I'm having a problem with a Scalance x101-1.

The network is as follow:

- one network card from pc1 is connected direct to a switch Scalance x108

- another network card from the same pc(pc1) is connected to Scalance x101-1

- Scalance x108 is connected to 2 fields device and works properly

- Scalance x101-1 fiber optic is connected to a cisco switch communicating with all the network (plc and other computers)

The led of the ethernet port seems to work properly (Led flashing green and yellow), the led of the fiber optyc stay always yellow. I can see from the fiber that the light is arriving from the other switch, but the X101-1 doesn't send nothing.

I tried to change configuration by the set button and work in ts mode but it didn't worked.

I tried to disconnect the ethernet cable from the secondary network card of the pc and connect it direct to the Scalance X108 and it didn't worked.

I tried to change the Scalance X101-1 with a new one and it didn't worked.

At the moment I pulled an ethernet cable from the Cisco switch direct to the Scalance X108, and I'm working without the Scalance X101-1.

Is there anyone that can help me pls?

Thank you
