Chateau 5G no PoE support?

Hardware MikroTik hardware general

Can’t find any information about PoE support for Chateau 5G* modem (RBD53G-5HacD2HnD-TC&RG502Q-EA).
I assume it doesn’t accept just one ethernet cable as a power source (no mention of PoE-out or PoE at all) so the power and data needs to be split into separate connectors.
Also it shows ‘bad command name poe (line 1 column 20)’ when entering “interface ethernet poe settings” in the terminal.

If I power it this way, by using a Gigabit PoE injector and Gigabit PoE splitter at the other end, would I still be able achieve close to 1000 Mbps speeds? Isn’t it going to cause some unwanted crosstalk interference between twisted pairs in the cable and in the device if Mikrotik doesn’t have a dedicated PoE for this?

Thing I noticed also, is for some reason Mikrotik doesn’t produce PoE splitters like the one I posted above, only injectors. So, is powering device this way (without dedicated PoE support) not recommended?

The device only supports DC jack power.
For tough to place locations, I suggest DC cable extender like this https://www.aliexpress.com/item/4000958018795.html

Thanks. That’s a good idea.

You suggest a cable, including manufacturing, seller markup, and merchant fees, that sells for AU$1.23?

@RogerWilco that sounds reasonable for a wholesale price from China for the short cable. If you look there’s longer options and the price increases reasonably and probably an OK constructed cable from the description. Perfectly fine for running a single router, but if your putting a heavy load on the end (poe router powering multiple devices) I would be much more concerned about the wire size and rating (would probably choose a different cable or make one for higher loads).

I use that particular cable myself. It is high quality from what I can tell and it serves me well. You can probably get the same identical cable for 15EUR from Amazon, up to you :slight_smile:

Hi Normis,

Deeply sorry to re-ask the question.

Like, the first user I would like to power my chateau from poe.

I fully aware that there is no POE in the device.

The question is can i use a POE 12 V splitter to accomplish the same as a DC Jack ?

for example :

This is just an example of a possible poe splitter.

@Imeira
The one you posted is not a “plain” splitter, it is a splitter and converter.

The Chateau 5G power requirements:
https://mikrotik.com/product/chateau_5g
Number of DC inputs 1 (DC jack)
DC jack input Voltage 12-28 V
Max power consumption 23 W
Max power consumption without attachments 17 W

Since it runs fine on up to 28V, it would be better (it depends on the power supply/other equipment you have) to use 24V (passive PoE) and a “plain” splitter.
If you need to use 48V or PoE 802.3 at, it would be as well advisable a splitter and converter at 24V, there will be less power dispersed in the conversion.
