I want to Stack two SG 350X-48P Switches using the 1000Base-SX MGBSX1 Modules in two different Rooms.
The Switches use the same Firmware and I've resetted the Slave-Switch according to the Stacking Troubleshooting guide provided by cisco and only configured the Stacking Ports. This worked without problems using copper cables for testing, but not with fibre.
The default subnet 192.168.1.0/24 is not existent on the master switch because its already configured to work with our network.
Is there something im missing? Is stacking not possible with those Modules? If I plug them into non-stackig Ports they establish a connection immediately.
