2 3 Optical-drive bay
Depending on the model, the server might come with an optical drive or a tape 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. Some
models have a secondary optical drive installed.
4 5 3.5-inch hot-swap drive bays
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.
