How to remove and replace Brick Power Supply-Fan Module

A Brick has two power supply-fan modules, one on each side of the Brick. Each module provides shared power for the whole Brick and focused cooling for one of the control units (CUs). The modules are rated to power the entire Brick. The cooling fans are powered from a common bus and will be powered from the other module if the module in which they reside fails. If a module fails or is turned off:

- All fans in the Brick increase speed markedly to provide the extra cooling.

- An audible alarm, the only audible alarm on the Oracle Axiom system, is turned on.

Note: The fans in the power supply fan module are not visible and it is not possible to tell visually if the fan is spinning. Some models have curved fan supports that appear to be fan blades. In order to tell if a fan is spinning, use a moistened finger or a small strip of light weight paper.

About Brick Power Supply-Fan Module Removal

To help you identify the target Brick that has the FRU that needs to be replaced, Guided Maintenance beacons the bezel LEDs on the target Brick. If you click Reverse Identify in the GUI, Guided Maintenance beacons the LEDs on all Bricks except for the target Brick.

After you click Prepare System in the GUI, Guided Maintenance prepares the system for replacement of the power supply-fan module. After the system is prepared, Guided Maintenance displays a completion message and enables the Next button.
  
Remove a Brick Power Supply-Fan Module

Important! If you must disconnect Fiber Channel (FC) cables to make room for removal of the power supply-fan module, be careful to mark the cables so you can reconnect them in their correct locations.

1 Within Guided Maintenance, click Next in the Prepare System page.
 
2 When Guided Maintenance prompts you to power off the Brick power supply-fan module, switch off the power to the target module.

Important! Do not switch off the power to the other Brick power supply-fan module. That module supplies power to both control units (CUs).

Result: You will hear an audible alarm. The alarm is normal and indicates that the Brick is still operating but with a single power supply-fan module. The audible alarm stops when the power to the Brick is restored to full redundancy. You will also hear an increase in fan noise while all Brick fans increase in speed to provide additional cooling.

3 Slip the power-cord retaining clip up and off the power cord for the target power supply module.
 
4 Disconnect the power cord from the target power supply.
 
5 Unscrew the two screws that secure the locking tabs to the power supply module casing. The springs retain the screws in the locking tabs.
 
6 Push the power supply module's two locking tabs down.

Result: The power supply module disengages from the Brick midplane.
 
7 Slide the power supply-fan module 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.

Important! Because the power supply is also the cooling unit of the Brick, swap the module as quickly as possible.
  
About Brick Power Supply-Fan Module Insertion

After you insert this FRU into a Brick control unit (CU), use Guided Maintenance to complete the replacement procedure.

Important! If Guided Maintenance encounters a problem at this stage, you must contact theOracleWorldWideCustomerSupportCenterto continue Guided Maintenance for this FRU.

When the FRU replacement process is complete, the Oracle Axiom system reports the status of the FRU.
  
Insert a Brick Power Supply-Fan Module

1 Slide the power supply-fan module into the Brick chassis until the module stops.

2 Push up the two locking tabs on the power supply to engage the module with the Brick mid-plane.

3 Screw the two Phillips screws into the power supply module casing to secure the locking tabs.

4 Connect the power cord to the target power supply.

5 Slip the power-cord retaining clip down over the power cord for the target power supply.

6 Switch on the power to the target power supply module. As you apply power to the replacement FRU, the following should occur:

- The green LED lights.
- The audible alarm turns off.
- The fan speed may decrease.

Important! If the above actions do not occur, contact Customer Support.
 
7 In the Guided Maintenance page, click “Next”.

 

8 On the Verify page, click Verify Status.

If Guided Maintenance displays verification failed message, click Try Again and re-seat the FRU. If the second attempt is not successful, contact Customer Support to continue Guided Maintenance for the FRU.

Note: The length of time for the verification step to complete and the system to return aNormal status depends on the I/O load being carried by the system. For that reason, Oracle recommends that you lighten the I/O load as much as possible before replacing the FRU.

 

9 Review the status of the replacement FRU to confirm that it has a Normal status.
