[HELP] beginner asking for help about RB951ui-2HnD

Hy, 2 weeks ago i bought rb951ui-2HnD but when i plug a cable in the port 5. the LED yellow light turn on port 5 and on port 2 also. i dont plug cable on the port2.
its happen when i set the default config (port 2 as master, port 3,4,5 as slave) is it normal?i think its happen only when use maste/slave config. everytime i plug on the slave port, the master port led and slave port led turn on. the image is here https://ibb.co/hVzSpv

my question: is it normal for RB951ui-2HnD?

i hope u guys help me to get the answer, cuz when i ask in my country forum, my post is drowning no one answer that :frowning:
sorry for my bad english

Yes, it is normal because the master comes up with the slave port. Use bridge and it will not be mystically blinking…

thanks for reply my question. now i have no doubt about the LED does indeed identify a Master Port. im searching in the forum about my question, and the answer is positive there is no problem about my RB951ui-2HnD.

thanks for answering my bad question, hope this help others beginner.
