Product Overview
140.8 Gbps capacity and 104.8 Mpps
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.
Benefits
Business Alignment • Enterasys policy capabilities support
converged multimedia networks • Reliable network operation for mission-
critical applications
A 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.
There is nothing more important than our customers.
Advanced Quality of Service
Robust QoS features enable strong support for integrated multimedia networks, including VoIP and video, as well as all types of data-intensive applications. The A4 uses multiple standards-based discovery methods with Enterasys policy capabilities to automatically identify and provision VoIP services for IP phones from all major vendors. A4 switches provide dynamic mobility for VoIP clients to reduce operating costs; when an IP phone moves and plugs in elsewhere in the enterprise network, its VoIP service provisioning, security and traffic priority settings move with it, with no manual administration required.
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.
• Enterasys policy provided enhanced network security that is maintained concurrently with user mobility
• Architecture designed with integral network security
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.
• Highly available design ensures reliable network operations
Security
• Network access secured by 802.1x, MAC address and web-based authentication methods

Stackable L2/L3 Edge Switch
High-availability design assures reliable network operations
Now with Enterasys policy and basic routing
Operational Efficiency
• Scalable architecture supports continued growth of network capacity
• Consolidated management capabilities reduce network operational expenses
Reliability and Availability
The A4 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 A4 and complete power redundancy is provided by an optional external power supply. In addition to the standard version of the A4, there are also IEEE 802.3af Power over Ethernet versions 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 A4s in a single stack, which can be managed via a single IP address with redundant management connections. The A4’s closed-loop stacking capability utilizes bi-directional switch interconnects to maintain connectivity within the virtual switch despite any physical switch-level failure. Up to 8 Ethernet ports can be grouped together to create a multi-link aggregation group (LAG). The A4 can support multiple LAG’s distributed across several A4s within a stack to prevent a switch-level failure from disrupting data communications.
