Chapter 1
Overview of the EM316LX
The EM316LX is a secure chassis card communication server that is designed for applications
requiring secure console or serial port management. The EM316LX provides the most secure and
robust feature set to meet your remote console management and terminal server needs. The
EM316LX includes the most comprehensive security features, such as per port access protection,
RADIUS, LDAP, Secure Shell v2.0, PPP PAP/CHAP, dial-back, on-board database, menus, and
others.
The EM316LX console management solution enables centrally located or remote personnel to connect
to the console or craft ports of any network element or server. This serial connection allows
administrators to manage and configure the remote network devices and servers, as well as perform
software upgrades as if attached locally.
Currently, the EM316LX hardware provides port densities of 1 serial port plus a V.90/K56 flex
Internal modem plus port 0 for local management, or 2 async serial ports plus port 0 for local
management.
Conventions
The following conventions are used throughout this guide:
•User prompt – The user prompt is (for example) InReach:0> for Non-superusers or InReach:0>> for
superusers. The prompt will change based on a login user profile, as configured by the Superuser.
The 0represents the session number.

Overview of the EM316LX
16 451-0330
•Configure Mode prompt –A sample configure mode prompt is Async 1-2:0 >>, where Async
is a reminder that tells you which part of the configuration you are in, 1-2 is the range of ports
any operation will affect, 0is a session number, and >> indicates superuser mode. To get to the
Async 1-2:0 >> prompt, you must first type port async 1 2 at the Config:0 >> prompt.
Note that you do not add a dash between the range numbers in port async 1 2.
•Command execution – Unless otherwise specified, commands are executed when you press
<RETURN>.
•Keyboard characters (keys) – Keyboard characters are represented using left and right angle
brackets (< and >). For example, the notation <CTRL> refers to the CTRL key; <A> refers to the
letter A; and <Enter> refers to the RETURN key.
•Typographical conventions – The following typographical conventions are used:
Monospace Typeface – indicates text that can be displayed or typed at a terminal (i.e.,
displays, user input, messages, prompts, etc.).
Italics – are used to indicate variables in command syntax descriptions.
•Help Key (?) - At any prompt level, you can press ?to display the available commands at that
level. The only time this is not true is if you are in the midst of entering a command. If ?is at the
end of a partial command, the LX displays a list of valid arguments to assist you in adding to the
current command line.
•Tab - Press the Tab button to complete a partially entered command. You must enter the first
three characters of a command for autocomplete to work. If the command is already complete, the
Tab button displays available commands.
•Command Recall - The up arrow recalls previously used commands.
•Ctrl-F – Moves forward to the next session.
•Ctrl-B – Moves back to the previous session.
•Ctrl-L – Returns you to the Local Command Mode.
•Ctrl-K –Clears the current command line.
NOTE: You must press the Enter key after you type Ctrl-F, Ctrl-B, Ctrl-L, or Ctrl-K.
