Overview
Provisioning 740 W of aggregate power across twenty-four 2.5GBASE-T ports alongside quad 10G SFP+ uplinks anchors this rackmount multi-gigabit platform directly into high-density network backbones. The switching fabric delivers 200 Gbps of non-blocking throughput with a 148.91 Mpps forwarding rate across a 32K MAC address table and 2 MB packet buffer. Supporting IEEE 802.3bt Type 3 and Type 4 PoE++, individual ports deliver up to 95 W to negotiate power-demanding hardware such as high-draw PTZ surveillance cameras, access control terminals, and high-performance Wi-Fi 6/7 access points. Power delivery is reinforced by integrated hardware safeguards, including Fast PoE to energize connected peripherals immediately upon boot, Perpetual PoE to sustain peripheral power during system restarts, and PoE Alive Check to automatically cycle unresponsive endpoint hardware.
Encased in a 1U galvanized metal chassis measuring 17.32 x 10.04 x 1.73 in (440 x 250 x 44 mm) and weighing 9.49 lbs (4.31 kg), the physical structure provides the rigid shielding and grounding required for high-current enterprise deployments. Thermal regulation is managed through an internal active cooling array utilizing smart variable-speed fans, maintaining safe component operation across an environmental window of 23°F to 122°F (-5°C to 50°C). With base power consumption rated at 57.16 W prior to PoE load distribution, the active fan curve dynamically responds to cumulative thermal loads, producing acoustic output that designates the unit specifically for server racks, telecommunication closets, or isolated equipment spaces rather than open-office environments.
Management operates via a comprehensive Web Smart interface alongside integration into the TRENDnet Hive cloud management ecosystem, delivering essential Layer 2+ capabilities such as 802.1Q VLAN, Voice VLAN, LACP link aggregation, QoS, IGMP snooping, and 802.1X port security. Long-term electrical endurance is reinforced by a calculated mean time between failures (MTBF) of 530,000 hours at 25°C. For network architects deploying dense multi-gigabit infrastructure, the integration of four 10G SFP+ cages ensures high-bandwidth uplinks without bottlenecks, establishing a resilient distribution platform that balances high PoE density with automated self-healing power controls.
