PSE-8 and PSE-24 boards

Hey folks,

Is it possible to buy PSE-8 or PSE-24 boards for PoE switches separately?
We have several switches that have various power problems on random ports due to surges, etc.. I was able to repair a couple by replacing the PSE boards from donor switches, but would like to just get some new ones.

Thanks in advance!

Ask directly MikroTik: sales@mikrotik.com

Did you ever find out if this were possible? Thanks!

Mikrotik sales told me that they don’t sell these boards individually :frowning:

Ugh, need a PSE-8 for a CRS112. Seems a shame. Only port 8 does not put out PoE correctly.

Hi Boardmembers:in :slight_smile:
so i have the same Question to PSE-24 can someone verify we can t get spare parts form mikrotik ? And on the other hand has someone repaired one ? And when yes please share where ! And if not who is interrested in repair ? So i will test a repair center for microelectronics to check if repair is possible .

Also need PSE-24

i try to repair this board. my board is from netpower 16P, only one port (port5) have problem cause lightning. In winbox there’s message about overload voltage to this port.

I find out theres short a diode and a resistor was burn on top side pcb, On bottom pcb there’s a Ic was burn. Some digging get the ic is from texas instrument TLV9002 (marking code 1GNX).
change diode and resistor and remove the ic. Leave ic not populated cause i don’t get replacement for this part. Try to fire up, but still get the overload message.

Move a working integrated component on that place, and if all is working on port 5, you miss only that component.

Interesting, I’ll try that on a few of my damaged boards. Also, as far as I can tell, they use the same boards in all switches, power connectors being the only difference. At least, PSE-8 and PSE-24 are nearly identical.

I did compare all pin for all active component (diode, transistor and ic). The value is the same in diode mode. I wish i can disabled the current and voltage sensor for this port, but it will be hard without schematic.

The PCB have mark code PSE-8, i think 8 have meaning 8 port. And sticker PSE-24 mean the poe have output 24V for code 2 and 48v for code 4.

PSE-8 means is meant for an 8-port switch, as you said, the CRS112-8P-4S. It has dual DC jacks that line up with the back of the case. PSE-24 is for the 24-port CRS328-24P-4S, without the DC jacks, but with an internal 4-pin connector instead. The 24-port switch uses 3 of these boards. I’m fairly certain the other switches use PSE-24 boards in various quantities.

PSE-8 have meaning the pcb have 8 channel poe, and the code PSE-24 have meaning the poe have dual output 24v and 48V.

All these boards are 8-channel, and all of them are 24/48V. This is why the PSE-8 has dual DC jacks.

stop usung useless quoting and use the button post reply or you create a useless mess…

i think quoting is useful to give context to an answer, i see it as a form or reply like any modern social media have today

It is completely useless when you reply to the post just above,
and if you consult the site from the phone it becomes a quote of quote that quote the quote of something already listed, all for nothing.
