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 S7-2 (1 or 2 Processor) 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 - This is a hot service procedure that can be performed by Customers while the server is running.

Caution - While the fans provide some cooling redundancy, if a fan module fails, replace it as soon as possible to maintain server availability. When you remove one of the fan modules, you should replace it within 60 seconds to prevent overheating of the server.

WHAT ACTIONS ARE REQUIRED?:

Remove Fan Module

1. Prepare the server for service.

a. Extend the server to the maintenance position in the rack.
b. Attach an antistatic wrist strap to your wrist and then to a metal area on the chassis.
c. To access the fan modules, open the fan door on top of the server by sliding the two green buttons to unlock it, then swing it open.

2. Open fan door and confirm the fan module failure and it's location.

a. To open the server fan door, slide the fan door latches to the front of the server and swing the door up to the open position.
b. Confirm which fan module is to be replaced. Each fan module has a status indicator (LED). If the LED is lit amber, the fan has failed. The status LEDs are located on the chassis mid-wall adjacent to and aligned with the fan module.

Caution - When you remove one of the fan modules, you must replace it within 60 seconds to prevent overheating of the server.

3. Remove the faulty fan module.

a. Using your thumb and forefinger, grasp the fan module in the finger recesses located in the plastic between the fans.
b. Lift the fan module straight up and out of the chassis, and set it aside on an antistatic mat.

Caution - When changing fan modules, note that only the fan modules can be removed or replaced. Do not service any other components in the fan compartment unless the server is shut down and the power cords are removed.

Caution - When removing a fan module please note that the system will shutdown the server if a fan module is not reinserted within the 60 second timeout. The fans are N+1 redundant so only one of the fans modules can be failed at one time otherwise this will also shutdown the server.

Caution - When removing a fan module, do not rock it back and forth. Rocking fans can damage the fan module connectors.

Install Fan Module

1. Install the replacement Fan Module.

a. Remove the replacement fan module from its packaging and place it on an antistatic mat. This should have been done before starting the replacement procedure so the fan is ready to install when the failed fan is removed.
b. With the top cover fan assembly door open, install the replacement fan module into the server. The fan modules are keyed to ensure that they are installed in the correct orientation.
c. Press down on the fan module and apply firm pressure to fully seat the fan module.
d. Verify that the Fan status LED that aligns with the replaced fan is green and there is no amber LED on the replacement fan module. Green means the fan module is functioning correctly.
e. Close the fan door by swinging the fan door down, then press down until the two latches snap into place.
f. Verify that the Top Fan LED on the front of the server and the Service Required LEDs on the front and rear of the server are extinguished.

2. 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. Check all power and data cables to ensure that no connections were disturbed during the service.
d. Verify that the Power/OK indicator led lights steady on and that system is operating properly.

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.
