4 Optical-drive bays 1-2

Depending on the model, the server might come with an optical drive installed in the lower 5.25-inch optical-drive bay. The upper 5.25-inch optical-drive bay is for a secondary optical drive or a tape drive. Some models have a secondary optical drive or a tape drive installed.

5 6 7 3.5-inch drive bays

The drive bays are used to install 3.5-inch 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, up to twelve NVMe drives can be stalled in bays 0-3, 4-7, and 8-11.

8 Foot stands

For tower form factor models, the foot stands help the server stand steadily.
