NS3500-28T-4S
PRODUCT DESCRIPTION

This Enterprise-Class Network Switch provides 28 Gigabit Ethernet


ports with 4 shared 100/1000Mbps SFP slots. This switch provides a


high-performance switch architecture and non-blocking switch fabric


capable of wire-speed throughput as high as 56Gbps.


 


User-Friendly Traffic Control


 Designed to deliver optimal IP video transmission performance for


applications with limited network resources, the NS3500-28T-4S


offers user-friendly traffic management features, including quick and


simple QoS configuration through a Web interface.


 


Flexible Management


The NS3500-28T-4S is equipped with console, Web and Simple Network


Management Protocol (SNMP) management capabilities, and can be


accessed via telnet. It also supports secure remote management via a


SNMPv3 connection which encrypts the packet content at each session.


 


Quiet, Energy-Efficient Technology


 Designed as a fanless switch, the NS3500-28T-4S provides a quiet,


energy-efficient, high-speed network environment, delivering Gigabit


performance at a cost similar to Fast Ethernet.
