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.

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: SPARC T8-1 SCC PROM Replacement

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

Note:

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

Note:

The system ID PROM, sometimes referred to as the SCC, provides the server module with the host ID, MAC addresses, and some Oracle ILOM configuration information.
The system ID PROM does not typically require replacement. However, if you replace the ID PROM, be aware that the host ID and MAC address will change.

Replace the SCC PROM

1. Prepare the server for service.

a. Power off the server and disconnect the power cords from the power supplies.
b. Extend the server to the maintenance position in the rack.
c. Attach an anti-static wrist strap.

2. Remove the Top Cover of system.

3. Open the clear plastic air duct assembly cover by lifting the edge of the cover closest to the rear of the server. The cover can stand in its upright position but perform the next steps if you need to remove the cover:

a. Open the fan cover.
b. Pull open the plastic tabs to release the clear plastic air duct assembly covers hinged edge and remove it from the server.

4. Pull up on the SCC PROM to remove it from its socket.

Note:

The System Configuration PROM is plugged into a socket on the motherboard. It includes a yellow barcode label.

5. Align the SCC PROM with the socket on the motherboard.

Note:

The notch on the underside of the System Configuration PROM faces the rear of the server.

6. Plug the SCC PROM into the socket.

Note:

Gently press down on the center of the System Configuration PROM to ensure that it is fully seated.

7. Close the clear plastic air duct assembly cover by rotating it down over the motherboard / two memory risers and then slightly pressing in the two tabs to secure it. See following if you need to reattach the cover:

a. Open the fan cover.
    b. Align the clear plastic air duct assembly cover on its hinge edge.
    c. Attach the hinged plastic tabs to the server by pulling them open and letting them seat into the holes so that the clear plastic air duct assembly cover can hinge up and down.
    d. Lower the clear plastic air duct assembly cover (making sure the two pairs of side tabs clear the sides of the server).

8. Install the top cover on the system.

9. Return the Server to operation.

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

Note:

As the system boots up, watch for the banner display in the console output.

How to verify the SCC PROM is working properly

1. The Ethernet address and Host ID values are read from the SCC PROM. Their presence in the banner verifies that the SP and the host can read the SCC PROM:

SPARC T8-1, No Keyboard
Copyright (c) 1998, 2015, Oracle and/or its affiliates. All rights reserved.
OpenBoot 4.37.3.build_24, 478.2500 GB memory available, Serial #108033262.
Ethernet address 0:10:e0:70:74:ee, Host ID: 867074ee.

2. For additional verification, run specific commands to display data stored in the System Configuration PROM.

a. Use the Oracle ILOM show command to display the MAC address:

-> show /HOST macaddress

/HOST
Properties:
macaddress = 00:10:e0:70:74:ee

b. Use Oracle Solaris OS commands to display the hostid and Ethernet address:

root@T8-1-bur09-a:~# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
net0: flags=100001000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,PHYSRUNNING> mtu 1500 index 3
        inet 10.152.224.104 netmask fffffc00 broadcast 10.152.227.255
        ether 0:10:e0:70:74:ee

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot system and monitor boot sequence for errors. Test functionality of system:

Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command to verify that the fault has been cleared.
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
Restart software applications per applicable administration guides to resume system operation.
