Chapter 1: Overview

Introduction
The x600 Series Switches are managed Gigabit Ethernet switches that act
as standalone units. There are five Basic Layer 3 switches in the series:
x600-24Ts Switch
x600-24Ts/XP Switch
x600-48Ts Switch
x600-48Ts/XP Switch
x600-24Ts-POE Switch
The AlliedWare Plus Operating System Software (AW+) runs on all the
x600 switches. The x600-24Ts-POE requires AW+ software version 5.3.3
or later for IEEE 802.3af support
For more detailed information about the switches, including illustrations,
see “Switch Descriptions” on page 21.
