Front components overview
Drive bays
The drive bays on the front and rear of your server are designed for hot-swap drives. The number of the
installed drives in your server varies by model. When you install drives, follow the order of the drive bay
numbers.
Drive bay filler
The drive bay filler is used to cover a vacant drive bay. 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.
Drive LEDs
Each hot-swap drive comes with an activity LED and status LED and the signals are controlled by the
backplanes. Different colors and speeds indicate different activities or status of the drive. The following
illustration shows the LEDs on a hard disk drive or solid-state drive.
