NETGEAR ProSafe 48xGigabit + 4 SFP+ Smart Switch#

NETGEAR ProSafe 48-port Gigabit Stackable Smart Switch is the industry’s first smart switch with 10-gigabit connectivity – delivering maximum throughput in SMB networks for demanding tasks such as data replication and backup, virtualization, video on demand and high-volume transaction processing. At less than half the cost of a managed switch, the ProSafe 52-Port Gigabit Smart Switch provides 48 gigabit ports for connecting devices to the network, along with four 10GE SFP+ ports for stacking or uplink to servers. As many as six switches can be stacked for a total of 288 network ports, with full redundancy for unsurpassed reliability. The GS752TXS offers a rich enterprise-class feature set, including advanced traffic management and security, yet can be easily configured and monitored through a web-based graphical user interface.

Important features:#

  • 48 x auto-negotiating 10/100/1000 ports
  • 4 x 10 GEbps SFP+ slots (port 49~52) to support 10GEbps optical module and 1G optical module
  • scalable SOLUTION
  • VLAN support
  • QoS support
  • ACL ((MAC, IPv4, IPv6 and TCP/UDP based)
