Don't upgrade to SwOS 2.4!!!! (CRS326)

Fri Sep 15, 2017 2:24 pm

Hello. We've found a VERY CRITICAL failure on CRS326-24G-2S+

It happens with differents CRS326 and also with different SFP+ module (isn't a hardware failure)

SFP+ module: Ubiquiti UF-MM-10G (either in slot 1 or slot 2)
Software version: SwOS 2.4
Configuration: None (out of the box)

When you connect the fiber to any 10gbps equipment, it reboots ad infinitum (we've tried CCR1072, CCR1016-12S and HP Proliant with x520 card).

SwOS 2.0p: Works "without problem"
RouterOS (any version): Works "without problem"
SwOS 2.4: Boot loop

It was working "fine" with SwOS, but when we upgraded it, all ports went down.

900km and 10 hours to replace it with TP-Link switch.

Thanks MikroTik
