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. 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.These user swappable modules are also referred to as FRUs (field replaceable units) The EMG 8500 unit can accommodate up to two user swappable I/O modules (4 port serial RJ45 and/or 4 port serial USB).
