Sadly, I only had a few minutes of time to spend on the FieldsNet server today. I did receive the optical drive and installed it. I connected a keyboard, monitor, and power cord and turned the machine on....
I saw that the motherboard light came on, the power supply fan kicked in, all three hard drives spun up, but no beeps and no image on the monitor.
I turned the machine off and verified that all of the cables were seated properly, again. I turned the machine back on and the same thing occurred.
Unfortunately, I had to go do other things this evening so I will continue debugging the situation tomorrow.
