High-Density 10G Switching That Stacks and Stays Up

The Netgear M4300-48X is a 48-port 10GBASE-T fully managed switch built for the mid-enterprise edge and SMB core, with four SFP+ slots for fiber or DAC uplinks. It runs the full L2/L3/L4 feature set with no licensing to unlock, and it stacks with other M4300 models so a network can grow without forklift upgrades. It is one of the higher-density options in our managed switches range, aimed at server rooms, collapsed cores, and Pro AV backbones.

Deployment Notes

  • Stacks 10G and 1G M4300 models together using any 10G port and media type (RJ45, SFP+, or DAC) for spine-and-leaf topologies.
  • High availability: Non-Stop Forwarding and hitless failover keep traffic moving if the stack master goes down.
  • Full Layer 3 routing (static, RIP, OSPF, VRRP, PIM, PBR) ships standard, with no add-on license required.
  • DHCP/BootP auto-installation automates firmware and config file uploads for hands-off rollouts.

Highlights

  • 48 x 10GBASE-T ports plus 4 x SFP+: line-rate 10 Gigabit copper with fiber and DAC uplink options.
  • License-free feature set: L2 switching and L3 routing are included out of the box.
  • OpenFlow 1.3 and SDN support keep the design future-ready even if SDN comes later.
  • Managed through CLI, web GUI, SNMP, sFlow, and RSPAN, with single-pane NMS300 for mass configuration.
  • Covered by the NETGEAR ProSafe Lifetime Hardware Warranty with lifetime next-business-day replacement.
