Chosen Solution

Hi again, Dan. Since I do not need to go down to the blade level since that should be the only SSD installed in my unit, I suspect I can omit Steps 24-30 and 33-45… In other words only perform those steps necessary to access the HDD area so I can add the new drive, bumper units, and cable. However, since there isn’t an existing SATA cable in the unit, is it obvious where the end plugs into on a board, and if so, do I need to perform some or all of steps 24-30 and 33-45 to access that? I was hoping for minimally invasive surgery here, but if I need to go deeper to plug in the cable I understand. Thanks—Don

You’ll need to lift the logic board so you can reach under it to get to the cable headers
