SCS1600/3200 User Guide 1: Introduction to the SCS Family

Protocol Support

The SCS supports the TCP/IP network protocol as well as:

 SSH, Telnet, and Rlogin for connections in and out of the SCS
 DNS and WINS for text-to-IP address name resolution
 SNMP for remote monitoring and management
 FTP for file transfers and firmware upgrades
 TFTP for firmware upgrades
 BOOTP, RARP, and DHCP for IP address assignment
 HTTP for easy browser-based configuration
 NTP for time synchronization and authentication
 NAT for enabling private networks to share a connection to the Internet.

SSH (Secure Shell): A secure transport protocol based on public-key cryptography.
Telnet: This terminal protocol provides an easy-to-use method of creating terminal

connections to any network host supporting Telnet.

Rlogin: Allows you to initiate a TCP/IP login session.
DNS (Domain Name Servers): Lets a network nameserver translate text node names

into numeric IP addresses.
SNMP (Simple Network Management Protocol): Commands that allow system

administrators to monitor and manage nodes on a LAN (Local Area Network) and
respond to queries from other network hosts. One community name can be configured
with read/write access. Refer to the SCS Reference Manual for SNMP configuration
instructions.

BOOTP, RARP, and DHCP: Methods for automatically assigning an IP address and
network settings.

NTP (Network Time Protocol): Used to synchronize time on networked computers and
equipment.

NAT (Network Address Translation): Allows private networks to share a single
connection to the Internet. With Port Mapping, specific IP Ports can be mapped from the
Internet to a private IP address and port.

This chapter provides a physical description of the unit and requirements for installing
and connecting it. The topics include:

 Connections
 Pinouts
 Cables and Adapters
 Specifications

Connections

The SCS1600 and SCS3200 are distinguished by the number of asynchronous RJ45
serial ports they are equipped with. The SCS1600 has 16 ports, while the SCS3200 has
32 ports. Both units include an AUI connector and a UTP port (10/100BASE-T) for
Ethernet connections. They both support baud rates between 300 and 230,400 bits per
second.

SCS3200 Front Panel

Note: The Reset button returns the SCS to its factory default configuration when

you press and hold it during the power-up and boot process. Resetting to factory
default will enable DHCP.

Pinouts

The SCS3200 has 32 asynchronous RJ45 serial ports. The SCS1600 has 16
asynchronous RJ45 serial ports. Pinout information for these ports is discussed in the
following sections.

RJ45 Serial Connectors

Lantronix servers are RS-423 compliant and are thus limited by the equipment at the
remote end of the serial line. If the SCS is connected to an RS-232 device, it is subject to
the RS-232 limits shown below. If connected to an RS-423 device, it is subject to the RS­423 limitations.

RS-232 lines are limited to 15m (50 ft) in length at 9600 baud, and 2 m (6 ft) at 115.2K
baud. RS-423 lines are limited to 300m (1000 ft) at 9600 baud, 85m (260 ft) at 115.2K
baud, and 40m (120 ft) at 230.4K baud. They will generally work at longer lengths.

The pinout of the serial ports is displayed below.

SCS1600/3200 User Guide 2: Connections and Physical Requirements

RJ45 Serial Connector

RJ45 to DB25

If you are connecting an RJ45 port to a DTE device (such as a terminal) that has a DB25
connector, you will need to use an RJ45-DTE DB25 adapter. To connect an RJ45 port to
a DB25 connector on a DCE device, you will need an RJ45-DCE DB25 adapter. The
pinout information for both connections is shown below.

RJ45 to DB9

The arrows in the figure below represent the direction of the signal. Both the transmit and
receive ground signals on the SCS connector are wired to the signal ground on a DB9
adapter.

33:: IInnssttaallllaattiioonn

This chapter covers all of the steps needed to get the SCS online and working.
EZWebCon is the preferred method for initial configuration, but this chapter also explains
alternative methods such as the command line interface. The full command set is
discussed in the SCS Reference Manual. Before you begin, consider the following
points:

 The IP address must be configured before any TCP/IP functionality is available.

You cannot use the web browser interface until an IP address is assigned.

 Most configuration commands require privileged user status. You must enter the

Set Privileged command to become the privileged user. The default privileged

password is system.

Connecting the SCS

Your SCS should be rack mounted in a secured environment. Refer to the following
illustration of a typical installation.

Installation Overview

3-1

SCS1600/3200 User Guide 3: Installation

1. Mount or place the SCS in a secure location.

2. Connect your active serial devices to the SCS's RJ45 serial connectors.

3. Connect the Ethernet network to the SCS via the 10/100BASE-T port
not both ports.

4. Connect the power cord to a power outlet.

5. Set the power switch to ON.

6. Confirm the following:
a) The green Power LED lights up immediately.
b) After about 20 seconds, the green Link LED lights up.
c) After about 30 seconds, the green OK LED blinks every two seconds.

Assigning an IP Address

You must assign an IP address to the SCS before you can perform any configurations.
We recommend you use the first method listed below, EZWebCon.

EZWebCon Method

EZWebCon is the recommended method for initially configuring the SCS. EZWebCon is
located on the distribution CD-ROM. Installation instructions are provided in the README
file.

Use the following steps to assign an IP address using EZWebCon:

1. Start EZWebCon.
