Chapter 1

Overview of the LX-4000 Series

The LX-4000 Series is a secure standalone communication server that is designed for applications
requiring secure console or serial port management. The LX-4000 Series provides the most secure and
robust feature set to meet your remote console management and terminal server needs. The LX-4000
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-4000 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-4000 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-4000 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 MRV Communications, Inc. www.mrv.com 13

Overview of the LX-4000 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.).
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.

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-4000 kit.)

Modem Port (Optional)

The modem port is a V.90/K56flex Kbps optional factory installed modem on the LX-4000 Series. The
modem port allows you to dial back from, or dial in to or out of the LX-4000. 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-4048 models, the modem port is on the
front of the unit.

The Modem port number is as follows for LX-4000 models:

• LX-4008 - port number 9

• LX-4016 - port number 17

• LX-4032 - port number 33

• LX-4048 - port number 49

At the InReach:0>> prompt, enter the show port async 33 modem command to display a screen
containing the LX-4032 modem port fields.

Powering On

The Power On Self Test (POST) starts when you apply power to the LX-4000 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 C for an explanation of the codes.
When the POST test is completed, you are presented with two options: [B] Boot System and [L]

Login to System Setup. If you choose neither, the unit boots on its own after eight seconds. If you
type L, a password prompt appears. The default password is access. The Main Menu appears after
you enter the password. The Main Menu allows you to change the boot settings and IP address
assignments. You can review the factory default boot setting by referring to the “ppciboot Factory
Default Settings” on page 50. The system loads the LX-Series software from flash and then loads the
system configuration file.

If the LX boots with default operational parameters, the Quick Configuration menu appears. Refer to
the “System Maintenance” chapter in the LX-Series Configuration Guide for further information on
the Main menu. Refer to “First Time Quick Configuration” on page 25 for further details on the Quick

Accessing and Configuring the Graphical User Interface (GUI)

IMPORTANT

If your browser is connected to an LX running an older software version, you must close
the browser completely and clear the cache before connecting your browser to an LX running a
more recent software version. This is because the Java saves the applet to your PC. If you fail to
close the browser completely, the browser will use the old applet when you connect to the
LX running a later software version, and therefore some features will be missing from the GUI
windows.

This section describes how to access and configure the LX via the GUI. To perform this procedure,
you need a PC with Java Runtime Environment (JRE) 1.4.2 or later installed.

NOTE: For optimum GUI performance, MRV recommends that your PC run at 500 MHz or better.

The minimum requirement for desktop color settings is 256.

The 4800 -48 VDC Series family of products provides easy, practical, and secure solutions for power
distribution, power management and load-measurement for remote internetworking equipment and
branch AC circuits.

4800 Series products are available in a 4-outlet configuration. An 4800 Series offers individual
remote control over the power on/off status to a maximum of four DC powered devices. The 4800
supports -48 VDC up to 70A.

The following section explains how to connect and install the 4800.

Connecting the 4800

The 4800 Series is equipped with a single RJ45 RS-232 serial port for attachment to a PC or
networked terminal server using the supplied RJ45 to RJ45 crossover cable and RJ45 to DB9F serial
port adapter as required. See the Technical Specifications in Getting Started with the MRV
Communications 4800 Power Control Series for more information on the RS-232 serial port.

Alternative Port Capabilities

To connect the 4800:

1. Connect one end of the standard RJ-45 double-ended crossover cable to the serial port of the 4800.

2. Connect the other end to any LX port you have configured as a power management port.

Alternative Port Capabilities

You must change the port’s “access” to “power model ir4800” before performing any control and
monitoring operations. Use the following command, in the Async Port Configure Mode, to
configure asynchronous port 10 as a 4800 port:

Async 1-10:0>>access power model ir4800

Once the 4800 is enabled, you can check its status with the following command:

InReach:0>> show port async 10 status

3. You can also control and monitor the 4800 remotely through the LX CLI. Refer to the LX-Series
Commands Reference Guide for a detailed explanation of the commands used to configure and

view your 4800 through the CLI interface.

Using LX Ports as Alarm Inputs and Control Outputs

The LX-Series can be configured to provide two low voltage/low current outputs per port which can be
used to control remote devices. Using the DTR and RTS signals, these are designated Control
Outputs. They can be used to control external equipment, or they may be used as the controlling
voltage for Alarm Inputs circuits.

The LX-Series can be configured to provide two signal monitor inputs per port using the DSR and
CTS signal to provide a remote device monitoring capability. These are designated Alarm Inputs. The
following sections describe the use of these signals in greater detail.

Some common terms are:

• Alarm Inputs - LX-Series port input signals DSR and CTS used in conjunction with the Signal­Notice software feature to monitor real world events.

• Alarm Points - High impedance, low current, isolated inputs available in the MRV Corporation
IR-7104 product.

• Control Outputs - LX-Series port output signals DTR and RTS managed with the Access Control
software commands that could be used to control external equipment or provide a controlling
voltage for Alarm Inputs.

• Control Relays - True SPDT (Single Pole Double Throw) “Form C” Relay contact points
available in the MRV Corporation IR-7104 product.

Alarm Inputs Setup and Usage

The LX-Series can be configured to provide two Alarm Inputs per port using the DSR and CTS
signals. These are enabled with the Signal-Notice feature. Signal-Notice utilizes sets of Trigger-
Action-Rule commands to detect contact closure/opens. The contacts you are monitoring may be
located within your facility, for example doors alarms, window alarms or fluid level sensors. The
contacts may also be contained within your equipment you wish to monitor, for example equipment
fault alarms, temperature alarms and other error condition signals. The signaling device may be a
simple electro-mechanical device such as a switch, a magnetic contact or a relay. The signaling device
may also be electrical such as an opto-isolator, a CMOS driver or a transistor circuit. Typical circuits
are illustrated in Figure 20.

42

MRV Communications, Inc. www.mrv.com 451-0308

Alternative Port Capabilities

Alarm Inputs use the LX-Series input circuits (DSR and CTS) to detect level transitions. These input
circuits sit at the 0V level when left unconnected and can accept a voltage input in the range of ±10V.

Figure 20 - Typical Alarm Inputs Connections

An external voltage within the range of ±10V is required in order for a change to be detected when the
contact opens or closes. Typically, an LX-Series Control Output is used to provide the controlling
voltage for the Alarm Inputs, but it is not required. An external voltage could be used as long as it is
within both the ±10V limits and the limits of the contacts or semiconductor used in the circuit. A
common Signal Ground is required. Refer to Figure 20 for typical implementations.

Important design issues to remember are:

• Electro-mechanical contacts must be rated up to 10V and 3.5mA.

• The inputs present a nominal 5K Ohm impedance but can vary from 3K to 7K Ohm.

• Input levels must be 0.6V or lower to guarantee a low state and 2.4V or higher to guarantee a
high state.

• LX-Series products do not support the use of TXD as the controlling voltage for Alarm Inputs.
DTR or RTS must be used.

• DTR or RTS can provide the controlling voltage for up to 2 Alarm Inputs each.

• A common Signal Ground is required. Twisted pair connections are recommended to reduce
sensitivity to noise.

Note that provisions for handling alarm contact bounce and alarm flooding are available in the IR­7104 Alarm Manager family only.

Control Output Setup and Usage

The LX-Series can be configured to provide two low voltage/low current Control Outputs per port
using the DTR and RTS output signals. Typically the Control Output is used as the controlling
voltage for the LX-Series Alarm Inputs. In another case you can design an interface to transition
from the output signals to a higher capacity circuit to implement a control subsystem. An example
circuit is shown in Figure 21.

Important design issues to remember are:

• Special design attention is required when using Control Outputs in a control subsystem.

• Upon a restart or power up the states of DTR and RTS will transition several times as the LX­Series begins its start-up initialization.

451-0308 MRV Communications, Inc. www.mrv.com 43

Alternative Port Capabilities

• The states are undefined upwards of 30 Seconds + the Boot Delay Timer value in some
configurations, i.e. the signals are non-latching through power cycles.

• Note that negative voltage could be present on the interface until the software is completely
initialized.

• Control Outputs in the LX-Series guarantee ±5.0V drive into a 3K Ohm load.

• External loading below 3K Ohm can be tolerated but under no circumstances should the device
load the LX-Series output below ±2.5V/7.6mA absolute maximum drive.

• A common Signal Ground is required.

• The MRV Corporation IR-7104 family can provide true Form C SPDT Relay outputs rated to
30VDC/1A per contact if higher capacity and stable contacts are required through restart and
power cycles.

Figure 21 - Typical Interface Design for Control Output Signals

You must change the LX-Series port access type to control to utilize DTR and RTS as the Control
Outputs. For example:

InReach:0>> config port async # access control

If you want the DTR signal to be asserted High (positive voltage) on the port:

InReach:0>> control port async # dtr high

Refer to the LX-Series Configuration Guide for a detailed explanation of the commands to set up a
port in the Control function.

POST Test Error Code Sample

Appendix C - POST Test Error Codes

NOTE: This example applies to 8, 16, 32, and 48 port LX units. The 16, 32, and 48 port

LX units use only the first eight LEDs when generating error codes.

The following sample illustrates the Port Status LED sequence for Error 2030 (Reading Invalid Value
from PLD System Fail Status Register) on the LX-4008. In this example:

1. A POST test failure occurs on an 8-port unit. All LEDs flash eight times, very quickly, then the error code
is displayed.

2. You record that LED 3 turns on. Again, all LEDs flash eight times very quickly, then the rest of the error
code is displayed.

3. You record that LEDs 3 and 4 turn on. Figure 22 explains how to interpret the sample error code.

NOTE: In hexadecimal, 0 indicates the LED is OFF. 1 indicates the LED is ON.

Each group of four LEDs is converted to a hexadecimal value as follows:

• 0 = 0000

• 1 = 0001

• 2 = 0010

• 3 = 0011

• 4 = 0100

• 5 = 0101

• 6 = 0110

• 7 = 0111

Cabling Considerations

Standard cabling items available from MRV 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 cable (crossover cable for

connecting to a DTE (Data Terminal Equipment) device, straight-through cable for connecting to a
DCE (Data Communication Equipment) device), and the correct modular adapter (male or female DB­25 connector), which is essentially an RJ-45-to-DB25 adapter.

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-4000 once the unit completes the bootstrap process.

Modem Control/Hardware Flow Control

LX-4000 Series serial ports can be set up to support RTS/CTS flow control. The adapters shown in
Figure 27 and Figure 28 illustrate RTS/CTS flow control for DTE devices using DB25 and DB9
connectors. Figure 29 illustrates RTS/CTS flow control for a DB-25 connector on a DCE device like a
modem. LX-4000 Series serial ports can also be set up to support modem control (except for the DIAG
port (port 0)). Figure 27, Figure 28, and Figure 29 support modem control as needed. Only Figure 28
and Figure 29 support concurrent modem control and RTS/CTS flow control between the LX-4000
Serial Port and the attached device.

The adapter shown in Figure 29 supports modem control.

58

MRV Communications, Inc. www.mrv.com 451-0308

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

You should give special consideration to the wiring scheme when connecting a device such as a
terminal to a LX-4000 Series serial port. The LX-4000 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 27 and
Figure 28. When a DCE device is connected to an LX-4000 Series serial port, straight-through wiring
is required, as shown in Figure 29.

NOTE: In general, an ethernet category 3 (CAT 3) or category 5 (CAT 5) 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. These adapters direct
signals from the RJ-45 connector on the cable to the correct pin on the DB-25 connector. Figure 27,
Figure 28, and Figure 29 show how devices are cabled when you use these adapters.

Application (see Figure 27): Use RJ-45 to DB-25 to connect your LX-Series unit to a PC.

NOTE: In order to expand the functionality of the serial interface, the LX-4000 Series modular

cabling allows you to connect different signals to pin 7 of the LX-4000 Series. (This pin is an
input to the LX-4000 Series.) When a DCE device is connected to an LX-4000 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-4000 Series serial port, the device's DTR output is
connected to pin 7 of the LX-4000 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 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.

In Figure 31, 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:

451-0308 MRV Communications, Inc. www.mrv.com 61

Appendix D - Cabling the LX-4000 Series

• 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.

Application (see Figure 31): Use RTS/CTS to connect your LX-Series unit to a modem.
