7.3. Lift the fan tray carriage out of the chassis.

8.Remove the rear CPU module guide from the chassis.
8.1. Loosen the six captive screws that secure the guide to the motherboard and chassis.
8.2. Lift up evenly on both sides of the guide to remove it from the edge-guides in the chassis.

9.Remove the motherboard.
9.1. Disconnect the flex cable from the motherboard connector.
9.2. Disconnect the front flex indicator board flex cable connector from the motherboard connector.
9.3. Remove the six screws that secure the motherboard to the power bus bars.
9.4. Loosen the five captive screws that secure the motherboard to the chassis.
9.5. Slide the small metal door in the chassis midwall near the flex-cable connector upward to provide clearance for the power tab of the motherboard.
The metal door stays open when you slide it up into the retaining clips.
9.6. Use the motherboard lifting handle to raise the forward edge of the board until it has cleared the bus bar studs.

=====================================================
Caution - When lifting the board, avoid damaging the light pipes and connectors on the rear edge of the motherboard. 
=====================================================

9.7. Slide the board toward the front of the chassis until the connectors and light pipes are clear of the chassis back panel.
9.8. Raise the motherboard and remove it from the chassis.

10.Install the new motherboard.
10.1. Carefully lower the motherboard into the chassis with the rear of the motherboard tilted downward.
10.2. Insert the light pipes and connectors on the motherboard into the corresponding holes in the chassis back panel.
10.3. Lower the front of the motherboard, using care to align the corresponding holes in the motherboard over the six bus-bar bolts.
10.4. Lower the small metal door in the chassis midwall that closes over the motherboard power tab.
When you slide the door down, first push outward on the doorÃÂ¢ÃÂÃÂs handle to free it from the tab in the chassis midwall. This door must be closed to ensure proper air circulation and cooling.
10.5. Replace and tighten the six screws that secure the motherboard to the power bus bars. Torque screws to 7 inch-pounds (0.8 newton meters).
10.6. Tighten the five captive screws that secure the motherboard to the chassis. Torque screws to 7 inch-pounds.

11. Reconnect the flex cable to the motherboard connector.

12.Reconnect the front flex indicator board flex cable connector to the motherboard connector.

13. Replace the rear CPU module guide.
13.1. Align the edges of the guide with the metal edge-guides in the chassis, then lower the guide until it is seated firmly against the motherboard.
When you install the guide, be sure to align it so that the intrusion switch lever is over the intrusion switch on motherboard.
13.2. Tighten the six captive screws that secure the guide to the motherboard and chassis.

14. Replace the fan tray carriage to the chassis.
14.1. Carefully lower the fan tray carriage into the chassis until it is seated firmly against the motherboard and the top of the chassis.
There are two alignment pegs on the motherboard that match the holes on the fan tray carriage.
14.2. Tighten the seven captive screws that secure the fan tray carriage to the chassis and motherboard. Torque screws to 7 inch-pounds (0.8 newton-meters).
14.3. Replace and tighten the nine screws on the top surface of the fan tray carriage. Torque screws to 7 inch-pounds (0.8 newton-meters).

15. Replace all CPU modules and CPU filler boards.

=====================================================
Note - When restoring CPU modules to a 2-module, 4-module, or 6-module configuration, be sure to use the same module slots that you used before. CPU modules in these configurations must be placed according to the rules.
=====================================================

15.1. Ensure that both plastic levers on the top corners of the module are in the fully open, vertical position.

=====================================================
Caution - The pins that connect the CPU module to the motherboard are very fragile. When you install the module, be very careful to align the module with the edge-guides in the bay and to rotate both plastic levers at the top corners of the module closed simultaneously to avoid jamming the connector pins.
=====================================================

15.2. Align the module edges with the metal edge-guides in the CPU module bay.
15.3. Lower the module until it touches the motherboard connector and the opened plastic levers are in contact with the edges of the bay.
15.4. Rotate both plastic levers downward until they are flat against the top corners of the module.

16. Replace all fan trays.
16.1. Align the fan tray with the bay in the chassis.
The connector at the bottom of the fan tray should be on the left (as you face the server front) to align with the connector on the motherboard.
16.2. Lower the fan tray into the bay until it comes into contact with the connector on the motherboard.
16.3. Push down gently until the connector is fully engaged and the plastic securing buttons snap into place.

17.Replace the GRASP board.
17.1. Align the GRASP board so that its connector aligns with the motherboard connector, then push down gently to seat the GRASP board onto the front plastic standoff.
17.2. Pivot the GRASP board so that it seats into the plastic retainer that is attached to the motherboard handle.
17.3. Push the GRASP board down onto the rear plastic standoff.
17.4. Carefully press down on the rear edge of the GRASP board to seat its connector into the connector on the motherboard.

=====================================================
Note - If the GRASP board installed is not the same GRASP board previously removed, you must use the servicetool command to update FRU information about the board. 
=====================================================

18. Replace any PCI cards that you removed.
18.1. Working from the rear of the chassis, pivot the PCI card latch for the slot open to receive the new PCI card.
18.2. Insert the PCI card into the PCI card slot. Ensure that the PCI card's rear connector panel engages the tab in the chassis rear panel.
18.3. Pivot the PCI card latch closed over the rear connector panel of the PCI card until it locks.

19. Check the alignment of the locate button/LED at the rear of the chassis.
Ensure that the button protrudes from the aperture on the chassis and can be depressed and released.

The mother board can be improperly installed, so that the flexible locate button/LED at the rear of the machine is slightly misaligned and is permanently depressed when the button pushes against the chassis. Misalignment causes all fault LEDs to light and generates false ILOM SEL critical log entries in the event list.

20. Replace the main cover.

21. After you replace the motherboard, use the servicetool command to update FRU information about the motherboard.
