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.
451-0308
13
Page 14
Overview of the LX Series
• 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.).
14
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.
451-0308

Figure 13 - Connecting DC Power
After you have installed the LX unit, you can connect the DC power as
described in the following procedure (refer to Figure 13):
1. Connect the LX to the facility's bonding network, using the points on
the rear panel of the LX. The connection to the facility's bonding
network should be made per local practices, using wire with a
minimum conductor size of 18 AWG.
2. Using a ¼-inch nut driver, remove the terminal block nuts.
3. Attach the facility’s “A” feed to the terminal block labeled “A”.
NOTE: Be sure that the -48VDC is connected to the minus side, and the
48VDC return is connected to the plus side.
4. Attach the facility’s “B” feed to the terminal block labeled “B”.
5. Replace the nuts and tighten them securely.
26
The DC leads should be 22 AWG or larger. They should be terminated
with a #5 ring terminal or larger depending on the wire size used.
451-0308
Page 27
NOTE: The LX will run with only one DC power feed connected. The
second input is provided for redundant system power, which is
used in high reliability installations.
6. Attach the clear plastic safety guard to the terminal blocks. (The clear
plastic safety guard is provided with the LX kit.)
Modem Port (Optional)
The modem port is a V.90/K56flex Kbps optional factory installed modem on
the LX Series. The modem port allows you to dial in to or out of the LX. If the
modem is present, connect your phone line to the modem’s RJ11 connector. If
the modem is not installed, the RJ11 connector will not be present on the rear
of the unit. In LX-4048M models, the modem port is on the front of the unit.
The Modem port number is as follows for LX models:
•LX-4008M - port number 9
•LX-4016M - port number 17
•LX-4032M - port number 33
Installing the LX Series
•LX-4048M - port number 49
At the InReach:0>> prompt, enter the show port async 33 modem
command to display a screen containing the LX-4032M modem port fields.
Powering On
The Power On Self Test (POST) starts when you apply power to the LX Series
unit. The port status LEDs flicker and the FLT LED remains on while the test
is running (this may take only a few seconds). If the unit passes the POST
test, the FLT LED extinguishes, and the OK LED turns green. If there is a
failure, the FLT LED stays on, and the port status LEDs begin flashing an
error code. Refer to Appendix B for an explanation of the codes.
451-0308

Reference Guide, and to the Support area of the MRV website at
www.mrv.com.
Sensor (Temperature/Humidity) Ports
You can configure ports to act as temperature and humidity monitors when
connected to an In-Reach Temperature/Humidity Sensor. The Temperature/
Humidity Sensor provides an accurate measurement of the temperature/
humidity in the area in which your LX Series unit is placed.
The following section explains how to connect and install the sensor.
Connecting the Temperature/Humidity Sensor
A 10’ Male RJ-45 to Male RJ-45 straight-through cable (P/N MX-151-3027)
connects the temperature/humidity sensor to an LX async port. The LX
unit can be configured to support the sensor on any async port other than
the DIAG port (port 0).

Cabling Considerations
Standard cabling items available from MRV Communications allow you to
connect to any serial device that uses male or female DB-25 or DB-9
connectors. All you need is the appropriate modular cable (crossover cable
for connecting to a DTE device, straight-through cable for connecting to a
DCE device), and the correct modular adapter (male or female DB-25
connector), which is essentially an RJ-45-to-DB25 adapter.
Serial Device Connectors

Ordering and Installing the Inlet Connector Lock
You can use an inlet connector lock to lock the AC power cord to the LX
Series unit. MRV Communications does not supply this lock. You can order
the connector lock (part number 85910020) from Panel Components
Corporation. The web address at which you can order the connector lock is:
www.panelcomponents.com/first.html. See Figure 21 for installation
instructions.

Connecting to the Diagnostic Port (Port 0)
NOTE: Display problems may occur during bootup when you attach a
VT420 terminal to the DIAG port (port 0) and the VT420 display
setup is configured to Smooth-2 Scroll. To avoid this, change
the VT420 scroll setting to Jump Scroll.
Connect the provided serial port cable to the DIAG connector (port 0), and
the other end to your terminal. You can use this direct connect serial link
to send commands to the boot loader and diagnostics. This port is used to
log system messages during bootup. You can also use port 0 to manage and
configure the LX once the unit completes the bootstrap process.

Modem Control/Hardware Flow Control
LX Series serial ports can be set up to support RTS/CTS flow control. The
adapters shown in Figure 22 and Figure 23 illustrate RTS/CTS flow
control for DTE devices using DB25 and DB9 connectors. Figure 24
illustrates RTS/CTS flow control for a DB-25 connector on a DCE device
like a modem. LX Series serial ports can also be set up to support modem
control (except for the DIAG port (port 0)). Figures 22, 23, and 24 support
modem control as needed. Only Figures 23 and 24 support concurrent
modem control and RTS/CTS flow control between the LX Serial Port and
the attached device.
The adapter shown in Figure 24 supports modem control.
NOTE: You would use a "null-modem" cable when making a direct
connection between the serial ports of two communication servers
(i.e., no modems involved) or other DTE device. For that
application, use a DTE-to-DTE cable.
RJ-45 Wiring Considerations
60
You should give special consideration to the wiring scheme when
connecting a device such as a terminal to a LX Series serial port. The LX
Series is considered a DTE device. To connect to another DTE device such
as a terminal, you will need crossover wiring, as shown in Figure 22 and
Figure 23. When a DCE device is connected to an LX Series serial port,
straight-through wiring is required, as shown in Figure 24.
NOTE: In general, an ethernet CAT3/CAT5 may introduce noise due to the
crossing of pins 3 and 6 (transmit and receive). Flat eight wire
cables are recommended.

Modular Adapters (RJ-45 to DB-25)
You can obtain adapters with male and female DB-25 connectors from
MRV Communications. These adapters direct signals from the RJ-45
connector on the cable to the correct pin on the DB-25 connector. Figure 22,
Figure 23, and Figure 24 show how devices are cabled when you use these
adapters.

Cabling the LX Series
NOTE: In order to expand the functionality of the serial interface, the LX
Series modular cabling allows you to connect different signals to
pin 7 of the LX Series. (This pin is an input to the LX Series.) When
a DCE device is connected to an LX Series serial port, the device's
DCD output is connected to pin 7. In this case, the signal at pin 7 is
referred to as DCD. DCD is used here for session control only, not
for flow control.
When a DTE device is connected to an LX Series serial port, the
device's DTR output is connected to pin 7 of the LX Series. In this
case, the signal at pin 7 is referred to as DSR. (This cabling scheme
also provides DECconnect compatibility, since DECconnect does
not support the DCD signal.)
MRV Communications 8-Wire Cabling
This cabling scheme provides XMT, RCV, DCD/DSR, DTR, RTS, CTS, and
two signal ground wires. This cabling is provided through RJ-45
connectors. Using this cabling scheme you can concurrently use modem
control and RTS/CTS hardware flow control, since there are four control
signals. This scheme is useful with relatively high speed devices, complex
modem control applications.
64
In Figure 25, one signal is referred to as CTS. The CTS signal designation
refers to the signal observed at pin 1 of each serial port. Pin 1 is
multiplexed to these signals.
This scheme is useful with the following applications:
•Terminal emulation and file transfer applications, such as Kermit,
Xmodem, Microphone, etc.
•Applications such as PPP using low speed modems.
•Applications such as PPP using high speed modems.
•Applications using CCITT V.42-compliant modems, or other devices
operating at high port speeds.
