This is a special PoE Switch with 24V DC out, it can not Compatible with 802.3af(48v). It could work only on some special customized 24V PoE device
<br />please confirm your device is using DC 24v PoE before you purchase this PoE Switch.
<br />If you can not figure out the PoE voltage of your device, we suggest you to buy 48v PoE Switch which can follow 802.3af agreement.
<br />
<br />This is an Passive Power Over Ethernet of 9 port 10 / 100Mbps-T Ethernet switches, including 8 unsolicited PoE Ethernet ports and 1 Uplink ports. With an external 110V-240VAC to 24VDC power supply adapter, any one of the 8 port can provide output power, each Ethernet port can provide network transmission speeds of up to 10 / 100Mbps , with Cat5 / 5e / 6 network cable.
<br />
<br />Which do not compatible with IEEE 802.3af and IEEE 802.3at, this is an unusual non-standard 24V unsolicited Power Over Ethernet switch. It supplies power NO MATTER WHAT, so don't plug the "PoE 2X~PoE 9X" side into anything that isn't ready for it.
<br />
<br />This POE switch only support 10/100M connection, do not support gigabit ethernet connection, because  "PoE 2X~PoE 9X" port using 4,5,7,8 pin as power transfer, Please do not connect any gigabit ethernet device on "PoE 2X~PoE 9X" port, this will damage your device.
<br />
<br />Gigabit(10/100/1000Mbps) ethernet Uplink device can only access "1x" port, Please do not access "PoE 2X~ PoE 9X", this will damage your device.
<br />
<br />Please do not connect any IEEE 802.3at Powered Device to "PoE 2X~PoE 9X" port, this will damage your device.
