[WGSW-28040 / WGSW-28040P / WGSW-284040P4] Why 100Base-FX SFP transceiver can not work smooth with WGSW-28040 / WGSW-28040P / WGSW-28040P4?

The WGSW-28040 / WGSW-28040P / WGSW-28040P4 support SFP type auto-detection. However, some of the SFP transceiver can not report the type information at the moment of plug into the slot or some of the switch can not support auto-negotiation function for fiber port. As a result, WGSW-28040 / WGSW-28040P / WGSW-28040P4 could encounter the detection / synchronization issue and can not runs smoothly.
In such circumstance, we would suggest to pre-setup the port(s) that is going to attach 100Base-FX SFP transceiver to 100 Force mode in the Web page (as figure below), that shall make the connection error free.
Note: Hardware Version 2 only.
