FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: System Board failure

OBTAIN CUSTOMER ACCEPTANCE

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/CUSTOMER ADMINISTRATOR NEED TO TAKE:

Caution – This procedure must be performed by a qualified service-trained maintenance provider. Persons who remove any of the outer panels to access this equipment must observe all safety precautions and comply with skill level requirements, certification, and all applicable local and national laws.

Replacing the System Board

1. Disconnect any external cables attached to the rear panel of the system.Be sure to note where each cable attaches to the rear panel.

2. Disconnect the internal cables from the main logic board.
Press the tab on the cable connector to detach each cable.
a. Disconnect the two power cables at connectors J2902 and J2903.
b. Disconnect the two power sense cables at connectors J2901 and J4501.
c. Disconnect the SCSI backplane data cable at connector J1801

3. Loosen the three captive screws securing the main logic board to the rear panel.

Note – Be sure to remove the SSP paddle card and all PCI cards prior to removing the main logic board.

4. Slide the main logic board away from the rear panel until it is free.

5. Pull the bottom edge of the main logic board away from the machine, and lift the board out of the system.
Place the main logic board on an antistatic mat.

Installing the New System Board

You must remove all removable components from the old main logic board so that you can transfer them to the replacement board.

Note – Be sure to remove the NVRAM/TOD module from the old main logic board so that you can transfer it to the replacement board.

1. Remove the main logic board from its antistatic packaging and place it on an antistatic mat.
Retain the packaging and use it to pack and return the defective board.

2. Set the jumpers on the replacement main logic board so that they are the same as the settings on the old board.
See “About the Main Logic Board Jumpers” on page 62 in Sun Enterprise 250 Server Owner's Guide for more information about jumper locations and settings.

3. Position the board inside the chassis.Align the notches at the top and bottom edges of the board with the corresponding
tabs on the chassis wall.

4. Press the main logic board against the chassis wall as you slide it toward the rear panel.

5. Tighten the three captive screws securing the main logic board to the rear panel.

6. Reconnect the internal cables to the main logic board:
a. Reconnect the two power cables to connectors J2902 and J2903.
b. Reconnect the two power sense cables to connectors J2901 and J4501.
c. Reconnect the SCSI backplane data cable to connector J1801.
7. Reconnect any external cables to the rear panel of the system.

Note – When the side access panel is removed, the system power interlock switches are activated. This safety mechanism prevents any DC voltages (except 5V standby power) from reaching the main logic board while the side access panel is removed. 

8. Remove the NVRAM module from the replacement board and install it on the old board for return to Oracle.

9. Complete the installation to transfer the components that you removed from the old main logic board to the new board.

10. When you are ready to restart the system, be sure to run POST and OpenBoot Diagnostic tests to verify that the system functions correctly with the new parts you have just installed.

Note – After installing the new main logic board, you must restore Remote System Control (RSC) configuration parameters before you can use RSC. During RSC configuration, RSC parameters are typically backed up to a hard disk drive. You must restore those parameters to the RSC SEEPROM on the new main logic board.

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.
