ProSafe 48-port Gigabit Smart Stackable Switch with 4 10G SFP+ slots

Powerful 10G Connections for Stacking and Uplink to Servers and Network Storage Systems

An ideal companion to the rapidly emerging class of 10-Gigabit servers; the NETGEAR Gigabit Stackable Smart Managed Switches (TXS) are the industry's first smart managed switches 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; this series of switches provides 24 and 48 gigabit ports for connecting devices to the network; along with four 10GE SFP+ ports for stacking or uplink to servers. The switches within this series are able to be mixed and matched in the same stack. As many as six switches can be stacked for a total of up to 300 network ports; with full redundancy for unsurpassed reliability. These switches offer 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.

Scalability and Reliability

The Stackable Smart Managed Switch with 10G uplinks series is a scalable solution that grows with a business. Starting with a single switch; the stack can grow to six switches with a mix of 24 and 48 port stack members and a total of up to 300 network ports. Two out of the four 10-Gigabit SFP+ ports on each switch can be used to create the stack; a single logical unit with up to 40 Gbps of stacking backplane that can be configured and managed as one switch - speeding up deployment while simplifying administration and maintenance. The stacked switches can be spread across multiple physical locations; by taking advantage of SFP+ fiber-optic connectivity; making the series of switches an ideal solution for remote and branch offices. All four 10GE ports can be used for network uplinks to servers and storage devices; or split with two ports for local or distant stacking and two ports for uplinks and link aggregation. Auto failover creates a safety net so that if one switch in the stack fails; all the other switches will be intact.

Enterprise-Class Features

With a rich set of L2+/Lite Layer 3 management features; this series of switches are efficient; secure and ready for the future. Static routing allows for segmentation of the network; with internal routing through the switch - reserving the router for external traffic routing only; making the entire network more efficient. Dynamic VLAN assignment increases security by imposing consistent policy and user credentials across the network; regardless of where users connect. Support for MLD Snooping greatly increase network efficiency by forwarding multicast traffic to designated hosts only; rather than flooding multicast packets across all ports. The GS728TXS also comes with full IPv6 support; comprehensive security and advanced multicast management.

Flexible Management Options

As a Smart Managed switch; IT administrators can decide how to manage the switches. Individual switches can be managed through a simple browser-based graphical user interface. The series of switches can also be managed through SNMP software for compatibility with existing SNMP-based consoles. For larger networks; the NETGEAR Smart Control Center can be used. It is a free Windows-based application for discovering; configuring and upgrading multiple smart managed switches across the network. Like all NETGEAR Smart Managed Switches; the Stackable Smart Managed Switch is backed by the NETGEAR ProSAFE Lifetime Warranty; and 1-Year ProSupport 24x7 Advanced Technical Support

Hardware Features

  • 10-Gigabit Connectivity: Fully exploits the power of 10GE servers Supports high-bandwidth applications such as data backup and replication; virtualization; video on demand and high-volume transaction processing
  • Stack Up to Six Switches: Scalable switching that grows with the enterprise Auto failover creates a safety net so that if one switch in the stack fails; all other switches will be intact
  • Four 10GE SFP+ Stacking/Uplink Ports: Up to 40 Gbps of stacking backplane Fiber-optic connections allow stacked switches to be placed in multiple physical locations; supporting remote or branch offices

Software Feature Highlights

  • Dynamic VLAN Assignment: Increases security by imposing consistent policy and user credentials across the network; regardless of where users connect
  • MLD Snooping: Increases network efficiency by forwarding multicast traffic to designated hosts only; rather than flooding multicast packets across all ports
  • Full Support for IPv6: Protects IT investment by future-proofing the network for the next generation of applications and extensions
  • DHCP Snooping: Prevent access layer attacks such as DHCP server attacks; ARP man-in-the-middle attacks and IP/MAC spoofing attacks by using IP-to-MAC binding information
  • Protected Ports: Increases security by isolating specific ports from communicating with other ports on the same switch Prevents an attacker from scanning a system to gain valuable services and information
  • Mixed Stacking Between GS728TXS and GS752TXS: Provide flexibility in network configuration. Expand your network as you need while ensuring higher usability of network resources.
