Overview

Digi CM allows IT administrators to securely monitor and control servers, routers, switches
and other network devices. It provides access to the serial port of key network equipment
from anywhere on the corporate TCP/IP network, over the Internet, or through dial-up
modem connections. Popular applications for Digi CM include access to servers (e.g.,
UNIX, Linux, Sun, Windows Server 2003), routers/switches (e.g., Cisco), firewalls and
more.

Digi CM employs SSH v2 encryption to keep server access passwords safe from intruders,
and supports all popular SSH clients. It also includes support for RADIUS, TACACS+,
Kerberos, LDAP and other user authentication programs. Users may perform key console
management functions and configuration using Digi’s best-in-class Web User Interface built
right into the unit. Intuitive port naming and multi-level menuing make the Digi CM the
easiest-to-use console server on the market.

Other premium features include port logging, server clustering, email/pager/SNMP alerts
and Automatic Device Recognition. Digi was first with Automatic Device Recognition
technology which allows the server to poll its attached devices and autoconfigure itself with
the device type, name and OS version. Digi CM also offers a PC Card slot for dial-up
modems, wireless network cards or Flash memory cards.

Digi CM connects to console serial ports of Cisco and Sun devices using
standard CAT5 cables for hassle-free straight-through cabling. Converter
cables/adapters are offered for pain-free connections to most servers.
Digi CM is available in 8-, 16-, 32- and 48-port models, in a
19” 1U rack-mount form factor. DC powered versions with dual inputs are
also available for fail-safe operation. Test drive the Digi CM today at
