RB2011-UiAS-RM - switch2 group completely silent

Hello

I have the case on two different pieces of RB2011-UiAS-RM: I am unable to use any of the switch2 ports (eth6->eth10). When i plug a cable, no led, nothing, and of course no “R” on winbox. It just acts like all switch2 ports were not connected at all.
Of course, the same ethernet cable is OK on ports 1-5, negociating at 100Mbps full duplex. ROS 6.32.2, firmware 3.24, just hard-resetted.

Is there an hidden feature to enable/disable switch ports in ROS or is it just a failing device?

I have the same problem on RB2011-UiAS-2hnD - Anything plugged into ports 6-10 do not work. Did you ever find an answer?

yes and no.. Contact Mikrotik support, do some tests with them and get a RMA ticket to send the router back to Latvia.
