hi

I have a ADSL router connected via straight-through patch cable to the managed switch PowerConnect 3324.
Both Ethernet devices (router & switch) are hard coded to 100FD.
At the switch I cannot use AUTO for MDI/MDIX.
AUTO MDI/MDIX I can use only by NIC AUTO-NEGOTIATION.

Should I enable MDI or MDIX on the switch in my case ?

Do I understand correctly ?
MDIX support cross-over cable
MDI support straight-through cable
