For this release, there are two new features that are described in this section.
The Alarm port is located on the rear panel and uses a standard DB-15 connector. In a telecommunications environment, the Alarm port connects to the central office alarming system. Refer to the Sun Netra X4450 Server Service Manual for alarm connector pinouts and signals.
There are two ILOM controlled watchdog timers supported on the service processor:
These watchdog timers enable the service processor to reset or power off the system if the BIOS or operating system (OS) crashes or hangs. Both watchdog timers are set using the BIOS Setup Utility.
Refer to the Sun Netra X4450 Server Service Manual for information on configuring the watchdog timers.
To determine the power consumption requirements at your site, use the following power calculator:

The Sun Netra X4450 server supports several optional PCI cards. Additional cards are being qualified, so the following table might not be complete.
The Solaris 10 10/08 OS is preinstalled on the Sun Netra X4450 server.
Before contacting support, ensure that all mandatory patches
are installed on your server. Check the SunSolve
web
site on a regular basis for the availability of new patches.
Note - If you add option cards to the server, refer to the documentation and README files for each card to determine if additional patches are required. |
Determine if the patches are installed on the server:
# showrev -p | grep “Patch: patch_number” |
where patch_number is the number of the patch that you want to install.
Go to the SunSolve site to download the patches.
Using the SunSolve PatchFinder tool, specify the base Patch ID number (the first six digits) to access the current release of a patch.
The system firmware includes Sun Integrated Lights Out Manager (ILOM) software, the Basic Input/Output System (BIOS), and POST firmware. The following are the minimum supported versions of system firmware for this release of the Sun Netra X4450 server:
Firmware updates are available from the Sun Download Center (SDLC) at:
For details on how to update your firmware, refer to the Sun Netra X4450 Server Installation Guide. Updating your system firmware updates your ILOM software and the BIOS and POST firmware.
This section describes the preinstalled and preloaded software on the server. The preinstalled software is ready to use. The preloaded software must first be installed from the preloaded location.
The following issues apply to the Sun Netra X4450 server.
This section contains issues that have been found on x86 platforms when running the Solaris OS.
When the dbx debugger is being used on the Solaris 10 5/08 for x86/x64 platforms to debug a program that raises or delivers signals that have signal handlers, dbx might receive an unexpected SIGTRAP signal from the kernel that causes it to hang. This situation can occur when dbx is single stepping, running to a breakpoint, collecting runtime checking (RTC) data, or performing any other activity that depends on signal trapping.
In some cases, dbx displays a warning of a unexpected SIGTRAP signal when it hangs:
dbx: internal warning: unexpected SIGTRAP! |
In other cases, dbx indicates receipt of a SEGV signal, as in the following example:
signal SEGV (no mapping at the fault address) in main at line 29 in file "test.c" |
If you use a cont -sig SEGV command to continue execution with the SEGV signal, dbx will display the SIGTRAP warning.
For the Sun Studio 12 debugger, sigsegv and sigaltstack are restricted on Solaris 10 Update 5 x86/x64.
RTC instruments memory access instructions for access checking. These instructions are handled by a sigsegv handler at runtime. Because RTC requires its own sigsegv handler and signal alternate stack, any attempts to install an sigsegv handler or signal alternate stack (sigaltstack) will result in EINVAL, or the installation will be ignored. The sigsegv handler calls cannot be nested. Otherwise, the nesting will result in a terminating signal 11 SIGSEGV error.
Workaround: If a terminating signal 11 SIGSEGV error occurs, use rtc skippatch to skip the instrumentation of the affected function. Otherwise, install patch 124873-06 to fix most of the segvs errors.
The system alarms are set and cleared using IPMItool commands. Refer to the Sun Integrated Lights Out Manager 2.0 Supplement for the Sun Netra X4450 Server for examples of these IPMItool commands. You can download the IPMItool utility from the following web site:
http://ipmitool.sourceforge.net/
IPMItool version 1.8.9.4 or later is required for the Sun Netra X4450 server’s service processor (ILOM version 2.0.2.6) and IPMItool version 1.8.8 or later is required to run on the host OS.
You can use the ipmitool -V command to get IPMItool version information.
A critical alarm is asserted by default when system power is not applied. The critical alarm must be reset by the user application in order to be deasserted. A critical alarm is reasserted by a subsequent power failures or by the user application. IPMItool commands can be used to set and reset the system alarms.
The following issues apply to the hardware or BIOS.
Under rare circumstances, you might see a BMC not responding message during BIOS POST. If the BIOS halts and reports this message, reboot the server by pressing Crtl+Alt+Delete. Refer to CR 6714006 for more information.
The SP/BIOS flash process includes an Update Successful message when the service processor (SP) flash completes. This message signals the end of the SP flash activity only. At this point in the process, the BIOS has not been flashed and premature termination of the process (for example, a manual reboot) will result in BIOS corruption. To avoid corrupting the BIOS review the flash sequence below:
Before writing a script to flash the BIOS/SP remotely, observe the sequence in real-time and test the script on a single system before updating all systems.
In order to enable a USB flash device during boot, you must press F2 to enter into BIOS menu, select Boot->Hard Disk Drives, and select USB flash device as the first drive.
When inserting a hard disk drive, do not extend the lever past 70 degrees. If the lever is extended past 70 degrees on insertion there is a risk that the right most tab might break off. The end result of accidentally breaking off the tab is purely cosmetic – the drive still functions properly if fully inserted.
If you need to open the bezel, you must ensure that the front of the server is hanging over the edge of a flat surface. The hinges on the bezel are designed to drop the bezel below the bottom edge of the server.
 | Caution - The hinges will break if you open the bezel while the front of the server is on a flat surface. |
The Sun Netra X4450 server does not require an additional surge protector for the AC or DC power configurations if the facility has a surge protector that limits voltage surges to less than 2000 volts. You can, however, install a surge protector if your site requires an additional protector.
The following issues are related to the Sun Integrated Lights Out Manager (ILOM) remote console system. For more information on the ILOM, see the online Sun Integrated Lights Out Manager 2.0 User’s Guide (820-1188).
For some USB flash devices, the virtual device will appear mounted in the ILOM, but will not actually be mounted. This issue is under investigation.
When you start a Remote Console session on a Solaris system, the system prompts you for a decision regarding the javaRKVM.jnlp file. You have the following two options:
If you are logged in as root, choose the option to open this file with its default application.
If you are logged in as a user other than root, perform the following procedure.
When the server prompts you, choose the option to save the file.
The javaRKVM.jnlp file is downloaded and must be run manually. The download manager displays the location of this file.
% /location_of_javaws/javaws /tmp/javaRKVM.jnlp |
This opens a Remote Console session. After the remote console window is closed, the /tmp/javaRKVM.jnlp file is removed.
When you perform remote installations, you should change the web interface time-out duration.
You must select the correct mouse mode corresponding to the host OS in order for your local mouse to manage the host remotely via the ILOM web interface.
Press Alt-M to switch control between local mouse and host mouse.
If you have a pop-up blocker enabled in the browser that is running the remote console through the ILOM web interface, the remote console will be blocked from starting on Firefox. If you do not see the remote console, check to see if the built‐in pop-up blocker has blocked it.
If you are running Solaris OS on your remote console system, you must log into the operating system as root (superuser) to mount any virtual devices.
Virtual Media is considered a USB device by the server, and is listed as a CD-ROM device. This setting overrules any CD-ROM currently set as a USB device.
Perform the following procedure if you need to enable the virtual CD-ROM during the boot process.
When installing an OS remotely using a Remote Console session, each CD request from an installation requires the user to unmount and remount the virtual CD-ROM. When a virtual CD is ejected, the OS treats it as a USB device removal. You must remount the virtual CD to continue the installation.
The ILOM browser issues are contained in this section.
TABLE 1-3 shows the minimum versions that are supported for running the ILOM web interface for the Sun Netra X4450 server on the Solaris, Linux, and Windows operating systems.
Java Runtime Environment
(JRE) 5 Update 7 is the minimum supported version for the browsers
to run the ILOM web interface.
This section contains issues in the Sun Netra X4450 server documentation that were found after the release of the documentation.
This section contains issues that were found in the Sun Netra X4450 Server Service Manual.
Appendix A in the service manual contains NIC naming values and booting priority that are incorrect.
The following table contains the correct name values.
The PCI mezzanine board (F371-3636-xx), PCI auxillary board (F371-4413-xx), and the power distribution board (F371-4369-xx) have specific jumper settings that must be followed when these components are replaced.
This section contains issues that were found in the Sun Netra X4450 Server Installation Guide.
The following cautions should have been included in the overview section.
| Caution - To maintain NEBS compliance, all I/O ports, except the Ethernet ports, must use shielded cables, and both ends of the shield must be grounded. |
