ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED?: SPARC T8-4 Product Training required, to be serviced by qualified Oracle Service personnel, requires the ability to follow steps similar to what is in the Product Service manual.

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: SPARC T8-4 Front I/O (FIO) Module (Replacement

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

Note:

A data backup is not a prerequisite but is a wise precaution.
If the system is still up and functioning, the Customer should perform an orderly and graceful shutdown of the applications and operating system to get the OpenBoot PROM prompt. Run the printenv command and make a note of any OpenBoot PROM variables that have been modified.
The LDOM configuration (if any) needs to be saved before motherboard replacement to avoid loss of LDOM configuration, refer to doc 1019720.1 for details.
Then power off the server and remove the AC power cords from the system. For ALL scenarios where an AC power down or AC power cycle is required for a T8-x server, please always use the steps in doc 1571054.1 prior to physically removing AC power cables from the server.

WHAT ACTIONS ARE REQUIRED?:

Damage Alert:

Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc. If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

Replace the Front I/O (FIO) Module

This component contains the backup tli, for more information look at:

- Top Level Identifier (TLI) locations on T3-x, T4-x, T5-x, T7-x, T8-x, S7-x Systems (Doc ID 2103218.1)

and once this component has been replaced, the backup tli will be automatically overwritten by the primary tli, just capture tli information on the following way:

- -> set SESSION mode=restricted
WARNING: The "Restricted Shell" account is provided solely to allow Services to perform diagnostic tasks.
[(restricted_shell)]# showpsnc or [(restricted_shell)# showpsnc -v
[(restricted_shell)]# exit

and for more information look at:

- How to use Restricted Shell on ILOM 3.0.10 and later platforms (Doc ID 1302296.1)

1. Prepare the server for service.

a. Power off the server and disconnect the power cords from the power supplies.
b. Attach an anti-static wrist strap.

2. Remove the main module from the server and remove it's cover.

3. Locate the Front I/O (FIO) module on the main module motherboard.

4. Disconnect the ribbon cable that connects the assembly to the motherboard and remove the front I/O module assembly.

a. Pull the cable free of the connector on the main module motherboard.
b. Push the cable connector aside to access the captive screw that secures the assembly to the main module motherboard.
Loosen the screw to release the lower end of the assembly.
c. Gently pull the front I/O assembly toward the back of the main module until the ports at the front of the assembly clear the front of the main module motherboard, and then remove the front I/O assembly from the main module motherboard.

5. Insert the front I/O module assembly into position in the main module motherboard.

a. Gently slide the front I/O module assembly into position with the ports inserted into the port holes in the front of the main module motherboard.
b. Lower the rear of the front I/O module assembly so that the captive screw is aligned with the screw hole on the main module motherboard and tighten the screw.
c. Connect the assembly's ribbon cable to the connector on the main module motherboard.

6. Replace the cover on the main module and install it back into the server.

7. Return the Server to operation.

a. Remove any anti-static measures that were used.
b. Re-install the AC power cords and any data cables that were removed.
c. Power on server. Verify that the Power/OK indicator led lights steady on.

NOTE:
If a component has been replaced which contains the primary tli information and/or the tli/tag information is unknown (inconsistent/invalid), the tli/tag information needs to be re-written/re-programmed based on the available tli/tag information, if the tli/tag information is unknown the correct values can be found by using below doc:

- Find correct values of Top Level Identifier (TLI) and Servicetag on T3-x, T4-x, T5-x, T7-x, T8-x, S7-x Systems (Doc ID 2211657.1)

and advise is to contact support so that the issue can be fixed by support (via shared shell/webex/beehive or by fse/partner), for more information look at:

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FE/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot system and monitor boot sequence for errors. Test functionality of system:
1. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command to verify that the fault has been cleared.
2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear
     component faults.
   * If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
3. Restart software applications per applicable administration guides to resume system operation.
