Hi folks, so I upgraded in 2021 to an RB5009 for 2.5Gb/s support from my PC to my server which is on 10Gb/s. Ergo, my PC is on ether1 and the server is on sfp-sfpplus1 (10Gb/s via DAC)
Whenever I upgrade RouterOS, the RB5009 fails to complete the boot process if my PC is connected to ether1. It sits there - forever - with a dim LED on port 2 but no other lights other than the blue power LED. As soon as I remove my PC from ether1, the boot process completes. I can then reconnect to ether1 and the router stays up (until next reboot).
Has anyone seen this behaviour? I have searched for this issue and I can't find it, but perhaps my search terms are wrong.
