2530 (J9779A) Connections

Excuse the ignorance...


New to the networking industry and ive been thrown into completing a new installation. I need to connect 2 of the 2530 switches via  MM fiber. Both units are currently connected into the SFP port 27, however i am unable to Tx/Rx anything. I bow to your expertise.

Hello.  You have link up?  What kind of transceivers?

Also, if you could attach/paste the configs.

Are you getting link lights on the switch LEDs?


If not, you may need to put a X in the fiber - separate one end and patch them back in with the Tx / Rx swapped.
