Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED

No special skills required, Customer Replaceable Unit (CRU) procedure

Time Estimate: 50 minutes

Task Complexity: 0

REMOVAL/REPLACEMENT INSTRUCTIONS

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

1. Prepare for servicing:
a. Attach an antistatic wrist strap.
b. Extend the server to the maintenance position.

2. Identify the faulty fan module with a corresponding Service Required LED, located on the fan module

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 back row, you must replace it within 30 seconds to prevent overheating of the server.

WHAT ACTIONS ARE REQUIRED:

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

Legend:

Each fan module contains an LED. When the amber Service Required LED is lit, a fault has occurred on that fan module.

Remove and Install a Fan Module

For Removing-

Using your thumb and forefinger, grasp the handle on the fan module and lift it
out of the server. This procedure can be performed by customers while the server is running.

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

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.

For Installing-

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.
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.

Caution :
To ensure proper system cooling, be certain to install the replacement fan module in the same slot from which the faulty fan was removed.
Note :
Fan modules are keyed to ensure they are installed in the correct orientation.

OBTAIN CUSTOMER ACCEPTANCE

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. Run the ILOM show faulty command to verify that the fault has been cleared.
4. Perform one of the following tasks based on your verification results:
> If the previous steps indicate that no faults have been detected, then the
component has been replaced successfully. No further action is required.

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Verify functionality, no service LEDs or messages.
