I am using office desktop where I have the available NICs.
How can I setup?Here we have as usual DHCP configured.
How can you setup WHAT? The 'office desktop', or a DHCP server?
If you want the NIC's to get a DHCP address, configure the NIC to get one when you're building the system. Since you're using RHEL, you've got access to the RedHat knowledebase, since you're paying for it. Google also has many articles on how to set up NIC's in RHEL. RedHat has "system-config-network", so if you run that, you can set up your NIC's to use DHCP, instead of static addresses.
If you need to build a DHCP server, again, there are many how-tos on it.
