Chapter 1
Overview of the LX Series
The LX Series is a secure standalone communication server that is
designed for applications requiring secure console or serial port
management. The LX Series provides the most secure and robust feature
set to meet your remote console management and terminal server needs.
The LX Series includes the most comprehensive security features, such as
per port access protection, RADIUS, Secure Shell v2.0, PPP PAP/CHAP,
PPP dial-back, on-board database, menus, and others.
The LX Series 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.
The LX Series also provides various port densities of RS-232 DTE RJ45
Serial ports, as well as V.90/K56 flex Internal Modem options. Currently,
the LX hardware provides port densities of 8, 16, 32, and 48 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 0 represents the session number.

Overview of the LX Series
14 451-0308
•Configure Mode prompt – A sample configure mode prompt is
Async 1-6:0 >>, where Async is a reminder that tells you which part
of the configuration you are in, 1-6 is the range of ports any operation
will affect, 0 is a session number, and >> indicates superuser mode. To
get to the Async 1-6:0 >> prompt, you must first type port async
1 6 at the Config:0 >> prompt. Note that you do not add a dash
between the range numbers in port async 1 6.
•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.
NOTE: You must press the Enter key after you type Ctrl-F, Ctrl-B,
or Ctrl-L.

FLT
Solid red indicates a fault condition exists or maintenance is required. This
LED remains on until the initial Power On Self Test (POST) completes
successfully.
OK
Solid green indicates the system’s voltages are normal and the unit has
passed the POST test.
Port Status LEDs
Each of the eight (or 16, or 32, or 48) green LEDs flash when receive,
transmit, or status activity is detected on its corresponding serial port. The
port status LEDs are used in several ways. During the initialization process,
the LEDs indicate self-tests are being performed, and if any self-test fails,
they indicate an error code. After a POST test and a system software boot, the
lights indicate when a port is actively being used.
Rear Panel LEDs
This section explains the rear panel LEDs and shows you a rear view of the
various LX models (see Figures 5 through 11).
