No network over fiber using transceivers (SFP) in a combo switch

Just be careful not to use the uplink Combo ports of the same numbering for RJ45 and with SFP and when connecting the SFP and with the fiber connected.

Turning the switches off and back on again will start the SFP in use, otherwise the switches will have activated the RJ45 port and not the SFP at startup.

We also have to notice that the hose is prefabricated and what goes from A on one side, enters B on the other and vice versa. It is important to ensure this on the fibre cabling, as they will not work if it is laid from A to A and from B to B.
