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 T7-1 Front Right LED/USB Indicator Module Replacement

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

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.

If the system is still up and functioning, the 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.

NOTE: For ALL scenarios where an AC power down or AC power cycle is required for a T7-x server, please always use the steps in doc 1571054.1 prior to physically removing AC power cables from the server.

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. Extend the server to the maintenance position in the rack.
    c. Attach an anti-static wrist strap.

Replace the Front Right LED/USB Indicator Module (FIM)

1. Remove the fan/disk cage assembly cover and fan modules from the server.

    a. Remove the 12 screws on the top and side of the fan cover with a T6 Torx screwdriver.
    b. Open the fan door on top of the server by sliding the two green buttons to unlock it, then swing it open and lift the fan cover from the server.
    c. Remove the fan modules from the server.

2. Disconnect the cables from the disk backplane.

    a. Disconnect the two SAS cables from the storage drive backplane to the motherboard. Note the cable connections in order to ease proper reconnection of the cables.
    b. Disconnect the power cable from the storage drive backplane.
    c. If present, disconnect the two optional NVMe cables from the storage drive backplane.
    d. If the server has a DVD drive, disconnect the power and DVD data connections from the DVD.
    e. Disconnect the auxiliary signal cable from the disk drive backplane.

3. Remove the Front Right LED/USB Indicator Module (FIM).

    a. Disconnect the front left LED indicator module cable and the front right LED/USB indicator module cables from the motherboard.
    b. Slide the disk cage assembly forward, and then gently lift the disk cage assembly from the chassis and set the disk cage assembly on an anti-static mat.
    c. Remove the right LED/USB indicator module by remove the two No. 2 Phillips screws that secure the LED/USB indicator module to the server front panel. If present, remove the capping tape that secures the cable to the side of the disk cage assembly.
    d. Remove the LED/USB indicator module and cable from the server front panel.

4. Install the Replacement Front Right LED/USB Indicator Module (FIM).

    a. Unpack the replacement Front Right LED/USB Indicator Module and place it on an antistatic mat.
    b. Push the LED/USB indicator module and cable through the right LED housing on the server front panel. If necessary, use a piece of capping tape to secure the cable to the side of the disk cage assembly.
    c. Insert and tighten the two No. 2 Phillips screws to secure the LED/USB indicator module to the server front panel.
    d. Gently lift the disk cage assembly and set it into the server chassis. Slightly push the disk cage assembly into the server chassis to ensure that the disk cage screw holes are correctly aligned with the server chassis.
    e. Reconnect the left LED indicator module cable and the right LED/USB indicator module cable to the motherboard.
    f. Reconnect all cables to the disk backplane.

5. Re-install the fan modules and fan/disk cage assembly cover.

    a. Install the fan modules in the server.
    b. Place the fan/disk cage assembly cover on the chassis and using a T6 Torx screwdriver, install and tighten the twelve screws (three on each top side of the chassis, and three on each side of the chassis) to secure the disk cage assembly cover.
    c. Close the fan door.

6. 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.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FE/CUSTOMER 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.
