DELL R710 - 2 network cards out of 4, if active cannot be seen at the LAN

Hello All

I have a server R710 and it has 4 network cards on it.

I have deactivated 2 out of the 4 network cards that come from the manufacture and for the other 2 the configuration is as follows:

Network Card 1: 192.168.1.228 / 255.255.255.0, GW: 192.168.1.1, DNS: 192.168.1.224

Network Card 2: 192.168.10.8 / 255.255.0.0, GW: nothing. DNS 192.168.10.4

The thing is that if i will restart the server i cannot find it in the LAN. in any of the 2 LANS. I have to disable and then enable the Network Card 1 and after it can be seen to any of the 2 LANS.

I have another 4 Dell servers (3 R710, 1 R610) and that dont happen to them.

Any ideas?

Thx in advance
