Poweredge vrtx i/o module configuration

Hi,

I am working on a Dell Poweredge VRTX and trying to connect the blades to the outer switch.

The model of the switch (VRTX 1Gb R1-2401 switch module) with p/n:<ADMIN NOTE: Service tag removed as per privacy policy>

When you check the network adapters on blade servers it shows connected but cannot pick up an IP on my DHCP network.

Kindly assist.
