CARLOSAGU,   W1GCR is indeed supported in the R540, but oddly isn't showing compatible with the R710 you were referring to previously.    Let me know if this helps.  
Hi, we bought DUAL PORT NIC BASE T model W1GCR , chipset Broadcom BCM-957810A 1008G for PowerEdge 710 and 720 servers... But we migrated many to R540 .. Is this NIC compatible with R540? I know that the slots of r540 are low profile.. but the r540 has a NIC of 1GB the same length.. so I think if I could use this slot...or not..?  and I need to know if it is compatible or not... Thanks Carlos
