Chapter 1
Overview of the LX-8000 Series
The new LX-8000 Series brings dual power to the LX-Series line. The LX-8000 Series is a secure
standalone communication server that is designed for applications requiring secure console or serial
port management in environments requiring high-reliability and/or dual power. The LX-8000 Series
provides the most secure and robust feature set to meet your remote console management and
terminal server needs. The LX-8000 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-8000 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-8000 Series is available in two base models: the 20-port LX-8020S and the 40-port LX-8040S,
each with single or dual AC power supplies or dual DC power supplies and an optional internal
modem. The LX-8000 Series also provides 20- and 40-port densities of RS-232 DTE RJ45 Serial ports,
as well as V.90/K56 flex Internal Modem options. The LX-8000 Series is specifically designed for
applications requiring secure console or serial port management with optimal performance, security,
and reliability.
The LX-8000S models are designed for telco applications that demand high quality and reliability
standards, dual power, and NEBS Level-3 Certification. The LX-8000 dual DC powered units are
NEBS Level-3 compliant.
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 LX-8000 Series
14 MRV Communications, Inc. www.mrv.com 451-0331
•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, 0is 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.
•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.

Installing the LX-8000 Series
Port Status LEDs
Each of the 20 (or 40) 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.
FLT/SYS
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/SYS
Solid green indicates the system’s voltages are normal and the unit has passed the POST test. Red
indicates the POST test has failed.
A and B FEED
NOTE: On non-redundant systems, the B feed will be off.
This LED turns green when a cable is plugged into the A or B side of the AC or DC feed and power is
present (the range is 90V to 230V). The B side is present only on redundant systems. The FEED LEDs
only indicate whether or not power is present at each input connector. The LED turns red when power
is lost on the A or B side of the AC or DC feed.
A and B REG
NOTE: On non-redundant systems, the B REG will be off.
NOTE: If the Aor B FEED LED is red, the Aor B(depending on which side) REG LED will also
be red.
This LED turns green when the A or B regulation power input to the board is functioning within
tolerance. It turns red when the internal power supply is malfunctioning or outside specifications
(this indicates that one of the internal power supplies within the unit is malfunctioning, or not
receiving input power).
TEMP
This LED turns green when the system temperature is within limits. It turns red when the system
temperature exceeds the limits. A maximum of 600C (140F) and a minimum of 00C (32F) is the
default.

RCV
The RCV LED is one of two integral LEDs on the 10/100 jack. This yellow LED flashes to
indicate receive activity on the link.
LINK
This green LED defaults to a link good indicator. If the link is present and operating, the
LED comes ON.
Environmental and Installation Considerations
• Unit must be installed in an environment with 5% to 90% humidity, noncondensing, 0° -
40° C (32°-104° F).
• Do not choose a location where the unit will be exposed to direct sunlight or subjected to
vibration.
• Do not place an object on the side(s) of the unit that might block airflow through the unit.
• The unit may be front, rear, or center mounted.
• There is no mounting difference between the 19” and 23” rack mount ears.
Mounting the Unit into a 19-inch or 23-inch Rack
Attach the brackets to the unit, and then mount the unit in the rack. Refer to Figure 6 for further
information.
Figure 6 - Mounting an LX-8000 Series in Rack

20 MRV Communications, Inc. www.mrv.com 451-0331
Cable Connections
This section explains the cable connections for the LX-8000 unit.
Connect the Power Cable
Connect the supplied power cable to the rear of the LX-8000 unit and plug the other end into a 3-
prong wall outlet.
Connecting the Ethernet Interface
NOTE: The LX-8000 Ethernet ports support the MDI/MDIX feature that allows you to use straight-
through or crossover cabling. For MDIX to function, port speed and duplex must be set to
auto.
NOTE: This port is set to auto negotiation by default. You can manually configure the port speed
and duplex if you want. Refer to the LX-Series Commands Reference Guide for further
details.
Connect a category 3 (CAT 3) cable for 10 Mbps operation, or a category 5 (CAT 5) cable for 10/100
Mbps operation to the 10/100 connector(s) on the rear of the LX-8000 Series (see Figure 3) and the
other end to your network. The LINK LED comes on steady green if the cable is properly connected.
Connect Serial Device Cables
Connect the serial device cables to the 8-pin RJ-45 jacks on the rear of the unit.
NOTE: LX-8000 Series serial ports provide concurrent support for RTS/CTS flow control and
modem control. Refer to Appendix A and Appendix D for further information.
Connecting Your Management Station
Connect the management station to the DIAG port (port 0) using the connector and cable you
received with the LX-8000 unit. Refer to “Connecting to the Diagnostic Port (Port 0)” in
Appendix D for more information on DIAG port connections.
