Exchange the CEC enclosure control panel

Before you begin

Icon for electrostatic discharge wrist strap Use 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.

Remove the CEC enclosure control panel

Procedure

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.
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.
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 as shown in Figure 1.
- CEC enclosure rear blue identify LED 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.

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?
  - Yes, continue with the next step.
  - No, do not continue with this FRU replacement. Go to MAP4841 CEC enclosure fails to power off during service processor repair (Models 961, 98x).

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.
Disconnect the power cords 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 . The fasteners do not need to be unstrapped for this procedure.
Figure 4. Removing the power cords (Models 980, 983, 984)
Observe the CEC enclosure control panel green power button LED . 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.

Remove the front cover.
1. Ensure that you have the electrostatic discharge (ESD) wrist strap attached. If not, attach it now.
2. Remove the two shipping screws (if present) that secure the system to the rack.
3. Pull the cover away from the system. The cover has an indentation where you can hold onto it more easily.

Install the CEC enclosure control panel

Procedure

Replace the control panel.
1. If necessary, remove the new control panel from its packaging.
2. Align the control panel with the control panel slot.
3. Slide the control panel into the slot, and press on the terracotta tab to lock it in place.
Figure 8. Replacing the control panel
Replace the front cover.
1. Slide the cover onto the system.
2. Close the release latches by pushing in the direction shown in Figure 69. The cover snaps into place and has an indentation where you can hold onto it more easily.
3. Replace the shipping screws .

Attach the electrostatic discharge (ESD) wrist strap.
Reconnect the power cords to the CEC enclosure. See Figure 10.
Figure 10. Connecting the power cords
Verify that the CEC enclosure has power available. See Figure 73.
1. At the rear of the CEC enclosure, view the CEC enclosure power supply DC LEDs.
2. Are all DC (output) LEDs flashing?
  - Yes, continue with the next step.
  - No, ensure the power cords are properly connected. If no connection problem is found, contact your next level of support.
Figure 11. Location of the power supplies and LEDs (Models 980, 983, 984)
Wait up to 5 minutes for the CEC enclosure control panel power button LED to flash. See Figure 74.
Note: This ensures the CEC enclosure is in the power-off state.

Is the power button LED flashing?
- Yes, go to the next step.
- No, ensure the CEC enclosure power supplies are fully seated. The possible failing FRUs are the CEC enclosure system backplane, I2C interface card and cables, and control panel. You can also call the next level of support.
