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.
Reliability and Availability
The A2 design incorporates redundancy and failure protection mechanisms complete with automatic failover and recovery capabilities to provide a reliable network. An integral power supply is the primary source of power for the A2 and complete power redundancy is provided by an optional external power supply. In addition to the standard version of the A2, there is also a redundant Power over Ethernet (PoE) version of the A2 which supports network devices that require external power such as wireless access points, VoIP phones and network cameras. A virtual switch can be created by interconnecting as many as 8 A2s in a single stack, which can be managed via a single IP address with redundant management connections. The A2’s closed-loop stacking (CLS) capability utilizes bidirectional switch interconnects to maintain connectivity within the virtual switch despite any physical switch-level failure. Up to 4 Ethernet ports can be grouped together to create a multi-link aggregation group (LAG). A LAG’s Ethernet ports can be collocated on a single A2 or they can be distributed across multiple A2s within a stack to prevent a switch-level failure from disrupting data communications.
Advanced Quality of Service
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 in order to support a suite of differentiated services with as many as 8 distinct priority levels. The strict and weighted round robin queuing algorithms ensure that mission-critical applications receive prioritized access to network resources.
Security
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.
Investment Protection
The A2 is a cost-effective, feature-rich, stackable switch that provides a broad set of features today and will continue to deliver benefits well into the future. Customers can grow and/or enhance their networks while protecting their investment by adding A2s into existing A2 networks and/or stacks. When multiple A2s are stacked together, each switch in the stack assumes the feature set that is common to all switches in the stack to ensure operational compatibility. All SecureStack products include a Limited Lifetime Warranty that continues for 5 years after the date of product discontinuation.
