Removing the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D system backplane

Learn how to remove the system backplane from a server to replace a failing part or as part of another service procedure.

1. Access the Advanced System Management Interface (ASMI).

   The ASMI is the interface to the service processor that is required to perform general and administrator-level service tasks, such as reading service processor error logs, reading vital product data, setting up the service processor, and controlling the system power. The ASMI might also be referred to as the service processor menus. To access the ASMI, see Accessing the Advanced System Management Interface . After you have accessed the ASMI, continue with the next step.

2. Check and record the System Enclosure Type and Feature Code.

   The enclosure serial number is a seven-digit number that is printed on a bar-coded label on the system unit.

   Note: The feature code number for the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D system backplane is 78AB-001.
3. Record the bootlist settings by using the Systems Management Services (SMS).
4. Check and record the server settings.
   Before replacing this field-replaceable unit (FRU), check and record all server settings since you might need to update the system after you replace this FRU. This can be done through the ASMI.

   1. Check and record the server firmware level that is indicated on the right edge of the status frame, the area where the Log out button is located. You might need to update the system to the latest server firmware code level after you replace this FRU.
   2. Check and record the service processor settings that you previously set using the ASMI. You will need to reset these service processor settings after you update this FRU or the default settings will be used. It is recommended you record these settings, however you may not need to reenter all of them after you replace this FRU.
   3. Record System Power Control settings:
      1. In the navigation area, select Power Restart/Control > Power On/Off settings.
      2. Manually record the values of system diagnostic level for the next boot, firmware boot side for the next boot, system operating mode, server firmware start policy, system power off policy, and default partition environment.
   4. Record System Service Aids settings:
      1. In the navigation area, select System Service Aids > System Dump.
      2. Manually record the system dump policy, hardware content, and server firmware content settings.

   5. Record System Configuration settings:
      1. In the navigation area, select System Configuration settings > System Name.
      2. Manually record the system name.
         Note: For systems ordered with feature code 2319, the Field Core Override (FCO) setting must be recorded. For more information, see Field core override function overview.
      3. In the navigation area, select System Configuration settings > Hardware Deconfiguration > Field Core Override.
      4. Manually record the current FCO setting.
   6. Record Network Services settings:
      1. In the navigation area, select Network Services settings > Network Configuration.

      2. Manually record the value for the system brand, which appears in the right pane.
      3. In the navigation area, select System Configuration > Program Vital Product Data > System Keywords.
      4. Manually record the machine type-model, system serial number, system unique ID values, reserved, and RB keyword0.
      5. In the navigation area, select System Configuration > Program Vital Product Data > System Enclosures.
   10. Record Enclosure information:
       1. In the right pane, select the Enclosure location: UXXXX.YYY.ZZZZ and click Continue.
       2. Manually record the values of enclosure location, feature code/sequence number, enclosure serial number, and reserved.
   11. Record any service processor settings that you might have set using the operating system commands.
5. Shut down the partitions and power off the system.

   This FRU cannot be serviced concurrently. Every partition must be shut down, and the system must be powered off to continue the repair. Authorization must come from the customer to shut down all running partitions and to power off the system. If the customer does not allow the partitions to be shut down or the system to be powered off, delay the service procedure. If the customer is using a secondary management console to manage the system, ensure that the customer is not powering on the system at this time.

   For instructions, see Stopping a system or logical partition.
6. Disconnect the power source from the system by unplugging the system.
   Note: This system is optionally equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected.
