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 co sts.
Saves time: Provides instant access and reduces response time, improvin g
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.
SecureLinx SLC User Guide 12
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:

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.

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.
3: Installation
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 p rovided
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.

Figure 3-1. CAT 5 Cable Connection
Connecting to a Network Port
The SLC’s network ports (10Base-T/100Base-TX) allow remote access to the attached
devices and the system administrative functions. Use a standard RJ45-terminated
Category 5 cable to connect to the network port.
Note: One possible use for the two Ethernet ports is to have one port on a
private, secure network, and the other on an unsecured network.
Connecting a Terminal
The console port is for local access to the SLC and the attached devices. You may attach
a dumb terminal or a computer with terminal emulation to the console port. The SLC
console port uses RS-232C protocol and supports VT100 em ulation. The default baud
rate is 9600.
To connect the console port to a terminal or computer with terminal emulation, Lantronix
offers optional adapters that provide a connection between an RJ45 jack and a DB9 or
DB25 connector. The console port is configured as DTE. For more information,
see C: Adapters and Pinouts and our web site at www.lantronix.com/support. and click
Cable/Adapter Lookup on the Support menu.
.
To connect a terminal:
1. Attach the Lantronix adapter to your terminal (use PN 200.2066A adapter) or your
PC's serial port (use PN 200.2070A adapter).
2. Connect the Cat 5 cable to the adapter, and connect the other end to the SLC
console port.
3. Turn on the terminal or start your computer’s communication program (e.g.,
HyperTerminal for Windows).
4. Once the SLC is running, press Enter to establish connection. You should see the
model name and a login prompt on your terminal. You are connected.

Power
The SLC consumes less than 20W of electrical power.
AC Input
The SLC has a universal auto-switching AC power supply. The power supply accepts AC
input voltage between 100 and 240 VAC with a frequency of 50 or 60 Hz. Rear-mounted
IEC-type AC power connector(s) are provided for universal AC power input (North
American cord provided).
The SLC0xx12N models have a single supply/input, while the SLC0xx22N models have
dual inputs and dual supplies. The power connector also houses a repla ce able protective
fuse (fast-blow 4.0A, maximum 250V AC) and the on/off switch. In addition, we provide
the SLC0xx22N with a “Y” cord. (See SLC Models on page 13.)
Figure 3-2. AC Power Input and Power Switch (SLCxxxx2N)
Note: The SLC48 with dual AC does not have an on/off switch.
DC Input
The DC version of the SLC accepts standard –48 VDC power. The SLC0xx24T models
accept two DC power inputs for supply redundancy. Lantronix provides the DC power
connections using industry standard Wago connectors. One set of connectors is included
with the SLC. You can order additional connectors (part number 721-103/031-0 00) from

44:: QQuuiicckk SSeettuupp
This chapter helps get the IP network port up and running quickly, so you can administer
the SLC using your network. To set up the network connections quickly, we suggest you
do one of the following:
Use the front panel LCD display and pushbuttons.
Complete the Quick Setup web page on the web interface.
SSH to the command line interface and follow the Quick Setup script on the
command line interface.
Connect to the console port and follow the Quick Setup script on the command
line interface.
Note: The first time you power up the SLC, Eth1 tries to obtain its IP
address via DHCP. If you have connected Eth1 to the network, and Eth1 is
able to acquire an IP address, you can view this IP address on the LCD or
by running the Detector tool on the product CD. If Eth1 cannot acquire an IP
address, you cannot use Telnet, SSH, or the web interface to run Quick
Setup.
IP Address
Your SLC must have a unique IP address on your network. The system administrator
generally provides the IP address and corresponding subnet mask and gateway. The IP
address must be within a valid range, unique to your network, and in the same subnet as
your PC.
You have the following options for assigning an IP address to your unit.
Table 4-1. Methods of Assigning an IP Address
Method Description
DHCP
BOOTP
Detector™
A DHCP server automatically assigns the IP address and
network settings. The SLC is DHCP-enabled by default.
With the Eth1 network port connected to the network, and the
SLC powered up, Eth1 acquires an IP address, viewable on
the LCD.
At this point, you can Telnet into the SLC, or use the web
interface.
Similar to DHCP but for smaller networks.
A Windows-based application on the product CD for viewing a
DHCP-provided IP address or for assigning a static IP address
to the SLC. You can use Detector only if you have not already
assigned a static IP address by another method. For more
information, see Detector’s online help.
