I have a 3560 V2 48port switch that is working in a live environment and has a transceiver connected into one of the two transceiver ports and is working without issue.
I am connecting a second fibre run to this switch. I have connected the transceiver with the fibre cable connected into the second transceiver port on the switch. However, I am seeing no activity at all. As I test I connected it into the currently working port and saw activity so I know the fibre run, fibre cable and transceiver are all functioning correctly. The issue seems to be with the second transceiver port.
Is this a fault or is this something that needs to be configured in order to 'enable' the second port.
