Digi CM Model Support
This manual of fers info rmation on Digi CM 8-po rt, 16-po rt, 32-port, an d 48-port
models.
Feature Overview
With Digi CM, administrators can securely monitor and control servers,
routers, switches, and other network devices from anywhere on the corporate
TCP/IP network, over the Internet, or through dial-up modem connections,
even when the server is unavailable through the network.
Digi CM employs SSHv2 encryption, to keep server access passwords safe
from hackers, and supports all popular SSH clients, as well as secure access
from any Java-enabled browser. It is the first console server to provide a
secure graphical u ser int erface for easy ou t-of-ba nd m anage ment of Micro sof t
Windows Server 2003 systems. It connects to serial console ports using
standard CAT5 cables, eliminating the hassles of custom cabling. In addition,
the Digi CM offers a PCMCIA card slot, for adding dialup modems or wireless
network cards. Flash memory cards can be used to save po rt logs and backup
configuration files.
Introduction
Digi CM is available in 8-, 16-, 32- and 48-p ort models, in a 1U rack-mount
form factor.

Adding Port Administrators and Users
The system administrator and root user can add port administrators and
additional users easily with th e web interface by choosing System
administration > User administration > Add user.
Ways to Configure the Digi CM
This section discusses the three ways to configure the Digi CM using the web
interface, configuration menu, or command line interface.
Web Interface
The web interface provides an easy way to configure the Digi CM. The root
The Digi CM web
interface features
HTTPS for secure
access.
user and system administrator can configure all featu res through the web. Port
administrators can configure ports, including port clustering, but cannot modify
system settings. No other users can use the web interface for configuration.
To access the web interface, enter the Digi CM IP address or host name in a
browser’s URL window. The following page is displayed after login.
admin admin
Chapter 1 11
Ways to Configure the Digi CM
Configuration Menu
The root user and system administrator have full access to the configuration
menu from a Telnet or SSH session or a serial connection through the console
port. Functionality is similar to the web interface, with the exception of custom
menus, which can be created only from the web interface. The configuration
menu is presented to system administrators automatically. Root users access
the menu by entering the command configmenu. Port administrators can
access this menu but can mod if y ser i al port configuratio n o nl y. No other users
can access this menu.
Command Line Interface
The command line interface can be accessed from a Telnet or SSH session or
from the console port. The root user always has access to this interface. The
12 Chapter 1
system administrator can be granted read-only permission as well. No other
users can access the command line interface.
Ways of Accessing the Digi CM: Overview
There are four wa ys to access the ports on the Digi CM:
• Web Interface
• Port Access Menu
• Direct Port Access
• Custom Menus
Web Interface Access Menu
The web interface menu provides easy and convenient access to ports. All
users can access the menu by entering the Digi CM IP address or host name
in a web browser’s URL windo w. Y ou will on ly be abl e to see the port s that you
are allowed to access.
To access a port from the web interface, do the following:
1. Access the web interface.
Introduction
2. Click Serial port > Connection.
The P (Power) col umn allo ws you to control power of the attach ed devices, if a
Remote Power Management unit is attached and you have appropriate rights.
The M (Manage) column offers web based management for Windows Server
2003, Remote Power Management units or Rackable Systems Management
Card.
The “# of User” column shows how many users are actually connected to the
port and the username of the read/write user.
Chapter 1 13
Web Interface Access Menu
If you are conducting a special task through the console port, like BIOS
upgrade and should not be interrupted, you can notify other users by entering
a comment upon connect. This comment is shown here.
3. Select a port by clicking the icon in the C (Console) column.
A Java applet or Telnet window opens with a login prompt.
The web interface can also be configured to call a local Telnet or SSH
application, see "Configuring Host Mode" on page 47.
14 Chapter 1
Port Access Menu
The Port Access Menu provides access to ports. It is accessible to all users
through the web interface, Telnet and SSH sessions, and remote modem
access. The information that follows shows you how to access this menu.

Port Escape Menu
Port escape is the ability to escape from a port without disconnecting. Port
escape is available in main session s as well as sniff sessions. Every
connection method accommodates port escape. You configure the escape
sequence per por t. Follow the procedure to configure the port escape
sequence.
