How are you powering it?

[Weaver]

Janet has a DC power supply. Is that the good thing?

[burakkucat]

Stepwise --

• One end of a Cat5e Ethernet cable is plugged into the MikroTik SXT device.
• The other end of the Ethernet cable is plugged into the MikroTik power injector.
• The MikroTik PSU is plugged into the MikroTik power injector.
• The MikroTik PSU is plugged into the mains electricity supply.

As for the signal strength LEDs on the SXT, do the two attached images (cropped screen-scrapes from the YouTube installation video) help?

Next day edit: The attached images have now been deleted, as they have served their purpose.

Not sure how you supply a Poe device (48 v) with a DC PSU ?

Usually there will be a injector with ethernet and DC in and just ethernet out. Often these devices support passive PoE to allow this, it just injects it on specific wire pairs.

@Weaver what power supply are you using for the RBPOE?

[Weaver]

Janet reminds me that she has already plugged the PoE injector in. I’ll send a photo. We’ve used PoE injectors before.

[meritez]

I'm aware that you may have used Passive POE injectors before, what is the voltage on the DC power supply as the flashing ethernet green LEDs and flashing signal strength are indicative of a lack of voltage, Mikrotik recommend at least 18v to power the RBPOE.

Sorry for the confusion. :-) I’m pretty sure that Janet didn’t use a random PSU, because she managed to help me get to the office across the landing from my bedroom and I supervised while she put things together. Did you include a PSU in the box with the SXT? I don’t recall going digging for PSUs. I can take photos of course. And we can measure the voltage.

Yes there was one in the box, I'm concerned it's not outputting the correct voltage, can we have photos.

[Weaver]

I don’t think I can photograph the PSU because of the black shiny reflective black-on-black lettering. It says: Output: 24V @ 800mA ; Input 100-240 V 50/60 Hz; Model: C[?]ullPower SAW30-240-0800G. It has the wrong type of mains plug on it, not a UK mains three-pin plug, but a twin-round plug.

A quick search finds --

MIKROTIK 24V 1.2A PSU for RouterBoard products, UK type

The SXT was purchased from the Republic of Ireland, I've never used that power supply as I have a mikrotik rb750up:

I can hunt down a UK power supply, there £9 new on eBay with a rbgpoe adapter:

A good price for the identical model PSU to that which I found (and with a PoE injector included).

[Weaver]

We just put a foreign-to-uk plug adaptor in, which we had in stock anyway. Do you think this PSU is the bad thing then guys?
