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:
![]() |
Caution - Never attempt to run the server with the covers removed. There is hazardous voltage present. |
![]() |
Caution - Equipment damage possible. The covers must be in place for proper air flow. |
This section describes how to diagnose and replace faulty FB-DIMMs (fully buffered DIMMs). The following topics are covered:
Note - This is a customer-replaceable unit. |
![]() |
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 Section 2.7.1, Electrostatic Discharge Safety Measures. |
The system fault LED lights if the system detects an FB-DIMM fault.
2. Unplug all power cords from the rear panel.
4. Press and hold the Remind button on the memory tray to identify which FB-DIMM is faulty. (FIGURE 4-1)
FIGURE 4-1 Remind Button Locations
5. Note the location of faulty FB-DIMMs.
Faulty FB-DIMMs are identified with a corresponding amber LED on the motherboard.
6. Ensure that all FB-DIMMs are seated correctly in their slots. If re-seating the FB-DIMM does not fix the problem, remove and replace the faulty FB-DIMM.
Use the FB-DIMM guidelines, and FIGURE 4-2 to help you plan the memory configuration of your server.
Refer to the service label on the cover for FB-DIMM placement information.
Start with Branch 0 (Channels A/B), then Branch 1 (Channels C/D).
Populate by Pair (A0/B0 then C0/D0, then A1/B1,...) of identical DIMMs.
Both Channels from the same branch must contain the same number of DIMMs (populated by pairs of identical DIMMs).
FB-DIMM fillers are installed in all unoccupied DIMM sockets. All sockets must be occupied by either a filler or an FB-DIMM. When FB-DIMMS are added, remove the fillers. When FB-DIMMS are removed, add extra fillers. Always place fillers in empty sockets.

The upgrade kit part numbers are:
Note - This upgrade kit is for upgrading to a 130W processor only. A non-130W processor does not require high capacity fan modules. |
2. Update the BIOS and firmware to the latest revision.
3. Migrate to the ILOM Lights Out Manager. (Optional)
If your Sun Fire X4450 server has embedded LOM, the server must be upgraded to ILOM before it can support the Intel Xeon processor 7400 series.
Read the ELOM to ILOM Migration Users Guide. Go to http://docs.sun.com.
To access the firmware supporting ILOM, refer to the Sun Fire X4450 Server Tools and Drivers CD/DVD Version 2.0.0. To download an image go to:
http://www.sun.com/servers/x64/x4450/downloads.jsp
After transitioning to ILOM from the 2.0.0 DVD, update the BIOS and ILOM again to the latest Tools and Drivers DVD version. BIOS version 3B50 on the 2.0.0 DVD is only a transition BIOS and does not completely support the 7400 series CPU.
4. Upgrade the Intel Xeon processor.
See Section 4.9.2, Removing a CPU.
See Section 4.9.4, Installing a CPU (Replacing Heatsink).
Do not return the server to service at this time.
5. Remove and replace the server fans with the high-capacity fan modules supplied in the upgrade kit.
See Section 3.3, Servicing Fan Modules.
6. Re-install the server and test it.
See Chapter 6, Returning the Server to Operation.
7. Return the CPU, heat sink, and server fans in the provided RMA kit.
