Multiple Interfaces Issue

I have PowerEdge 4600 running Redhat 7.3, factory installation.
The system came with two embedded NICs, a 10/100 and 10/100/1000. There is also
an additional NIC (external) INTEL PRO100S.
My ifcfg-eth0 is as follows:
All I need is to configure another NIC with this address: 10.10.10.6
Sounds pretty straight forward but I am not able to make it work ...
Here is the problem:
I copy ifcfg-eth0 to ifcfg-eth1 and edit it appropriately. As soon as I do a
restart or do /etc/init.d/network restart , I lose one of the IP addresses. For
example, I will only be able to ping 10.10.10.5 and not 10.10.10.6
I have tried everything that I can think off, including disabling both the
embedded NICs and attempting to sub-interface eth0 to eth0 and eth0:0 with no
success. Depending on the combination of things, 10.10.10.5 works but not
10.10.10.6 or vice versa or nothing at all ... Both NICs are on the same
Can anyone please give me a hint?
I have another PowerEdge 6400 with 6 interfaces and everything is running fine.
The only difference between the two systems is that the 6400 is running 7.1
Is it a Redhat issue? hardware issue? or am I missing something?
This is my first post so I apologize if I left out anything.
Thank you so much for any help
