Overview
Distributing 450 watts of continuous power across sixteen 2.5GBASE-T ports while servicing dual 10G SFP+ uplinks dictates rigorous thermal regulation and dedicated switching silicon. Operating with a 120 Gbps backplane and an 89.26 Mpps forwarding rate, the switch routes high-bandwidth 802.11be Wi-Fi 7 access points and PTZ surveillance cameras without oversubscribing internal buses. Its power architecture leverages IEEE 802.3bt Type 4 PoE++, supplying up to 95 watts per port alongside essential fail-safes such as Perpetual PoE and PoE Alive Check to sustain connected nodes through administrative reboots.
The physical implementation relies on a standard 1U metal rackmount enclosure measuring 17.32 x 9.84 x 1.73 in (440 x 250 x 44 mm) and weighing 8.3 lbs (3.77 kg). Cooling a dense internal power supply and high-wattage PoE rails demands active airflow, which is handled by three internal smart fans. Under load, these fans generate an acoustic signature peaking at 56.6 dBA, making the unit strictly suited for dedicated equipment closets or server racks rather than noise-sensitive office desks. Operating temperatures span 23 to 122°F (-5 to 50°C), backed by a 788,000-hour MTBF at 25°C.
Management is anchored by an accessible web-based GUI offering Layer 2+ capabilities, including 802.1Q VLANs, Link Aggregation (LACP), QoS traffic shaping, and IGMP snooping. While integration with TRENDnet Hive enables multi-site cloud monitoring, advanced remote administration tiers incur recurring subscription licensing. Firmware updates focus on stability and security patches, providing a dependable, set-and-forget multi-gigabit core for commercial edge environments.
