schneiderEnterasys® SecureStack™ A2 Switch

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. For more information regarding warranty terms and conditions please go to

Performance & Scalability

The A2 provides scalable, wire-rate performance in support of the bandwidth-intensive and 

delay-sensitive requirements of today’s demanding applications. 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.
