Network switch for multi-gigabit LANs

The TRENDnet TEG-S381 provides eight 2.5GBASE-T RJ45 ports so desktops, NAS units and game consoles can run at 2.5Gbps over existing Cat5e cabling. It delivers a 40Gbps switching capacity and supports jumbo frames up to 9216 bytes for high-throughput workloads.

Fanless thermal design and silent operation

A fanless metal enclosure removes moving parts, so the switch runs without audible noise and reduces energy draw. The passive cooling handles the 2.5G traffic load in typical desktop or wall-mounted installations.

Desktop or wall-mount deployment flexibility

The compact metal housing includes keyhole slots for wall mounting and rubber feet for bench use, fitting into tight wiring cabinets or open shelves. Eight RJ45 ports free uplink capacity for 100M, 1G and 2.5G devices without requiring a managed configuration. Builders needing Power over Ethernet or SFP uplinks should look elsewhere.

Questions about this item

How do I mount the TEG-S381 switch on a wall without blocking the 2.5G RJ45 ports?

Use the built-in mounting holes on the metal housing; keep the unit oriented so the eight RJ45 ports face downward or sideways for cable clearance.

What component will need attention first on the fanless TEG-S381 after years of continuous operation?

The internal power supply is the only moving-part-free component that can degrade; plan to replace the switch if power delivery becomes unstable.

At what throughput does the 40Gbps switching capacity of the TEG-S381 become the limiting factor under sustained load?

When aggregate traffic across all eight 2.5G ports exceeds 40Gbps, the switch fabric becomes the bottleneck.
