Stackable L2/L3 Edge Switch
The Enterasys 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 Enterasys 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.
The A4 includes a 24 port model with a very quiet design that operates fan-less in a typical office
environment, making it ideal for classrooms and conference rooms.
A highly-scalable architecture, Enterasys policy, basic routing and a lifetime warranty ensure that an A4 network investment will sustain a secure, feature-rich, and cost-effective network well into the future.
