11:: IInnttrroodduuccttiioonn ttoo tthhee SSCCSS FFaammiillyy

The Lantronix SCS family of Secure Console Servers enables IT professionals to
remotely and securely configure and administer servers, routers, switches, telephone
equipment, or other devices equipped with a serial port. This user guide provides
information about three SCS products: the SCS100, SCS200, and SCS400.

These products provide the same functionality and software features but differ in
hardware and port configuration options. The SCS100 offers one serial RS232 port and
one 10/100 Ethernet port for physical connections. The SCS200 and SCS400 provide
added hardware functionality over the SCS100 with multiple serial ports and a PC card
interface. The PC card interface allows these products to leverage current and future PC
card technology such as 802.11 wireless, analog and cellular modems, and ATA storage
cards. The units support baud rates between 300 and 230,400 bits per second.

SCS100/200/400 User Guide 1: Introduction to the SCS Family

Note: See Using Menu/Connection Commands for information on how to send

intentional breaks to connected equipment.

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 configurations
 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: A terminal protocol that 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.

LEDs

LEDs indicate serial port activity. The SCS100 has five LEDs on the top of the unit. A red
LED during boot mode typically signals an error, but red LED patterns during normal
operations do not signal an error. Refer to the following table for an understanding of LED
functions:
