Servicing Motherboard Components |
This chapter describes how to replace the motherboard and its components in the Sun Fire X4240.
Note - Before performing any of the procedures in this chapter, perform the procedures described in Chapter 2, Preparing to Service the System. |
The following topics are covered in this chapter:
Note - Never attempt to run the server with the covers removed. Hazardous voltage is present. |
Caution - Equipment damage is possible. The covers must be in place for proper air flow. |
This section describes how to diagnose and replace faulty DDR2 (Double-Data Rate) DIMMs . The following topics are covered:
Refer to the Sun Fire X4140, X4240, and X4440 Servers Diagnostics Guide for additional DIMM troubleshooting information.
Note - CRU: This customer replaceable unit can be replaced by anyone. |
Caution - This procedure requires that you handle components that are sensitive to static discharge. This sensitivity can cause the component to fail. To avoid damage, ensure that you follow antistatic practices as described in Electrostatic Discharge Safety Measures. |
The Sun Fire X4240 Service Required LED is lit if the system detects a DDR2 DIMM fault.
To identify faulty DDR2 DIMMs:
1. Prepare the server for service.
b. Disconnect the power cord (or cords) from the power supply (or supplies).
c. Slide the server out of the rack.
See Extending the Server to the Maintenance Position.
d. Attach an antistatic wrist strap.
See Performing Electrostatic Discharge and Antistatic Prevention Measures.
2. Press and hold the Remind button to identify which DDR2 DIMM is faulty. (FIGURE 4-1)
3. Note the location of faulty DDR2 DIMMs.
Faulty DDR2 DIMMs are identified with a corresponding amber LED on the motherboard.
4. Ensure that all DDR2 DIMMs are seated correctly in their slots.
If re-seating the DDR2 DIMM does not fix the problem, remove and replace the faulty DDR2 DIMM.
Note - Refer to the Sun Fire X4140, X4240, and X4440 Servers Diagnostics Guide for more information about DIMM System Event Log (SEL) messages. |
FIGURE 4-1 Remind Button Locations
Use the DDR2 DIMM guidelines, and FIGURE 4-2 to help you plan the memory configuration of your server.
In increments of 2 DDR2 DIMMs.
Refer to the service label on the cover for DDR2 DIMM placement information. Refer to the Sun Fire X4140, X4240, and X4440 Servers Diagnostics Guide for additional DDR2 DIMM information.
The DIMM population rules for the server are as follows:
Note - DDR2 DIMM names in Integrated LOM messages are displayed with the full name, such as /SYS/MB/P0/D7. |
DDR2 DIMM fillers are installed in all unoccupied DIMM sockets. All sockets must be occupied by either a filler or a DDR2 DIMM. When DDR2 DIMMS are added, remove the fillers. When DDR2 DIMMS are removed, add extra fillers. Always place fillers in empty sockets.
FIGURE 4-3 Fillers for DDR2 DIMM Slots
If a one processor configuration is ordered, the DDR2 DIMM physical memory layout requires that all memory must be located next to the installed processor, working from the outside in. Do not install memory on the side that does not have a processor installed.
Caution - Ensure that all power is removed from the server before removing or installing DDR2 DIMMs. You must disconnect the power cables before performing this procedure. |
1. Review DDR2 DIMM Guidelines for memory configuration information.
2. Prepare the server for service.
b. Disconnect the power cord (or cords) from the power supply (or supplies).
c. Slide the server out of the rack.
See Extending the Server to the Maintenance Position.

3. Lift up the air duct. (FIGURE 4-4 [1])
4. If you are replacing a faulty DDR2 DIMM, press the Remind button on the motherboard to locate the DDR2 DIMMS that you want to replace.
The faulty DDR2 DIMM LED flashes when the Fault Remind button is pressed and held. All faulty DDR2 DIMMs are indicated with an amber LED, so that you can install the replacement DDR2 DIMM in the same location.
Tip - Make a note of the faulty DDR2 DIMM location. |
5. Push down on the ejector tabs on each side of the DDR2 DIMM until the FB-DIMM is released. [2]
6. Grasp the top corners of the faulty DDR2 DIMM and remove it from the server.

Servicetool is going to collect system information for the service processor for future part swaps. The following preconditions must be true for this to work: * The new service processor must be installed. Do you want to continue (y|n)? y Service processor FRU information ready to be collected. You MUST reboot the service processor for to complete this process. Allow the service processor to fully boot. DO NOT UNPLUG THE SYSTEM WHILE THE SERVICE PROCESSOR IS BOOTING! Would you like to reboot the service processor now (y|n)? y The system is going down NOW!! Sending SIGTERM to all processes.
1. In Escalation mode in ILOM, view product information on the FRUID PROM that is on the Power Distribution Board (PDB) by issuing this command:

Access the J1602 jumper on the rear of the motherboard next to the SATA connector , below PCIe slot 0, PCIe riser 0.
3. Place the jumper across the 2 pins of the header.
4. Remove the jumper from J1602.
5. Return the server to operation.
b. Slide the server into the the rack.
See Returning the Server to the Normal Rack Position.
c. Reconnect the power cord (or cords) to the power supply (or supplies).
Verify that the AC Present LED is lit.
If the SP (service processor) software becomes corrupted, you can reinstall the default SP software image from the Tools and Drivers CD.
This emergency flash recovery procedure returns the SP to a default configuration.
The ILOM SPBIOS <file-name>.pkg file format (for example ilom.X4150-2.0.2.6.pkg) cannot be used for emergency recovery. Use the <file-name>.bin recovery image instead.
1. Copy the following SP files from the Tools and Drivers CD, located in the recovery directory, to a USB bootable flash device.
2. Insert the bootable flash drive into the USB port.
a. Press F8 to get a list of the boot devices.
b. Choose the USB flash boot device.
a. Press F2 to enter the BIOS setup screen.
b. Choose the USB flash device as the first boot device.
3. Once the flash device is booted, run the following command:
socflash -p 1 -f <sp-binary-file>
If you want to back up the current flash content, run following command:
socflash -p 1 -f <sp-binary-file> -b <backup-binary-file>
socflash -p 1 -f g12n.bin -b ilombak.bin
Note - If you choose to back up the SP binary (-b <backup-filename>), you must ensure there is sufficient free space on the USB flash device to hold the backup file. |
Note - Use the command socflash -h to get a complete option listing. |
4. After a successful flash, perform an AC power cycle or reset the SP using the following command:
Note - Using -r (resetting the SP hardware) can cause the VGA display to become disrupted. |
Note - The BIOS is not upgraded by this emergency recovery procedure. Perform a 2nd ILOM-based flash upgrade, to update the BIOS version. |
Note - This emergency flash recovery procedure returns the SP to default configuration. |
5. Press F2 to enter system BIOS and verify that the flash device is in the boot order.
6. After a successful flash, remove the flash drive from the USB port.
Wait at least 2 minutes to let SP come up first.
8. Power on the server and enter BIOS.
9. Confirm following items are correct in BIOS:
a. BMC Firmware Revision is correct on the Main page.
b. Status of BMC is working in Advanced -> IPMI 2.0 Configuration page.
10. Exit BIOS and start the operating system.
Caution - Do not use the Reset and NMI Dump switches unless you are instructed to do so by a Field Service engineer. |
The Reset switch on the motherboard sends a reset order to the processors, resetting the main system, but not the service processor. The button for this switch is one of the 3 hidden (recessed) buttons on the back of the motherboard located between the NET MGT and NET0 connectors and closest to NET0. It can be pushed by sticking a paper clip or similar object through the hole provided on the rear of the chassis.
The NMI button is the center button of the row of 3 hidden (recessed) buttons on the back of the motherboard located between the NET MGT and NET0 connectors. The button for this switch can be pushed by sticking a paper clip or similar object through the hole provided on the rear of the chassis.
The Non-Maskable Interrupt (NMI) Dump switch sends an NMI order to the processors, which is used by Field Service for debugging activities at the request of operating system engineers. NMI can also be asserted by ILOM. Refer to the Sun Integrated Lights Out Manager User's Guide.
