The server you are looking support for is end of interactive support but as a general recommendation please test the board without the memory installed looking for beep codes. Also please keep in mind that the amber LED on the fans means that either the fans or the connectors on the board are defective.
Thanks for the suggestion. We tried booting the server today without the memory but it still won't POST and there are no beep codes heard.
We ordered new fans so we will see if anything changes once the replacement fans arrive.
