Product Overview

Enterasys’ leadership position in the switching market is further enhanced by the Enterasys

SecureStack™ A2 stackable enterprise switch. The SecureStack A2 is a high-performance 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. With support for

8,000 MAC addresses, the A2 is an excellent choice for environments that require complete

multilayer switching capabilities and support for high density (10/100Base-T, 100Base-FX)

Ethernet ports. The A2 is well suited for 100Mb networks that may also require Gigabit Ethernet

uplink connections. In addition to its complete multilayer switching capabilities, the A2 also

provides multilayer packet classiﬁcation and priority queuing for differentiated services. Along

with a switch capacity of 17.6Gbps, the A2 provides up to 48 10/100Base-T or 24 100Base-FX

Ethernet ports as well as 2 10/100/1000 Ethernet ports, which can be used as uplink or stacking

connections. As many as 8 A2s can be interconnected in a single stack to create a virtual switch

that provides 140.8Gbps of capacity and up to 384 10/100Base-T or 192 100Base-FX Ethernet

ports as well as 32 10/100/1000 Ethernet ports for uplink or stacking connections.

Robust quality of service (QoS) features enable strong support for integrated multimedia networks,

including Voice over IP, video, as well as all types of data-intensive applications. The A2 provides 8

hardware-based priority queues for each Ethernet port to support a suite of differentiated services

with as many as 8 distinct priority levels. In conjunction with its non-blocking L2 switching

architecture, the A2’s intelligent queuing mechanisms ensure that mission-critical applications

receive prioritized access to network resources.

The A2 provides a secure network by utilizing its authentication and security features, which can be

applied at the port level or at the user level. The A2 supports a single user/device per port, which

can be authenticated via IEEE 802.1X or MAC address.

The SecureStack product line provides high port density in a 1u footprint and is environmentally

friendly by design. By maximizing port density within a given amount of rack space, the A2

minimizes its cooling requirements. The A2’s overall electrical requirement is further reduced by a

low current draw and an extreme tolerance for high environmental temperatures. A highly scalable

architecture and a Limited Lifetime Warranty ensures that an A2 network investment will sustain a

secure, feature rich and cost-effective network well into the future.
