About Slammer Fan Module Replacement
Each Slammer control unit (CU) has two fan FRUs. The following figure shows a fan FRU, which is composed of a pair of fan assemblies. This means that each CU has four fan assemblies for cooling.
Slammer fan FRU

Note: When the fan FRU status shows that the FRU has failed, either fan assembly within the FRU may have failed. It is possible that the visible assembly in front is good while the rear assembly has failed.
It is also possible that the good fan in the rear may cause the failed front fan blades to continue to rotate. The following figure shows a Slammer face with the bezel removed, identifies the location of the Slammer fans.

Slammer Fan Replacement Tasks
Step 1. Identify the Target FRU.
Step 2. Prepare Prepare the System for FRU Replacement.
Step 3. Replace Replace the fan FRU:
- Remove a Slammer Bezel.
- Remove a Slammer Fan FRU.
- Insert a Slammer Fan FRU.
- Attach a Slammer Bezel.
Step 4. Verify Status Performed as final step in fan replacement.
About Slammer Fan Module Removal
To help you identify the target control unit (CU) that has the FRU that needs to be replaced, Guided Maintenance beacons the bezel LEDs on the target CU. If you click Reverse Identify in the GUI, Guided Maintenance beacons all LEDs except for the target CU.
After you click Prepare System in the GUI, Guided Maintenance quiesces certain system components, allowing you to replace the fan module. After the system is prepared, Guided Maintenance displays a completion message and enables Next.
Important! When a fan module is stopped and removed, the internal temperature rises quickly and critical temperature alerts may begin to be issued. To avoid hightemperature buildup within the Slammer:
- Initiate Guided Maintenance only when you are able to replace the fan module immediately.
- Remove and replace the FRU within a five minute period.
- Replace one fan FRU at a time.
Important! To avoid electrical arcing when you remove the fan FRU, let it spin down before you replace it.
Remove a Slammer Fan FRU
- Within Guided Maintenance, click Next in the Prepare System page.
- When Guided Maintenance prompts you to remove the fan FRU and after the fans in the FRU have spun down, remove the two screws that secure the fan FRU to the Slammer chassis.
- Slide the fan FRU out of the chassis and set it aside.
Caution! Immediately replace the component to maintain proper airflow and cooling. Over-temperature conditions will occur if the replacement FRU is not installed into the chassis. Over-temperature conditions can damage other components.
About Slammer Fan Module Insertion
After you insert this FRU into a Slammer control unit (CU), use Guided
Maintenance to finish the procedure.
When the FRU replacement process is complete, the Pillar Axiom system reports the status of the FRU.
Important! To avoid high-temperature buildup within the Slammer:
- Make sure you replace one fan module at a time.
- When replacing multiple fan modules, make sure you complete each replacement within a five minute period.
Insert a Slammer Fan FRU
- Slide the replacement fan FRU into the Slammer chassis and push it into place firmly to engage the fan FRU with the motherboard tray.
Note: The system will automatically spin up the fan
- Tighten the two screws to secure the fan to the chassis.
- On the Guided Maintenance page, click Next.
- On the Verify page, click Verify Status.
If Guided Maintenance displays a verification failed message, click Try Again and re-seat the FRU. If the second attempt is not successful, contact the support to continue Guided Maintenance for the FRU.
Note: The length of time for the verification step to complete and the system to return a Normal status depends on the I/O load being carried bythe system. For that reason, Pillar recommends that you lighten the I/O load as much as possible before replacing the FRU.
- Review the status of the replacement FRU to confirm that it has a Normal status.
OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE: Complete guided maintenance
PARTS NOTE:
Return the parts if requested by Support/Engineering via the CPAS system. Otherwise dispose of replaced parts as normal
