Removing GX adapters from the 8231-E2B with the power turned off

Learn how to remove GX adapters from the 8231-E2B system with the power turned off.

1. Complete the prerequisite tasks. For instructions, see Before you begin.
   Note: Do not disconnect the power cords at this time.
2. Inspect the rear of the unit to determine if the system is using the cable management arm or if the cables have adequate length and sufficient mobility to place this unit into the service position.
3. Stop the system. For instructions, see Stopping the system or logical partition.
4. Place the system in the service position. For instructions, see Placing a 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D system in the service position.
5. Remove the service access cover. For instructions, see Removing the service access cover from the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D.
6. Identify the failing part. For instructions, see Identifying a part.
7. Identify the part to replace, by using one of the following methods:
   • Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
   • Use the service label located on the underside of the service access cover.
   Figure 1 shows the LEDs (A) associated with the GX adapters.

8. After you identify and locate the correct part and location, place the system back into the operation position. The system does not function with the cover removed; however, this position is the correct system position to disconnect the cables.
9. Disconnect and label any necessary cables with the proper connection information. The labels make it easier to reconnect the cables after you replace the adapter.
10. If applicable, remove any mechanical retaining brackets.

11. Disconnect the power source from the system by unplugging the system. For instructions, see Disconnecting the power cords.
    Note: This system is equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been disconnected.

12. Place the system in the service position. For instructions, see Placing a 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C, 8231-E2D, or 8268-E1D system in the service position.
13. 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.
14. With the system in the service position, remove the existing adapter assembly as shown in Figure 3. Unlock the latches on the adapter. Pull up the latches into the open position, and then lift the adapter out of the system.

15. If you are not replacing the adapter or installing a new adapter, place a filler panel in the slot. Seal the expansion slot by using an expansion slot cover.
