M.2 drives
This section provides cable routing information for the M.2 drives.
M.2 drives can be installed on the standard air baffle (scenario 1), GPU air baffle (scenario 2), 2.5-inch middle 
drive cage (scenario 3), or 3.5-inch middle drive cage (scenario 4). The following illustration shows the cable 
connection for scenario 1. The cable connections for other scenarios are the same.
