Choosing equipment for homelab networking & firewalls often comes down to scale: do you need a straightforward way to add wired connections, or a managed switch designed for powered devices and more demanding network plans? The TP-Link TL-SG105 and Lantronix SISPM1040-582-LRT answer those needs very differently.
Quick verdict
Choose the TP-Link TL-SG105 for a small, uncomplicated wired setup where plug-and-play operation matters most. Choose the Lantronix SISPM1040-582-LRT when managed control, powered networking, or a hardened design is central to the project. The listed prices are separated by $569.59, making the intended use especially important.

Where each product wins
TP-Link TL-SG105
The TP-Link wins for the basic end of the decision. Its "unmanaged metal desktop network switch" format directly matches a small wired extension, and its plug-and-play description keeps the setup focused on connecting devices rather than configuring a management interface. It is the clearer fit for a home office or compact homelab bench where the main requirement is dependable Ethernet expansion.
Lantronix SISPM1040-582-LRT
The Lantronix wins when the project calls for managed equipment and a hardened form factor. Its web GUI and CLI management provide a concrete control path, while the product description identifies PoE++ support and SFP connectivity for a broader network design. The stated operating range of -40° to +75° C and fanless design further define the environments this switch is intended to address.
Product notes
TP-Link TL-SG105
The TL-SG105 is a practical choice when the job is adding a handful of wired connections. Its product title specifies five ports, an unmanaged design, and a metal desktop format, while the description calls out plug-and-play setup. That combination suits a small homelab bench, workstation cluster, or home office where you want to connect Ethernet devices without introducing a management layer. The concrete limitation is its five-port scale: that layout can become restrictive as the number of wired endpoints grows. It is also not the natural match for a project whose requirements begin with PoE++ power or GUI and CLI administration. Choose it for straightforward desktop expansion and a compact connection count.
Lantronix SISPM1040-582-LRT
The SISPM1040-582-LRT earns consideration when the network needs more than basic switching. It is described with eight PoE++ ports and two 100/1000 dual-speed SFP slots. Its power detail is specific: up to 90 watts per port on four ports, or 60 watts per port on eight ports simultaneously. The stated -40° to +75° C operating range and fanless design add a defined environmental profile. The limitation is fit: that broader hardware package is more than a simple few-device Ethernet extension requires. Pick the Lantronix when powered endpoints, SFP connectivity, or the stated temperature range are concrete requirements rather than optional extras.
Final choice by use case
- For a few wired devices and minimal configuration: choose the TP-Link TL-SG105.
- For powered network equipment: choose the Lantronix SISPM1040-582-LRT because its PoE++ specification is central to the design.
- For a managed homelab network: choose the Lantronix SISPM1040-582-LRT for its listed web GUI and CLI controls.
- For the lower listed-price commitment: choose the TP-Link TL-SG105 at USD 29.99; the Lantronix is listed at USD 599.58.
The decision is straightforward once the requirement is clear: the TP-Link is the compact unmanaged desktop switch, while the Lantronix is the managed PoE++ and hardened-network choice.
