TP-Link TL-SG105-M2 5-Port 2.5G Desktop Switch
Upgrade Your Network to 2.5G — No Configuration Required
The TP-Link TL-SG105-M2 is a compact, plug-and-play 5-port 2.5G unmanaged switch designed to deliver multi-gigabit speeds to your home office, workstation, or small business network. With five 2.5Gbps ports, a fanless design, and zero configuration required, it's the simplest way to unlock the full potential of 2.5G-capable devices — including Wi-Fi 6 access points, NAS drives, and modern workstations.
Key Features
-
5× 2.5Gbps Ports — All five ports operate at up to 2.5Gbps, providing up to 2.5× the throughput of standard Gigabit switches.
-
Plug-and-Play — No software, no configuration, no management overhead — simply connect and go.
-
Fanless & Silent Operation — Completely silent fanless design makes it ideal for quiet office and home environments.
-
Compact Desktop Form Factor — Small footprint fits neatly on a desk, shelf, or inside a cabinet without taking up rack space.
-
Auto-Negotiation — Each port auto-negotiates to 100Mbps, 1Gbps, or 2.5Gbps, ensuring backward compatibility with existing devices.
-
IEEE 802.3az Energy Efficient Ethernet — Automatically reduces power consumption when ports are idle or lightly loaded.
-
Sturdy Metal Casing — Durable metal housing provides effective heat dissipation and long-term reliability.
Use Cases
- Connecting 2.5G-capable Wi-Fi 6/6E access points to a router or NAS
- Expanding multi-gigabit ports for home office workstations and NAS devices
- Aggregating wired connections from multiple PCs, smart TVs, or gaming consoles
- Providing a 2.5G uplink-ready switch for small business or retail environments
- Pairing with 2.5G-capable routers such as the TP-Link Omada ER707-M2

Frequently Asked Questions
Do I need to configure the TL-SG105-M2?
No. The TL-SG105-M2 is an unmanaged switch — simply plug in your devices and it works immediately. There is no software, web interface, or configuration required.
Will the TL-SG105-M2 work with my existing Gigabit devices?
Yes. All five ports auto-negotiate to 100Mbps, 1Gbps, or 2.5Gbps, so your existing Gigabit and Fast Ethernet devices will connect and operate normally alongside 2.5G devices.
What cable type do I need for 2.5G speeds?
Cat5e cabling supports 2.5Gbps at distances up to 100 metres. For best results and future-proofing, Cat6 or Cat6A is recommended.
Is the TL-SG105-M2 suitable for PoE devices?
No. The TL-SG105-M2 does not support Power over Ethernet (PoE). If you need to power IP cameras, access points, or VoIP phones, consider a PoE-capable switch such as the TP-Link Omada TL-SG2210P.
Can I use the TL-SG105-M2 with a Wi-Fi 6 access point?
Yes. Many Wi-Fi 6 and Wi-Fi 6E access points include a 2.5G uplink port. Connecting them to the TL-SG105-M2 ensures the wireless backhaul is not bottlenecked by a standard Gigabit connection.
Is the TL-SG105-M2 noisy?
Not at all. The TL-SG105-M2 uses a completely fanless design, making it completely silent — suitable for bedrooms, home offices, and quiet work environments.
