Sorry I misunderstood your question. Yes, the power distribution board (PDB) needs to be installed and 0G8CN is the correct part number. Instructions for installing/removing the PDB start on page 100 here: [URL]
Dear all, I own currently a second-hand Poweredge R420, with a non-redundant 550W power supply, 2 processors and 64 GB of memory. This power supply seems to be unable to accept more memory. I plan to change the non-redundant for two 550W redundant power supply units. I think that I need something mre than theses two units. I searched on google, looked many Youtube videos without success. Could you please give me some hints of address of documentation ? Thanks a lot Best regards H. Delebecque
