DISPATCH INSTRUCTIONS WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?:

Sun Blade 150 product training is desirable but not required

TIME ESTIMATE: 60 mins

TASK COMPLEXITY: 1

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: CPU Module Failure

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

A data backup is not a pre-requisite but is a wise precaution.
The customer should conduct an orderly software system shutdown.

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:

Removing the CPU

1. Power off the system, remove the system cover, and attach an antistatic wrist strap

Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in
antistatic bags before placing them on any surface.

2. If necessary, remove any installed PCI cards to provide space to work.

Caution – The CPU will be damaged if you replace it incorrectly. Before you
remove the CPU, look at the CPU and observe where the diagonally cut corner
(“key”) of the CPU fits onto the socket. Viewed from the front of the system chassis,
the key is at the left rear corner of CPU.

3. Disconnect the fan power connector at J-22 on the motherboard.

4. Press the tab on the front of the heatsink retaining clip.

5. Release the tab on the back of the heatsink retaining clip.

6. Gently remove the heat sink and fan from the CPU.

7. Gently remove the EMI grounding ring.
The grounding ring connects to the motherboard with four inserts or “legs”.

8. Lift the CPU locking lever to free the CPU from the socket.

Caution – Be sure that you lift the locking lever all the way back until it is vertical.
The CPU could be damaged if the lever is not fully released.

Caution – The CPU socket is permanently attached to the motherboard: do not
attempt to lift the socket off the motherboard.

9. Gently lift the CPU from the socket.
If the CPU does not lift off easily, ensure that the locking lever is fully released.

10. Place the CPU on an antistatic mat with the pins facing up.

Replacing the CPU

1. Position the CPU over the motherboard CPU socket.

Caution – The CPU will be damaged if you replace it incorrectly. Ensure that the
CPU key is correctly positioned before you attempt to press the CPU into the socket.
Viewed from the front of the system chassis, the key is at the left rear corner of CPU.
The key is the diagonal corner cut on the CPU

2. Ensure that the CPU locking lever is in the full upright position.

3. Gently place the CPU onto the socket and ensure that the pins are correctly
aligned.

4. Push the CPU locking lever down to lock the CPU in place.

Caution – The grounding ring is precisely formed to fit the CPU. If you bend the
grounding ring, it may not properly ground the EMI. Additionally, a bent grounding
ring can interfere with CPU cooling. Be sure to position the grounding ring correctly.

5. Gently place the EMI grounding ring over the CPU.
Ensure that the grounding ring seats correctly on the CPU.

6. Gently press the grounding ring legs into the motherboard

7. Place the heatsink and fan assembly over the CPU and grounding ring.

8. Attach the heatsink retaining clip:

a. Press the back of the heatsink retaining clip over the plastic tabs on the back of
the CPU socket.

b. Press front of the clip over the front plastic tab on the CPU socket.

9. Reconnect the fan power connector at J-22 on the motherboard.

Note – Read the documentation that is provided with the new CPU to determine
the correct jumper settings.

10. Verify that the motherboard CPU mode detect jumper, JP3, is set correctly.

Note – A jumper switch is closed (sometimes referred to as shorted) with the plastic
cap inserted over two pins of the jumper. A jumper is open with the plastic cap
inserted over one, or none of the jumper pins.

Caution – Be sure that you set the jumpers correctly before powering-on the
system. A 550 MHz CPU can not operate if the jumpers are set for 650 MHz. A 650
MHz CPU will operate at 550 MHz if the jumpers are set for 550 MHz.

NOTE: Please refer to the Sun Blade 150 Service Manual (816-4379-10) for further details.

11. If you removed any PCI cards, replace them.

12. Detach the wrist strap, replace the system cover, and power on the system.

OBTAIN CUSTOMER ACCEPTANCE WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO
RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Restart software applications per applicable administration guides to resume system operation.
