Solution

CAP PROBLEM OVERVIEW: Internal SAS Cables replacement

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Netra Server X5-2 Training.

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 3-FRU

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

If the system is still up and functioning, customer should perform an orderly and graceful shutdown of applications and OS.  A data backup is not a prerequisite but is a wise precaution.

Replacing the internal SAS cables is a cold-service operation. You must power off the server and and remove the AC power cords from the system before you replace the SAS cables.

1. Consider your first step.

•  If you have not prepared for service, do so now. See “Preparing for Service”.
•  If you are removing the motherboard as part of another component's removal or installation procedure, go to Step 2.

2. Review this information and complete these prerequisites in this order.

• Remove the Filter on page 89
• Remove a Fan Module on page 122
  • Remove all fan modules.
• Remove the Fan Tray on page 80
• Rotate the Drive Cage to the Service Position on page 81
• Remove the Air Duct on page 83
• Replace the SAS cables on page ###

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Servicing the Motherboard Assembly:

1. Log into the ILOM check the fruid container values and sync them if needed.

1. To avoid mismatched fruid values causing a failure after a motherboard replacement the fruid data should be confirmed to have matching data in at least the Primary (DBP) and Backup2 (PDB) containers so that the motherboard will have it's container updated automatically after replacement.
   
2. After the fruid data in the Primary and Backup2 containers have been confirmed to match proceed with the following steps.

2. Prepare the server for service.

1. Power off the server and disconnect the power cords from the power supplies.
2. Remove  the server from the rack.
   1. 4-Post, 19-inch Hardmount Rack Instructions
      1. Support the weight of the server for removal.
      2. Loosen the center captive screw on the left and right rear support brackets.
      3. Remove the two screws securing each hardmount bracket at the front of the rack.
      4. Lift the server from the rack and set it aside on an antistatic mat.
   2. 2-Post, 19-inch Hardmount Rack
      1. Support the weight of the server for removal.
      2. Remove the two screws that secure each rear plate to the back of the post.
      3. Loosen the two screws that secure each rear plate to the eyelets of the side bracket.
      4. Slide each rear plate out of the eyelets and set them aside.
      5. Remove the two screws from each side bracket at the front of the posts.
      6. Lift the server from the rack and set it aside on an antistatic mat.
3. Attach an anti-static wrist strap.

3. Remove the Front Air Filter, the server Top Cover, all of the Fan Modules, the Fan Tray, rotate the Disk Device Cage.

1. On the front air filter pinch the right and left release levers inwards, pivot the air filter forward and lift it out and away from the chassis.
   
2. Fully loosen the two captive screws at the rear of the top cover.
3. Slide the top cover backward about .50 inch (13mm), lift top cover straight up and off from chassis.   
   Note: If the top cover will not slide back, you may have to loosen or remove the top two screws on both the left and right rack support backet.  These top screws cause the support backet to press against the top cover.
     
   
4. Remove the Fan Modules from the fan tray by pulling up on the green handle.
5. Unlock the Fan Tray from the system
   
6. Disconnect the cables attached to the disk backplane and the cable attached to the USB board.
   
7. Fully loosen the four captive screws securing the drive cage to the chassis (use a No. 2 Phillips screwdriver).
8. Rotate the drive cage to the vertical position.

4. Remove the air baffle.

1. Move all cables away from the top of the air baffle.
2. Fully loosen the thumbscrew on the left bracket for the air baffle.  
3. Slide the left (L) thumbscrew bracket forward and off of the mounting pins and set the thumbscrew bracket aside.
4. Lift the air duct straight up and off the alignment pins.  Set the air duct aside.

5. Replace the SAS cables

1. Disconnect the two SAS cables connected to the motherboard SAS ports, set aside the cables.
   
2. Connect the replacement SAS cables to the appropriate SAS ports on the motherboard.

8. Reinstall the main air baffle, fan tray, fan modules, rotate/secure drive cage, reconnect cables to DBP.

1. Reinstall the main air duct.
   1. Move any loose cables to the gap between the DIMMs and the chassis walls.
   2. Align the air duct to where it installs into the chassis.
   3. Lower the air duct onto the alignment pins.
   4. Set the left (L) thumbscrew bracket over the alignment pins and slide it rearward. Tighten the thumbscrew.
      
2. Reinstall the Fan Tray
   
   1. Align the fan tray to where it installs into the chassis.  Two arrows on the top of power supply bay show where the fan tray aligns.
   2. Slowly lower the fan tray into the chassis.  Verify that the fan tray is properly seated and the top surfaces of the fan tray are flush with the chassis.
   3. Close the two fan tray locks.
3. Reinstall the fan modules.
   1. Align the fan module to the location where it installs into the fan tray.  The green band is on the top of the fan module and the arrow points to the rear of the chassis.
   2. Lower the fan module into the fan tray.
   3. Press the fan module down until it clicks securely in the fan tray.
   4. Repeat steps 1 through 3 for the remaining fan modules.
4. Lower the drive cage to the horizontal position.  Tighten the four screws securing the drive cage to the chassis.
5. Connect the cables to the drive backplane, and the cable attached to the USB board.  Plug each cable into its connector until you hear an audible click.
6. Complete the routing of each cable into the appropriate cable clamps..
7. Reinstall the air filter
   1. Set the bottom edge of the filter into the lip at the front of the chassis.  The left and right release levers are facing forward.
      
   2. Pivot the filter to vertical.  The release levers snap the filter into place.
8. Install the top cover
   1. Position the top cover on the chassis, with the front edge of the top cover 0.5 in. (13 mm) rearward of the front edge of the chassis.
   2. Slide the top cover forward into place.
   3. Secure the top cover with the two captive screws at the rear.
9. Reinstall or tighten the side bracket support screws.
   

9. Return the Server to operation.

1. Remove any anti-static measures that were used.
2. Return the server to it's normal operating position within the rack.
3. Re-install the power cords and any data cables that were removed.
4. Power on server. Verify that the Power/OK indicator led lights steady on.

    12.  Check ILOM event log to see if any new errors are reported.
