how to combine nics for DM Multipath

I don't undestand how to combine 4 nics in order to use DM Multipath. Do I have to install each nic with its IP address? If yes, do I need a group IP address? This concept is not clear for me.

The connection beetwen the server (DELL Poweredge T710) and the SAN through iscsi works well, I used multipath but only one nic is configured with its IP address. But the server has 4 nics and I would combine them with multipath!

the devices are:
SAN DELL equallogic (3 nics)
DELL Poweredge T710 (4 nics)
2 switch 5424
