Overview:

Powerful Connectivity and Security

As a leading provider of network equipment for SMBs, NETGEAR® understands the importance of reliable and high performance networks that are SMB budget aware. With the growth of virtualization, cloud-based services and applications like VoIP, video streaming and IP surveillance, SMB networks need to extend beyond simple reliability to performance and security. The NETGEAR S350 Gigabit Smart Switch series is tailored to these essential network needs of your business; delivering unprecedented non-blocking Gigabit bandwidth and solid network security at an affordable cost.

The NETGEAR Smart S350 series consists of five switch models, including 8-, 24- and 48-port Gigabit Ethernet switches and 8-, and 24-port Gigabit Ethernet PoE+ switches with 2 or 4 SFP ports for fiber uplinks, offering powerful Layer 2 features, enhanced performance and ease of use. They are purposely designed for converged networks where voice, video, data are all carried on a single network platform. Advanced features such as L2/ L3/L4 Access Control Lists (ACLs), Quality of Service (QoS), Link Aggregation Control Protocol (LACP) and Spanning Tree Protocol (STP) will ensure a high-speed and highly secured network environment for your business.

The 8-port S350 series switch models are in small “desktop” form factors, which will not take much space to place. The 24- and 48-port models are also rack-mountable. All models include Kensington lock slot to physically secure your switch in open space. The fan-less 8-port models and 24- port non-PoE model will operate silently, ideal for the noise-sensitive environment. The 24-port PoE+ model and 48-port model also work under 33dBA acoustic level. All NETGEAR S350 Series switches support IEEE 802.3az Energy Efficient Ethernet mode, caring power saving for your business. NETGEAR S350 Series is covered by a 5-year limited Hardware Warranty* and extendable support, offering a worry-free user’s experience at very affordable total cost of ownership.

Why is the NETGEAR S350 Series Gigabit Ethernet Smart Switch the right choice for SMBs?

As a leading provider of network equipment for SMBs, NETGEAR® understands the importance of reliable and high performance networks that are SMB budget aware. With the growth of virtualization, cloud-based services and applications like VoIP, video streaming and IP surveillance, SMB networks need to extend beyond simple reliability to performance and security. The NETGEAR S350 Gigabit Smart Switch series is tailored to these essential network needs of your business; delivering unprecedented non-blocking Gigabit bandwidth and solid network security at an affordable cost.

What you can expect from NETGEAR S350 Series Switches:

  • One-wire installation with 8, 12 or 24 Gigabit ports with PoE+ options (55W or 190W PoE total budget), and 2 or 4 SFP ports options provide not only redundant uplinks, but also build dual redundancy by a trunked uplink with link aggregation and failover redundancy.
  • Quiet and Cost-effective Smart Layer2 switches with essential business class network needs, ideal for voice, video and data convergence in office application
  • Smart switch features include VLAN, ACL, QoS, IGMP Snooping, LACP Link aggregation, STP and SNMP for enhanced security and reliability
  • Easy-to-use Web browser-based management GUI and full control through NETGEAR Smart Control Center, no need for an IT expert
  • 5-year hardware warranty with Next Business Day replacement, 90-day free technical support

Features and Benefits:

Hardware Features

  • Dedicated SFP Fiber Uplinks
    Dedicated SFP ports provides fiber uplinks without sacrificing any downlink Gigabit port. Up to 4 SFP ports provide not only redundant uplinks, but can also build dual redundancy by a trunked uplink with link aggregation and failover, the dualredundancy, a powerful design for the network virtualization
  • PoE+ Support on all ports (GS310TP and GS324TP)
    Flexible to plug-in or change into high-power PD devices on any port without worrying which one port to plug in and whether it will be running out of PoE+ ports.
  • Low Acoustics
    Fan-less design on GS308T/GS310TP/GS324T, and maximum acoustic noise level at 32.8dB for GS324TP and 26dB for GS348T respectively at 25°C (77°F) ambient for quieter office environment
  • Energy Efficient Ethernet (IEEE 802.3az)
    Maximum power reduction for ongoing operation cost savings.

Software Features

  • Advanced per port PoE controls
    Remote power management of PoE connected devices including operation scheduling (e.g. Wireless APs, IP security cameras, secure access door locks, IoT devices…)
  • ACL filtering to permit or deny traffic based on
    Provide granular network access control including L2/L3/L4 access control lists (ACLs).
  • Robust security features:
    Build a secured, converged network with all types of traffic by preventing external attacks and blocking malware, while allowing secure access for authorized users with RADIUS 802.1x port authentication.
    • 802.1x authentication (EAP)
    • Port-based security by locked MAC
    • DHCP Snooping
  • Comprehensive QoS features:
    Advanced controls for optimized network performance and better delivery of mission-critical traffic such as voice and video.
    • Port-based or 802.1p-based prioritization
    • Layer 3-based (DSCP) prioritization
    • Port-based ingress and egress rate limiting
  • Auto-VoIP, Auto-Voice VLAN, and Auto-Video VLAN
    Automatic Voice over IP prioritization (Auto-VoIP) simplifies most complex multi-vendor IP telephone deployments either based on protocols (SIP) or on OUI bytes (default database and user-based OUIs) in the phone source MAC address, providing the best class of service to VoIP streams (both data and signaling) over other ordinary traffic by classifying traffic, and enabling correct egress queue configuration. Similarly, Auto-Video VLAN enables IGMP snooping to minimize broadcast streams.
  • IGMP Snooping
    Facilitate fast receiver joins and leaves for multicast streams. Save cost and improve network efficiency by ensuring multicast traffic only reaches designated receivers without the need of an extra multicast router
  • Protected Ports
    Ensure no exchange of unicast, broadcast, or multicast traffic between the protected ports on the switch, thereby improving the security of your converged network. This allows your sensitive phone conversations to stay private and your surveillance video clips can be forwarded to their designated storage device without leakage or alteration.
  • DHCP Snooping
    Ensure IP address allocation integrity by only allowing DHCP messages from trusted DHCP servers and dropping malformed DHCP messages with a port or MAC address mismatch.
  • Dynamic VLAN Assignment (RADIUS)
    IP phones and PCs can authenticate on the same port but under different VLAN assignment policies. Users are free to move around and enjoy the same level of network access regardless of their physical location on the network.
  • Dual Firmware Images
    Dual firmware images for transparent firmware updates with minimum service interruption.
