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.

PROBLEM OVERVIEW: SPARC T7-4 Fan 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.

Note - The server will continue to operate at full capacity with four or more fan modules installed in the server. The server will not operate with fewer than four fan modules installed and operating. If the server is operating with four fan modules installed and one or more of those four fan modules fails, the server will power down to keep from overheating. You can perform a hot-service on a fan module only if four or more fan modules are operational.

WHAT ACTIONS ARE REQUIRED?:

Replace the Fan Module

Note - The fan module is a hot-service component that can be replaced by a Customer.

1. Locate the faulty fan module that you want to remove from the server. Check the following indicators:

Note - See rear of server for the locations of the fan modules.

    a. Fan Module LED
    b. System Service Required LEDs on the front panel and rear I/O module
    c. Server Fan Fail LED on the front panel
    d. If the fan fault causes an overtemperature condition to occur, the server Overtemp LED will turn on, and an error message will be logged and displayed on the system console.

2. Determine if you can remove a fan module with the server running or if you must shut down the server before removing a fan module.

a. If you can remove a fan module with the server running, go to Step 3.
b. If you cannot remove a fan module with the server running, remove power From the Server to power down the server before continuing.

3. Press the green button to disengage the fan module from the chassis.

4. Pull out on the fan module to remove the fan module from the server.

Caution - Make sure you have a new fan available before removing the faulty fan to prevent overheating of the server. Please replace with new fan module with in 30 seconds of the removal of the faulty fan.

5. Insert the new fan module into the empty fan module slot.

6. The fan snaps into position with an audible click.

7. Power on the server, if necessary. If you had to power off the server before removing and installing a new fan, return the server to Operation to power on the server again.

Verify the fan module functionality

1. Check the front or rear panel LEDs for the following indications:

    a. Green System OK LED – illuminated
    b. Amber System Fault LED – not illuminated
    c. Amber System Fan Fault LED – not illuminated

2. The Front Panel System Controls and LEDs and Rear I/O Module LEDs should not show any faults.

Note - If you are replacing a fan module when the server is powered down, the LEDs might stay lit until power is restored to the server and the server can determine that the fan module is functioning properly.

3. Run the ILOM show faulty command to verify that the fault has been cleared.

4. If the previous steps indicate that no faults have been detected, then the component has been replaced successfully. No further action is required.

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:
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.
