LINOVISION 24 Ports L2 Managed PoE Switch, Full Gigabit PoE++ Switch, Built-in 370W Power with 4* BT 90W & 20* AT 30W Ports, Sufficient for All IEEE 802.3 af/at/bt Devices, Supports QoS, VLAN, IGMP...

4 BT 90W PoE++ - Port 1-4 support BT 90W output, sufficient power for all IEEE 802.3af/at/bt PoE devices in the market, including IP cameras, PTZ cameras, AP, VoIP phone, PoE light, PoE monitor, etc. (Total PoE budget is 370W)
Built-in 370W PoE Power - Maximum 370W high output power with 4* BT 90W Ports and 20* AT 30W Ports. It can support multiple high-power PoE devices, such as PTZ cameras, PoE lights, AP...
Full Gigabit - Provides 4* 10/100/1000Mbps PoE++ ports, 20* 10/100/1000Mbps PoE+ ports, 4* Combo Ports. Each Combo Port comes with one RJ45 port and one SFP port, you can select either port in each pair based on your network requirements, but not both simultaneously.
L2 Managed - Supports L2 management functions like VLAN, QoS, ACL and PoE control (turn On/Off PoE). It can be managed via WEB, CLI or SNMP.
Top Safety for all PoE and non-PoE Devices - With standard PoE design, it follows 4 steps of PoE power up process (PD Detection -> PoE Power Classification negotiation -> Start up -> Power ON), it supplies proper power to 802.af / at / bt devices to prevent overloading, and do not provide power to non-PoE devices to avoid damaging.
Solid Design - Full metal enclosure, 17.32'' x 11.42'' x 1.75'' (440mm x 290mm x 44.5mm), built-in 370W power, ideal for both home and commercial environments.
Important - The term "PoE++" doesn't have a unified standard and doesn't completely correspond to the IEEE 802.3 bt protocol. Please confirm whether your "PoE++" PD device is also an IEEE 802.3 bt device. If so, they can work well. If not, there may be issues with proper operation.
