The CD drive is fairly easy to replace.  Try page 39 of the manual: [URL]
I recently booted up my PowerEdge 2600 and noticed that my cd drive was flashing. What does this mean? (I have no signal whatsoever in Ubuntu.) If it is broke, how would I go about replacing it? I'm very confused when it comes to the inside of this machine. SPECS: Ubuntu 12.04 LTS 32bit Xeon @ 2.8Ghz 3GB RAM   If you need more information, let me know.
