Hard disk drive activity LED:
On some server models, each hot-swap hard disk
drive has an activity LED. When this LED is flashing, it indicates that the drive is in
use.
Hard disk drive status LED:
On some server models, each hot-swap hard disk
drive has a status LED. When this LED is lit continuously, that individual drive is
faulty. When the drive is connected to the integrated SAS controller with RAID
capabilities, a flashing status LED indicates that the drive is a secondary drive in a
mirrored pair and the drive is being synchronized.
USB connectors:
Connect USB devices to these connectors.
DVD-eject button:
