Hi,
The Voltaire ISR9024D is an unmanaged switch so a console cable will not work.The I2C port is for factory use only for direct interogation/programing of internal devices off the I2c buss.In sort there is no configuration needed on this switch.All you need is to connect it to a host or switch that can run a SM (subnet manager) that can assign and initialize the links on it and any host connected to it.Hope this helps
