TP-Link TL-SG1210P 10-Port Gigabit PoE+ Switch: features, specs and who it suits

The TP-Link TL-SG1210P is a compact desktop network switch with ten ports, eight of which can supply power over Ethernet. It lets one cable carry both data and power to devices such as IP cameras, wireless access points and VoIP phones, so they don't each need a nearby outlet. Here is what the specs mean and what to match them against.

Ports and layout

TP-Link lists nine 10/100/1000Mbps RJ45 ports plus one gigabit SFP port. Eight of the RJ45 ports support PoE+. The remaining RJ45 port is a normal data port, which is where an uplink to a router or a non-powered device would usually go. The SFP slot takes a small fibre or copper module, handy for a longer uplink to another switch or building.

All the copper ports run at gigabit speeds and auto-negotiate down to 100 or 10Mbps for older gear.

What PoE+ means

Power over Ethernet sends electricity along the same twisted-pair cable as the data. The TL-SG1210P is compatible with IEEE 802.3af and 802.3at devices. Standard 802.3af (PoE) delivers up to 15.4W per port at the switch, and 802.3at (PoE+) up to 30W. TP-Link says each PoE port here can supply up to 30W.

Devices that are powered this way are called powered devices, or PDs. Many cameras and access points use well under 30W, while pan-tilt-zoom cameras with heaters can use more, so it is worth checking each device's power label.

The 63W total

The number that matters most is the total. TP-Link states that all the PoE ports together can provide 63W. That is less than eight ports at 30W (240W), so the switch can't run every port at maximum at once. In practice, if you connect devices drawing 5 to 12W each, you can power several of them. Add up the draw of every device you plan to connect and keep that sum under 63W, ideally with some headroom.

Traffic handling

The listing mentions 802.1p/DSCP QoS. Quality of Service tags let the switch give priority to time-sensitive traffic such as voice or video, so those streams are less likely to stutter when the network is busy. TP-Link says this keeps transfers smooth and free of delay.

Size and warranty

The listing gives the unit's weight as 1.4 lb. It is designed as a desktop switch, so it suits a shelf, desk or cabinet rather than a full-size rack, though you should check the product documentation for mounting options. TP-Link states a five-year warranty.

Who it suits

It suits a small office, a home lab or a home with a few PoE devices: two or three cameras, an access point or two, and a phone. It is less suited to larger installations where dozens of powered devices need much more total PoE power.

What to check before you buy

• Total power: add up the wattage of the devices you want to power and compare with 63W.
• Device standard: confirm your cameras or access points use 802.3af or 802.3at, rather than a proprietary or passive PoE scheme.
• Port count: eight powered ports may be fewer than you need once you count the uplink.
• Management: the listing doesn't describe VLANs or a web interface, so check the product documentation if you need them.
• Cable runs: PoE over Ethernet is generally limited to about 100 metres per cable.
• Uplink: decide whether you will use the SFP slot and, if so, which module you need.

The short version

• Ten-port desktop gigabit switch: nine RJ45 ports and one SFP slot.
• Eight ports support PoE+ (IEEE 802.3af/at), up to 30W each.
• Total PoE power of 63W across all ports.
• 802.1p/DSCP QoS and a five-year warranty.
