SecureLinx SLC Console Managers are members of the Lantronix SecureLinx IT
Management family of products. These products offer systems administrators and other
IT professionals a variety of tools to securely access and manage their resources.
Lantronix has been an innovator in this market with terminal servers and secure console
servers, as well as other remote access devices. The SLC Console Managers build on
that foundation and offer new features and capabilities.
IT equipment can be configured, administered, and managed in a variety of ways, but
most devices have one method in common: an RS-232 serial port, sometimes called a
console, auxiliary, or management port. These ports are often accessed directly by
connecting a terminal or laptop to them, meaning that the administrator must be in the
same physical location as the equipment. SLC Console Managers give the administrator
a way to access them remotely from anywhere there is a network or modem connection.
Many types of equipment can be accessed and administered using Console Managers,
including:
Servers: Unix, Linux, Windows 2003, and others.
Networking equipment: routers, switches, storage networking.
Telecom: PBX, voice switches.
Other systems with serial interfaces: heating/cooling systems,
security/building access systems, UPS, medial devices.
The key benefits of using Console Managers:
Saves money: Enables remote management and troubleshooting without
sending a technician onsite. Reduces travel costs and downtime costs.
Saves time: Provides instant access and reduces response time, improving
efficiency.
Simplifies access: Enables you to access equipment securely and remotely
after hours and on weekends and holidays—without having to schedule visits or
arrange for off-hour access.
Protects assets: Security features provide encryption, authentication,
authorization, and firewall features to protect your IT infrastructure while
providing flexible remote access.
SLC console servers provide features such as convenient text menu systems, break-safe
operation, port buffering (logging), remote authentication, and Secure Shell (SSH)
access. Dial-up modem support ensures access when the network is not available.

2: Overview
SecureLinx SLC User Guide 13
SLC Models
These SLC models offer a compact solution for remote and local management of up to
48 devices (e.g., servers, routers, and switches) with RS-232C (now EIA-232) compatible
serial consoles in a 1U-tall rack space.
All models have two Ethernet ports, referred to in this User Guide as Eth1 and Eth2.
Note: One possible use for the two Ethernet ports is to have one port on a
private, secure network and the other on a public, unsecured network.
This User Guide covers the following products:

The products differ only in the number of device ports provided and in AC or DC power
availability. Some models have dual entry redundant power supplies for mission critical
applications. They are available in AC or DC powered versions. The following figure
depicts the SLC48; the other models are similar.

Protocols Supported
The SLC supports the TCP/IP network protocol as well as:
SSH, Telnet, PPP, NFS, and CIFS for connections in and out of the SLC
SMTP for mail transfer.
DNS for text-to-IP address name resolution
SNMP for remote monitoring and management
FTP and SFTP for file transfers and firmware upgrades
TFTP for firmware upgrades
DHCP and BOOTP for IP address assignment
HTTPS (SSL) for secure browser-based configuration
NTP for time synchronization
LDAP, NIS, RADIUS, CHAP, PAP, Kerberos, and TACACS+ for user
authentication
For brief descriptions of these protocols, see D: Protocol Glossary.
Access Control
The system administrator controls access to attached servers or devices by assigning
access rights to up to 128 user profiles. Each user has an assigned ID, password, and
access rights. Other user profile access options may include externally configured
authentication methods such as NIS and LDAP.
Device Port Buffer
The SLC supports real-time data logging for each device port. The port can save the data
log to a file, send an email notification of an issue, or take no action.
You can define the path for logged data on a port-by-port basis, configure file size and
number of files per port for each logging event, and configure the device log to send an
email alert message automatically to the appropriate parties indicating a particular error.
Configuration Options
You may use the backlit front-panel LCD display for initial setup and later to view and
configure current network, console, and date/time settings.
Both a web interface viewed through a standard browser and a command line interface
(CLI) are available for configuring the SLC settings and monitoring performance.

2: Overview

unit. The SLC uses convection cooling to dissipate excess heat.

Physical Installation
To install the unit in a rack:
1. Place the unit in a 19-inch rack.
Warning: Be careful not to block the air vents on the sides of the unit. If
you mount the SLC in an enclosed rack, we recommended that the rack
have a ventilation fan to provide adequate airflow through the unit.
2. Connect the serial device(s) to the SLC device ports. See Connecting to a Device
Port on page 20.
3. Install any PC Cards you intend to use. If you install a modem card, connect to the
phone line. See 11: PC Card.
4. You have the following options:
a) To configure the SLC using the network, or to monitor serial devices on the
network, connect at least one SLC network port to a network. See Connecting
to a Network Port on page 21.
b) To configure the SLC using a dumb terminal or a computer with terminal
emulation, connect the terminal or PC to the SLC console port. See
Connecting a Terminal on page 21.
5. Connect the power cord, and apply power. See Power on page 22.
6. Wait approximately a minute and a half for the boot process to complete.
When the boot process ends, the SLC host name and the clock appear on the LCD
display.
Now you are ready to configure the network settings as described in 4: Quick Setup.
Connecting to a Device Port
You can connect any device that has a serial console port to a device port on the SLC for
remote administration. The console port must support the RS-232C interface.
Note: Many servers must either have the serial port enabled as a console or the
keyboard and mouse detached. Consult the server hardware and/or software
documentation for more information.
To connect to a device port:
1. Connect one end of the Cat 5 cable to the device port.
2. Connect the other end of the Cat 5 cable to a Lantronix serial console adapter.
Note: To connect a device port to a Lantronix SLP, use the rolled serial cable provided
with the unit, a 200.2225 adapter and Cat 5 cabling, or the ADP010104 adapter that
eliminates the need for an additional Cat5 patch cable between the adapter and the
connected equipment. See C: Adapters and Pinouts for more information about Lantronix
adapters.
3. Connect the adapter to the serial console of the serial device.
