EMG™ Edge Management Gateway User Guide 23
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 a 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.
This chapter provides an introduction to the following EMG models:

EMG 8500

EMG 7500
Most features are common to both EMG 8500 and EMG 7500, however, differences between the
two models are noted.
