8-Port Gigabit PoE+ Switch

The TRENDnet TPE-TG81g is an unmanaged network switch designed for small business or branch-office deployments. It combines eight Gigabit RJ45 ports with Power over Ethernet Plus so that access points, IP cameras and VoIP phones receive both data and power over a single cable. A fanless metal chassis allows silent operation in noise-sensitive environments.

110 W PoE+ Power Budget

The switch delivers up to 30 W per port while the total PoE budget is capped at 110 W. Auto-sensing IEEE 802.3at and 802.3af compliance means higher-power devices draw 30 W, standard PoE devices draw 15 W, and non-PoE gear receives data only. This budget dictates how many powered endpoints can run simultaneously.

Three Full-Power PoE+ Devices

With the 110 W budget the switch comfortably handles three 30 W PoE+ devices such as PTZ cameras or high-power wireless access points. Connecting a fourth 30 W device would exceed the limit, so deployments needing more simultaneous high-power ports require a switch with a larger budget. Lower-power 15 W devices can fill the remaining ports up to the same ceiling.

Questions about this item

How many PoE+ devices can run at the full 30 W per port with the 110 W total power budget?

Up to three PoE+ devices can draw 30 W each; the remaining ports supply up to 15 W for standard PoE or data only.

Which IEEE standards limit the maximum speed and power delivery on the eight RJ45 ports?

The ports comply with IEEE 802.3ab for 1000 Mbps data and IEEE 802.3at for up to 30 W PoE+ per port.

What are the physical dimensions and weight for rack mounting this switch?

The metal chassis measures 10.5" x 6.3" x 1.7" and weighs 3 lbs, fitting a standard rack shelf or brackets.
