The information in this section applies to:
The following sections highlight some issues that you should take into account when performing the remove and replace procedures in this chapter.
An updated version of the Sun Fire V40z server has been released. Due to changes on the motherboard as well as in the BIOS and firmware, a number of components--such as memory VRMs and CPU VRMs--are not interchangeable between the original and updated releases.
The chassis part number (PN) is labeled on the front panel of the server, near the DVD-ROM/diskette drive assembly.
TABLE 4-1 explains the components available for each of the server releases.
If you replace a CPU, note that a minimum BIOS level is required as shown in TABLE 4-1. The CRU or FRU might not have the minimum BIOS level so check the product download site for the applicable BIOS.
If you want to install the Solaris 9 Operating System (OS) on an updated release of the Sun Fire V20z server (either chassis PN 380-1168 or PN 380-1194), you must download a Solaris OS Install-Time Update (ITU) from the web site. This ITU is required during OS installation.
If you want to install the Solaris 9 OS on an updated release of the Sun Fire V40z server, you must also download this Solaris OS ITU from the web site. This ITU is required during OS installation.
The Solaris OS ITU is available from the product web site:
http://www.sun.com/servers/entry/v40z/downloads.html
Two different versions of the Sun Fire V40z server have been released with CPUs of different stepping versions.
If you order a CPU to add or replace a CPU in your server, do not mix CPUs of different stepping versions.
![]() |
Caution - A new heat sink ships with the stepping version “E” CPU. Ensure that you do not use an old heat sink on a stepping version “E” CPU. |
Before ordering a new or replacement CPU, verify the stepping version of your CPU(s) and then order the same stepping version.
Due to the power requirements and height restrictions, the stepping version “E” CPUs work only in the Sun Fire V40z server release PN 380-1206.
In a two or four CPU configuration of the Sun Fire V40z server, all CPUs must be the same stepping version and the same speed.
You can verify the stepping version of the CPU in a local server or on a remote server.
To verify the stepping version of your CPU(s) in a local server (with keyboard, video, and mouse attached):
1. Power on or reboot your server.
A message similar to the following example appears on the screen, and the memory test begins.
This sample shows the output for a Sun Fire V40z server.
----------------- PhoenixBIOS 4.0 Release 6.0 Copyright 1985-2002 Phoenix Technologies Ltd. All Rights Reserved Production RELEASE: System BIOS Revision = V2.33.5.2 SP Interface (PRS) Revision = 12 SP - BIOS Interface Active xxxxxxxxxxxxxxxxxxxxxxxxxx xx Sun Microsystems xx xx Sun Fire V40z xx xxxxxxxxxxxxxxxxxxxxxxxxxx CPU = AMD Opteron(tm) Processor 850 4 Processors Detected, CG - CG - CG - CG 7743M System RAM Passed 1024K Cache SRAM Passed ATAPI CD-ROM: CD-224E Mouse initialized -------------------------
2. During the memory test, press the Pause key.
3. Verify the stepping version of the CPUs in the line similar to the following examples:

4. To continue with the reboot, press any key.
To verify the stepping version of your CPU(s) in a remote server:
1. Enable the Serial-Over-LAN (SOL) feature on the SP.
For more information, refer to the “Serial Over LAN” section in Chapter 4 of the Sun Fire V20z and Sun Fire V40z Servers--Server Management Guide.
2. Launch the SOL session from a SP command-line interface (CLI) to connect to the platform console remotely.
3. Type the following command:
platform set console -s sp -e -S baud rate
Where baud rate is the value that you have set in the BIOS settings; the default baud rate in the BIOS settings is 9600.
For example, if the baud rate in your BIOS settings is set to the default value, you would type:
platform set console -s sp -e -S 9600
Note - This command changes the baud-rate value for the SP so that it matches the baud rate in the BIOS settings. It does not change the baud rate in the BIOS settings. |
4. Type the following command:
5. Verify that the correct baud rate appears in the Speed column.
Using the example above, the output should appear as follows:
Rear Panel Console Redirection Speed Pruning Log Trigger SP Console Enabled 9600 No 244 KB
6. Activate the SOL session by typing the following command:
7. Create another SP session from the SP prompt.
8. Recycle the power on the platform OS by typing the following command:
Note - Before you recycle the power, ensure that the platform OS has been shut down gracefully, or that the file system has been synchronized using the sync command. |
platform set power state cycle -W -f
9. In the SP SOL session that you launched in Step 1, you now see the output of the BIOS CPU step screen.
For a sample of this output, see Step 1 in the previous procedure, Verifying the Stepping Version in a Local Server.
10. During the server’s memory self-test, terminate the remote session in order to pause the screen:
11. Verify the stepping version of the CPUs in the line similar to the following examples:
