cycle easily from any location

The USRobotics Courier Console Server & Power Switch provides remote access for up to 4 console ports and control of up to 2 power ports over a single modem connection. Quickly reboot or configure routers, servers, and firewalls from remote locations when the network goes down or Out-of-Band is the only option available. Keep costs to a minimum and reduce rack space and maintenance by consolidating to a single console server power hybrid and just one modem, but retain the same amount of control. Know the connection and data are secure when used with our worldwide approved Courier Business Modems and have peace of mind with built-in security notifications. Designed specifically for easy use with Cisco routers, no special cables are needed and optional linefeed pacing† automatically prevents missed CLI commands when using a batch file to configure the router. This hybrid is ideal for IT managers responsible for maintenance and management of remote locations near or far.
