Virtual Chassis with two EX2200 no network access at backup switch

Hi all,

I configured a Virtual Chassis with two EX2200 switches. The master switch was already in use and I added the backup switch to the rack. I have used the uplink ports 0 and 1 at both switches to connect them.

After the configuration everything looks fine, but if I connect a PC to the backup switch, I get no network connection. Currently only the master is connected to the rest of the network.

I configured the Virtual Chassis with a non-provisioned configuration file.

Did anybody have an idea why the backup switch did get a connection to the network.

Thanks
