Preparing the 9040-MR9 system to permanently remove an adapter

To prepare the system to permanently remove an adapter from the system, complete the steps in this procedure.

1. Take appropriate precautions for avoiding electric shock and for handling static-sensitive devices. For more information, see Avoiding electric shock and Handling static-sensitive devices.
2. Review the locations of the adapter slots and the service indicators for the adapter that you want to service. The adapters are installed in the rear of the system. Figure 1 shows the locations of the adapters in a 9040-MR9 system and the locations of the light-emitting diodes (LEDs) for the adapter.

   The number of adapter slots that are available in the system depends on the number of system processors in the system. For the adapter placement information for the available slots in this system, see Adapter placement rules and slot priorities for the 9040-MR9.

   The adapter has two LEDs that indicate the status:

   • A power/activity LED (green)
   • An error and identify function LED (amber)

   The status of the LEDs are as follows:

   • (B) Indicates that the adapter is operating correctly. The green power LED (top LED) is lit solid and the amber fault LED (bottom LED) is off.
   • (C) Indicates that the adapter is not operating correctly. The green power LED (top LED) is lit solid and the amber fault LED (bottom LED) is lit solid.
   • (D) Indicates the faulty or failed adapter was selected by using the identify function. The green power LED (top LED) is lit and the amber fault LED (bottom LED) is flashing.

   Attention: If the adapter is operating correctly, then the Activity LED is ON (green) and the Error amber LED is OFF, as shown in (B). Do not attempt to remove a working adapter.

   

3. Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
4. If applicable, open the rack door at the rear of the system.
5. Physically verify that the slot you identified is where you want to remove the adapter.
   • Use the blue identify LED on the enclosure to locate the system. Ensure that the serial number of the system matches the serial number to be serviced.
   • Look for a flashing amber LED, which identifies the slot that was selected by using the identify function.
6. If you have not yet recorded the adapter slot details, record the slot number and location of each adapter that is being removed.
   Note: Adapter slots are numbered on the rear of the system.
7. Stop the system. For instructions, see Stopping a system.
8. Label and disconnect the power cords from the system unit as shown in the following figure.
   Notes:

   • This system might be equipped with two or more power supplies. If the removing and replacing procedures require the system power to be turned off, ensure that all power sources to the system are disconnected.
   • The power cord (B) is fastened to the system with a hook-and-loop fastener (A). If you are placing the system in a service position after you disconnect the power cords, ensure that you unstrap the fastener.

   Multiple power cords. The product might be equipped with multiple AC power cords or multiple DC power cables. To remove all hazardous voltages, disconnect all power cords and power cables. (L003)
9. At the rear of the system, put the cable management bracket in the service position. See the following figure.
   1. Pull out the quarter-turn fasteners (B) and turn them to disengage them while you lift the cable management bracket (A) to its raised position.
   2. Turn the quarter-turn fasteners (B) to engage and lock the bracket into position.

   

10. Label and disconnect all of the cables or transceivers that are attached to the adapter you plan to remove.
    Use a hook-and-loop fastener to hold the cables in place.
    Important: If you are disconnecting the SAS AZ cable which controls the internal disk bays, use extra care when removing cables from the adapter connectors. Gently pull the blue tab straight back from the system to release the latches that secure the SAS cable to the adapter. To prevent possible tab breakage, do not pull the blue tab to the side; instead, pull the blue tab straight back. While gently pulling the blue tab, unplug and remove the SAS cable from the adapter by pulling on the black SAS cable itself. Do not apply extra pulling force on the blue tab to remove cable.
11. Attach the electrostatic discharge (ESD) wrist strap.
    The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is completed, and if applicable, until the service access cover is replaced.

    Attention:

    • Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging your hardware.
    • When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is used 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 an ESD 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. If at any point in this service process you move away from the system, it is important to again discharge yourself by touching an unpainted metal surface for at least 5 seconds before you continue with the service process.
