Hello, I am new here and came to ask a stupid question.
I simply do not know whether my new unit is to be RMA or is that normal:

Yesterday I did purchase RB260GSP, and there was firmware 1.12 in it, working ok.
I experienced power drops each few minutes trying to use PoE, so went upgrading firmware.
Well, Rb went dead right after clicking Upgrade (RED light for port 2 and 3 blink shortly, then everything go dark).

Well, I setup bootp/tftp server and hold the button, it did load a file, but no success..

Then I managed to download 1.12, 1.13 and finally 1.11 firmwares from mikrotik site (just edit filename in adress..).
Version 1.12 do load (either from tftp as a rescue, either after device gets alive using web Upgrade).
NONE of versions 1.11 (just an attempt..), 1,13 or 1,14 do work.
Device is dead with each other than 1.12 - regardless of whether firmware was submitted using tftp or web.

Well, now I still own rb260gsp ver 1.12, working as a normal (non-PoE) switch, but having troubles with PoE,
and suspect it is somehow damaged as I can not upgrade firmware... I read that other users do use 1.14..
I tried to download file more times and compare to see whether it is not damaged by download, but files do equal.
BTW, could someone post MD5 checksum of the file 1.14 to be sure?

Is that NORMAL, and did anyone experience the same? I did searched a lot but found no such note.
Or, should i return it as RMA? I will get another one from the same seller and batch, will it help or not??

Hi,

i did not hear something like that in the past.

Please, pay attention, that you use the correct firmware:
http://download.mikrotik.com/swos/swos-rb260-1.14.lzb

MD5SUM should be: 07f7a963e4fc49f0139fb42458047ed7 swos-rb260-1.14.lzb

If this does not work, you should contact the support guys directly through email, as this is more a customer forum

HTH,
Ronny

thank you, MD5 of my file is Ok, file is correct one for 260..
Well the device is rb260gsp - with PoE, i was curious whether firmware should be different from non-PoE model or what..
Perhaps I may wait for swos 1.15, upto few weeks, and if it will not "fit" then I will try RMA.

Just a short message: I returned that switch and got new one as a replacement.
Now everything works as expected, with zero troubles, including PoE supply and fw upgrade to 1.14
So, thanks for replies, this was very strange behaviour to me (as it was working with 1.12),
but it seems to me that it was really just a bad piece.

edit: and after getting confident more and more, I tried SFP module that did not show in old rb260gsp correctly and did not work.
It was showing something like ýýýýýýýýýýýýýýýý instead of vendor and type.
Now the same SFP do work and shows right test
Vendor CISCO-FINISAR
Part Number GLC-SX-MM
(it was just a test, i use Mikrotik modules, but it clearly shows that there was something messed in that bad one).
