Mikrotik has done considerable harm to own reputation in the matter of CSS610-8G-2S+IN and CSS610-1Gi-7R-2S+OUT. The devices were put on sale with a non-production Release Candidate (2.12rc2) version of SwOS (SwitchOS) that cannot be seriously used and information about something like SwOS “Lite” very quietly appeared some time after CCS610 was released.

Answer: In the new RC versions (2.13) they already have a banner updated to “MikroTik SwOS Lite”
