EMG™ Edge Management Gateway User Guide

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.
