The TP-Link TL-SG2016P is a 16-port Gigabit smart managed switch, part of the company's JetStream range. Eight of its ports supply power over the network cable, which lets one cable carry both data and electricity to devices such as wireless access points and IP cameras. It suits small offices, workshops and well-wired homes that want more control than a basic unmanaged switch offers.
How the 16 ports are divided
Eight ports are PoE+ (802.3at/af) 10/100/1000 Mbps RJ45 ports. TP-Link rates each at up to 30W, with a total PoE allowance of 120W for the switch. The other eight are standard Gigabit ports with no power output, for computers, printers, network storage and other devices that have their own power supply.
The total matters more than the per-port figure. Eight devices drawing 30W each would need 240W, so they couldn't all run at full power at once. In practice, most access points and cameras draw far less than 30W, so 120W covers a good number of them, but it is worth adding up the power needs of what you plan to connect.
What PoE+ means
Power over Ethernet sends DC power down the same twisted-pair cable that carries data. The older 802.3af standard delivers up to about 15.4W per port at the switch, and 802.3at, known as PoE+, raises that to about 30W. The listing says the ports support both, so a range of powered devices should work, provided they follow those standards. It also removes the need for a power outlet at the spot where the device is mounted, which is handy for ceilings and outdoor walls.
Smart managed features
"Smart managed" sits between unmanaged and fully managed. You get a web interface and a set of configuration options without the complexity of a full enterprise switch. TP-Link lists these features:
- 802.1Q VLAN, for splitting one physical network into separate logical ones
- IP-MAC-Port binding, ACLs and Port Security, which limit what can connect and where
- DoS defend, storm control and DHCP snooping
- 802.1X RADIUS authentication
- L2/L3/L4 QoS, to prioritise certain traffic, and static routing
- IPv6 support and PoE recovery
Most home users won't need many of these. They tend to matter when you want a separate guest network, a camera network kept apart from the main one, or tighter control over which devices may connect.
Omada SDN and cloud access
The switch supports TP-Link's Omada SDN platform, which brings switches, access points and gateways into one management interface. It can be run with an Omada hardware controller or the software controller, and standalone mode also works. TP-Link also describes remote cloud access and the Omada app for managing the network across multiple sites.
One point from the listing deserves attention: SDN controllers work only with SDN switches, access points and gateways, while non-SDN controllers work only with non-SDN access points. The brand advises checking that your devices and controllers either have, or can be upgraded to, an SDN version.
Size and installation
The switch measures 11.3 x 4.4 x 1.0 inches (about 29 x 11 x 2.5 cm) and weighs 2.1 lb (about 1 kg). That is a slim, light unit, and it is the kind of size that usually suits a shelf or a rack with the right mounting kit. TP-Link lists a five-year manufacturer warranty.
Who it suits
It suits someone building a small network around several access points or cameras, a home office that wants VLANs, or an installer who prefers one managed system for several sites. A household that only needs a few more wired ports would likely not use most of its features.
What to check before you buy
- PoE needs: add up the wattage of the devices you plan to power and compare it with the 120W total.
- Standards: confirm your devices use 802.3af or 802.3at PoE rather than a proprietary scheme.
- Omada compatibility: check that your existing access points and controller support the SDN version.
- Mounting: check whether you need rack ears or a shelf, and the cable runs to the switch.
- Port count: 8 PoE and 8 non-PoE ports should suit your layout; plan for growth.
- Cabling: use good-quality Ethernet cable, and follow the manual for set-up.
The short version
- A 16-port Gigabit smart managed switch, with eight PoE+ ports and eight standard ports.
- Up to 30W per PoE+ port, with a 120W total PoE power.
- VLANs, ACLs, QoS, static routing, IPv6 and 802.1X authentication.
- Works with Omada SDN, via hardware or software controller, or standalone.
- Five-year manufacturer warranty, according to TP-Link.
