Secure Console Management

The CM4000 family of console servers enables system administrators to securely access and control their data centers and networks from anywhere in the world. The CM4000 provides reliable and secure access to the serial console ports, embedded service processors and network console ports on Windows, Linux, SUN, HP and IBM servers. The CM4000 can monitor and control network infrastructure such as Routers, Switches, Firewalls, UPS, Remote Power, PBX, and much more.

Remote Out of Band Access

The CM4000 console server can be remotely accessed in-band through 10/000 TCP/IP or out-of-band through an external modem. All connections are secure to remote systems using robust advanced encryption. The CM4000 also provides a selection of filtering and access logging facilities which can be archived off-line. Access can be restricted by IP address, password or account. Administrators can securely control and manage their distributed networks of servers and appliances using the latest in console access. Available in 8, 16 and 48 port models, the IM4200 family of advanced console servers are the perfect fit for in band or out of band access to vital IT assets.
