Blank drive carriers, which may ﬁll some of the hard drive bays, follow the same
replacement procedure as hard drives. If you are replacing a blank carrier with a drive
module, be sure to keep the blank for possible future use. Blank drive carriers must be
installed in all empty drive bays to maintain proper airﬂow through the unit. Be careful not
to apply excessive pressure when installing the blank carriers.
No tools are required for this procedure.
Xserve/Xserve G5 includes one to four drive bays, and Xserve RAID includes fourteen
drive bays for Apple Drive Modules. The modules consist of hard drives attached to
carriers; they are removed from or installed in the server as a unit. You can replace hard
drives while the system is running; you do not need to shut down or open the unit ﬁrst.
There are two LED indicators on the front of each drive.
• The upper LED (Xserve) or right LED (Xserve RAID) shows drive status: a green light
indicates the drive is good; a yellow or red light indicates the drive should be replaced
or removed and reinserted.
• The lower LED (Xserve) or left LED (Xserve RAID) shows drive activity: when the light
is blinking, the system is reading from or writing to the drive. To avoid losing data,
never remove a drive when the lower or left LED is blinking.
1. If the hard drives are in the locked position (the yellow security LED on the front panel
is on), use the Allen key that came with the system to unlock them.
Drives must be in the unlocked position before you attempt to remove a
drive. If the drives are locked, pulling on the drive to remove it could damage the
2. Wait for the lower or left LED on the front of the drive to stop blinking.
