Chapter 2. Configuring the server

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

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.

Chapter 2. Configuring the server

To connect the ASM interconnect module to the Remote Supervisor Adapter, complete the following steps.

Attention: To avoid damage to the Ethernet connector, do not plug the ASM

interconnect module into the Remote Supervisor Adapter Ethernet port.

Connect the ASM Interconnect module 1 to the Remote Supervisor Adapter ASM interconnect (peer-to-peer) port 2. This port is on the edge of the Remote Supervisor Adapter that is accessible from the rear of the server and is labeled RS485.

Connect one or two Category 3 or Category 5 Ethernet cables to the other end

the ASM Interconnect module.

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.

Power checkout

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

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).

Chapter 4. Installing options

This chapter provides detailed instructions for installing hardware options in your server.

Installation guidelines

Before you begin to install options in your server, read the following information:

Read the safety information beginning on page 197 and the guidelines in “Handling static-sensitive devices” on page 78. This information will help you work safely with your server or options.

Make sure that you have an adequate number of properly grounded electrical outlets for your server, monitor, and any other devices that you will connect to the server.

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.

v Do

in to

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.
