Hi,
i have 2 css326 connected through SFP with a hex S
hexS-> SFP1(switch1), SFP2(switch1)->SFP1(switch2)
i use 2 fiber patch cords and i can see all of them on winbox. all seem to work ok
when i move them to the site for installation both css disappear from winbox. i can see them on the dchp list, neighbor list, log in the web gui just fine. after refreshing 1 might come up.
the site fibers are 40 and 60 meters long. all SFPs are S-31DLC20D.
any ideas why this might be happening?
