DISPATCH INSTRUCTIONS

- WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED:

Product knowledge, FS1-2 Flash Storage System

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 3

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

NOTE: This Action Plan requires the following 3 items.  They come as part of the CPU FRU or can be ordered separately by the FE:

• CPU Installation/Removal Tool - part # 7026168
• Thermal Grease Kit - part # 350-1271 and contains:
• Thermal Grease Syringe - 310-0065
• Alcohol wipes - 250-1802

There is also an animation video that details the replace procedure available at the Oracle Server Animations.

PROBLEM OVERVIEW: 

FS1-2 Pilot CPU has failed or has damaged Heatsink.

What: A Pilot CPU in an FS1-2 has failed and needs to be replaced.  Heatsinks typically need replacement only when physically damaged (broken screw or bent fin) or when the CPU overheats as it is only metal and has no working parts.

Where: Failed CPUs will be a System Alert that identifies its location.  There is also the Fault Remind button on the motherboard.  Heatsink replacements can be identified by physical damage or it's associated CPU has had heat damage.

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

The Pilot with the CPU failure will have a warning status.  The other Pilot must have a normal status as this procedure may require a Pilot failover so that the problem Pilot can be powered off in order to replace the failed CPU/Heatsink.

QRC for Heatsink procedure:                                               QRC for CPU procedure:

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

1. Prepare FS1-2 for service procedure.
1. Disable Call-Home to prevent spurious alerts (see Document 1942676.1 FS System: How to Disable Call-Home to Prevent Automatic Service Request (ASR) Generation).
2. Use ESD precautions.
3. Log into Oracle FS System Manager to access Guided Maintenance:
1. Select System tab
2. In the navigation tree, expand Hardware and select Pilots
3. In the main window, right click on the Pilot with the failed CPU/Heatsink and select Repair Pilot.
4. In the pop-up Repair window, select CPU or Heatsink followed by the Next button.
5. Follow the steps in Guided Maintenance to identify and place the Pilot offline.
   
   
2. Access the CPU/Heatsink.
1. Deploy the anti-tip legs in the front of the rack.
2. Slide the Pilot into the service position.
3. Unplug both power cords.
4. Slide the Top Cover back and remove.
5. If servicing CPU 1, remove the clear plastic cover to access Heatsink screws.
   
   
3. Remove Heatsink.
1. If CPU is defective, use FAULT REMIND button to confirm CPU location otherwise confirm the broken or damaged Heatsink visually.
2. While gently pushing down on the Heatsink, loosen 4 screws 1.5 turns each using a crossing pattern until all the screws are free.
3. Gently rotate the Heatsink back and forth slightly while pulling up to free it from the CPU.
4. Use a supplied alcohol pad, clean the Heatsink bottom and CPU top.  Be VERY careful not to damage the CPU pins or socket by applying too much pressure.  Avoid spreading the thermal grease to other surfaces .
5. If only replacing the Heatsink, skip to step 6, otherwise proceed to step 5.
   
   
4. Remove failed CPU.
1. You must use a CPU Installation/Removal tool 7026168 to extract the CPU
2. Viewing from the front, disengage the right CPU Cover Retaining Levers by pushing down on them then pushing them away from the CPU.  Repeat for left lever.  Be sure to move the levers all the way back to allow better access to the CPU Cover and CPU itself.
3. Open the CPU Cover towards the right side to expose the CPU.
4. Press the round button at the top center of the tool to unlock it.  Then place it over the CPU using the green arrow to align it properly (see video above).
5. Lock the tool to the CPU by pushing the tab next to the center button on the top of the tool.  Once CPU is locked to the tool lift the tool straight up.
6. Turn tool over to expose the CPU and gently press the round button again to unlock it.
7. Grab the CPU by the sides and remove it from the tool.
   
   
5. Install replacement CPU.
1. Lock the replacement CPU into the tool by carefully placing it in the tool and then pushing the locking tab.  Be sure to align the CPU properly using the triangle on the CPU and tool (see video).
2. Turn the tool over and carefully align it with the CPU socket on the motherboard.
3. Press the center round button on top of the tool to unlock the CPU.  Do NOT press on the CPU itself.
4. Lift the CPU tool free and clear of the Pilot.
5. Lower the CPU Cover back into place.
6. Re-engage the left lever back into place and then the right lever.
   
   
6. Install Heatsink.
1. Using the syringe it comes in, apply ~0.1 ml of thermal grease in the center of the top of the CPU.  Do NOT spread it around.
2. Verify the underside of the Heatsink is clean and if not clean it with an alcohol pad.
3. Carefully position the Heatsink over the CPU by aligning the captive mounting screws to their holes in the motherboard.
4. Once the Heatsink has made contact with the thermal grease, keep any sideways movement to a minimum.
5. Using a crossing pattern, tighten each screw 0.5 turns until all four are securely fastened.
   
   
   NOTE: If the Pilot is an X5-2 version, check to see if an Oracle System Assistant (OSA) USB drive is installed internally on the Pilot motherboard.  If one is installed, proactively remove it.  While having the OSA USB drive installed does not affect day to day operations of the FS1-2, it will create problems if the Pilot needs to be re-imaged in the future
   .
   
   
7. Reassemble Pilot components.
1. If repairs were done to CPU 1, reinstall the clear plastic cover.
2. Close the Top Cover.
   
   
8. Return Pilot to FS1-2 System.
1. Plug in both power cords.
2. Return the Pilot to the rack position.
3. Return the anti-tip legs to their normal position.
4. When finished, re-enable Call-Home.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

 Confirm the System Alert associated previously is gone and the FS1-2 status is normal/green.
