Introduction

The G‐Series Ethernet switch is a modular, high‐density switch designed to handle networking demands in commercial and institutional settings, including education, government, and financial environments.

Overview

The G‐Series product family includes the G3G124‐24, G3G124‐24P, and G3G170‐24 base systems. These systems provide either 24‐10/100/1000 copper ports and two 1‐Gigabit Small Form Factor Pluggable fiber‐optic transceiver (SFP) combo ports, or 24 SFP ports, in the lower left front panel (fixed Slot 1). Power over Ethernet (PoE) is factory installed on the G3G124‐24P base chassis. The base systems also feature three front access I/O slots for installing optional additional IOMs.

Currently, there are four G‐Series product family IOMs available for the switch: a 24‐10/100/1000 copper port and 2 combo port SFP module (similar to the base system front panel interface configuration), a 24‐port SFP module, a 2‐port 10 Gigabit XFP module and a 4‐port 10 Gigabit XFP module.

The G‐Series switch can be placed as a freestanding unit or installed into a standard 48.26‐ centimeter (19‐inch) rack.
