The drive bays are used to install 3.5-inch hot-swap drives. When you install drives, follow the order of the 
drive bay numbers. The EMI integrity and cooling of the server are protected by having all drive bays 
occupied. The vacant drive bays must be occupied by drive bay fillers or drive fillers.
Note: For 3.5-inch drive bay models that support NVMe drives, you can install up to eight NVMe drives in 
bays 0-3 and 4-7.
8  Foot stands
For tower form factor models, the foot stands help the server stand steadily.
