When we boot up SYS-120C-TR (X12DDW-A6, BIOS 1.1) through iPXE (iPXE.EFI). the system just locked up during iPXE initializing. We reboot the system several times, the end result is the same.
Is the system capable of booting up from iPXE or not?
First, make sure you have "Host Interface" enabled in the BMC settings. If you disabled Host Interface, it will cause system lockup during iPXE boot. If you have to have "Host Interface" disabled which we don't recommended to do so, then you will need to use SNPONLY.EFI protocol for iPXE to work. iPXE images can be downloaded from this link
