Fig. 1 Rear View of original Console Server 3200 - notice Control Card to far right

The SCS3230 upgrade replaces the CONTROL card of the 3200 with a new 10/100 BaseT
NETWORK and CONTROL card which includes a Linux-based operating system, and also
replaces the NETWORK and TERMINAL cards of the 3200 with CHANNEL EXTENDER cards.

1.1 Quick Start

Overview of Upgrading from a CS3200 to a SCS3230 (all covered in this manual):

1. Backup the Database of your existing CS3200 System.

2. Obtain the SCS3230 Kit, which includes the cards, cables and this manual.

3. Locate the firmware updates for the DEVICE cards; they are stored in the /lci/bin
directory on the NETWORK/CONTROL card. You may also download the update files
from the Lightwave FTP site. DEVICE cards MUST be updates to Version 4.03 firmware.

4. Remove the CS3200 from service.

5. Remove the CONTROL card, the TERMINAL card(s) and the Network or 10/100 card(s)

6. Install the 3230's NETWORK/CONTROL card in place of the CONTROL card.

7. Install the four CHANNEL EXTENDERS in place of the TERMINAL or NETWORK cards.

8. Connect the four cables for the CHANNEL EXTENDERS.

9. Turn the System On, and administer the system using the TERM port. Set up your IP
network connection information to get that operating.

10. RESTORE your CS3200's database into the SCS3230 system.

The SCS3230 system should be fully operational at this point.

1.3 System Features

The SCS3230 system is a Linux-based Console Server offering secure IP network -based
connections to up to 32 connect ed devices via EIA-232 protocol. Linux administrators will find
familiar commands and should need little guidance on administering the SCS3230 to co -operate
in their server installation.

System users will not encounter any differences in operation. The commands and functions of
the SCS3230 are designed to minimize any conversion issues.

The SCS3230 offers the following important features (many of which are also found in the
CS3200 product):

• Hot-Swappable cards

• Dual Redundant Power Supplies

• 10/100 IP Network Interface

• Connect up to 32 RS-232 serial devices

• ID / Password Security, configurable access rights

• OpenSSH version 2 security

• Open LDAP

• NIS capable for remote database rights

• No unintentional break will ever be sent to attached servers

• Local access through TERM port (the 3230's Console port)

• Field upgradeable Flash memory

• User programming interface for simple administration and setup

Rev. A - 10 - www.lightwavecom.com

A Lantronix Company SCS3230 System Administrator's Guide

1.4 Hardware Features

• 3RU tall (5-1/4 inches) rack -mountable Server

• One (1) 10/100 baseT Network Port for connection to your IP network

• Up to 32 serial DEVICE ports, RS232, connected via Category 5 (RJ45) wiring

• One (1) serial TERMINAL port, for VT100 console or PC with emulation

• 128KB-per-port Buffer Memory for DEVICE ports

• Front Panel multi-line backlit LCD display and pushbutton controls

• 128MB FLASH Memory, 128MB RAM

• * Redundant Power Inputs (chassis dependant)

• Optional Analog Modem for dial up access (non-secure)

• Power Options: Universal AC (100-240V) or -48VDC

* Some early CS3200 Chassis employ a single AC Power Input module. The Power Module is
field-replaceable to provide redundant power capabilities, if required.

The SCS3230 is one of the most versatile network administration tools available today,
allowing as many as 17 simultaneous users to access up to 32 connected devices via
the RS-232C serial protocol. Pull -down menus help users navigate through all the
functions of the SCS3230, creating an easy-to-use way to access system resources.

The SCS3230 consists of eight device card slots, two switch card slots, four access card slots,
one modem slot and one Network/Control slot. The power supply slot contains two independent
power supplies for redundant operation. The basic system consists of the power supply
module, two switch cards, the Network / Control card, and in most cases, four Channel Extender
Cards. The remaining card slots are populated according to the application requirements.

All system parameters are stored in non-volatile data flash memory. This data flash memory is
organized such that there is always a complete copy of all data. Typical stored information
includes the users’ identities, user passwords, port parameters (such as baud rate, device
name, etc.) and other system information. The data flash memory allow for a maximum of 200
user profiles to be stored, along with the parameters for all cards. System parameters may be
backed up and restored from a local serial connection.

An important feature of the SCS3230 is the ability to re-configure the system hardware and
software without turning off the power. The system boards have circuitry that allows them to be
'hot swapped' so the system may be expanded at any time while in use.

System updates can be accomplished via software upload to the system. For most updates, the
system need not be restarted or taken out of service. Some operations or updates (e.g.,
Network update) may require the network ports be restarted.

"unused"; and this unnecessary cable would not be installed in that position.

1.5.1 10/100 Port (Network)

The 10/100 BaseT Network connection is accessible on the bottom RJ45 connector on the
NETWORK / CONTROL card.

Rev. A - 14 - www.lightwavecom.com

A Lantronix Company SCS3230 System Administrator's Guide

1.5.2 TERM Port (Console)

A Terminal port, or Console (labeled TERM) is available at the top RJ45 connector on the
NETWORK / CONTROL Card. This is an EIA -232-compliant terminal position, typically used for
System Administration purposes.

The TERM port on the NETWORK/CONTROL card is fixed at 9600 baud, 8 data bits, No Parity,
and one Stop bit (9600 / 8 / N / 1) and is a DCE device.The TERM port has a higher Terminal
priority than the 10/100 Network Port on this card, and can be used for forced logout of
abandoned or other undesirable connections.

1.6 Backup and Restore Commands

The SCS3230 system is fully compatible with the "Backup and Restore" capabilities of the
CS3200, so transferring your user database from your existing CS3200 into the new SCS3200
hardware is supported.

ConsoleServer 3200 System Lightwave Communications

2: System Overview

For simplicity, we will discuss the features and capabilities of the SCS3230 as if it were a new
and different system, not merely an upgrade to a ConsoleServer 3200. The SCS3230 is
designed to operate as closely to the original ConsoleServer3200 as possible from a user's
perspective, but still provide the capabilities needed for the secure server environment.

Existing 3200 customers maintain their investment and can offer enhanced security and control
for their terminal server systems. Existing users will not require retraining since all commands
and features of the SCS3230 option are the same as found in the CS3200. Even the upgrade
process accepts the existing site database for rapid deployment of the SCS3230 equipment.

2.1 Connect Up to Thirty-two RS-232C Compatible Ports

The SCS3230 is plug-compatible with any RS-232C device , DTE or DCE. These include a
variety of network servers, routers, or any other LAN/WAN computers on the network.
Connections are made by routing the device signals through the switch cards to the appropriate
user interface port.

2.2 128K FIFO Audit Trail

The SCS3230 stores the equivalent of approximately 200 screens worth of data (128K) per
device port in a true FIFO buffer for each DEVICE port. This data may be viewed 'off-line' at
any time by users accessing the device port buffer.

Should more than 128K of data be received in a buffer, the oldest data will be discarded, in the
amount of the 'overflow'. By operating in this fashion, the most recent data is collected and the
largest amount of data that can be saved will be maintained.

2.3 Connections

The system is capable of 17 simultaneous full-duplex connect ions to the connected devices.
The administration functions may be accessed through a local serial connection or through a
network connection. The NETWORK / CONTROL card (with a full complement of four Channel
Extender cards) supports up to 16 users connections plus one connection to the administration
functions. The NETWORK / CONTROL card also provides one TERM port (for a System
Administrator's serial Console)

The TERMINAL cards (a 3200 access card) may be used for applications requiring additional
local serial terminals. Each Terminal Card is installed in place of one of the Channel Extender

Rev. A - 16 - www.lightwavecom.com

A Lantronix Company SCS3230 System Administrator's Guide

cards. By reducing the number of Channel Extender ports, the maximum number of available
connections for 10/100 network access is reduced by four sessions for each Terminal Card
installed. Illustrations showing a mixture of Channel Extender cards and Terminal Cards are
found on pages 11 and 16 of this Guide.

An optional MODEM connection is also available, however its connections are not 'secure' and
its use is not recommended except in those instances when security will not be compromised by
dial-in access using the modem. The SCS3230's modem connection is not subject to the Linux
security controls of the other access ports.

2.4 Security Passwords

The System Administrator may define up to 200 user profiles. Each user is assigned a unique
password by the system administrator. The system forces the user to change the password the
first time the user attempts to connect to any servers. After the users have changed their
passwords, the system will not prompt for a change. The users change their passwords at
whatever interval they feel is necessary.

The operating system is subject to Linux security constraints, including sysadmin and root level
security. Users cannot access the sysadmin layer or the root layer of the system.

2.5 Interface

Interfaces to the DEVICE and TERMINAL cards are all RS-232C compliant. These ports are
configured through the TERM port on the NETWORK / CONTROL card using a local Console,
or via network connection through your TCP/IP network. All system access is password
protected.

Each DEVICE port and TERMINAL has settings for baud rate, stop bits, parity, number of data
bits, flow control, and port type (i.e., DTE or DCE). The TERM port (for your Console) on the
NETWORK / CONTROL card has a fixed data format of 9600 / 8/ N / 1, and DCE.

The NETWORK / CONTROL card connects over a network using TCP/IP on 10- or 100-baseT
at 10/100 Mbits (auto-negotiating). The 10/100 port on this card is assigned an IP address, a
subnet mask, a default gateway, and an optional secondary destination path by Conso le
configuration using the TERM port on this card during the initial setup of the system.

The optional MODEM card connects directly to a conventional modular phone jack (RJ11) to
interface with a telephone network. The sys admin may designate a modem initialization string,
or may use the default modem initialization string, which allows auto-answering on one ring. The
modem provides card-edge visual status indicators.

Note: For 'secure' installations, the Modem should not be used . Modem access is not
encrypted and/or secure and could allow unauthorized access to system information. However,

if modem access is limited to internal administrative access, the modem may provide an
additional means of system access in the event your network is down.

3: System Components

Each SCS3230 consists of three major components: the 3200 system chassis, 3200 DEVICE
cards, and 3200 access cards. The 'access cards' include the new 3230 NETWORK/CONTROL
card, which is the heart of the SCS3230 product, and makes it operate a bit differently.

Note: The 3200's NETWORK card and 10/100 Network card are NOT supported by the
SCS3230 NETWORK / CONTROL card. The NETWORK/CONTROL card incorporates its own
10/100 Network port.

3.1 3200 Chassis

The chassis contains a front-panel LCD for quick system information that is available at all
times. Two front panel buttons allow display selection and paging through displays (see
section 10.0 for more information).

The second major component of the chassis is the power supply module. This module contains
two independent supplies, each capable of sustaining the system should one supply fail or lose
its power input. The Power Supply module also incorporates the system fan. The AC power
module has two front-panel switches (one for each supply) with replaceable fuses in their IEC­type connectors. The DC power module provides a single On/Off switch.

The third and last component of the chassis is the SWITCH card set. The switch cards connect
the access cards to the device cards, with a maximum of 17 simultaneous connections using all
available terminal, network, and modem ports.

3.1.1 Power Supply Module

The SCS3230 may be equipped with either an AC power module or a DC power module. The
power module may be field-swapped (although is not hot-swappable) if the available power
source requirements change.

The Power Module provides two discrete electrical inputs to the system. Either power input
supports a fully-loaded chassis, and switching between power inputs is automatic if one source
fails or is turned off.

3.1.2 3200 Switch Cards

Two 3200 SWITCH Cards are required, and are unchanged from the 3200 system.

3.2 Device Cards

The Device cards are fully compatible with the SCS3230 application. The SCS3230 requires
version 4.03 Build 01 (or higher) of the Device Card binary firmware. Firmware updates are

downloadable from the Lightwave FTP site (ftp://ftp.lightwavecom.com).

Note: DEVICE CARD firmware MUST be updated to 4.03 or higher

Each DEVICE card has four completely independent ports for attachment to servers or other
devices with console ports. Eight device cards may be installed per system, for a maximum of
32 device ports. The device ports do not send an 'break' signal to the attached servers at any
time unless specified by the user. There are no adjustments directly on the device cards. All
parameters are set up through the system administrator port.

3.3 Access Cards

The card configuration is changed with the SCS3230, compared to CS3200.

3.3.1 NETWORK / CONTROL Card

The NETWORK / CONTROL card allows
users to connect to the device cards from
an SSH or telnet session over an IP

network, and remote access to the
administration functions.

The NETWORK / CONTROL card
replaces the CONTROL card from the
CS3200, and is located in the far right slot
of the system chassis. Only one card is
required in an SCS3230.

The NETWORK / CONTROL card
includes one TERM connector for a local
Console; one 10/100 NET connector for a

TCP/IP network interface, and four
CHANNEL EXTENDER ports. The

Channel Extender ports are connected by
RJ45 cables to one to four CHANNEL
EXTENDER cards, which are an
extension of the NETWORK card's
operation.

The NETWORK / CONTROL card
supports up to sixteen simultaneous user
telnet connections and one administrator connection to the same IP address. The network card
must be connected to a network that uses TCP/IP.

15.00.038 - 19 - May 2002

ConsoleServer 3200 System Lightwave Communications

3.3.2 CHANNEL EXTENDER Cards

CHANNEL EXTENDER cards are used to extend the NETWORK functionality of the

NETWORK / CONTROL card, providing network access to the DEVICE ports in the system.
The Channel Extenders provide additional circuits allowing more simultaneous network
sessions, up to the system capacity of 16 device sessions. Channel Extenders are installed in
slots B, C, D, and slot E, replacing the N ETWORK cards and the TERMINAL cards in a 3200
system.

The SCS3230 is normally configured with four CHANNEL EXTENDERS, but may have any
combination of CHANNEL EXTENDER cards and TERMINAL cards, as required for your
application.

Note: At least one Channe l Extender card is required if any DEVICE access is required using
your IP Network.

CHANNEL EXTENDER cards connect to the NETWORK / CONTROL card using a short RJ45
cable. Each CHANNEL EXTENDER provides up to four (4) simultaneous sessions for DEVICE
port access over the IP Network connection.

3.3.3 TERMINAL Cards

The TERMINAL card provides a point of connection for a conventional RS-232 terminal or a
computer running a terminal emulation program. Users connected through a TERMINAL card
may connect to any of the device cards in the system, provided that their user profile has
access rights for the port. There are four ports per terminal card. Each port‘s parameters are set
up independently from the other ports. All parameters are set up through the system

administrator port. There is no access to the administration functions through the terminal card.
The SCS3230 may have up to 3 Terminal cards, depending on system requirements. In some

applications, the existing Terminal Card may be required for local serial connection to one of the
Device Ports. The existing Terminal Card is compatible and may be used, however the use of
each Terminal Card(s) reduces the number of simultaneous Network connections (by 4

sessions) that may be made over the new 10/100 N etwork port on the Network Control Card.
The 3200 Terminal cards offer configurable port parameters (baud rate, DTE/DCE, etc.), unlike
the fixed parameters of the TERM (Console) port on the NETWORK / CONTROL card.

The SCS3230 requires version 4.00 (or higher) of the Terminal Card binary firmware (fterm.bin).
This is not specific to 3230, and has been available for some time. Firmware updates are
downloadable from the Lightwave FTP site (ftp://ftp.lightwavecom.com).

3.3.4 3200 Network Cards

The earlier 3200 Network card (10baseT) is not supported by the 3230 Network / Control Card.
It will not function if installed.

Rev. A - 20 - www.lightwavecom.com

A Lantronix Company SCS3230 System Administrator's Guide

3.3.5 3200 10/100 Network Cards

The earlier 3200 10/100 Network card is not supported by the 3230 Network / Control Card.
It will not fun ction if installed.

3.3.6 Modem Card

The Modem Card is used primarily in the Console Server 3200 systems, however, it does not
provide or support any of the "secure" features of the SCS3230 system. It is not secure in the
sense that the modem circuitry is not subject to the encryption used for secure SSH
transactions, a primary reason for updating to the SCS3230. For this reason, the use of the
modem may be limited, or the modem may simply be disabled or removed, depending on your
site's application.

The modem card allows non-secure dial-in access to the SCS3230 and the servers attached to
its device ports. The modem card supports baud rates up to 38.4 kbps, and will auto-detect the
actual connection speed. Only one user at a time may access through the modem card, and
only one modem card may be installed per unit. The system administration functions may not
be accessed from the modem card.

4: Installation Instructions

Two options for your installation exist:

• you are either UPGRADING a CS3200 system to be an SCS3230 system, or

• you are installing a NEW SCS3230 system.

For simplicity, we will refer to a ConsoleServer 3200 system with the NETWORK/CONTROL
card installed as a SCS3220 system. In either case above, you will use THIS GUIDE for
administering the SCS3230 features and options, while referring to the ConsoleServer 3200
manual for a majority of the hardware installation instructions.

• When you purchase a CS3200 chassis, you will get the CS3200 manual (PN 15.00.017).

• When you purchase a SCS3230 NETWORK/CONTROL card, you will get the SCS3230

System Administrator's Guide (this manual, PN 15.00.038).

NOTE: The majority of this System Administrator's Guide is intended for the administration and
setup of the system, when using the SCS3230 kit. The hardware of the ConsoleServer 3200
may have been previously installed and is being upgraded at this time, or the system may be
installed as brand new installation.

Many hardware installation details are discussed in the ConsoleServer 3200 System Manual .
Not all are repeated in this manual.

4.1 Items in a SCS3230 Kit

The SCS3230 'kit' includes all of the cards and cables required to upgrade a CS3200 to the
SCS3230.

PN 500.000.0010 - 10/100 BT SECURE 3230 CARD KIT

includes:

- (1) 500.000.0014 -- 10/100 BT CNTL/NTWK Card

- (4) 500.000.0012 -- 3200 CHANNEL EXTENDER Card

- (4) 200.0161 -- CAT5 Cable, 24 inch long

This SCS3230 guide, PN 15.00.038 is included with each PN 500.000.0014 card.

Additional adapters and cables may also be included in the shipping container if ordered.
Orders with a large number of cables and adapters are usually shipped in separate containers.

If you are updating a CS3200 system, you may want to save your existing database from the
CS3200 and copy it into the SCS3230. To do so, you will use Backup to save the database,
and then Restore to copy it into the SCS3230's memory.

Rev. A - 22 - www.lightwavecom.com

A Lantronix Company SCS3230 System Administrator's Guide

4.2 Move Database from your CS3200 to SCS3230

The SCS3230 is designed to work with the Backup and Restore options found in the CS3200
product. Y ou can transfer your database from the CS3200 to the SCS3230. To accomplish this,
you must save the Backup the system database to a local PC, and then after upgrading the
hardware, you can then upload the saved information.

If you do not use Backup and Restore, you will have to re-program the system with port and
user information.

This section assumes some existing familiarity with the administration methods (logging in,
using the TERM port, etc.) of the CS3200 system, much of which will be similar with the
SCS3230 system.

4.2.1 Backup Procedure of your CS3200 System

Before shutting down the CS3200 System, you should backup the existing user database. This
is a normal CS3200 operation, as described in the 3200 documentation.

1. Log in as the sys admin on Control card port A on the CS3200's CONTROL card.

2. Make sure that there are no users logged in to the ConsoleServer 3200. If there are
any, have them log out or force them off the system using the FORCELOGOUT command.

3. In the communications program, begin the text file capture. Name the text file as
something that will indicate that it is the ConsoleServer 3200 parameters backup file, not
just a plain text file (i.e., 3200.bak and not 3200.txt).

4. Type the command BACKUP at the sys admin> prompt and press <ENTER>. Text will
be outputted to the screen; this text is equivalent to the binary data stored in the
ConsoleServer 3200's non-volatile memory. Wait several minutes while the
ConsoleServer searches memory for all non-zero records (unused records are skipped
in the backup).

5. After the sys admin> prompt returns, end the text file capture in the communications
program.

6. Open the text file with a text editor (such as Window's Notepad text editor, or StarOffice,
etc.).

7. Remove any text after but not including the line $BACKUP COMPLETE. DO NOT EDIT
ANY OF THE TEXT ABOVE THIS LINE! It is not necessary to remove the text after
$BACKUP COMPLETE, but it reduces the download time for the file during the RESTORE
process.

4.2.2 Restore Procedure

After the SCS3230 sy stem is operational, you can transfer your CS3200 database into the
system using the RESTORE option. After your database is saved in the SCS3230 system, you
can backup and restore the SCS3230's user database using Backup and Restore.

1. Log in as the sys admin on TERM port on the NETWORK / CONTROL card.

2. Make sure that there are no users logged in to the SCS3230. If any users are currently
logged on, have them log out or force them off the system by using the FORCELOGOUT
command.

15.00.038 - 23 - May 2002

ConsoleServer 3200 System Lightwave Communications

3. At the sys admin> prompt, type RESTORE and press <ENTER>. The SCS3230 will
prompt for confirmation to proceed with the parameter restore process. Type YES and
press <ENTER> to proceed. The system will ask for a second confirmation to proceed.
Type YES and <ENTER> to start the parameter restore process. After the second
confirmation, there is no text echoed to the screen indicating that the restore process is
proceeding.

4. Using the communications program, send the text file containing the backup records to
the SCS3230. Be sure to use text mode when transferring the file. The file download
should not take too much time; less than a minute is typical at 38.4K baud. After the
download is complete, the SCS3230 will re-zero all unused records. If a problem is
encountered during the text file transfer, the SCS3230 will abort the restore process and
return to the sys admin> prompt.

5. Once all unused records have been re-zeroed, the SCS3230 will reboot. Allow the
complete memory check to proceed; after it is done, log in as the sys admi n at the
LCI3200> prompt.

6. The ConsoleServer is restored to its previous settings and is ready for use. Check that
all user, terminal, device, and other parameters are correct and acceptable.

4.2.3 To RESTORE from a 3200 to a 3230

Use a terminal emulation software on a PC connected to the sysadmin port of a 3200. Ensure
that software flow control (XON/XOFF) is turned on for the software.

1. Implement a capture to file.

2. type “backup”.

3. Wait until you see “$BACKUP COMPLETE”

4. edit the backup file and remove any information before the line which starts 0,… This is
probably the first line. Also remove the couple of lines that say $BACKUP COMPLETE. After
the backup there will be some extraneous information, this needs to be removed.

Copy the file to the 3230. This can be accomplished using pscp or scp
Log in to the 3230 and establish yourself as root.

Cd to /lci/bin
Step 1) Type ‘restore “file name” yes’
“file name” is the name of the file you just copied.
The last yes is needed if you want to be told what passwords the system is inserting for this
user. If you do not want to see the passwords, do not type anything.

Unless there is an issue, you will observe users being added to the system and any changes
that take place to the user name or password. If you receive a message about record number
being incorrect, the file is either corrupt from flow control or you have not edited out the
extraneous information that is in the file from doing the backup.

If the service multidrop is running you will be asked to stop it and told how to do so ‘type
“service multidrop stop”’. Goto step 1.

4.2.4 LCI Update

There are four binary (.bin) files in the /lci/bin directory of the Network/Control card that may be
needed to update existing 3200 cards for use with the new Network/Control card's firmware:

- fterm.bin

- rterm.bin

- fdevice.bin

- rdevice.bin

These files are stored on the Network/Control Card in the /lci/bin directory on the card. The files
may also be downloaded from the Lightwave FTP site (ftp://ftp.lightwavecom.com). The

customer will use the lciupdate program to install these updates, however, they do not need to
transfer the binary files from an external computer to the 3200 - they should just direct
lciupdate to use the /lci/bin path.

It is not necessary to update the Device or Terminal cards before assembling the system,
however, before the system is put into service, the cards should be updated.

To Update a Card or Cards

From the 3230 bash shell, type the following.
[If you are in the sysadmin shell on a 3230, type ‘exit’ to get to the 3230 bash shell.]

• Establish yourself as super user

• Type ‘service multidrop stop’

• Type ‘ps –ax’ and look for any processes that contain the title multdrop.

• If any multidrop processes exist, type ‘killall multidrop’. Type ps-ax and again look for

any multidrop processes. If there are any, type ‘kill –9 “the number in the farthest left
column on the same line as the process”’, do this for all multidrop processes.

• Type lsmod and look for mdser. If mdser is not present type insmod mdser.

• If you wish to change the card binary file (*.bin) stored on the SCS3230, copy the update

file (filename.bin) to the 3230 and place in the “/lci/bin” directory.

• Type ‘/lci/bin/lci_update “[card letter][processor number]” file’. Where file is the name of
the file you for the slot you are updating. For instance you would probably type

• /lci/bin/lci_update b1 fterm.bin for terminal cards (the file name may be different and b
could be b,c,d,e)

• /lci/bin/lci_update h1 fdevice.bin for device cards (the file name may be different and h
could be h,I,j,k,l,m,n,o)

• The processor number is relevant to multiprocessor cards. You will be informed if it is
anything other than one.

4.3 Connecting to the TERM Port

The cable kit P/N 200.0135 contains the necessary adapters to interface the system TERM port
on the NETWORK / CONTROL card to a laptop or a terminal. Using the adapters in the kit,
follow the steps outlined below.

The communications settings for the system administrator port (TERM) are fixed at 9600 baud,
one stop bit, no parity, eight data bits, and DCE (9600 8N1 DCE).

NOTE: The administration functions may also be reached via telnet. However, it is first
necessary to configure the network ports through the direct serial connection.

1. Turn on power to the terminal or computer. If using a computer, start the desired
communication program. The terminal or communications program used must
be in VT100 emulation mode. Note that the VT100 functions keys are not always
mapped to the terminal or computer function keys; consult the appropriate
documentation for further information.

2. Ensure that the communications settings of your Terminal are correct.

3. Locate the serial port on the terminal or computer and determine what type of
connector is used. The cable kit included with the SCS3230 contains each of the
following: one RJ45 serial cable, an RJ45 to male DB9 adapter, an RJ45 to
female DB9 adapter, an RJ45 to male DB25 adapter, and an RJ45 to female
DB25 adapter. Select the appropriate adapter for the serial port on the terminal
or computer.

4. Firmly seat the adapter in the serial port. Screw down the adapter to secure it to
the serial port.

5. Insert one end of the serial cable into the adapter until a click is heard. I nsert the
other end of the serial cable into TERM port of the NETWORK / CONTROL card,
again until a click is heard.

6. Press <ENTER> on the keyboard. The login> (using Telnet) or login as: >
(using SSH) prompt should appear. If not, check that the SCS3230 is connected
to the appropriate power outlet, the power switch is on, the cards are firmly
seated, and that all cable connections are secure. If "garbage" characters
appear on the screen, check that the communications settings are correct.

7. The system administrator may now login to the system.

5: Connecting Equipment to the SCS3230

When connecting devices to the SCS3230, be sure to use Lightwave Communications
cables and adapters to ensure the proper transmission of data signals. If a device has
an RJ45 serial port, use the manufacturer's cable included with the equipment to
convert the RJ45 serial connector to a DB9 or DB25 connector, and then use a
Lightwave Communications adapter to convert back to RJ45 to attach to the device
port. Directly connecting the RJ45 port on the SCS3230 to the RJ45 port on a third­party device may not allow for the proper transmission of data signals.

5.2 NETWORK / CONTROL Card

The network port of the NETWORK / CONTROL card runs at 10/100 Mbits, half-duplex,
with auto-negotiation. The device used to connect the ConsoleServer to the network
(i.e., a hub or sw itch) must support this configuration.

Materials:

• SCS3230 network port

• network point-of-connection (i.e., a switch or hub)

• RJ45-terminated Cat 5 cable (standard LAN cable)

1. Configure the ConsoleServer network parameters to the desired values as
outlined in section 6.5.

2. Configure the network point-of-connection. It must be manually set to 10 Mbits, half­duplex, with no auto -negotiation.

3. Connect the ConsoleServer network port to the network using a standard LAN cable.

4. Check the status lights at the network end of the connection. It should indicate a good
link. Try reaching the IP address assigned to the ConsoleServer by using PING or
TELNET. If there is a problem, check the network configuration on both ends.

5.3 Modem Card

Materials:

• SCS3230 modem port

• Analog telephone line (POTS)

• RJ11 modular telephone cable

1. Locate the modular jack for the telephone line to be used. Select a telephone
cable with sufficient length to reach between the jack and the ConsoleServer.

2. Connect one end of the telephone cable to the jack. Connect the other end to
the ConsoleServer modem port.

3. Make sure the ConsoleServer is powered. Dial the telephone number of the line
connected to the ConsoleServer. The modem should automatically answer. If
not, check the telephone line and connections.

5.4 Device Card

NOTE: DEVICE Cards MUST be updated to Version 4.03 (or higher) firmware for SCS3230

The SCS3230 is designed so that the default device port communications settings will match
the communications settings of most Sun® server and workstation console ports (9600 baud, 8
data bits, no parity, one stop bit). Other equipment types (i.e., Cisco®) frequently use similar
communications settings; check the manuals included with the equipment for the correct
settings. The table below lists the default serial port communications settings for the SCS3230.
Sections 6.3 and 6.4 outline the commands for changing the terminal and device port
communications settings.

The following tables list the adapter part number and port configuration for some common
equipment types that may be connected to the SCS3230. Note that in some cases, an
additional cable or adapter is included with the equipment to convert a proprietary pinout to an
EIA-standard pinout. Also, note that it is not possible to connect the RJ45 serial port of the
ConsoleServer directly to the RJ45 serial port of any third-party equipment. Sun Netra
servers, Cisco switches, and other similar devices require a special adapter or cable to connect
to the ConsoleServer. The adapter or cable is usually provided by the manufacturer of the
equipment (e.g., Sun), or may need to be created by the user. The adapters and cables from
the equipment manufacturer are usually designed to interface directly to a terminal, so the
ConsoleServer device port must be configured as DTE rather than its default value of DCE.
Lightwave Communications has pre-made adapters and kits for some common equipment
types; contact Lightwave for information regarding your specific application.

Note: Some adapters are also available in quantity packs, and may be shipped under a different
part number. Quantity packs are "299.xxxx" compared to "200.xxxx".
