This switch is a high performance Layer 2 managed switch with 52 Gbps switching capacity. It provides (24) 10/100/1000Mbps copper ports with IEEE 802.3bt PoE++ capability and (2) additional 100/1000Mbps dual speed SFP/RJ-45 combo ports. The SM24TBT2DPB complies with the latest IEEE 802.3bt PoE++ standard and supplies up to 90 Watts per port. It can provide full PoE++ output on all 24 ports when equipped with the dual hot-swappable PS-ACDC-1200 power supplies. The SM24TBT2DPB can be powered by low-line and high-line AC or DC power and Digital Electricity*, making it ideal for use in a wide variety of building applications.
