16-port 40/100 Gbps managed switch

The Netgear M4350-16C is a rack-mountable or table-top switch designed for high-density fibre networks. It delivers sixteen SFP28 ports operating at up to 100 Gbps alongside a single RJ45 management port. Full Layer 3 routing, VLAN support and 9216-byte jumbo frames suit enterprise and AV-over-IP deployments. TAA compliance and stackable architecture simplify large-scale rollouts.

AV integrators and data-centre engineers

Installations that rely on copper cabling or require Power over Ethernet will not be served by this optical-only platform. The unit draws 161.90 W, so sites without adequate cooling or power budgeting should evaluate alternatives. Small-office networks needing only 1 Gbps or 10 Gbps connectivity can use simpler, lower-cost switches instead.

16 SFP28 ports at 100 Gbps

The sixteen SFP28 interfaces are the decisive specification: they dictate the transceiver modules, fibre type and cable reach the infrastructure must support. Confirm that your optics and patch cords match 40GBase-X or 100GBase-X standards before purchase. The single RJ45 port is reserved for out-of-band management and does not carry production traffic.

Questions about this item

What SFP28 transceivers and single-mode or multimode fibre patch cables do I need to connect the 16 ports at 40 or 100 Gbps?

The 16 SFP28 ports accept 40GBase-X or 100GBase-X modules; you must supply matching transceivers and optical fibre patch cords for each link you intend to use.

Can I keep my existing 10 GbE SFP+ switches and uplink them to this unit without replacing them?

Yes, the SFP28 ports are backward compatible with SFP+ modules, so you can plug 10 GbE optics into any port and interoperate with older switches.

After racking the switch and loading a configuration, how do I verify all 16 SFP28 links are up at the expected line rate?

Log into the management interface, check each port status for link up and negotiated speed of 40 Gbps or 100 Gbps, and confirm traffic counters increment without errors.
