GS1500-24PoE for Ubiquti 12Volt WiFi
Accepted Solution
-
Answer is "simple": IEEE 802.3af compliance.Moreover, 44V is minimum available if necessary at the switch port, 57V is the maximum at the port, 350mA as top current. At the endpoint, minimum is 37V, same maximum.Long story short, if your current is not "that" high and the voltage is not triple or quadruple, the user device will take advantage of the higher voltage for lower the current drain. DC-powered HiFi amplifier can take advantage of +12/25% more voltage or 50-100% more current, with a switching power adapter, gaining better drive management for the speakers (more controlled basses). Some even more, but refer to the specs of the amplifier producer.Moreover, Ubiquiti declares compliance with 802.3af. If the AP get fried... IMVHO the AP producer should be questioned for reasons why happened.And no. I have no relations with Zyxel...

Specs sheet of GS1500-24P don't provide much details about PoE features...except "802.3af support". Which should mean that your AP should work if requires the same PoE specs (up to PoE Class 3)In case of PoE+ (802.3at/PoE Class 4) could not work...

Hi @Hun,
Just like mMontana said, GS1500-24P only support 802.3af.
If the Ubiquiti WiFi unit isn't a 802.3af PD, it can't be powered up by GS1500-24P.
May I know which model is your Ubiquiti WiFi unit?

Hello,
thanx for replying ..... I need to get up in the ceiling to find out what model I have..... Unfortunately I'm unable to get this info from the UNIFI controller..... Man, I wish I could power it it up from this switch.....
Thank you for now for your time!0 -

Unifi AP AC Lite
model is : UAP-AC-LITE
Input 24V 0.5A GigE PoE 802.3af Poe
So this means, it can't be powered up from my Zyxel?0 -

Datasheet says... 802.3af/AWhich i don't know if... your GS1500-24POE supports.@zyxel_melen could you please enlight some details about that?

Montana, sorry I'm not sure if I follow you on this.....what info should I provide you with....?
The data sheet says this:
Power Method 802.3af/A PoE 24V Passive PoE (Pairs 4, 5+; 7, 8 Return)

Hi @Hun,
The UniFi data sheet shows the Power Method 802.3af/A PoE 24V Passive PoE (Pairs 4, 5+; 7, 8 Return), which means this AP can be powered up by directly connecting to a PoE switch or powered up by connecting with a PoE injecter.
So, you can connect your AP to GS1500 directly since this AP is a 802.3af PD.

Great info!
Since the original injector supplies 24V and the switch port is capable of 48V, how is guaranteed that the AP wont get fried?
