Using the ASM interconnect network
This section explains how to configure and connect the server to function within an
ASM interconnect network.
The ASM interconnect network can include as many as 12 individual ASM
connections in a single bus. These connections can include Remote Supervisor
Adapters, ASM processors, and ASM PCI adapters. When the clients and servers
are connected, they use the ASM interconnect network to share ASM resources,
information, and alerts among multiple servers without having to add additional
communications hardware or network interface adapters.
ASM interconnect network provides two levels of functionality. First, the ASM
interconnect network enables you to configure settings and to control the servers
where other Remote Supervisor Adapters, ASM processors, and ASM PCI adapters
the network reside. Second, the ASM interconnect network enables other
interconnect network devices to use the resources (Ethernet or modem) of other
Remote Supervisor Adapters, ASM processors, and ASM PCI adapters in the ASM
interconnect network for sending alerts. This interconnect network is used when
Remote Supervisor Adapters, ASM processors, or ASM PCI adapters cannot send
alert and must forward the information to another one of these devices to send
the alert.
Planning and cabling the interconnect network
support the most recent ASM features, a Remote Supervisor Adapter must be
the main gateway interconnect to the ASM interconnect bus if the bus also includes
servers with ASM PCI adapters or ASM processors. The Remote Supervisor
Adapter forwards the ASM information generated by the servers attached to the
ASM interconnect bus to other servers on the Ethernet network. The connected
ASM processors and ASM PCI adapters are managed through the new user
interface and Web browser access of the Remote Supervisor Adapter.
Note: To ensure the stability of the system, you must have the most current level of
firmware installed on the Remote Supervisor Adapter that is the main
interconnect gateway for the ASM interconnect network. The most current
level of firmware is available at http://www.ibm.com/pc/support/ on the World
Wide Web. For more information about updating firmware, see “Updating the
firmware” on page 39 and the Remote Supervisor Adapter User’s Guide on
the IBM xSeries Documentation CD.
You must connect an ASM Interconnect module to the Remote Supervisor Adapter
and to each xSeries 450 server that you connect to the ASM interconnect network
bus.
Attention: To avoid damage to the Ethernet connector on the Remote Supervisor
Adapter, do not plug the ASM Interconnect module into the Remote Supervisor
Adapter Ethernet connector.
connect the servers, note the following setup and configuration considerations:
Ensure that the ASM interconnect network is set up as a bus topology. You must
connect the servers to the ASM interconnect network in a series, with terminated
beginning and end points.
Ensure that the total combined length of all Ethernet cables connecting the
server in the ASM interconnect network does not exceed 91 m (300 ft).
Each Remote Supervisor Adapter, ASM PCI adapter, or ASM processor that is
connected to the ASM interconnect network bus counts as one connection. For
IBM xSeries 450 Type 8688: Hardware Maintenance Manual and Troubleshooting Guide
If
If
example, if an ASM PCI adapter is installed in a server that has an ASM
processor, the processor and the adapter connect to each other using one ASM
interconnect connection, but the processor and the adapter count as two
connections on the ASM interconnect network bus.
Forwarding alerts
Remote Supervisor Adapters, ASM PCI adapters, and ASM processors that are
connected to an ASM interconnect network share resources and
system-management information. This section provides information on how alerts
are forwarded in the ASM interconnect network.
During normal operation, each Remote Supervisor Adapter, ASM processor, or ASM
PCI adapter on the ASM interconnect network communicates with the other
processors and adapters on the network. Processors or adapters that have a
modem or Ethernet connection notify the other processors and adapters that these
communications resources are available for use by other servers on the ASM
interconnect network. These resources are then used as ASM interconnect network
resources, enabling Remote Supervisor Adapters, ASM processors, or ASM PCI
adapters on the ASM interconnect network to send alerts using a modem or the
network, even if they do not have a modem or network connection physically
attached.
When alerts are generated, they are forwarded to the Remote Supervisor Adapter,
ASM processor, or ASM PCI adapter on the ASM interconnect network that has the
communication resources to forward the alert. If no system on the ASM interconnect
network meets the requirements, the alert is set for transmission if the connection
type is configured or becomes available later.
multiple modems or network connections exist in the ASM interconnect network,
you cannot specify which system will receive an alert or which will use its modem or
network connection to forward the alert. If an alert is forwarded to a Remote
Supervisor Adapter, ASM processor, or ASM PCI adapter that is unable to deliver
the alert (for example, the modem it is configured to use has failed or the network
cannot resolve the destination IP address), the processor or adapter attempts to
forward the alert to another system on the ASM interconnect network that has the
communication resources to forward the alert.
Alerts are typically sent once per connection type, but an alert is forwarded to
another interconnect device if the resources exist on other interconnect devices in
the network. For example, on a three ASM processor network where ASM
processor 1 generates a modem alert, but does not have a modem and the other
ASM processors have modems, the following might occur:
ASM processor 1 generates an alert and the modem is unplugged from ASM
processor 2 45 seconds prior to ASM processor 1 generating the alert, ASM
processor 1 forwards the alert to ASM processor 2, having previously determined
that ASM processor 2 has an available modem. When ASM processor 2 receives
the forwarded alert, it determines that a modem is attached to ASM processor 3
and forwards the alert. Therefore, depending on the time frame (45 seconds) within
which a resource (modem) fails, the alert might be forwarded multiple times until an
interconnect device can send the alert.
Connecting the ASM Interconnect module to the xSeries 450
The ASM Interconnect module connects the Remote Supervisor Adapter to the ASM
interconnect network. This module must be purchased separately.

Configuring the Gigabit Ethernet controller
The Ethernet controllers are integrated on the I/O board. They provide an interface
for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provide full-duplex
(FDX) capability, which enables simultaneous transmission and reception of data on
the network. If the Ethernet ports in your server support auto-negotiation, the
controllers detect the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T)
and duplex mode (full-duplex or half-duplex) of the network and automatically
operate at that rate and mode.
You do not need to set any jumpers or configure the controllers. However, you must
install a device driver to enable the operating system to address the controllers. For
device drivers and information about configuring the Ethernet controllers, see the
Resource CD that comes with your server. For updated information about
configuring the controllers, go to http://www.ibm.com/pc/support/ on the World Wide
Web.

POST error codes and messages
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of
tests is called the power-on self-test, or POST.
Notes:
This server does not produce beep codes.
Depending on system configuration, POST might run for several minutes before
the video console is enabled. During this time, POST operation is indicated by
the flashing blue locator LED on the front panel. Diagnostic display error codes
track the startup progress until video is enabled.
POST finishes without detecting any problems, the EFI Boot Manager screen
If
appears. If POST detects a problem, an error message will be sent to either the
serial port or the display screen. See “SAL/EFI messages” on page 150 for more
information.

“Error-log viewer” on page 42.
Light Path Diagnostics feature
The Light Path Diagnostics panel is inside the Light Path Diagnostics drawer on the
front right of the server. When you press on the front of the Light Path Diagnostics
drawer, the Light Path Diagnostic panel is exposed.
The following illustration shows the location of the diagnostics panel. See “The
diagnostics panel” on page 37 for information about identifying problems using the
Light Path Diagnostic LEDs.
The system-error LED on the operator information panel is lit when certain system
errors occur. If the system-error LED on the server is lit, one or more LEDs inside
the server might be lit. Use the Light Path Diagnostics panel to identify the type of

acknowledge a system error but not take immediate action, press the REMIND
button, and place the Light Path Diagnostics feature in Remind mode. The
system-error LED flashes in Remind mode. If a new failure occurs, the system-error
LED is lit again.
The diagnostics panel
The diagnostics panel should be the first place you look for help with identifying
problems. If a system error occurs, the system-error LED on the front of this panel
lit. Press the front of the panel to open the diagnostics panel, and look for any lit
LEDs. These lit LEDs can help you identify the possible cause of the error. Make a
note of any LEDs that are lit, and then close the panel.
LEDs on the top of the server
You can also use the LEDs on the top of the server to find an error. If the BOARD
LED on the diagnostics panel is lit, pull the server out, and view the top cover. In
the center of the top cover is a set of six LEDs and the system service labels. The
numbers next to the LEDs correspond to the numbers on the system service label.
Note the lit LED, and see the numbered block on the system service label that
corresponds to the lit LED. Then, follow the instructions, if any, in the numbered
block.
LEDs on the system boards
locate the actual component that caused the error, locate the lit LED next to that
component.
For example:
system error has occurred, and you have noted that the CPU LED is lit on the
diagnostics panel. Referring to the LEDs on the top cover, you see that LED 2 is lit.
You then locate the panel on the system service label with the number 2 on it. In
this case, the instructions in the panel tell you that the problem occurred with one of
the microprocessors. Follow the instructions to remove the processor-board
assembly. See “Processor-board assembly” on page 119. Located on the circuit
board is the light-path capacitor switch. Press and hold the switch until you locate
the lit LED next to the defective microprocessor. Follow the instructions in
“Microprocessor and power module” on page 121 and “Installing and replacing a
microprocessor and power module” on page 100 to remove and replace the
microprocessor.

Diagnostic programs, error codes, and messages
Diagnostic error messages indicate that a problem exists. They are not intended to
used to identify a failing part. Troubleshooting and servicing of complex
problems that are indicated by error messages should be performed by trained
service personnel.
Sometimes the first error to occur causes additional errors. In this case, the server
displays more than one error message. Always follow the suggested action
instructions for the first error message that appears.
Chapter 6, “Symptom-to-FRU index,” on page 147 contains the error codes that
might appear in the detailed test log and summary log when the diagnostic
programs are run.
Text messages
The diagnostic text message format is as follows:
Function Name: Result (test specific string)
where:
Function Name
the name of the function being tested when the error occurred. This
corresponds to the function code (fff) shown in the error code format in the
previous section.

Power problems can be difficult to solve. For example, a short circuit can exist
anywhere on any of the power distribution buses. Usually a short circuit will cause
the power subsystem to shut down because of an overcurrent condition.
Follow this general procedure for troubleshooting power problems:
Turn off the server, and disconnect all ac power cords.
Check for loose cables in the power subsystem. Also check for short circuits; for
example, a loose screw might be causing a short circuit on a circuit board.
Remove adapters and disconnect the cables and power connectors to all
internal and external devices until the server is at the minimum configuration
required to start the server (see the note about minimum operating requirements
page 180).
Reconnect all ac power cords, and turn on the server. If the server starts
successfully, replace adapters and devices one at a time until the problem is
isolated. If the server does not start up from the minimal configuration, replace
FRUs of the minimal configuration one at a time until the problem is isolated.
use this method, it is important to know the minimum configuration required for a
system to start (see the minimum configuration requirements at “Undetermined
problems” on page 185).

Troubleshooting the Ethernet controller
problem occurs with the 10/100/1000 Mbps Ethernet controller, use the Ethernet
diagnostic program on the Resource CD to diagnose the problem. For more
information about this CD, see “Ethernet diagnostic tests” on page 70. For
information about the Ethernet error codes and actions to take, see the
documentation on the Resource CD.
Network connection problems
the Ethernet controller cannot connect to the network, check the following
conditions:
Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is
attached but the problem remains, try a different cable.
you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps,
you must use Category 5 or higher cabling.
Determine whether the hub supports auto-negotiation. If it does not, try
configuring the integrated Ethernet controller manually to match the speed and
duplex mode of the hub.
Check the Ethernet controller LEDs on the rear of the server.
These LEDs indicate whether a problem exists with the connector, cable, or hub.
The Ethernet transmit/receive activity LED on the rear of the server is lit when
the Ethernet controller sends or receives data over the Ethernet network. If
the Ethernet transmit/receive activity LED is off, make sure that the hub and
network are operating and that the correct device drivers are installed.
The Ethernet link status LED on the rear of the server is lit when the Ethernet
controller receives a LINK pulse from the hub. If the LED is off, there might be
defective connector or cable or a problem with the hub.
Make sure that you are using the correct device drivers, which are supplied with
v
your server.
Check for operating-system-specific causes for the problem.
Make sure that the device drivers on the client and server are using the same
protocol.
Test the Ethernet controller.
The way the Ethernet controller is tested depends on which operating system
you are using (see the Ethernet controller device driver README files).

Back up all important data before you make changes to disk drives.
For a list of supported options for your server, go to
http://www.ibm.com/pc/us/compat/.
Note:
Some preconfigured servers have a unique list of supported options. See the
software documentation provided with those servers for more information.
System reliability considerations
help ensure proper cooling and system reliability, make sure that:
Each of the drive bays has either a drive or a filler panel installed.
There is space around the server to allow the cooling system to work properly.
Cables for optional adapters are routed according to the instructions that are
provided with the adapters.
All microprocessors have the same cache size and type and the same clock
speed.
For proper cooling, do not leave the cover open for more than 15 minutes.
failed fan is replaced within 48 hours.
The top cover is closed during normal operation.
not remove a defective power supply until a replacement is available.
For redundant and hot-swappable operation, the power supplies are connected to
200-240 V ac.
Working inside a server with power on
Your server supports hot-swap devices and is designed to operate safely while
turned on with the cover removed. Follow these guidelines when you work inside a
server that is turned on:
Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before
working inside the server; do not wear cuff links while you are working inside the
server.
not allow your necktie or scarf to hang inside the server.
Remove jewelry, such as bracelets, rings, necklaces, and loose-fitting wrist
watches.
Remove items from your shirt pocket (such as pens or pencils) that could fall into
the server as you lean over it.

Take care to avoid dropping any metallic objects, such as paper clips, hair pins,
screws, into the server.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective package until
you are ready to install them.
reduce the possibility of electrostatic discharge, observe the following
precautions:
Limit your movement. Movement can cause static electricity to build up around
you.
Handle the device carefully, holding it by its edges or its frame.
not touch solder joints, pins, or exposed printed circuitry.
not leave the device where others can handle and damage it.
While the device is still in its anti-static package, touch it to an unpainted metal
part of the system unit for at least 2 seconds. This drains static electricity from
the package and from your body.
Remove the device from its package, and install it directly into the system unit
without setting down the device. If it is necessary to set down the device, place it
its static-protective package. Do not place the device on your system unit
cover or on a metal surface.
Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.
Wear a properly grounded wrist strap against your skin to help eliminate static
electricity from your body.
Major components of the xSeries 450 server
The orange color on components and labels in the server indicates hot-swap or
hot-plug components. You can install or remove these components while the server
running, provided that the server is configured to support hot-swap and hot-plug
components.
The blue color on components and labels indicates touch points, where a
component can be gripped, a latch moved, and so on.
