POWER ATL_5G_R16 and SXT SQ 5ax

[vtzam]

Hello ,

I tried to power up these 2 devices with GPER14i without success. The ATL5G is power on properly but no luck with the SXT. Could you suggest any other poe splitter to do the job ?

Thanks in advance

You should provide us with a little bit more information. GPER14i should power both devices without a problem.

What are you using as your power supply ? Maybe your power supply doesn’t have enough power.

Did you check in SwOS if PoE is enabled on SXT port ?

What supply voltage are you using ?

All your devices supports up to 57V so I would suggest you that you use higher voltage if possible, especially if there are longer cable runs from GPER14i towards your devices.

GPER14i -> PoE out 802.3af/at <- this means * Active * 44-57 V, can be powered by both *Active * and * Passive * "high voltage" PoE or (still at 48 V or so) through the two power pins, see:

GPeRx4 and multiple VLANs

Hi The GPeRx4 arrived and I was able to test it. it can be powered by: PoE 802.3 (AF/AT and BT) Passive PoE, both 4 wires and 8 wires. I’ve even tested with a RBGPoE injector from Mikrotik with a 48V power supply and worked just fine. For PoE it needs at least 48V as input (passive or active, does not matter). It does not power on with 24V PoE. It does not come with a power supply. it runs SwitchOS Lite Lite. This means some of the features of SwOS Lite are missing: POE ports 2-4 can be …

ATL5G -> PoE in 802.3af/at <- this means * Active * 44-57 V BUT it accepts also * Passive * 12-56V

SXT SQ5 Ax-> PoE in * Passive* PoE in input Voltage 12-28 V <- do you see where the issue is?

You need to power the GPER14i with "high voltage" 802.3 at/af/bt PoE and something else that converts the PoE out (802.3af/at) to 24V or so to feed it into the SXT.

Google for (examples):
POE-CONV-4824G
PS5724AT-RJ
UQ-INS-8023AF-I-G

BUT these - usually - are not suitable for outdoor installation.

So, search for:
UQ-INS-3AF-O-G

Didn’t check the topic name… So as @jaclaz said, UQ-INS-3AF-O-G is a way to go IMHO, i use it all the time.

This make sense, so if i understand correct the UQ-INS-3AF-O-G needs to connect on the SXT poe in ,

Thanks for the reply ,

Yep.

It depends on your network topology, it could be placed near the GPER14i or near the SXT, if there is a long stretch of ethernet cable between the GPER14i and the SXT it is better to run 48V on the PoE, if it is within 20 m or so running it at 24V is fine as well.
