How to Replace a Sun Fire X4140 Motherboard.

Solution

CAP PROBLEM OVERVIEW: Replacing Motherboard

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
X4140 System Training

TASK COMPLEXITY: 3

TIME ESTIMATE: 75 minutes

FIELD ENGINEER INSTRUCTIONS

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

You must Log in as root and power down the server.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.

a. Power off the server.

b. Disconnect the power cord (or cords) from the power supply (or supplies).

c. Remove the server from the rack.

d. Extend the server into the maintenance position.

e. Attach an antistatic wrist strap.

f. Remove the top cover.

2. Remove the Motherboard

Remove the air baffle.
Remove th PCIe cards and risers.
Disconnect the power distribution board ribbon cable.
Remove the DDR2 DIMMs.
Disconnect the drive data cables.
Remove the processor heat sinks from the motherboard assembly.
Remove the 4 screws that secure the motherboard to the bus bar.
Loosen the green captive screw on the front of the motherboard, that secure the motherboard tray to the chassis.
Remove the plastic air flow bezel from between the fans and the motherboard.
Remove the processors.

Remove the CMOS battery
Lift the motherboard assembly out of the chassis.
Place the motherboard assembly on an antistatic mat.

3. Install the Motherboard and replace all removed components and cables in reverse order. If the new motherboard already has a new CMOS battery

, do not replace it with the old one.

4. Return the server to operation by replacing the top cover, returning to the normal rack position and reconnecting the power cords to power supplies.

5. Power On the Server

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot up the server. Monitor and check the messages file under usual load by the server to check

CPU temperatures are normal. Use the fmadm/fmdump to clear any previous fault affecting the old mainboard. Connect to the BUI and eventually clearly any remaning fualty component (if, of course, they belong to he mainboard unit assembly).

NOTE: SB replacement can lead to to a serial number of '00000000' which will break ASR if the SBs are not reprogrammed after replacement. In order to reprogram the serial number you will first need access into 'Service Mode' and this requires a long password which is obtained from our TSC backline. This 'Escalation' password is needed to reprogram the serial number of the system board.

An Escalation password (similar to service password) is valid for 48 hours, and is provided by our TSC backline. The following information is needed in order for the TSC backline to generate your temporary password granting access to Service Mode in order to reprogram the serial number.
You will initially need to provide the following information:
..ILOM Version? (see "version" output)
..Serial Number? (-> show /SYS [ or /CH ] product_serial_number )
..When you will be onsite? (How soon do you need this escalation password?)
Please refer to document 'x86_serial_number_10_min_1.1.2.pdf'
for additional scope on reprogramming the serial number of the system board.
