Sun Netra X4250 Server Features
Sun Integrated Lights Out Manager
for System Management
Sun Integrated Lights Out Manager (ILOM) is system management
firmware that is installed on Sun Netra X4250 server. ILOM runs on the service
processor (SP) and automatically initializes as soon as power is
applied to your system. With ILOM, you can monitor and manage your
server system by viewing hardware configurations, monitoring system
information, managing system alerts, and more. ILOM provides a browser-based
web interface and a command-line interface, as well as an SNMP user
interface and an IPMI user interface.
Refer to the Sun Integrated Lights
Out Manager 2.0 User’s Guide (820-1188) for more information.
The ILOM documentation is posted on the Sun Netra X4250 server documentation
web site at:
Telco Dry-Contact Alarm Port
The Alarm port is located on the Sun Netra X4250 server’s rear panel and
uses a standard DB-15 connector. In a telecommunications environment,
the Alarm port connects to the central office alarming system.

Solaris Patch Information
For this initial release, the Sun Netra X4250 server supports the Solaris
10 8/07 OS with the patches listed in TABLE 1-1. The Solaris 10 8/07
OS with patches is preinstalled on the Sun Netra X4250 server.
The patches are also available at:
TABLE 1-1 Solaris 10 8/07 Operating System Patches
||FMA patch required for 127112
||Harpertown CPU support
||Multiple USB keyboard fix
Note - 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.
To determine if a patch is present, see “To Download
Patches” on page 1.
To Download Patches
whether the patches have been installed on your system.
For example, using the showrev command,
type the following for each patch number:
# showrev -p | grep "Patch: 127112"
If you see patch information listed
for the queried patch, and the dash extension (the last two digits)
matches or exceeds the required version, your system has the proper
patches already installed and no further action is required.
For example, if Patch 127112-06 or later is installed, your
system has the required version of this patch.
If you do not see patch information listed for the
queried patch, or if the dash extension precedes the required version,
go to Step 2.
For example, if no version of the 127112 patch, or a version
with an extension of ‐05 or earlier is installed, you must
download and install the new patch.
Go to http://www.sun.com/sunsolve to
download the patches.

The following issues apply to the Sun Netra X4250 server.
Solaris OS on x86 Platforms
This section contains issues that have been found on x86 platforms
when running the Solaris OS.
Unexpected SIGTRAP Signal
Causes dbx Debugger to Hang (CR
When the dbx debugger is being used on
the Solaris 10 OS on x86 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.
Workaround: Install kernel
RTC: x86: Signal SIGSEGV if
Debugger Calls grantpt (CR 6550564)
For the Sun Studio 12 debugger, sigsegv and sigaltstack are
restricted on Solaris 10 5/08 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 a sigsegv handler
or signal alternate stack (sigaltstack) will
result in EINVAL, or the installation will
be ignored. 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.
Critical Alarms Must Be Reset
When Power Is Applied
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 failure or by the user application. IPMItool commands can
be used to set and reset the system alarms. See Use IPMItool Commands to Set
or Clear Alarms.
Use IPMItool Commands to Set
or Clear Alarms
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 X4250 Server (820‐4060) for
examples of these IPMItool commands.
You can download IPMItool utility from the following web site:
IPMItool version 126.96.36.199 or later is required for the Sun Netra X4250 server’s
service processor (ILOM version 188.8.131.52). IPMItool version 1.8.8
or later is required to run on the host OS.
Type the following command to get IPMItool version information:
Hardware and BIOS Issues
The following issues apply to the Sun Netra X4250 server hardware or BIOS.
BMC Not Responding During 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 as follows:
To Reboot the Server
Scripting the SP/BIOS Flash
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:
SP begins the flash
SP completes the flash process.
CLI returns an Update Successful message.
The system reboots and the BIOS begins the flash
The BIOS flash process completes.
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.

Important Note on Inserting
a Hard Disk 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.
Important Note on Opening the
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 X4250 server should never be connected to outside
plant power sources.
The Sun Netra X4250 server does not require a surge protector
for the AC or DC power configurations. You can, however, install
a surge protector if your site requires a protector.
System Management Issues
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).

This section contains issues that were found in the Sun
Netra X4250 Server Service Manual.
DIMM Population Rules
The Sun Netra X4250 Server Service
Manual (820-4056-10) has the DIMM population rules stated
incorrectly. The correct DIMM population rules are:
There is a 2 DIMM minimum and 16 DIMM
maximum per system, regardless of the number of processors.
DIMMs must be populated in identical pairs. Any
even number of DIMMs is allowed.
DIMMs within a given pair must be identical with
respect to size, speed, and organization.
DIMM pairs are populated in the following DIMM slot
order: A0/B0, C0/D0, A1/B1, C1/D1, and so on.
DIMM capacities can be different between different
For example, a valid mixed DIMM configuration might have 4
GByte DIMMs installed in DIMM Slots A0/B0, and 2 GByte DIMMs installed
in DIMM slots C0/D0.
DIMMs should be installed with the largest capacity
DIMM pair first.
For example, four 4 GByte DIMMs and four 2 GByte DIMMS should
be installed as follows: A0/B0=4GByte DIMMs, C0/D0=4GByte DIMMs,
A1/B1=2GByte DIMMs, C1/D1=2GByte DIMMs.

Netra X4250 Server Installation Guide.
Processor Integrated Cyptographic
Acceleration Is Not Feature
The Sun Netra X4250 Server Installation
Guide (820-4055-10) incorrectly listed “Cryptography
- Processor integrated cyptographic acceleration” as a
feature of Oracle’s Sun Netra X4250 server.
Shipping Kit Contents
The Sun Netra X4250 Server Installation
Guide (820-4055-10) incorrectly listed the shipping
list contents. The correct shipping kit contents list are:
Miscellaneous hardware, cables, and connectors
Optional cable management arm with six preinstalled
cable clips and installation instructions
The following cautions should have been included in the overview
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.
Caution - The intra-building port(s) of the
equipment or subassembly is suitable for connection to intrabuilding
or unexposed wiring or cabling only. The intra-building port(s)
of the equipment or subassembly must not be
metallically connected to interfaces that connect to the OSP or
its wiring. These interfaces are designed for use as intra-building
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE,
Issue 4) and require isolation from the exposed OSP cabling. The addition
of primary protectors is not sufficient protection in order to connect
these interfaces metallically to OSP wiring.
