A recently purchased CSS610-8G-2S+ was shipped with SwOS Lite 2.13. After upgrading to 2.14, I noticed that an Apple Mac mini (Late 2012) with a Broadcom 57766-A1 Gigabit Ethernet controller can no longer establish a stable link with the switch. The link/speed LEDs are on for about 2 seconds, go out for about 2 seconds and this repeats forever. In the Link section of the web interface, I can see that the link disappears and reappears all the time. I cannot reach the Mac mini with 2.14 anymore. Using another port didn't help nor did a different ethernet cable.
Other devices weren't affected with 2.14. I downgraded to 2.13 and now I get a stable link with the Mac mini. So, it's quite obvious that 2.14 is causing this issue.
