hebn connecting to the VC Enet module, make sure tio use the VC Enet Administrator password from the tag on the VC Enet module.
The VC FC module does not have a CLI and will give an "access denied" if you try to connect to it. You should login to the OA and use the command "connect interconnect 3" or " connect interconnect 4" and attempt a login from there.
Dependiong on the firmware version youi may be able to login then.
