The TP-Link SG108 is an inexpensive unmanaged gigabit switch that works well for simple Dante or control network setups where you just need to connect a few devices. Its tiny desktop form factor fits easily in a rack drawer or on a shelf, and it requires zero configuration. While it lacks the QoS and VLAN features of managed switches, it handles small Dante networks reliably when traffic is minimal.

The payoff
Network Switch decisions, organized around the whole rig.
The TL-SG108 is an unmanaged eight-port gigabit switch — the kind of piece that quietly holds a small network together without asking anything of you. In a live-audio rack its job is simple: give your DanteThe most common audio-over-network standard: dozens of channels of uncompressed digital audio down one ordinary Ethernet cable between Dante boxes. devices, a laptop, a wireless system, or a remote control app somewhere to talk to each other. It draws 5 watts at most, weighs next to nothing at 300 grams, and at $24 it's genuinely disposable enough to carry a spare. That price point tells you exactly what tier of rig this belongs in.

How it works in the path
Unmanaged means plug-and-play and nothing else. There is no web interface, no QoSQuality of Service — switch settings that let time-critical packets (like Dante’s clock) jump the queue ahead of bulk traffic. configuration, no VLANVirtual LAN — slicing one physical switch into separate isolated networks, like keeping Dante away from lighting and guest WiFi. tagging — the switch forwards traffic and that's the entire feature set. For a small DanteThe most common audio-over-network standard: dozens of channels of uncompressed digital audio down one ordinary Ethernet cable between Dante boxes. network carrying a handful of channels between a stageboxThe I/O endpoint on stage: mics plug in there and one digital line (AES50, Dante) carries everything to the console.

Keep your device count modest — think four to six Dante endpoints max — and this switch handles the job cleanly. The 100mm depth is genuinely short, which matters when rack real estate is tight.

The TL-SG108 is a tool for the right job, not a budget shortcut for a job that needs more.
In the rack
Details worth deciding before load-in.
This is a desktop unit, not a rackmount — you'll need a rack shelf or drawer to mount it cleanly. A half-rackThe standard slice of rack height: 1U = 1.75″. A 3U box takes three slices; half-rack gear pairs two units side by side in one. shelf paired with a small power strip keeps the footprint to one rack unit.
Use a short patch of colored electrical tape or a label maker on each port at load-in. With eight identical unlabeled RJ45s, tracing a loose cable in low stage light is slower than it needs to be.
Dedicate this switch to one function — either DanteThe most common audio-over-network standard: dozens of channels of uncompressed digital audio down one ordinary Ethernet cable between Dante boxes. audio or control network, not both. Mixing Dante multicastOne network stream delivered to many receivers at once — efficient for audio networks, but it needs IGMP snooping to stay polite. with laptop control and wireless management traffic on the same unmanaged switch removes your ability to troubleshoot cleanly if something misbehaves.
Power it from a switched outlet on your rack conditioner so it cycles cleanly with the rest of the rig. Leaving a network switch on while everything else reboots can cause devices to lock onto stale network state.

GS308The Netgear GS308 is another solid budget option for simple networking needs in a small audio rig. It provides eight gigabit ports in a metal desktop chassis that is compact enough to velcro inside a rack or place on a shelf. Like other unmanaged switches, it is plug-and-play with no configuration needed, making it ideal for basic device interconnection when you do not need advanced network management.View gear →
