[POE一問] HP 1820-8G Switch + UBNT UniFi UAP-AC-LITE

想問下HP 1820-8G Switch個POE port岩唔岩用黎駁UBNT UniFi UAP-AC-LITE? 係唔係一條LAN線就傳到電同data? 我見有分Passive POE同POE+, 唔知有乜分別所以想問下.

Thanks!

Short Ans: They are NOT the same thing

The most common PoE today is standards-based IEEE 802.3af and 802.3at PoE—802.2af provides power up to 15 watts per port and 802.3at provides up to 25 watts per port to support higher-powered devices. 802.3at is backwards compatible with 802.3af.

But in addition to standards-based power over Ethernet, there are other methods for delivering power over data lines, including legacy proprietary PoE, high-wattage PoE, and passive PoE. Different kinds of power over Ethernet are not interchangeable, and you may damage a device by connecting it to the wrong kind of PSE.

隻 switch support PoE+, 即係 802.3at, 要 AC PRO 或 AC EDU 先 support.

如果我無理解錯誤, C-HING 想由HP SWITCH 供電給UBNT UniFi UAP?
但HP 只是被動POE 供電.所以如以上的方案是不可以.
