The TP-Link JetStream TL-SG3428X is a rack-width managed switch with 24 gigabit RJ45 ports and four 10G SFP+ slots. It adds Layer 2+ features such as static routing and integrates with TP-Link's Omada software-defined networking platform. It is aimed at small and medium business networks and ambitious home setups.
Ports and uplinks
The 24 RJ45 ports run at 10/100/1000 Mbps, which covers computers, printers, access points and cameras. The four SFP+ slots run at 10 Gbps and are typically used to connect to other switches, a server or a storage device, over fibre or direct-attach cable. TP-Link says they provide high-bandwidth connections with non-blocking switching capacity, which means the switch can handle all ports at full speed at once. SFP+ modules or cables are separate purchases.
What L2+ and managed mean
A managed switch lets you configure how traffic moves. TP-Link lists these capabilities:
- VLANs (802.1Q): split one physical switch into separate logical networks.
- QoS, IGMP and LAG: prioritise traffic, handle multicast, and combine links for more bandwidth or redundancy.
- Static routing (L2+): route traffic between internal networks directly on the switch, which saves load on the main router.
- IPv6 support.
Security features
The listing names IP-MAC-Port binding, ACL, port security, DoS defence, storm control, DHCP snooping and 802.1X RADIUS authentication. In general, these controls decide which devices may connect and limit the effect of misbehaving ones. Setting them up takes some networking knowledge.
Omada SDN and cloud management
The switch integrates with Omada SDN, which manages switches, access points and gateways together. TP-Link lists hardware, software and cloud-based controllers, and standalone mode also works. The listing marks some features, such as zero-touch provisioning, AI-driven technology and the cloud controller itself, as "coming soon", and notes that additional fees apply for the cloud-based controller. Check TP-Link's current documentation for what is available now.
Size and support
The switch measures 17.3 x 7.1 x 1.7 inches (about 44 x 18 x 4.3 cm), the width of a standard 19-inch rack, at 1U height, and weighs 4.3 lb (about 1.95 kg). TP-Link lists a five-year warranty and technical support from 6am to 6pm PST, Monday to Friday.
Who it suits
It suits small offices, schools, shops and home labs that want VLANs and central management, and especially people already using Omada access points or gateways. A simple home network with a few devices does not need it.
What to check before you buy
- Port speeds: all 24 copper ports are gigabit, so multi-gig devices will connect at 1G.
- PoE: the listing doesn't say it powers devices, so check if you need PoE for access points or cameras.
- SFP+ modules: confirm the right modules or cables for the other end of each link.
- Mounting: it is rack-width, so plan a rack, shelf or wall mount.
- Fan noise: check the manual for noise details if it will sit in a quiet room.
- Features: confirm which Omada and cloud features are available today.
