FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: An Oracle Server X5-4 Internal SAS Cable 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, customer should perform an orderly and graceful shutdown of applications and OS.  Then power off the server and remove the AC power cords from the system.

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

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

PCIe Slot Location and Identification:

1. Prepare the server for service.

1. Power off the server and disconnect the power cords from the power supplies.
2. Extend the server to the maintenance position in the rack.
3. Attach an anti-static wrist strap.
4. Remove the top cover.

2. Remove the P0 MR0/MR1 memory risers.

1. This gives you room to access the cables for removal.

3. Disconnect the two SAS cables from the HBA card in PCIe slot 2 and the DVD SATA cable (that branches off of the HBA SAS cables) from the motherboard.

1. If needed, you can first remove the HBA card from its PCIe slot to gain better access to the cable connectors.

4. Disconnect the two SAS HBA cables (0 and 1) from the disk backplane board.

       a. The white labeled cable is 0, and the yellow labeled cable is 1.

5. Remove the SAS HBA cables from the air divider, as follows.

1. Detach the NVMe (if installed), HBA, and ESM cables from the three cable clips on the memory riser side of the air divider.
2. Then, carefully lift the cables up and out of the cable slot [B] in the air divider that provides access to the disk backplane area.
3. There are three clips. The HBA cables are attached to the bottom clip.
4. Once the HBA cable is clear of the air divider clips, gently pry the air divider cable shield away from the power supply just enough to allow you to slide out the HBA cables.
5. The HBA cables need to be completely free of the air divider.

6.  Carefully thread the ends of HBA cables you detached from the HBA through the narrow space between the P0 heat sink and the power supply cage and up and out of the system.

1. The space between the P0 heat sink and the power supply cage is narrow;.the SAS cable connectors will only fit through one way.

7.  To install the replacement cable, carefully thread the to-HBA end of the cables through the narrow space between the P0 heat sink and the power supply cage.

8.  Reconnect the SAS HBA cables to the HBA card and the SATA cable to the motherboard. [The white labeled cable is 0, and the yellow labeled cable is 1]

1. If needed, reinstall the HBA card to PCIe slot 2 if you removed it earlier.

9.  Reroute the SAS HBA cables through the air divider to the disk backplane area.

10.  Reconnect the SAS HBA cables to their connectors on the disk backplane.

1. Any excess cable length should be in the PCIe card area to allow better air flow through the disk backplane area.

11.  Reinstall the P0 MR0/MR1 memory risers you removed earlier.

12. Return the Server to operation:

1. Replace the top cover.
2. Remove any anti-static measures that were used.
3. Return the server to it's normal operating position within the rack.
4. Re-install the AC power cords and any data cables that were removed but not yet re-attached.
5. Power on the server. Verify that the Power/OK indicator led lights steady on.

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
