6. Check the hard disk drive status indicators to verify that the hard disk drives are
operating properly. (See “Server controls and indicators” on page 6 for the
location of the status indicators.)
• When the green light flashes rapidly (three flashes per second), the controller
is identifying the drive.
Replacing a hard disk drive is done in the same manner as installing a new hard disk
drive.
If the server has a Redundant Array of Independent Disks (ServeRAID) adapter
installed, you can hot-swap drives. For more information about hot-swapping drives
refer to the documentation provided with the ServeRAID adapter, “Hot-swap disk
drives”, and to the notes under “Hard disk drives” on page 48.
Hot-swap disk drives
Your server can be configured with hardware to let you continue to operate your
system while removing or installing hard disk drives (or hot-swapping). To do this
you need a ServeRAID adapter, hard disk drive, and the hard disk drive tray.
• Each hard disk drive that you plan to install must have an accompanying hard
disk drive tray.
• The drive must be a low-voltage differential drive (LVD), and have a single
connector attached (SCA) connector.
• The hard disk drive bays connect to a SCSI backplane. This backplane is the
printed circuit board behind the bay and is connected to the ServeRAID adapter.
• The backplane controls the SCSI IDs for the hard disk drives.
Preinstallation steps
Before you install a hard disk drive, review the following.
• Inspect the drive tray for any signs of damage.
• Ensure that the drive is installed properly in the tray.
• To maintain proper system cooling, do not operate the server for more than two
minutes without either a drive or a filler panel installed in each bay.
• If your server has a ServeRAID adapter installed; refer to the documentation
provided with the ServeRAID adapter for information about adding a drive.
• Read the safety precautions listed in “Safety information” on page 107, “Handling
electrostatic discharge-sensitive devices” on page 110.
• Check the instructions that come with the drive to see if you need to set any
switches or jumpers on the drive.
