How to Make ICX7150 Unmanaged Switch

[Eric]

I tried latest firmware for Switch, as well as a firmware turn it to Router.

Not working. What I did was left it as default setting after upgraded firmware, then connect to network by a SFP cable, lights flushing. But the device connect to the switch cannot connect to network.

My question: is there a firmware to make ICX7150  unmanaged switch? Or is there some settings for the Switch Firmware to make it work like an unmanaged switch.

Thanks.
