1.3. IPMI and KVM-over-IP Products

TYAN currently creates 2 different SKUs of the AST2050 product. One is an IPMI only version which
provides full IPMI management. The other is a KVM-over-IP version which includes all the functionality
of the IPMI only version, but also with the added features of KVM-over-IP and virtual storage support.
You would need reference the specification sheet details for each TYAN motherboard in order to pick
the appropriate SKU of product that would contain the level of support necessary for your IPMI
environment.

1.4. Web based GUI

The AST2050 has an embedded web interface which provides a user-friendly Graphics User Interface
(GUI) called the Aster GUI to access all the IPMI features. All you have to do to access the Aster GUI,
is simply enter the IP address of the B
with into your web browser. It is designed to be easy to use and has an easy learning curve because it
uses a standard Internet browser. You can expect to be up and running in only minutes.

2. Using the AST2050

The AST2050 allows both local and remote access to the BMC. For local access to the AST2050
chipset users may utilize the local LPC bus through a u tility called KCSFL ASH. Users m ay also ch oose
a IPMI utility of their choice including open source tools such as IPMITool, OpenIPMI, IPMI Util or
TYAN’s UH8 IPMI utility. The UH8.exe utility is available through the TYAN website. The O

S

ystem (OS) must have an IPMI driver installed for local management through the KCS interface to
work. Most modern OS’s have an embedded IPMI driver. If your partic ular OS doesn’t have an
embedded driver, see Section 3 at the end of the manual for further details.

Remote access to the AST2050 is provided by an onboard NIC that is shared with the Intel 82574 chip
via a RMII inter face. Users are able to access the IPMI chipset through th is LAN by entering the
AST2050’s IP address into the address bar of a web browser. Follow the steps outlined in Section 2.1
Network Configuration to configure the NIC prior to use. If you are unsure about which LAN port is
dedicate to the AST2050, please reference the motherboard manual or the TYAN Support Section for
further information about the specifics for your motherboard.

2.1. Network Configuration

By default the AST2050 is set to configure its network interface through a DHCP server. The
AST2050 will try to find a DHCP server during initialization. Once a connection is made, the DHCP
server will provide the AST2050 chip with an IP address, net mask and gateway address. We
recommend assigning the AST2050 a fixed IP address according to its MAC address instead of using
DHCP so that the IPMI IP address does not change between power cycles. The MAC addresses are
printed on white stickers with barcodes near the NICs on all TYAN motherboards.

Regardless of which of the two methods used to obtain the IP address, the IP address will be d isplayed
by the IPMI chipset at the initia l POST d uring the memory count screen once the d evice has finished its
initialization process.

The AST2050 is fully IPMI 2.0 compliant so any IPMI utility may be used to do the LAN configuration.
TYAN provides an IPMI utility that may be used to do this configuration called the UH8. UH8 is the
DOS variant of the tool, UH8L works under Linux and UH8W is the Windows version of the tool. Both of
these UH8 utilities are available on the TYAN website.

This page allows the user to configure how the BMC handles IPMI alerts. Alert destinations may be set
to allow the system to send notifications when pre-programmed conditions are met. Test alerts may
also be sent from this menu to test the notification settings.

Note: When configuring the Alerts setting, please confirm that you have ENABLED Platform Event
Filter (PEF) first in the bios. On some motherboards, the BIOS will disable PEF as the default setting.

You can check it in the BIOS setup or by using UH8 to check if PEF is enabled properly.

3.4.1.1 Modify Alert

The Modify Alert page contains drop down menus and fields to configure alert types (email, SNMP
traps), event severity, destination IP/Email address, and subject etc.

Note: After finished configure Alerts setting, you also should confirm you had configure SMTP mail
server IP. Please refer to Chapter 2.4.5 for further details.

3.4.2 Mouse Mode

This configuration is contingent on the OS that is installed on the Local Host and the destination
machine you will manage. Most current Microsoft OS’s (2000, XP, 2003, Vista, 2008) and Mac OS X
use Absolute Mode. Relative mode is used by most Linux distributions (SuSE, RHEL) and older
operating systems like Windows 95/98.

3.4.3 Network

You can view and modify the network settings from this section. You can also select whether to
obtain an IP address either automatically or manually configure one.

3.4.4 SMTP

3.5 Remote Control

This tab allow s the user to perform various remote operations such as “Console Redirection”, “Power
Control” and “Other Control”.

There are various different SKU’s for your particular motherboard that include various options for IPMI
functions. If you try to use options that are not directly supported by your particular motherboard
version, you will receive various alert messages to let you know that particular feature is not supported
on your version. Here is an example where the IPMI only SKU does not allow access to the
KVM-over-IP feature. The “Java Console” will be grayed out to show that KVM over IP is not an
active feature with this version. You will also receive a pop up window that further explains that this
feature isn’t supported on your particular model.

3.5.1 Remote Console Redirection

Press the “Java Console” button to invoke the JVIEWER to start a KVM-over-IP session

3.5.1.1 Java Console - JVIEWER

Once you have started JVIEWER you wind find bar of additional options for use

1) Video - Use JViewer <Video> menu to stop/r estart/exit console redir ect session

2) Keyboard - To avoid any problems with special key combination interference, you may need to

use this drop down menu to send special Key combinations to the remote OS.

3) Mouse - Select <Mouse sync> to allow the mouse to work correctly within the JViewer remote
screen (in sync with remote OS). Press <alt-M> to release “mouse sync” and return mouse control to
local OS.

3.6.2 Pre-reserve Configuration

The BMC will verify the firmware version. If a new a firmwa re has be en found , the n a w arning me ssage
will appear to state that an uploaded image is different than the current version.

If you wish to update your firmware, one important step to consider is the Preserve Configuration
check box. Preserve Configuration means that the flash tool will keep the previous configuration (ie.
SDR, FRU, LAN configuration and etc). If the new firmware you are flashing makes changes to some
configuration (ie. sensor threshold or etc.), you should uncheck this box.

Note: If this is the first time you have used the BMC, we aware that there will be no previous
configuration and that will cause you to lose your FRU data and static IP address.

3.7 Group Control

The page allows you t o control mult iple BMC’s at the sam e time. The machi ne that you are cur rently
logged into through the AST2050 chip set w ill be named “localhost”. You can then use this screen to g et

are connected.

3.7.1 Sensors

Click “Sensors” and you will get the sensor readings of the Host that you choose

3.7.2 localhost Event Log

Click “SEL” and you will get the system event logs of the Host that you chose.

3.7.3 Add Host

Click “Add Host” button to add additional host systems.

Input BMC IP address, user name and password. The Username and password of new BMC are
shared with localhost by default. Of course, you could type the correct one if different.

Clicking the “Save” button in the ‘add host’ page will give you the following

3.7.4 Delete Host

You can use the “Del Host(s)” button to delete any host on the list.

Click the line of host(s) you want to select, click the “Select” button and you will find the “Selected”
value become “Yes”. Only once a host(s) has been selected can it be deleted.

If the BMC is malfunctioning or not responding properly, the response column will display a wait. Only
after the system has waited for 30 seconds and attempted another retry, will the display window show
fail

Section 5 IPMI OS Drivers and Open Source Software

The AST2050 is designed to operate independently of an operating system and does not require any
additional drivers or software for remote access. The web based Aster interface used for remote

access will not allow you to access the IPMI chipset from the local machine. In order to access the
IPMI chipset from the local machine a third party IPMI utility such as IPMI tool must be used. The
AST2050 firmware is fully compliant with the IPMI 2.0 specification which allows the use of standard
IPMI drivers embedded in most current operating systems

.

5.1 Windows IPMI Driver

The AST2050 chipset su pports Intel r eference drivers. They are available direct from Microsoft’s
website. You can go to http://www.intel.com/design/servers/ipmi/tools.htm

Windows Server 2003 R2 and later include an embedded IPMI driver.

for more information.

5.2 Open IPMI Driver on Linux

The AST2050 chipset also supports the Linux open IPMI driver. Use the following commands to load
the IPMI drivers:

“modprobe ipmi_devintf”
“modprobe ipmi_si”

If you use an older version of the Linux kernel, you may need to replace module “ipmi_si” with
“ipmi_kcs”

Note: The S7002 motherboard BIOS encodes IPMI Base IO address at 0xCA2 in its DMI table IPMI
entry so most OS’s embedded IPMI drivers will support the chipset without modification.

5.3 IPMITool and Other Open Source Software

The AST2050 chipset supports open source utilities such as IPMITool, OpenIPMI and IPMI Util.
To establish an IPMITool SOL session the following section of the motherboard’s BIOS must have the
following settings configured:

Advanced > Remote Access Configuration
Serial Port Number: COM 1
Serial Port Mode: 38400, 8, n, 1

6.0 FAQ’s

1. How do I use the IPMI functionality provided by the AST2050 BMC?

There is no software to install to use IPMI wi th these motherboards. It is all provided through a web
interface. Refer to the AST2050 manual for complete instructions on how to use this interface.
Simply point your web browser to the IP address of the BMC of the motherboard you want to monitor.

2: How do I find the IP address of the BMC?

The BMC will display its IP address during POST. You will need to know the IP to access the BMC
through another computer on the network. There must either be a static IP address set through UH8
or DHCP must be enabled and the NIC must be plugged into a switch for the BMC to have a valid IP.
Otherwise it will show as 000.000.000.000.

3. Can I access the BMC on the local machine?

The BMC shares a NIC port with the motherboard instead of having a dedicated NIC. The local
machine can’t use this shared NIC to communicate with the BMC. The only way for the local machine
to log into its own BMC to monitor its own temperature sensors for example is for the board to have two
Ethernet cables. The local machine will use the second NIC to communicate with the BMC through
an Ethernet switch or router to the primary NIC that is attached to the BMC.

http://www.intel.com/design/servers/ipmi/spec.htm

- BMC (Baseboard Management Controller) – The BMC is the actual chipset that is used for the IPMI
implementation. Below is a link to help further explain what BMC chipsets ar e and how they function:
http://en.wikipedia.org/wiki/Baseboard_Management_Controller

TY AN u ses various b rands/types of BMC chipsets for our SMDC and embedded IPMI solutions. Each
chipset brings with it their own unique set of capabilities that must be integrated into the ov erall IPMI
solution. Simply put, without the BMC chipset, there would be no IPMI ability.
