Sorry, I don't understand your question and I don't know you machine either. The one picture I found tells me nothing!
You have the number for the cable/card assembly, is it the cable of this assembly that you need replaced?
What is this panel, where is it, can you give me a link with a picture? Is that a PCI card?
Is this optical drive internal or external?
First side of WHAT, the cable or the panel?
Where is this blue panel?
You need to be more specific with all these hundreds of different machines.
