Hi!
I have one RB260GS and one RB260GSP.
SFP modules GigaLink (1Gb).
All SFP modules is ok on my RB2011, CRS212 and other devices.
RB260GSP - SFP socket not work after upgrade to 1.17.
RB260GS was ok about 8 month and was in production, few days ago I want to change RB260GS to RB2011 to increase LAN ports. I switch off RB260GS, push reset, switch it on, and SFP not work yet!
I was tryed upgrade and downgrade firmwares on boths RB260, tryed upgrade firmware over BOOTP, different SFP modules, different optic cords, different second side devices. No results.
SFP led is ON, but second device no link.
All values in SFP-state page is freeze.
Screenshot is actual for both RB260.
Have ideas?

Contact support, providing all the possible details.
I also experienced troubles upgrading two RB260s to 1.17 (in my case they were GS units.) See http://forum.mikrotik.com/t/bricked-two-rb260s-upgrading-to-swos-1-17/107165/1
Judging anecdotally from these reports I think there is a real problem with 1.17 on certain RB260s (I had no problems upgrading RB250s to it.) To be on the safe side I’ve decided to skip that release for my other RB260s.
