FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: An Oracle Server X5-4 Fan Cage Assembly needs replacement

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

If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS.

A data backup is not a prerequisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.

a. Power off the server and disconnect the power cords from the power supplies.
b. Disconnect any cables plugged into the USB or video connectors on the front of the server.
c. Extend the server to the maintenance position in the rack.
d. Attach an anti-static wrist strap.
e. Remove the top cover.
f. Disconnect any cables plugged into the USB or video connectors on the front of the server.

2. Remove all fan modules

a. For each fan module grasp the handle on the fan module using your thumb and forefinger
b. Lift the fan module straight up and out of the chassis and set it aside on an antistatic mat.
(Caution- When removing a fan module, do not rock it back and forth. Rocking the fan module can cause damage to the fan board connectors)

3. Remove all memory risers

a. For each of the memory risers lift them straight up to remove them from the memory module socket.
b. set each memory riser aside on an antistatic mat. Attention to the removal order should be taken so that the modules can be replaced in the same locations from which they were removed.

4.Remove the fan cage

a. Loosen the three captive screws connecting the front-side memory riser guide to the motherboard.
b. Remove the two screws on each side of the outside of the chassis that hold the fan board unit in place.
c. Unplug the fan board data cable and the power cable. 
d. Remove the front memory riser guide by pulling it up and out of the chassis.
e. To remove, slide the fan board cage away from the front of the server (to clear the lip at the front of the chassis) and lift it out of the server.
f. Re-use the fan board cable and power cable from the faulty fan board unit as they will be utilized on the new fan board unit.

5. To install the fan board unit:

a. Insert the fan board unit into the chassis, moving it down and toward the front.
b. Reposition the front memory riser guide, routing the fan board and power cable through the riser guide.
c. Connect the fan board cable and power cable into the connectors and partially tighten the two screws that secure the riser guide to the chassis.
d. Tighten the three captive screws to hold the front memory riser guide in place.
e. To secure the fan board unit in place, fully tighten the two screws that secure the riser guide to the chassis.

6. Install the fan modules.

a. Install the fan modules back into the server. (The fan modules are keyed to ensure that they are installed in the correct orientation)
b. Press down on each of the fan modules and apply firm pressure to fully seat the fan modules.

7. Install the memory risers.

a. Align each memory riser with it's riser slot on the motherboard.
b. Push each memory riser module into it's associated CPU memory riser slot until the riser module locks in place.

8. Return the Server to operation

a. Replace the top cover
b. Remove any anti-static measures that were used.
c. Return the server to it's normal operating position within the rack.
d. Re-install the AC power cords and any data cables that were removed.
e. Power on server. Verify that the Power/OK indicator led lights steady on.

9. Set the system serial number if needed.

a. login to the ILOM as root and then enter the restricted shell to check the psnc values. Follow the example below to enter restricted shell and use the showpsnc command-

b. With a Fan Cage Assembly replacement the system should be able to automatically copy the psnc values from the backup1 and backup2 containers as long as they match.

c. As long as all of the psnc values match and are correct as in the above example this step is done. However if there was an issue during the replacement which caused the psnc values not to propagate automatically the system may need to be prompted to copy the data by either resetting the ILOM or scheduling a power cycle of the system by shutting down and removing the AC. If the SP reset or power cycle of the system does not synchronize the TLI data this will need to be fixed manually from service or escalation mode. These ILOM modes require a dynamic password and an Oracle Engineer for access. If Service mode is needed please contact the TSC and request assistance.

d.For Field Engineers: As long as all of the psnc values match and are correct as in the above example this step is done. However if there was an issue during the replacement which caused the psnc values not to propagate automatically then this will need to be fixed manually by using the copypsnc command from service or escalation mode. If you are unfamiliar with this process and require assistance please reference the steps for using copypsnc to fix the serial number detailed in the "How to update product serial number on systems which implement Top Level Identifier functionality (Doc ID 1280913.1)" and contact the TSC if needed.[This section is not visible to customers.]

10. Allow the system to power up and confirm that it functions properly.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot up system and verify full functionality
