2.5G Ports

Equipped with eight 2.5GBASE-T RJ45 ports that provide ultra-fast speeds capable of up to 2.5Gbps over existing Cat5e or better cabling.

Two black TRENDnet networking devices are displayed mounted on a wall on a light blue to white gradient background. The smaller device on the left has eight visible ports, while the larger one on the right features two external antennas and multiple top-facing ports, with a blue line connecting both units to suggest interaction or data flow.

Wall Mountable

The 2.5G switch features a durable metal housing with a convenient wall mountable design for greater installation flexibility.

A black TRENDnet 2.5G switch model TEG-S381 is displayed against a blue gradient backdrop. The device features multiple LED indicators labeled for power, port numbers, link status, and data speed. A white speech bubble with a crossed-out fan icon appears above, suggesting silent, fanless operation.

Fanless

The fanless design of the 2.5G switch lowers energy consumption costs and eliminates operating noise.
