It depends on your setup and what type of remote management you have. If you have IPMI then you can connect to the IPMI console and using netboot you can load the system that way.
Another way is to use Netboot and use either Kickstart or Preseed to install the system.
Finally if you have DRAC or iLO then you can use the remote device abilities of those system to share over the network your local cdrom. I have not used that but I have used preseed and kickstart to install systems many times. I use preseed so I can just start up a machine for testing very quickly. My VM's are very weak so it takes a while for me to install a VM. But I come back to a fully working system to customize as needed.
