VNX5300 Control Station and Data Mover

Hi,

i'm trying to set up a VNX5300 system with one Control Station and one Data Mover.

I can ping the control station and both SP of VNX5300. (x.x.8.93 - x.x.8.94 - x.x.8.95)

I connected to Control Station trought SSH session and he show:

I think the problem is the connection between Control Station and Data mover.

I have wired following the diagram shown on the guide. I only have a doubt, connections between the ethernet ports use a normal cat.5e/6 ethernet cables or they are special cables?

Thanks
