TP-Link TL-SL1226P 24-Port 10/100Mbps PoE+ Fast Ethernet Switch with 2 Gigabit Uplinks and 2 Combo SFP Slots
Product description
What it is and why you’d want it
The TP-Link TL-SL1226P is a 24-port Fast Ethernet PoE+ switch built for small-to-mid network setups where you want power and data delivered over Ethernet—one cable per device. “Fast Ethernet” is a clue: this is designed for everyday IP cameras, VoIP endpoints, and other 10/100Mbps gear, not for heavy 1GbE workloads on every port.
On paper, the pitch is straightforward. You get 24 PoE+ 10/100 RJ45 ports, plus uplinks and SFP flexibility for getting traffic back to your router/NVR or for extending connectivity. If you’re building a surveillance or voice-ready closet, it’s the kind of switch that reduces cabling mess and can keep deployment simple.
That said, Fast Ethernet does come with a limitation: you won’t get full throughput like you would with all-1GbE designs. If you’re planning a network that relies on higher-speed LAN traffic, you may feel constrained—still, for PoE camera and voice use, the spec choices make sense.
Key points (what matters day to day)
The most practical advantage here is PoE+ itself. With PoE+ on 24 ports, you can power supported devices directly without separate power bricks for each endpoint. TP-Link also specifies a total PoE budget of 250W and up to 30W per PoE+ port, which is a big deal when you’re mixing different camera types or other PoE+ consumers.
Two uplink approaches are also worth noting: you have 2 Gigabit RJ45 uplinks and 2 combo Gigabit SFP slots. That gives you more options for how you connect upstream or where you place the switch in a rack.
There are also operational features aimed at common real-world annoyances in networks used for video and voice. Priority mode is described for ports 1–8 to help maintain higher-quality video/voice transmission, and isolation mode is meant to isolate broadcast storm behavior for better LAN security and data transmission.
Key features that connect to real scenarios
Imagine a small surveillance run: you mount 8 IP cameras along a hallway, connect them to ports 1–8, then wire the switch to your NVR or recording device through the uplink. Priority mode is specifically intended to support high-quality video or voice data transmission for those lower-numbered ports—so your time on-site goes to installation, not troubleshooting.
For longer cable runs, the switch includes an “Extend Mode” where data and power transmission range can go up to 250m, with the important tradeoff noted by TP-Link: speed is downgraded to 10 Mbps under extend mode. That’s not a problem if the use case is distance-first, but it can be a dealbreaker if you expected full 100Mbps performance on those links.
If you’re worried about broadcast behavior—especially in networks with many endpoints—there’s isolation mode. It’s described as a way to isolate broadcast storm and improve LAN security and data transmission. It’s one of those features you may not notice until something starts acting up.

Pros and where it stands out
What you’ll like most, based on the design:
- PoE+ on all 24 RJ45 ports with a 250W budget means fewer power supplies and cleaner installs.
- Priority mode for ports 1–8 is targeted at video/voice traffic, which is exactly the kind of data you don’t want to be inconsistent.
- Extend Mode can help when your runs aren’t short—just be ready for the 10 Mbps speed reduction when you use it.
- The mix of Gigabit RJ45 uplinks plus combo SFP slots gives you flexibility if you want fiber uplink options or higher upstream performance.
Where you might hesitate:
- It’s Fast Ethernet (10/100Mbps). If your project needs consistently higher LAN speeds across many endpoints, this may feel like a ceiling.
- Extend Mode improves reach, but the speed downgrade is real, it can be slower than you expect if you don’t plan around it.
Who it’s for (and who should skip it)
It’s a solid pick if you’re deploying PoE-powered devices like IP surveillance cameras or voice endpoints and you want a single switch to handle both power and connectivity without extra setup.
It may not suit you if your priority is moving large amounts of data at higher speeds between devices on the LAN. Also, if you plan to rely heavily on Extend Mode for many links, keep in mind that you’ll be operating at 10 Mbps on those extended connections.
Buying verdict
Is it worth it?
Worth considering if you’re building a PoE-first network with 24 powered endpoints and you want targeted features like Priority mode (ports 1–8) and Isolation mode for broadcast storm control. The combination of 24 PoE+ ports, a 250W PoE budget, Gigabit uplinks, and combo SFP slots gives it practical flexibility for real deployments.
You may want to skip it if your network demands higher-than-Fast-Ethernet throughput for many endpoints, or if you can’t tolerate the Extend Mode speed downgrade when you need longer runs.
Mini FAQ
Can this switch power PoE+ devices directly?
Yes. The TL-SL1226P includes 24 PoE+ 10/100 RJ45 ports with support for up to 30W per port and a total PoE budget of 250W, as described in the product information.
What happens to speed in Extend Mode?
Under Extend Mode, TP-Link states that data and power transmission range can reach up to 250m, but speed is downgraded to 10 Mbps.
Which ports support Priority mode?
Priority mode is described for ports 1–8 to help maintain high-quality video or voice data transmission.
Does it include isolation features for network stability?
The switch is described as supporting Isolation Mode to isolate broadcast storm behavior and improve LAN security and data transmission.
How long is the warranty?
The product information states a 3-year warranty and free technical support from 6am to 6pm PST Monday to Friday.
