24-port Smart Switch with SFP uplinks

The Netgear GS728TX-300NAS is a rackmount 24-port Gigabit Ethernet switch with four dedicated SFP ports for fibre uplinks. It runs a Smart management layer that can be controlled through the Insight mobile app, cloud portal, web GUI or a lite CLI. Layer 3 static routing supports 32 IPv4 and 32 IPv6 routes for local inter-VLAN traffic. The unit draws a maximum of 26 W without PoE and operates at 26.80 dBA to 37.3 dBA at 25 °C ambient.

Suits small business networks needing

This switch fits organisations that want centralised configuration, monitoring and zero-touch provisioning across multiple sites without a full command-line environment. It supports IEEE 802.1Q VLANs, DHCP server and relay functions, plus ACLs for traffic control. Buyers who require Power over Ethernet for phones or cameras should look elsewhere, as this model provides no PoE ports. Environments needing 10 GbE copper ports or higher uplink density than four SFP slots will also need a different platform.

Four SFP ports decide uplink flexibility

The four SFP ports are the only interfaces that can carry uplinks above 1 Gbps, so the choice of SFP transceivers determines whether the switch connects to 1 GbE or 10 GbE fibre backbones. All 24 RJ45 ports are limited to 10/100/1000 Mbps negotiation. If the network design demands more than four high-speed uplinks or copper 10 GbE connections, this chassis cannot meet that requirement.

Questions about this item

What speed do the 24 RJ45 ports and 4 SFP ports actually deliver?

The 24 RJ45 ports run at 10/100/1000 Mbps; the 4 SFP ports are 10G SFP+ for high-speed fiber uplinks.

What physical space and mounting hardware does this switch need?

It measures 440 x 257 x 43 mm (17.3 x 10.1 x 1.7 in) and weighs 3.08 kg; rackmount brackets are included for a standard rack.

How do I get the switch configured the first time, and where do people get stuck?

Connect it to the network, adopt it through the Insight mobile app or Cloud Portal for zero-touch provisioning; the common slip is forgetting to set the management VLAN before applying policies.
