LINOVISION 8 Ports Full Gigabit PoE++ Switch, Built-in 120W Power with 4 BT 90W Ports & 4 at 30W Ports, Sufficient for All IEEE 802.3 af/at/bt Devices Including PTZ Cameras, AP, PoE Light...

4 BT 90W PoE++ - Port 1-4 support BT 90W output, sufficient power for all IEEE 802.3 af/at/bt PoE devices in the market, including IP cameras, PTZ cameras, AP, VoIP phone, PoE light, PoE monitor, etc. (Total PoE budget is 120W) ^^ Full Gigabit - Provides 4* 10/100/1000Mbps PoE++ ports, 4* 10/100/1000Mbps PoE+ ports, 2* 1000Mbps RJ45 and 1* Gigabit SFP Uplink port. ^^ 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 over loading, and do not provide power to non-PoE devices to avoid damaging. ^^ PoE Extend Mode - Enable 820ft long distance PoE transmission with the trade off 10Mbps reduced bandwidth, great for IP cameras cabling, as most cameras consumes less than 10Mbps bandwidth. ^^ Plug and Play - No configuration is required. It will automatically work at correct mode when connecting to PoE/PoE+/PoE++ devices. ^^ Solid Design - Full metal enclosure with fanless design, 9.76 '' x 6.22 '' x 1.75 '' (248mm x 158mm x 44.5 mm), built-in 120W 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.
