TL-SG1005LP review

The TL-SG1005LP is a five-port unmanaged switch from TP-Link. All five ports are 10/100/1000 RJ45. Ports 1 to 4 supply PoE+, and port 5 is a standard data port. It is plug-and-play, so there is nothing to configure.

That shapes who it suits. It is a simple way to add a few wired connections and power a handful of PoE devices from one small box. It is not a switch for anyone who wants to segment a network.

Every port runs at up to 1Gbps. The specifications list no 2.5GbE or 10GbE port, and no SFP uplink: all five ports are RJ45. If you need anything faster than Gigabit, this model does not offer it.

The port layout is straightforward. Ports 1 to 4 carry PoE and port 5 does not, so a router or upstream connection on port 5 leaves four ports for powered devices.

TP-Link lists a switch capacity of 10 Gbps, a 2K MAC address table and a 1 Mbit packet buffer. Jumbo frame support is listed as 9 KB on the V4 hardware and 16 KB on V3. Check which version you are buying if jumbo frames matter to you.

The PoE side is the main reason to look at this switch. Ports 1 to 4 support 802.3af and 802.3at, with up to 30 W per port. The total PoE budget is 40 W.

That total is the limit that matters. Four ports at 30 W each would come to 120 W, so the 40 W budget is shared across all four. TP-Link says intelligent power management cuts lower-priority ports when the budget is exceeded. Add up the rated draw of the devices you plan to connect before you buy, and keep it under 40 W.

The V4 datasheet lists a maximum power consumption of 46.9 W.

This is an unmanaged switch. The specifications list no web UI, no VLAN support and no SNMP. With none of those, you cannot split traffic into VLANs or monitor the switch over SNMP. What you get instead is a switch that works when you plug it in.

For a flat home or small office network, that may be all you need. For a homelab that uses VLANs to separate servers, IoT devices and guests, it falls short. You would need a managed model for that.

TP-Link's UK page lists a fanless design. With no fan, there is no fan noise to consider in a quiet room or on a desk. The datasheet gives a maximum heat dissipation of 159.46 BTU/h. Because that figure comes from the same hardware that carries up to 40 W of PoE load, leave some airflow around the case rather than packing it into a tight space.

Because the switch is unmanaged, there is no management firmware to configure. TP-Link has a UK support downloads page for the model, and datasheets exist for both V3 and V4. No firmware update history is listed.

One retailer lists the warranty as limited lifetime. TP-Link's own warranty page does not confirm that, so check the terms with the seller before relying on it.

The switch suits a small setup with a few PoE devices and a router on the spare port. Its fanless build and no-configuration setup fit a quiet desk or cupboard. If your devices together draw more than 40 W, or you need VLANs, faster ports or fibre uplinks, the listed specifications show it cannot do that.
