DISPATCH INSTRUCTIONS

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

Time Estimate: 30 minutes

Task Complexity: 0

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: fan module failure

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

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

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.

The fan module is a Hot Swappable CRU.

Fan Module Overview: The six fan modules in the server are located at the front of the chassis. You can access them without removing the server cover. You might need to extend the server from the rack to access the fan modules. Each fan module contains a single fan that is mounted in an integrated, hot-serviceable component.

WHAT ACTIONS ARE REQUIRED:

A) Locate a Faulty Fan Module

View the following LEDs, which are lit when a fan module fault is detected:
- Fan Module (FAN) Fault LED on the front of the server.
- Fan Fault LED on or adjacent to the faulty fan module. Each fan module contains an LED. When the amber Service Required LED is lit, a fault has occurred on that fan module.

NOTE: The front and rear panel Service Action Required LEDs are also lit when the system detects a fan module fault. The system Overtemp LED might also light if a fan fault causes an increase in system operating temperature.

B) Removing a Fan Module

This procedure can be performed by customers while the server is running.

CAUTION: While the fan modules 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 fans in the rear row (fans 3, 4, or 5), you must replace it within 30 seconds to prevent overheating of the server.

CAUTION: The fan module contains hazardous moving parts. Unless the power to the server is completely shut down, replacing the fan modules is the only service permitted in the fan compartment.

1. Attach an antistatic wrist strap.

2. Extend the server to the maintenance position.

3. Identify the faulty fan module with a corresponding Service Required LED.

4. Using your thumb and forefinger, grasp the handle on the fan module and lift it out of the server.

CAUTION: When removing a fan module, do not rock it back and forth. Rocking fan modules can cause damage to the fan board connectors.

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 system is shut down and the power cords are removed.

C) Install a Fan Module

1. Unpack the replacement fan module and place it on an antistatic mat.

2. Install the replacement fan module into the server by completing the following tasks:
a. Align the fan module and slide it into the fan slot.

NOTE: Fan modules are keyed to ensure they are installed in the correct orientation.

b. Apply firm pressure to fully seat the fan module (You will hear a click when the fan is properly seated).

3. Return the server to the normal rack position.

OBTAIN CUSTOMER ACCEPTANCE

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

D) Verify Fan Module Functionality

1. Verify that the Service Required LED on the replaced fan module is not lit.

2. Verify that the Top Fan LED and the Service Required LED on the front of the server are not lit.

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. Use the Oracle ILOM "show faulty" command to verify that the fault has been cleared.
If the previous steps indicate that no faults have been detected, then the component has been replaced successfully. No further action is required.
