Installing a drive
1. If you are installing a parallel drive, make sure the drive is set correctly as
either a master or a slave device. Jumper the new drive the same as the drive
being replaced. Serial ATA hard disk drives do not require a master/slave
jumper.
Refer to the documentation that comes with your drive for master/slave
jumper information.
2. Install the drive into the bay as shown.
3. Secure the new drive (if necessary) with the screws that were removed.
4. If necessary, place the drive-bay cages back into the chassis.
5. Continue at "Connecting the drive" on page 54.
