SG350X-48P Stacking Issues

[jannes.hicken]

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.

Hi Sir,

My name is Puneet Sandel and I provide technical support on Cisco small business devices.

The SFP module model listed by you is fully compatible with the SG350 switch and the distance between 2 switches has to be less than 500m. However try using MGBLX1 SFP module with the switch.

Also it is not necessary to have the default subnet running on the device.

Kindly give us a call on the frontline team to get a case open with Cisco and we will definitely help you out with the troubleshooting as well as configuration.

Please check the link given below to contact Cisco frontline team.
