1: About this Guide
Purpose and Audience
This guide provides the information needed to install, configure, and use the Lantronix EMG™
edge management gateway. The EMG gateway is for IT professionals who must remotely and
securely configure and administer servers, routers, switches, telephone equipment, or other
devices equipped with a serial port for facilities that are typically remote branch offices or
“distributed” IT locations.
Note: EMG edge management gateways are referred to as either EMG or as EMG 8500
when referring to the specific series. Edge management gateway or console manager
may be used to describe the EMG devices.

2: Introduction
The EMG edge management gateway enables IT system administrators to manage remote
servers and IT infrastructure equipment securely over the Internet.
IT equipment can be configured, administered, and managed in a variety of ways, but most
devices have one of two methods in common: via USB port and/or via 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. The EMG gives the administrator a way to access them
remotely from anywhere there is a network or modem connection.
EMG 8500 Overview
The EMG 8500 is a modular edge management gateway that offers serial RJ45 and USB console
connectivity with user swappable I/O modules and connectivity modules. The EMG unit can
accommodate up to two user swappable I/O modules (4 port serial RJ45 and/or 4 port serial USB).
For connectivity, the EMG provides dual Ethernet or dual small form-factor pluggable (SFP)
network ports and up to two user replaceable modules for one LTE cellular modem, and in a future
release for one Wi-Fi modem or dialup modem.

Configuration Methods
After installation, the EMG requires configuration. For the unit to operate correctly on a network, it
must have a unique IP address on the network. This IP address references the specific unit.
For details on how to configure the unit with basic network settings, see Chapter 4: Quick Setup.
The EMG provides the following methods for logging into the unit to configure EMG settings
monitor performance:
Web Manager: View and configure all settings through a secure, encrypted web interface
using most web browsers (Firefox, Chrome, or Internet Explorer with the latest browser
updates). See Chapter 5: Web and Command Line Interfaces.
Command Line Interface (CLI): The command mode may be accessed through Telnet, SSH,
Web Telnet/SSH or connecting a terminal (or a PC running a terminal emulation program) to
the unit’s console port. See Chapter 5: Web and Command Line Interfaces.

Two I/O Modular Device Port Bays
- Two I/O Module Bays are available to accommodate a total of 8 device ports depending
on the number of I/O modules installed. Configuration possibilities are listed below. See
Table 3-9 on page 44 which describes different I/O module configurations.
Up to two 4 port RJ45 I/O modules can be installed to provide a maximum of 8 serial
RS-232C (EIA-232) device ports. The serial RJ45 ports match the RJ45 pinouts of the
console ports of many popular devices found in a network environment, and where
different can be converted using Lantronix adapters. The RJ45 ports have software
reversible pinouts to switch between digital terminal equipment (DTE) and digital
communications equipment (DCE) applications. See Appendix C: Adapters and
Pinouts on page 409 for more information on serial adapters and pin-outs.
Up to two 4 port USB I/O modules can be installed to provide a maximum of 8 USB
type A device ports.
A combination of 4 port USB I/O modules and 4 port RJ45 I/O modules can be
installed to provide up to 8 serial device ports.
- One serial console port (RJ45, RS-232) for VT100 terminal or PC with emulation with
light emitting diode (LED) for activity indicators

One LTE cellular modem module can be installed to provide cellular connectivity.
- Network Interface: Dual 10/100/1000 Base-T Ethernet port I/F card. Ethernet ports are
referred to as Eth1 and Eth2 in the user interface and this user guide.
- Network Interface: Dual 1 Gigabit-capable SFP port I/F card to support single or multi-
mode fiber optic SFP transceiver modules. SFP transceiver modules are referred to as
SFP1 and SFP2 in the user interface and this user guide.
Note: EMG will recognize two network connections. Either Eth1 or SFP1 is active, but
not both. Similarly, either Eth2 or SFP2 is active, but not both.
Lantronix offers SFP Transceivers (“modules”) for EMG 8500 edge management
gateways and SLC 8000 console managers with fiber SFP ports. To learn more, go to
https://www.lantronix.com/products/sfp/
SFP transceiver modules are provided by users according to fiber mode and brand
preferences.
EMG™ Edge Management Gateway User Guide 27
Network ports and the SFP port have LEDs to indicate link and activity status. If a
single mode and a multi-mode are both installed on the EMG unit, the device can be
configured to utilize one mode at a time.
- Power supply inlet: The unit accepts a 9 to 30 Vdc power input via a back-panel
connector. A universal AC power input (100-240V, 50/60 Hz) to 12 Vdc power supply brick
is available for use with the unit.
System Features
This section describes system features, interfaces, and ports of the EMG.
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 Radius, TACACS+, NIS, and LDAP. Groups are supported in LDAP, RADIUS (using VSA), and
TACACS+ (using priv_lvl).
2: Introduction
Device Port Buffer
The EMG unit 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.
Console Port Interface
The EMG unit supports local access through a dedicated front panel serial console port (see
Figure 2-3). The console port supports the RS-232C (EIA-232) standard. RJ45 cabling (e.g.,
category 5 or 6 patch cabling) is used.
Figure 2-5 and Table 2-6 show the Console port and port pinout.
The console port supports the following baud rate options: 300, 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, 460800, and 921600 baud.

Device Port Interfaces
RS-232 RJ45 Interface
The device ports are located on the front of the EMG unit in the I/O module device port bays (see
Figure 2-3).
All devices attached to the RJ45 device ports must support the RS-232C (EIA-232) standard. For
serial RJ45 device ports, RJ45 cabling (e.g., category 5 or 6 patch cabling) is used.
Serial RJ45 device ports for the EMG are reversed by default so that straight-through RJ45 patch
cables may be used to connect to Cisco and Sun RJ45 serial console ports. See Figure 2-7 and
Table 2-8. The RJ45 ports have software reversible pinouts to switch between DTE and DCE
applications.
Note: RJ45 to DB9/DB25 adapters are available from Lantronix. For serial pinout
information, see the Appendix C: Adapters and Pinouts on page 409.
Additional device port features:
RAW TCP, Telnet or SSH to a serial port by IP address per port or by IP address and TCP port
number
Simultaneous access on the same port - “listen” and “direct” connect mode
Device ports support the following baud rate options: 300, 600, 1200, 2400, 4800, 9600,
19200, 38400, 57600, 115200, 230400, 460800, and 921600 baud.
USB Interface
EMG™ Edge Management Gateway User Guide 29
2: Introduction
The USB device ports are located on the front of the EMG unit in the I/O module device port bays
(see Figure 2-3). USB device ports can be used with a USB type A connector to serial adapter, if
needed.
I/O Modules
EMG provides two I/O slots for user replaceable I/O modules to be installed on the front side of the
EMG 8500 unit.
Figure 2-7 shows a sample configuration of an EMG 8500 unit containing one 4 port USB I/O
module in Bay 1 and one 4 port RJ45 I/O module in Bay 2 for a total of 8 device ports.
Note: When installing the I/O modules, they can be populated or swapped in any order.
One but not both of the slots can be empty. The I/O modules must only be installed on the
front of the unit, never in the connectivity slots on the back.
