Replacing the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D disk drive backplane

Use this procedure to replace the disk drive backplane.

1. Identify the system that you will be working on by using the identify the system process to turn on the system locate (blue) indicator. For instructions, see Enabling enclosure indicators and Control panel LEDs.
2. Complete the prerequisite tasks. For instructions, see Before you begin.
3. Stop the system. For instructions, see Stopping a system or logical partition.
4. Place the system into the service position. For instructions, see Placing a rack-mounted model into the service position.
5. Disconnect the power source from the system by unplugging the system. For instructions, see Disconnecting the power cords.
   Note: This system may be equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected.

6. Remove the service access cover. For instructions, see Removing the service access cover from a rack-mounted model.
7. Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
8. Attach the wrist strap.
   Attention:

   • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
   • When using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have a wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
9. Install the control panel and signal cable. For instructions, see Control panel and signal cables.
10. Check for a protective cover that might be present on the lower-right connector pins. If a protective cover is present, remove the cover.
11. Carefully lift the backplane along two sides and align it with the slot in the server.
12. Insert the backplane firmly into the server.
    Note: Ensure that the signal cables do not bind when you install the disk drive backplane.
13. Secure the backplane into the system by pressing in the locking tabs (A), as shown in the following figures.

14. Replace the disk drives, if you removed them earlier. Use the location information that you recorded while removing the disk drives to install them the correct locations. To replace the disk drives, complete the following steps:
    1. Hold the disk drive by the top and bottom edges as you position the drive, and insert it into the system or expansion unit. Do not hold the disk drive by the handle.
    2. Slide the disk drive all the way into the system or expansion unit, and push the disk drive handle (A) in until it locks, as shown in the following figure.

15. Replace the Slimline media device by completing the following steps:
    1. Align the bracket with the tab (A) along the side of the media device. This bracket is not attached with screws, clips, or other fastening devices. It is held in place by tabs and friction.
    2. Align the small tabs in the slots of the media device (B), and insert the device and clip at the same time. Then, push the tab (A) in until it locks into place. See figure 4 or 5 based on the configuration of your system.

    For more information about replacing the different types of media devices, see Removing and replacing media devices in the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D.

16. Replace the service access cover. For instructions, see Installing the service access cover on a rack-mounted 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D system.
17. Place the system in the operating position. For instructions, see Placing the rack-mounted 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D system into the operating position.
18. Connect the power cords to the system. For instructions, see Connecting the power cords.
19. Start the system or logical partition. For instructions, see Starting the system or logical partition.
20. Verify the installed part.
    • If you replaced the part because of a failure, verify the installed part as described in Verifying a repair.
    • If you installed the part for any other reason, verify the installed part as described in Verifying the installed part.
