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.

Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED?: No special skills required, Customer Replaceable Unit (CRU) procedure

TASK COMPLEXITY: 0

TIME ESTIMATE: 15 minutes

HOT replacement

REMOVAL/REPLACEMENT INSTRUCTIONS:

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

WHAT ACTIONS ARE REQUIRED?:

Removing a Fan Module

Caution

Do not remove more than one fan module at a time, to avoid system shutdown.
The Switch Chassis has 36 Fan Modules, each Switch unit has six dedicated fan modules
At any given time, a Switch Unit must have at least five operating fan modules.
You can only remove a fan with the server running if you have a single fan module that is faulty and if you have a replacement fan module.

1. Use one of these Oracle ILOM commands to display faulty components:

-> show faulty
-> show /System/Open_Problems
faultmgmtsp> fmadm faulty

2. Locate the faulty fan module by its amber Service Required LED

3. Use a grounding strap to protect the equipment from ESD damage

4. Unpack and prepare the replacement fan module :

If there is a protective cover on the connectors, remove the cover.
Inspect the connectors for possible damage.

5. Remove the faulty fan module from the server:

Press the green latch above the LEDs to the right to disengage the fan latch.
Grasp the metal handle on the fan module and slide the module out to remove it from the server.

Installing a fan module

1. Use a grounding strap to protect the equipment from ESD damage

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

3. Push the fan into the slot until it clicks into place, to completely seat the fan module into the slot.

4. Power on the server, if necessary.

WHAT ACTION ARE NEEDED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

1. Verify that the fault has been cleared and the replaced component is operational

2. Verify that the Power OK LED is lit, and that the Fault LED and front and rear Service Required LEDs are not lit.

3. Verify that there is no faulty components

-> show faulty
-> show /System/Open_Problems
faultmgmtsp> fmadm faulty

4. Perform one of the following tasks based on your verification results

If the previous steps did not clear the fault, refer to doc 1309092.1 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

Return the faulted component to Oracle.

If the replacement included safety covers on the connectors, install the covers on the component that you are
In the shipping container that contained the replacement component:
1. Using the same material used to pack the replacement component, position the component so that it is not free to move.
2. Add any required paperwork or other documentation in the container.
3. Except when packing CMIOUs, include any tools that were loaned to you by Oracle. Do not place tools inside a container that is being used to return a CMIOU.
Close the shipping container and seal it with the packaging tape supplied by Oracle.
Apply the shipping label to the shipping container.
Notify Oracle or an authorized shipper that the carton container is ready for pickup.
