Product Overview
The Extreme Networks A4 is a highly reliable fast Ethernet edge switch that 
provides scalable, wire-rate performance in support of the bandwidth-intensive 
and delay-sensitive requirements of today’s demanding applications. The A4 also 
provides multi-layer packet classification and priority queuing for differentiated 
services. Along with a switch capacity of 17.6 Gbps, the A4 provides up to 48 
10/100 Ethernet ports as well as 4 Gigabit Ethernet uplink ports. Leveraging the 
A4’s stacking capability, as many as 8 A4s can be interconnected in a single stack 
to create a virtual switch that provides 140.8 Gbps of capacity and up to 384 
10/100 Ethernet ports as well as 16 Gigabit Ethernet uplink ports.
The A4 includes enterprise-class features in a 10/100 stackable switch that ensure 
seamless connectivity and application performance. With support for 16,000 
MAC addresses, the A4 is an excellent choice for medium to large enterprises that 
need to support thousands of endpoints. Support for Extreme Networks policy 
enables strong support for integrated multimedia networks, including Voice over 
IP (VoIP) and IP video, as well as all types of data-intensive applications. With the 
6.61 firmware release, all A4s can now deploy separate policies for both a personal 
computer and a VoIP phone on a single switch port. In conjunction with its non-
blocking L2 switching architecture, the A4’s intelligent queuing mechanisms ensure 
that mission-critical applications receive prioritized access to network resources.
