1 Complete the procedures to prepare the PC, and to remove the side panel. See "opening and closing the PC" on page 1. 2 Remove the front panel. See "removing the front panel" on page 2. 3 Gently lay the PC on its side. 4 If you are also removing the hard disk drive, see "removing a hard disk drive" on page 6. NOTE: You do not need to remove the hard disk drive from the bracket when installing a second hard disk drive. 5 Remove the two screws on the hard disk drive bracket (N). WARNING: Make sure the IDE cable end labeled Master is connected to the primary hard disk drive. If the IDE cable is not connected correctly, the PC will not be able to locate the hard disk drives and data may be lost. 9 Place the second hard disk drive inside the chassis, and align it with the screw holes (P) on the front of the chassis. Use four regular 6/32 x ¼-inch screws (not included) to secure the hard disk drive to the front of the PC. Tighten the screws from the front of the PC chassis into the drive. 6 Slide the bracket away from the bottom of the chassis, and then pull it up and out of the chassis (O). 7 Attach the power cable to the back of the drive. 8 Make sure you attach the connector that is marked Master on the IDE ribbon cable to the back of the primary hard disk drive. Connect the remaining part of the cable, that is marked Slave, to the second hard disk drive. 10 Connect the end of the IDE cable labeled CPU to the motherboard. upgrading and servicing guide 9
