FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: System Board Failure

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

The customer should conduct an orderly software system shutdown. Then power down the system and disconnect the Power Cord. Then Position the System for Service, Remove the System Cover, Avoid Electrostatic Discharge and Remove the Removable Media Assembly (RMA).

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1) Remove a System Board

1. Disconnect all internal cables from the main logic board:

a. Disconnect the removable media SCSI cable, at connector J4701; press the tabs on both sides of the connector to release the cable.

b. Disconnect the upper blower power cable at connector J4705.

c. Disconnect the 4-slot UltraSCSI data cable, at connector J5601; press the tabs on both sides of the connector to release the cable.

2. If one or more 8-slot UltraSCSI data cables are installed, disconnect them from their UltraSCSI controller cards and lay the cables across the top of the chassis. This will keep them out of the way when you remove the main logic board.

3. Loosen the five large captive screws that secure the main logic board to the rear of the chassis.

4. Remove the main logic board. Carefully slide the board all the way out of the chassis, using the handles at the rear of the board.

Caution - If you have not removed all CPU modules, take care that the CPU ejection levers do not catch on the chassis.

5. Place the main logic board on an antistatic mat.

2) Install a System Board

1. If you have one or more PCI cards to transfer to the replacement board, remove each corresponding PCI filler panel from the replacement board. Each empty PCI slot has a protective metal filler panel that keeps dust and stray objects from entering the server chassis. After you remove the panels, the PCI section of the replacement board and the defective board should look the same.

a. Remove the Phillips screw that secures the filler panel to the replacement board.

b. Remove the PCI filler panel. Keep the filler panel and screw for possible future use.

2. Set the jumpers on the replacement main logic board so that they are the same as
the settings on the old board.

3. Carefully push the main logic board into the chassis. The connector should insert completely at the bottom right of the board. Caution - If you have not removed CPU modules, take care that the CPU ejection levers do not catch on the chassis.

4. Tighten the five large captive screws at the rear of the chassis.

5. Connect all internal cables to the main logic board:

a. The removable media SCSI cable, at connector J4701

b. The upper blower power cable, at connector J4705

c. The 4-slot UltraSCSI data cable, at connector J5601

6. If you disconnected 8-slot UltraSCSI data cables from their UltraSCSI controller cards, reconnect them.

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Restart software applications per applicable administration guides to resume system operation.
