Desktop Gigabit switch for small networks

The TRENDnet TEG-S80G is an unmanaged 8-port Gigabit switch built for home offices and small businesses that need a simple wired upgrade. Eight RJ45 ports run at 10/100/1000Mbps and support jumbo frames up to 9KB. A 16 Gbps switching fabric handles full duplex traffic without blocking. Plug and play installation requires no configuration.

Fanless metal housing with GREENnet efficiency

The unit operates silently because it has no fan, relying on a sturdy metal case for passive cooling. GREENnet technology adjusts power per port based on link status and cable length, delivering up to 70% energy savings versus conventional designs. Maximum draw is 3.5 Watts from the included 5V DC adapter, which accepts 90-260V AC input. Operating temperature range is 0 to 40 degree Celsius.

16 Gbps switching capacity decides fit

The 16 Gbps non-blocking fabric is the single figure that determines whether this switch matches your throughput needs. It provides wire-speed forwarding across all eight Gigabit ports simultaneously. Networks that aggregate multiple 1 Gbps uplinks or run heavy local backup traffic should verify this capacity against their peak load before buying.

Questions about this item

How do I install the TEG-S80G and which step is often missed?

Connect the supplied 5V DC power adapter to a 90-260V AC outlet, then plug devices into the 8 RJ45 ports; the step often missed is allowing airflow around the fanless metal case so the 3.5W maximum consumption stays within the 0-40°C operating range.

What maintenance or replacement will the TEG-S80G need later?

No user-serviceable parts exist; keep the ventilation slots clear of dust and verify the power adapter continues to deliver 5V DC at 1A — if the adapter fails, replace it with an equivalent 5V 1A unit.

What limit appears first on the TEG-S80G under sustained heavy traffic?

The 16Gbps switching fabric and 256KB buffer handle wire-speed gigabit frames; the first bound reached is the 8K MAC address table, after which new source addresses cannot be learned until entries age out.
