TRENDnet TPE-2840WS 28-port Gigabit Web Smart PoE+ network switch

28-Port Gigabit Web Smart PoE+ Switch

The TRENDnet TPE-2840WS is a managed network switch built for small-to-medium business deployments that require both data connectivity and Power over Ethernet. It provides 24 Gigabit RJ-45 ports with PoE support and four shared Gigabit ports usable as either RJ-45 or SFP uplinks. A 185 W PoE budget powers IP cameras, wireless access points and VoIP phones through a single cable. The web-based GUI simplifies configuration for IT teams without dedicated network engineers.

PoE Budget and Port Power Limits

The switch delivers up to 30 W on the first four ports under the 802.3at standard and up to 15.4 W on the remaining twenty ports under 802.3af. Total simultaneous draw cannot exceed the 185 W budget, so high-power devices must be planned across ports 1-4. The shared uplink ports accept either copper or fibre SFP modules but not both at once, limiting uplink flexibility to four Gigabit links total. Smart fans adjust speed to reduce energy consumption while maintaining the operating range of -5 °C to 50 °C.

185 Watt PoE Budget Decides Fit

The single specification that determines suitability is the 185 W PoE power budget. Add the maximum draw of every powered device you intend to connect; if the sum exceeds 185 W this switch cannot support the deployment. Buyers who need more PoE capacity or higher per-port power must select a model with a larger budget. The 56 Gbps switching capacity and 16 K MAC address table handle typical SMB traffic loads within that constraint.
