SLC™ Console Manager User Guide 17

2: Overview

SLC console managers are members of a secure 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.

5. 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 Chapter 4: Quick Setup .

Connecting to Device Ports

You can connect any device that has a serial console port to a device port on the SLC console
manager for remote administration. The console port must support the RS-232C interface.

Note: Many servers must 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™ power manager, 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 Cat 5 patch cable between
the adapter and the connected equipment. See Chapter 5: Adapters and Pinouts on page

272 for more information about Lantronix adapters.

3. Connect the adapter to the serial console of the serial device as shown in Figure 3-3.

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 to Terminals

The console port is for local access to the SLC console manager 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 emulation. The default baud rate is

9600.
To connect the console port to a terminal or computer with terminal emulat ion, Lantronix offers

optional adapters that provide a connectio n be twe e n an RJ45 jack an d a DB9 or DB 25
connector. The console port is configured as DTE. For more information, see Appendix E:

Adapters and Pinouts on page 272 and go to the Lantronix 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 th e terminal or start your computer ’s communication program (e.g., HyperTerminal for
Windows).

4. Once the SLC console manager is running, press Enter to establish connection. You should
see the model name and a login prompt on your terminal. You are connected.

4: Quick Setup

This chapter helps get the IP network port up and running quickly, so you can administer the SLC
console manager using your network. It contains the following sections:

 Recommendations
 IP Address
 Next Step

Recommendations

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 console manager, 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
available for download at http://www.lantronix.com/support/downloads/. If Eth1 cannot
acquire an IP address, you cannot use Telnet, SSH, or the web interface to run Quick
Setup.

IP Address

Your SLC console manager 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. Table 4-1 lists the options for assigning an IP address to your unit.

Method Description

DHCP A DHCP server automatically assigns the IP address and network

BOOTP Similar to DHCP but for smaller networks.

Table 4-1 Methods of Assigning an IP Address

settings. The SLC console manager is DHCP-enabled by default.
With the Eth1 network port connected to the network, and the SLC device

powered up, Eth1 acquires an IP address, viewable on the LCD.
At this point, you can Telnet into the SLC console manager, or use the

web interface.
