Exchange the CEC enclosure SAS RAID internal adapter

Before you begin

CAUTION:

This assembly contains mechanical moving parts. Use care when you service this assembly. (C025)

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 If earthquake resistance kit parts prevent you from servicing a rack.
This procedure is also used to replace a front SAS cable. If you are replacing a front SAS cable, you will install the new cable on the adapter before replacing the adapter in the system.

Preparing the CEC enclosure to remove and replace the SAS RAID internal adapter

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.
The management console keyboard can be moved between the operating and stowed position as needed to allow service clearance above the CEC enclosure.
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).
Figure 3. Location of the power supplies and LEDs (Models 980, 983, 984)
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 that 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 by using the hook-and-loop fastener . Unstrap the fastener to allow the enclosure to be placed in the service position.
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.

If optical Ethernet connections are used, use proper cleaning procedures.

Important: The optical cable plugs (LC connectors) and ports (SFPs) must be cleaned before connecting them. Use cleaning tool 54Y4392 or IBM-approved alternative. After cleaning SFPs with the tool, use air bulb 45D2645 or IBM-approved alternative. For detailed procedures, refer to current DS8000 Info Alerts or contact your next level of support.

Figure 25. Connecting the power cords
Verify that the CEC enclosure has power available. See Figure 26
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 that the power cords are properly connected. If no connection problem is found, contact your next level of support.
  Figure 26. 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 27.

Note: This ensures that 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.
