1.2 Product description
The NS3500-28T-4S is a 28-Port 10/100/1000Mbps with 4 Shared SFP Managed Gigabit Switch specially designed
to build a full Gigabit backbone to transmit reliable and forward data to remote network through fiber optic. It provides
28-Port 10/100/1000Base-T copper with 4 Shared 100/1000Base-X SFP fiber optic interfaces with inner power
system. Besides support for 20Gbps switch fabric to handle extremely large amounts of video, voice and important data
in a secure topology, the NS3500 provides user-friendly but advanced IPv6 / IPv4 management interfaces and
abundant L2 / L4 switching functions. It is the best investment for businesses/SOHOs expanding or upgrading their
network infrastructure. The features of enhanced management are shown below:
• 802.1X Authentication / RADIUS / TACACS+
• 802.1Q VLAN
• SNMP Monitor and SNMP Trap
• IGMP/MLD Snooping
• Rapid Spanning Tree
IPv6 / IPv4 Full-functioned Secure Switch
The NS3500 is the ideal solution to fulfilling the demand of IPv6 management Gigabit Ethernet Switch. It supports both
IPv4 and IPv6 management functions and can work with original network structure. It provides advanced Layer 2 to
Layer 4 data switching and Quality of Service traffic control, Access Control List, network access control and
authentication, and Secure Management features to protect building automation network connectivity with reliable
switching recovery capability that is suitable for implementing fault tolerant and mesh network architectures.
Spanning Tree Protocol for High Available Network System
The NS3500 features strong rapid self-recovery capability to prevent interruptions and external intrusions. It incorporates
Spanning Tree Protocol (802.1s MSTP) into customer’s automation network to enhance system reliability and uptime.
