I am using a COM Type 10 module that contains an i210 Ethernet controller. I'm designing a carrier board for this COM module and I desire to configure the i210 as a 100/10 Mb only controller.
Therefore, the MDI2 and MID3 differential pairs will not be used, only the MDI0/1. Is it OK to leave these pins unconnected? If not what is the preferred method for terminating them.
Also, with the i210 controller, it is possible to 'turn-off' the gigabit mode and it will be configured as a 100/10 Mb controller. How is this done?
Is there an external software configuration tool used to do this? If so, what is the name of this tool?
Any help that you can offer would be appreciated.
Thanks
Jim
