Exchange the CEC enclosure I2C interface card assembly

Before you begin

Icon for electrostatic discharge wrist strapUse approved ESD procedures to prevent damage.

Attention:
  • This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
  • If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
  • If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.
Notes:
  • All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
  • If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

Preparing the CEC enclosure to remove and replace the I2C interface card assembly

About this task

Procedure

  1. Use a replacement part with a valid DS8000® part number to ensure it has the proper firmware, VPD, and/or configuration to ensure it is compatible with the DS8000 service procedures. Attempting to use a generic server FRU might fail and require next level of support to recover.
  2. All parts being removed must be marked or identified so they can be installed into their original locations.
    Note: Failure to do this can extend the service duration and may require next level of support assistance.
  3. The management console keyboard can be moved between the operating and stowed position as needed to allow service clearance above the CEC enclosure.
  4. Use the front and rear blue identify LEDs to determine the CEC enclosure to be repaired. Both blue LEDs should be lit.
    • CEC control panel blue identify LED Callout label B as shown in Figure 1.
    • CEC enclosure rear blue identify LED Callout label 1 as shown in Figure 2.
    Note: If both the front and rear CEC enclosure identify LEDs are not lit, use the location code listed in the serviceable event FRU list. See MAP1245 Finding FRUs by using location codes.

  5. Verify that the CEC enclosure is in the power-off state. See Figure 3
    1. At the rear of the CEC enclosure, view all CEC enclosure power supply DC LEDs.
    2. Are all DC (output) LEDs flashing?
    Figure 3. Location of the power supplies and LEDs (Models 980, 983, 984)
    Location of the power supplies and LEDs (Model 980)
  6. Use the flashing slot identify LED to confirm the location of the adapter to be replaced.
  7. Attach the electrostatic discharge (ESD) wrist strap.
    Attention:
    • Attach an electrostatic discharge (ESD) wrist strap to an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging your hardware.
    • When using 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.
  8. Disconnect the power cords Callout label B from the CEC with the DC (output) LEDs flashing. See Figure 4.
    Notes:
    • Ensure the power cords are correctly labeled.
    • The power supply LEDs might continue to flash for up to 20 seconds while internal power is discharged.
    • The power cord is fastened to the system using the hook-and-loop fastener Callout label A. Unstrap the fastener to allow the enclosure to be placed in the service position.
    Figure 4. Removing the power cords (Models 980, 983, 984)
    Removing the power cords (Model 980)
  9. Observe the CEC enclosure control panel green power button LED Callout label A. See Figure 5.
    • If it is off, go to the next step.
    • If it is flashing, the CEC enclosure is still in the power-off state. DO NOT CONTINUE. Ensure that you have unplugged the power cables.

  14. Attach the electrostatic discharge (ESD) wrist strap. Your system has an ESD pin on the backplane as shown in Figure 11. Attach the ESD wrist strap to the ESD pin.
    Attention:
    • Attach an electrostatic discharge (ESD) wrist strap to an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging your hardware.
    • When using 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.
