| Gigabit Stackable Smart Switch comes with 48 10/100/1000 ports with
four shared SFP ports that provide high performance for
bandwidth-intensive applications like ERP and large file transfers.
In addition, two dedicated ports provide a 20 Gbps, dual-ring,
stacking bus that accommodates growth and offers the highest level
of resiliency, thus allowing you to stack up to six switches or 288
10/100/1000 ports and easily manage them all with a single IP
address. Finally, these switches come with a complete suite of
advanced features for more robust security, higher quality of
service and high availability. This switch is equipped with highly
advanced features such as Access Control Lists (ACL), 802.1x port
authentication, enhanced QoS, rate limiting and IGMP Snooping among
others to provide a small and medium-sized business with a network
that is geared for growth while providing scalability and
reliability.
