If i correctly understood ur question then,the cable to be used depends on the devices.
connecting two ethernet port of two switches or two routers require cross cable and a router and switch require straight cable... :)

HI Korbenda, [Pls Rate if HELPS]
You should use Cross cable to connect the router back to back.
Normally the parameter in configuration includes are:
>>ip address
>>bandwidth
>>speed settings
>>duplex settings
Pls Rate if HELPS

It is not mandatory to have an IP address on the ethernet interface for it to come up.
Make sure the interfaces are not administratively shutdown as they are by default.
As suggested above you may also try to change the speed and duplex settings and see if the port comes up
