SATA Backplane Replacement
Before you begin the SATA backplane removal procedure, read the following statements:
Caution: Use caution when working with the SATA/SAS backplane. Do not touch the backplane
with any metal objects, and make sure that ribbon cables do not touch the backplane. Also,
regardless of how many drives are installed, all eight drive carriers must remain in the chassis to
maintain proper airflow. Failure to follow these precautions can damage the equipment.
• Use a grounded wrist strap to prevent static discharge.
• Touch a grounded metal object before removing a component from the antistatic bag.
• Handle the RAID card by its edges only; do not touch its components, peripheral chips,
memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the card and peripherals back into their antistatic bags when not in use.
Use the following procedure to replace the SATA backplane:
1. Power down the system and remove the power cord from each power supply.
2. Access the inside of the server chassis (refer to “Access the Inside of the Chassis” on
page 23 ).
3. Remove all of the system disk drives (refer to “Disk Drive Replacement” on page 97 ).
4. Disconnect the SATA/SAS data cables from the backplane.
5. Disconnect the power supply cables and DVD-CD power cable from the backplane.
6. Remove three screws that secure the backplane to the chassis (refer to Figure 4-10 ).
7. Remove the backplane from the chassis and place it on an ESD-safe surface.
