Its highly available features include support for closed-loop stacking, redundant power, power over Ethernet (PoE), fault-tolerant management, rapid re-convergence, and link-aggregation. The closed loop stacking ensures that a single switch or cable connection failure in the stack will not impact the overall operation.

Up to eight SecureStack A2 switches can be supported in a single stack with one IP address for complete stack management. A single stack supports up to 384 10/100Mbps ports with 16 gigabit uplinks.
