Continuous beeping is usually the RAID card telling you your raid is degraded or rebuilding. (ie a 1 or more HDD has failed)
Amber LED is telling you the mother board BMC has logged a serious error message to the SEL log.
You need to down load the SELView tool for you system and check what errors are getting logged.
The SEL will contain many normal events, but anything that is flag CRITICAL needs to be resoved.
