CAUTION: To prevent loss of work and damage to the computer or drive:
If you are inserting or removing a hard drive, shut down the operating system properly, then turn off the
computer. Do not remove a hard drive while the computer is on or in standby mode.
Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid
touching the connector. Refer to
Electrostatic Discharge Information on page 53 for more information
about preventing electrostatic damage.
Handle a drive carefully; do not drop it.
Do not use excessive force when inserting a drive.
Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields
such as monitors or speakers.
1. Prepare the computer for disassembly (Preparation for Disassembly on page 60).
2. Remove the computer access panel (
Computer Access Panel on page 64).
3. Remove the front bezel (
Front Bezel on page 65).
4. Disconnect the power (1) and data (2) cables from the back of the drive.
NOTE: The right-angle data cable must be used for this chassis model when installing hard drives
in the 3.5-inch bays to prevent cable damage from overflexing.
5. Remove the hard drive SATA cable from the top of the fan shroud.
