Notes:
a. After installing the hard disk drive, check the disk drive status LEDs to verify
that the hard disk drive is operating correctly.
If the amber hard disk drive status LED is lit continuously, that drive is faulty
and must be replaced. If the green hard disk drive activity LED is flashing,
the drive is being accessed.
b. If the server is configured for RAID operation using an optional ServeRAID
adapter, you might have to reconfigure your disk arrays after you install hard
disk drives. See the documentation that was included with the optional
adapter for additional information about RAID operation.
6. Close the bezel (see “Closing the bezel” on page 151).
