Hazardous voltage, current, and energy levels might be present. Only a qualified service technician is authorized to remove the covers where the following label is attached.

Statement 15

CAUTION

Make sure that the rack is secured properly to avoid tipping when the server unit is extended.

Notes

Only use a screwdriver tip to push in the lock tabs on the rack slides. A pinch hazard exists if figners are used for this purpose.

DC Power supplies are installed: The DC source must be electrically isolated by double or reinforced insulation from any hazardous DC source. The DC source must be capable of providing up to 350 W of continuous power per feed pair. Connection with a DC source should only be performed by trained service personnel.

Mains DC power disconnect: You are responsible for installing a DC power disconnect for the entire rack unit. This mains disconnect must be readily accessible, and it must be labeled as controlling power to the entire unit, not just to the servers(s).

Grounding the rack installation: To avoid the potential for an electrical shock hazard, you must i nclude a third wire safety ground conductor with the rack installation. The safety grounding conductor must be a minimum 14AWG connected to the earth ground stud on the rear of the server. The safety ground conductor should be connected to the chassis stud with a two hole crimp terminal with a maximum width of 0.25 inch. The nuts on the chassis studs should be installed with a 10 in/lbs torque. The safety ground conductor provides proper grounding only for the server. You must provide additional, proper grounding for the rack and other devices installed in it.

Overcurrent protection: Overcurrent protection circuit breakers must be provided as part of each host equipment rack and must be installed between theDCsourceandtheserver. TheserverisdesignedforaDClinevoltage power source with up to 10 amperes of overcurrent protection per feed pair. If the DC power system for the equipment rack is installed with more than 10 amperes of protection, you must provide supplemental protection for the server. The overall current rating of a server configured with two power supplies is less than 7 amperes.

Temperature: The temperature in which the server operates when installed in an equipment rack, must not go below 5 °C (41 °F) or rise above 40 °C (104 °F). Extreme fluctuations in temperature can cause a variety of problems in your server.

Ventilation: The equipment rack must provide sufficient airflow to the front of the server to maintain proper cooling. The rack must also include ventilation sufficient to exhaust a maximum of 1023 BTUs per hour for the server. The rack selected and the ventilation provided must be suitable to the environment in which the server will be used.

Notices and Statements Used in This Book

The Caution and Danger statements also appear in the multilingual safety information book provided on the Documentation and Resource CD. Each statement is numbered for easy reference to the corresponding statement in the safety book.

Descriptions of the notices and statements that appear in this book are as follows:

• Notes: These notices provide important tips, guidance, or advice.

• Attention: These notices indicate possible damage to programs, devices, or data. An attention

notice is placed just before the instruction or situation in which damage could occur.

• Caution: These statements indicate situations that can be potentially hazardous to you. A

caution statement is placed just before the description of potentially hazardous procedure step or situation.

• Danger: These statements indicate situations that can be potentially lethal or extremely

hazardous to you. A danger statement is placed just before the description of a potentially lethal or extremely hazardous procedure step or situation.

Before You Begin

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

• Become familiar with the information provided in “Handling Static-sensitive Devices” and in

the “Safety Addendum”. These guidelines will help you make changes t o disk drives.

• Make sure that you have an adequate number of properly grounded electrical outlets for your

server, monitor, and any other options that you intend to install.

• Back up all important data before you make changes to disk drives.

• For a list of supported options for the xSeries 343, refer to http://www.ibm.com/pc/compat on

the World Wide Web.

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.

To 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.

• Do not touch solder joints, pins, or exposed printed circuitry.

• Do not leave the device where others can handle and possibly damage the device.

• While the device is still in its anti-static package, touch it to an unpainted metal part of the

system unit for at least two seconds. (This drains static electricity from the package and from your body.)

• Remove the device from its package and install it directly into your system unit without setting

it down. If it is necessary to set the device down, place it in its static-protective package. Do not place the device on your system unit cover or on a metal table.

• Take additional care when handling devices during cold weather because heating reduces

indoor humidity and increases static electricity.

Table 4. Front Panel Features

Item Feature Description Front Panel Switches

C NMI switch A momentary contact switch used to instruct the processor to copy system

memory to the hard drive. Pressing the recessed button with a paper clip or pin puts the server in a halt state for diagnostic purposes and all ow s you to issu e a non•maskable interrupt. After issuing the interrup t, a memory dump can be

performed to determine the cause of the problem. D Power switch Toggles the system power on/off. E Reset switch Reboots and initializes the system. Front Panel Alarm LEDs and Relays F Critical (amber) When continuously lit, indicates the presence of a Critical System Fault. A

critical system fault is an error or event that is detected by the system with a

fatal impact to the system. In this case, the system cannot continue to operate.

An example could be the loss of a large section of memory or other corruption

that renders the system not operational. Additionally, the front panel critical

alarm relay will engage. G Major (amber) When continuously lit, indicates the presence of a Major System Fault. A major

system fault is an error or event that is detected by the system that has

discernable impact to system operation. In this case, the system can continue

to operate but in a “degraded” fashion (reduced performance or loss of

non-fatal feature reduction). An example could be the loss of one of two

mirrored disks. Additionally, the front panel major alarm relay will engage. H Minor (amber) When continuously lit, indicates the presence of a Minor System Fault. A minor

system fault is an error or event that is detected by the system but has little

impact to actual system operation. An example would be a correctable

ECC error. Additionally, the front panel minor alarm relay will engage. I Power (amber) When continuously lit, indicates the presence of a Power System Fault.

Additionally, the front panel power alarm relay will engage. Front Panel Status LEDs J NIC activity LED

K HDD activity

LED (green)

L Main power

LED (green)

Indicates NIC activity.

Indicates any system SCSI hard drive activity.

When continuously lit, indicates the presence of DC power in the server. The

Processor

The server board accommodates one or two Pentium III processors up to 1-26 GHz with 512k cache in the FC-PGA2 package.

Memory

The system board contains six 168-pin DIMM slots each supporting 72-bit ECC (64-bit main memory plus ECC) registered SDRAM DIMMs (PC-133 compatible). You may install a minimum of 128 MB (64 MB x 2) and as much as 6 GB.

Note

Use DIMMs that have been tested for compatibility with the server board. Contact your sales representative or dealer for a current list of approved memory modules.

PCI Riser Slots

The server board has two PCI r iser slots: a 5 V riser that supports 64-bit/33 MHz riser cards and a

3.3 V riser that supports 64-bit/66 MHz riser cards.

• Bus speed up to 66 MHz

• 32 bit memory addressing

• 5 V/3.3 V signaling environment

• Burst transfers of up to 512 Mbps

• 8, 16, 32, or 64-bit data transfers

• Plug and Play ready

• Parity enabled

Video

The server board uses an ATI RAGE XL PCI graphics accelerator with 8 MB of video SDRAM that supports all standard IBM VGA modes. The embedded SVGA video subsystem supports:

• Pixel resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D

• CRT and LCD monitors up to 100 Hz vertical refresh rate

The server board supports disabling of the onboard video through the BIOS setup menu or when a plug in video card i s installed in any of t he PCI slots.

SCSI Controller

The SCSI version of the server board includes an embedded Adaptec AIC-7899W controller providing dual Ultra160 Low Voltage Differential (LVD) SCSI channels.

The SCSI bus is terminated on the server board with active terminators that cannot be disabled. The onboard device must always be at one end of the bus. The device at the other end of the cable is terminated with the active terminator on the SCSI cable installed in the system.

Chassis Description 15

Network Controller

Note

To ensure EMC product regulation compliance for intra-building lighting surges, the system must only be used with shielded LAN cables that are grounded at both ends.

The server board uses two Intel 82550PM Fast Ethernet Controllers and supports two 10Base-T/100Base-TX network subsystems.

On the server board, NIC 1 can be used as both a network interface and server management interface.

NIC Connector and Status LEDs

The 82550 controller drives LEDs on the network interface connector that indicate link/activity on the LAN and 10- or 100-Mbps operation. The green LED indicates network connection when on and TX/RX activity when blinking. The yellow LED indicates 100-Mbps operation when lit.

Network Teaming Features

Note

Using both on-board NICs in a team does not allow the use of NIC 1 for server management access. To support both network teaming features and server management features, a third NIC must be added and teamed to NIC 2.

The network controller provides several options for increasing throughput and fault tolerance when running Linux®:

• Adapter Fault Tolerance (AFT) - provides automatic redundancy for your adapter. If the

primary adapter fails, the secondary takes over. AFT works with any hub or switch.

• Adaptive Load Balancing (ALB) - creates a team of 2 - 6 adapters t o increase transmission

throughput. Also includes AFT. Works with any 10Base-TX or 100Base-TX switch.

• Fast EtherChannel (FEC) or Intel Link Aggregation - cr eates a team of up to 6 adapters to

increase transmission and reception throughput. Also includes AFT. Requires a FEC-enabled switch.

To set up an option, read the instructions in the Linux RH 7.1 readme files.

Adapter Fault Tolerance

Adapter Fault Tolerance (AFT) is a simple, effective, and fail-safe approach to increase the reliability of server connections. AFT gives you the ability to set up link recovery to the server adapter in case of a cable, port, or network interface card failure. By assigning two server adapters as a team, AFT enables you to maintain uninterrupted network performance.

AFT is implemented with two server adapters: a primary adapter and a backup, or secondary, adapter. During normal operation, the backup will have transmit disabled. If the link to the primary adapter fails, the link to the backup adapter automatically takes over.

16 xSeries 343 Hardware Maintenance Manual

Preferred Primary Adapter

With multiple adapters installed, you can specify one as the Preferred Primary adapter. For example if you have a server with a PRO/1000 server adapter as the primary adapter and a PRO/100+ adapter as the secondary, you could configure the PRO/1000 server adapter to be the preferred primary. In this scenario, if the PRO/1000 server adapter fails, the PRO/100+ will take over. Then when the PRO/1000 server adapter is r eplaced, it will automatically revert to being the primary adapter in the team.

If a Preferred Primary is not selected, PROSet will attempt to select the best adapter, based on adapter model and speed.

Mixed Adapter Teaming

AFT supports up to six server adapters per team, in any mix.

Adaptive Load Balancing

Adaptive Load Balancing (ALB) is a simple and efficient way t o increase your server's transmit throughput. With ALB you group server adapters in teams to provide an increased transmit rate (up to 8 Gbps) using a maximum of eight adapters. The ALB software continuously analyzes transmit loading on each adapter and balances the r ate across the adapters as needed. Adapter teams configured for ALB also provide the benefits of AFT. Receive rates remain at 100 Mbps or 1 Gbps depending on the primary adapter’s capability.

To use ALB, you must have 2-6 server adapters installed in your server or workstation and linked to the same network switch.

Cisco Fast EtherChannel

Fast EtherChannel (FEC) is a performance technology developed by Cisco to increase your server's throughput. Unlike ALB, FEC can be configured to increase both transmission and reception channels between your server and switch. FEC works only with FEC-enabled switches, such as the Catalyst 5000 series. With FEC, as you add adapters to your server, you can group them in teams to provide up to 18 Gbps at full duplex, with a maximum of 6 server adapters. The FEC software continuously analyzes loading on each adapter and balances network traffic across the adapters as needed. Adapter teams configured for FEC also provide the benefits of AFT.

To use FEC, you must have 2, 4, or 6 server adapters plus use of both onboard NIC adapters installed in your server and linked to the same FEC-enabled Cisco switch.

Keyboard and Mouse

The keyboard controller is PS/2-compatible. If specified through the System Setup Utility (SSU), the server may be locked automatically if there is no keyboard or mouse activity for a predefined length of time. Once the inactivity (lockout) timer has expired, the keyboard and mouse do not respond until the previously stored password is entered. If a mouse is required, you can either connect a USB mouse to a USB port or a PS/2 mouse to the PS/2 port using the “Y”-splitter cable.

Chassis Description 17

RJ45 Serial Port

The rear RJ45 serial port is a fully functional COM port that supports any standard serial device and provides support for serial concentrators, which typically support RJ45 serial connectors. For server applications that use a serial concentrator to access the server management features of the baseboard, a standard 8-pin CAT-5 cable from the serial concentrator is plugged directly into the rear RJ45 serial port. The 8 pins of the RJ45 connector can be configured to match either of two pin-out standards used by serial port concentrators. T o accommodate either standard, the J6A2 jumper block located directly behind the rear RJ45 serial port must be jumpered appropriately according to which standard is desired.

Note

The RJ45 serial port’s default configuration is DSR. For serial concentrators requiring a DCD signal, configure the jumper block as shown in Figure 39.

For serial concentrators that require a DCD signal, configure the J6A2 jumper block as shown in Figure 39.

For those server applications requiring a DB9 serial connector, use an 8-pin RJ45-to-DB9 adapter. Table 6 defines the pin-out required for the adapter to provide RS232 support.

Table 6. Rear COM2 Port Adapter Pin-out

RJ45 Signal Abbreviation DB9

1 Request to Send RTS 7 2 Data Terminal Ready DTR 4 3 Transmitted Data TD 3 4 Signal Ground SGND 5 5 Ring Indicator RI 9 6 Received Data RD 2 7 DCD or DSR DCD/DSR 1 or 6 8 Clear To Send CTS 8

Note

The RJ45-to-DB9 adapter should match the configuration of the serial device used. One of two pin-out configurations are used depending on whether the serial device requires a DSR or DCD signal. The final adapter configuration should also match the desired pin-out of the RJ45 connector, as it can also be configured to support either DSR or DCD.

ACPI

The server board supports the Advanced Configuration and Power Interface (ACPI) as defined by the ACPI 1.0 and PC97 specifications. An ACPI aware operating system can put the system into a state where the hard drives spin down, the system fans stop, and all processing is halted. However, the power supply will still be on and the processors will still be dissipating some power, so the power supply fans will still run.

18 xSeries 343 Hardware Maintenance Manual

The server board supports sleep states s0, s1, s4, and s5:

• s0: Normal running state.

• s1: Processor sleep state. No context will be lost in this state and the processor caches will

maintain coherency.

• s4: Hibernate or Save to Disk: The memory and machine state are saved to disk. Pressing the

power button or other wakeup event will restore the system state from the disk and resume normal operation. This assumes that no hardware changes have been made to the system while it was off.

• s5: Soft off: Only the RTC section of the CSB and the BMC are running in this state. No

context is saved by the OS or hardware.

Note

The system is off only when the DC power cable is disconnected.

Security

Software Locks

The BIOS Setup and the System Setup Utility (SSU) provide a number of security features to prevent unauthorized or accidental access to the system. Once the security measures are enabled, you can access the system only after you enter the correct password(s). For example:

• Enable the keyboard lockout timer s o that the server requires a password to reactivate the keyboard and mouse after a specified time out period1 to 120 minutes.

• Set and enable a supervisor password.

• Set and enable a user password.

• Set secure mode to prevent keyboard or mouse input and to prevent use of the front panel reset

and power switches.

• Activate a hot key combination to enter secure mode quickly.

• Disable writing to the diskette drive when secure mode is set.

• Disable access to the boot sector of the operating system hard disk drive.

Using Passwords

You can set either the user password, the supervisor password, or both passwords. If only the user password is set, you:

• Must enter the user password to enter BIOS Setup or the SSU.

• Must enter the user password to boot the server if Password on Boot is enabled in either the

BIOS Setup or SSU.

• Must enter the user password to exit secure mode.

If only the supervisor password is set, you:

• Must enter the supervisor password to enter BIOS Setup or the SSU.

• Must enter the supervisor password to boot the server if Password on Boot is enabled in either

the BIOS Setup or SSU.

• Must enter the supervisor password t o exit secure mode.

Chassis Description 19

If both passwords are set, you:

• May enter the user password to enter BIOS Setup or the SSU. However, you will not be able to change many of the options.

• Must enter the supervisor password if you want to enter BIOS Setup or the SSU and have access to all of the options.

• May enter either password to boot the server if Password on Boot is enabled in either the BIOS Setup or SSU.

• May enter either password to exit secure mode.

Secure Mode

Configure and enable the secure boot mode by using the SSU. When secure mode is in effect:

• You can boot the server and the operating system will run, but you must enter the user password to use the keyboard or mouse.

• You cannot turn off system power or reset the server from the front panel switches.

• Secure mode has no effect on functions enabled via remote server management or power

control via the watchdog timer.

Taking the server out of secure mode does not change the s tate of system power. That is, if you press and release the power switch while secure mode is in effect, the system will not be powered off when secure mode is later removed. However, if the front panel power switch remains depressed when secure mode is removed, the server will be powered off.

Summary of Software Security Features

Table 7 lists the software security features and describes what protection each offers. In general, to enable or set the features listed here, you must run the SSU and go to the Security Subsystem Group, menu. The table also refers to other SSU menus and to the Setup utility.

Table 7. Software Security Features

Feature Description

Secure mode How to enter secure mode:

Setting and enabling passwords automatically places the system in secure mode. If you set a hot-key combination (through Setup), you can secure the system

simply by pressing the key combination. This means you do not have to wait for the inactivity time-out period.

When the system is in secure mode: The server can boot and run the operating system, but mouse and keyboard input

is not accepted until the user password is entered. At boot time, if a CD is detected in the CD-ROM drive or a diskette in drive A, the

system prompts for a password. When the password is entered, the server boots from CD or diskette and disables the secure mode.

If there is no CD in the CD-ROM drive or diskette in drive A, the server boots from drive C and automatically goes into secure mode. All enabled secur e mode features go into effect at boot time.

To leave secure mode: Enter the correct password(s).

Specify the boot sequence

In secure mode, the server will not boot from or write to a diskette unless a password is entered.

To write protect access to diskette whether the server is in secure mode or not, use the Setup main menu, Floppy Options, and specify Floppy Access as read only.

Specify and enable an inactivity time out period of from 1 to 120 minutes. If no keyboard or mouse action occurs for the specified period, attempted keyboard

and mouse input will not be accepted. The monitor display will go blank, and the diskette drive will be write protected

(if these security features are enabled through Setup). To resume activity: Enter the correct password(s).

To control access to setting or changing the system configuration, set a supervisor password and enable it through Setup.

If both the supervisor and user passwords are enabled, either can be used to boot the server or enable the keyboard and/or mouse, but only the supervisor password will allow Setup to be changed.

To disable a password, change it to a blank entry or press CTRL-D in the Change Password menu of the Supervisor Password Option menu found in the Security Subsystem Group.

To clear the password if you cannot access Setup, change the Cle ar Password jumper (see Chapter 5).

To control access to using the system, set a user password and enable it through Setup.

To disable a password, change it to a blank entry or press CTRL-D in the Change Password menu of the User Password Option menu found in the Security Subsystem Group.

To clear the password if you cannot access Setup, change the Cle ar Password jumper (see Chapter 5).

The system can boot with or without a keyboard. During POST, before the system completes the boot sequence, the BIOS automatically detects and tests the keyboard if it is present and displays a message.

The sequence that you specify in setup will determine the bo ot ord er. If secure mode is enabled (a user password is set), then you will be prompted for a password before the server fully boots. If secure mode is enabled and the “Secure Boot Mode” option is also enabled, the server will fully boot but will require a password before accepting any keyboard or mouse input.

Introduction

The xSeries343 server system uses a -48 to -60 VDC input switching power subsystem, which provides up to 350 Watts with -48 to -60 VDC input and with current and remote sense regulation. The power subsystem consists of one or two 350-Watt power supply modules. A system with two modules forms a redundant, hot-swappable (1+1) power subsystem.

Interface Requirements

DC Input

The DC power source may produce hazardous voltage levels exceeding -60 VDC and high energy levels above 240VA that may cause electric shock or burns. All DC input connections should be made only by a qualified service person only to prevent injury. All wiring terminals connected to the DC input terminal block must be fully insulated with no exposed bare metal.

DC Output Connectors

The power subsystem DC power and control signals are interfaced to the server system via wire harnesses when the power supply modules are inserted into the power subsystem enclosure. The safety ground pin of the power supply module is the first pin to connect and the last to disconnect when the module is being inserted or removed from the power subsystem housing. In addition to the 5 V Standby, -12 V, +3.3 V, +5 V and +12 V DC outputs, the following signals and output pins are included:

• +3.3 VDC remote sense

• +5 VDC remote sense

• +12 VDC remote sense

• Remote sense return

• Power Subsystem On (DC PWR enable)

• Power Good

• I

PS Failure, PS Presence, PS Predictive Fail, +12 V Mon, +5 V Mon, and the 5 V Standby rails

failure are being monitored via an I

C interface chip.

Power Supply Module LED Indicators

There is a single bi-color LED to indicate power supply status visible on the back of the system. Table 8 shows the conditions confirmed by the LED indicators.

Peripheral Bay

The peripheral bay consists of the following two bays for removable media:

• Low profile media bay 1 – for a ½-inch Floppy drive

• Low profile media bay 2 – for a ½-inch CD-ROM drive

Hard Drive Tray

The hard drive tray supports two 3.5-inch x 1.0-inch Ultra160 SCSI hard disk drives (non-SCA). The hard drive tray is designed to accept 15 K RPM (and below) hard drives t hat consume up to 18 Watts of power.

Chassis Description 25

Cooling Subsystem

The cooling subsystem contains a fan array (as shown in Figure 9) consisting of two 80 x 38 mm fans and two 40 x 28 mm fans to cool the server board and other components. A fan failure is indicated by one of the fault LEDs located on the front panel.

OM12820

Figure 9. Fan Array with Four System Fans Installed

Air flows through the bezel, over the peripheral bay and the hard drive tray, passes through the fans, over the server board, and exhausts through the rear of the chassis.

Each fan provides a tachometer signal output to the server board to indicate a fan failure.

Ambient Temperature Control

The server board contains a pulse-width-modulation (PWM) circuit, that cycles the 12 VDC fan voltage to provide quiet operation when system baseboard temperature is low, and there are no fan failures. Under normal baseboard temperature conditions (less than 45 °C), the fan power circuit supplies an effective fan voltage of 7.0 VDC. When the baseboard temperature exceeds 45 °C, the fan control circuit ceases cycling and delivers 12 VDC. Following a baseboard temperature excursion above 45 °C the fan voltage does not reenter PWM mode until the baseboard temperature drops below 45 °C and all fans are operational.

The cooling subsystem’ design meets acoustic and thermal requirements at the lower fan speed settings. At the higher fan speed settings, thermal requirements are met for the maximum ambient temperatures but acoustic requirements are not met.

26 xSeries 343 Hardware Maintenance Manual

Server Management Summary

The server board’s server management architecture features a board management controller (BMC), which autonomously monitors server status and provides the interface to server management control functions. The BMC is responsible for controlling system power, resets, monitoring voltages, temperatures, fans, and communicating with secondary controllers on its Intelligent Platform Management Bus (IPMB).

The functions of each controller are summarized in the following sections.

4 Configuration Software and Utilities

This chapter describes the Power-On Self-Test (POST) and server configuration utilities. The table below briefly describes the utilities.

Table 11. Configuration Utilities

Utility Description and brief procedure Page

BIOS Setup If the system does not have a diskette drive, or the drive is

disabled or incorrectly configured, u se Setup to enabl e it . Or, you can move the CMOS jumper on the server board from the

default setting (Protect CMOS memory) to the Clear setting; this will allow most server configurations to boot. Then run the SSU to

configure the server. BIOS Upgrade Utility Use to upgrade the BIOS. 45 System Setup Utility

(SSU)

FRUSDR Load Utility Use to update the Field Replacement Unit (FRU), Sensor Data

Firmware Update Utility Use to update the Firmware. 56 Using the Adaptec SCSI

Utility

Use for viewing and clearing the system event log, viewing the

system management FRU information, or viewing the system

management SDR repository.

Record (SDR), and SM BIOS (SMB) flash components.

Use to configure or view the settings of the SCSI host adapter and

onboard SCSI devices in the server.

Using BIOS Setup

This section describes the BIOS Setup options. Use Setup t o change the server configuration defaults. You can run Setup with or without an operating system being present. Setup stores most of the configuration values in battery backed CMOS; the rest of the values are stored in flash memory. The values take effect when you boot the server. POST uses these values to configure the hardware; if the values a nd the actual hardware do not agree, POST generates an error message. You must then run Setup to specify the correct configuration.

Recording Your Setup Settings

If the default values ever need to be restored (after a CMOS clear, for example), you must run Setup again. Referring to the worksheets could make your task easier.

If You Cannot Access Setup

If the diskette drive is incorrectly configured so that you cannot access it to run a utility from a diskette, you may need to clear CMOS memory. You will need to open the server, change a jumper setting, use Setup to check and set diskette drive options, and change the jumper back.

Starting Setup

After rebooting, you will see this prompt:

Press <F2> to enter SETUP

Note

If the BIOS setup option “POST Diagnostic Screen” is enabled (Default), you will not see the message “Press <F2> to enter SETUP”. This message is hidden by the Manufacturer’s Splash screen. To see the message, press the <ESC> key while the splash screen is displayed. This will temporarily disable the splash screen allowing you to see the message.

If CMOS/NVRAM is corrupted, you will see other prompts but not the <F2> prompt:

Warning: cmos checksum invalid Warning: cmos time and date not set

In this condition, the BIOS will load default values for CMOS and attempt to boot.

Configuration Software and Utilities 43

Upgrading the BIOS

Preparing for the Upgrade

Before you upgrade the BIOS, prepare for the upgrade by recording the current BIOS settings, obtaining the upgrade utility, and making a copy of the current BIOS.

Recording the Current BIOS Settings

1. Boot the computer and press <F2> when you see the message:

Press <F2> Key if you want to run SETUP

2. Write down the current settings in the BIOS Setup program.

Note

Do not skip step 2. You will need these settings to configure your computer at the end of the procedure.

Obtaining the Upgrade Utility

You can upgrade to a new version of the BIOS using the new BIOS files and the BIOS upgrade utility, IFLASH.EXE. You can obtain the BIOS upgrade file and the IFLASH.EXE utility through your computer supplier or from the IBM Customer Support website at http://www.ibm.com/pc/support.

Note

Please review the instructions distributed with the upgrade utility before attempting a BIOS upgrade.

This upgrade utility allows you to:

• Upgrade the BIOS in flash memory.

• Update the language section of the BIOS.

The following steps explain how to upgrade the BIOS.

44 xSeries 343 Hardware Maintenance Manual

Creating the BIOS Upgrade Diskette

The BIOS upgrade file is a compressed self-extracting archive that contains the files you need to upgrade the BIOS.

1. Insert the bootable diskette into the diskette drive.

2. Extract the contents of the BIOS.EXE file onto the bootable diskette. To do this, simply type the filename (with or without the extension) at the a:\ prompt, for example “BIOS.EXE”.

3. You will be prompted to confirm a folder in which to store the extracted files. The BIOS upgrade image is extracted in the specified folder.

Upgrading the BIOS

1. Place the bootable diskette containing the BIOS update files into the diskette drive of your system. Boot the system with the diskette in the drive.

2. At this point you have a choice of two options. Press 1 and ENTER to automatically update the system B IOS. This will update the system BIOS and reset the system. Press 2 and ENTER to update the User Binary and reset the system.

3. Wait while the BIOS files are updated. Do not power down the system during the BIOS update process! The system will reset automatically when the BIOS update process is completed. Remove the diskette from the diskette drive.

4. Check to make sure the BIOS version displayed during POST is the new version as the system reboots.

5. Enter Setup by pressing the F2 key during boot. Once in Setup, press the F9 and ENTER to set the parameters back to default values.

6. Re-enter the values you wrote down at the beginning of this process. Press F10 and ENTER to exit BIOS Setup and Save Changes.

7. If you do not set the CMOS values back to defaults using the F9 key, the system may function erratically.

Note

You may encounter a CMOS Checksum error or other problem after reboot. Try shutting down the system and booting up again. CMOS checksum errors require that you enter Setup, check your settings, save your settings, and exit Setup.

Configuration Software and Utilities 45

Recovering the BIOS

It is unlikely that anything will interrupt the BIOS upgrade; however, if an interruption occurs, the BIOS could be damaged. The following steps explain how to recover t he BIOS if an upgrade fails.

Note

Because of the small amount of code available in the non-erasable boot block area, there is no video support. You will not see anything on the screen during the procedure. Monitor the procedure by listening to the speaker.

You must boot to DOS. The BIOS recovery diskette will not be created

Note

correctly under the DOS window of a Windows operating system.

1. Get the BIOS update file package from IBM iBL or http://www.ibm.com/pc/support.

2. A file called “crisis.zip” is one of the files included with each xSeries 343 BIOS release file package. Unzip the “crisis.zip” file to a directory on your hard drive.

3. Format a blank diskette (the diskette should not be a bootable DOS diskette). Insert the diskette into the diskette drive.

4. From the DOS, run the “crisdisk.bat” file from the directory you created on your hard drive. Follow the instructions on the screen to create the BIOS recovery diskette.

The BIOS recovery diskette will not be created correctly under the DOS window of a Windows operating system. You must boot to a DOS system to create the BIOS recovery diskette.

5. Power off the xSeries 343 system, unplug/disconnect the power cord, and remove the chassis panel.

6. Remove the spare jumper from pins 11-12 on jumper block 1J15 and install it on pins 9-10 (BIOS Recovery) of jumper block 1J15.

7. Insert the BIOS recovery diskette into the diskette drive.

8. Reinstall the chassis panel, plug-in/reconnect the power connection, and power-on the system.

9. The screen will remain blank while the BIOS Recovery is performed. A number of beeps will occur during the BIOS update. The diskette drive access light will not turn off when the BIOS recovery is completed. Allow four minutes for the BIOS recovery to complete. If a POST card is installed in a PCI slot during the BIOS recovery, you can tell that the BIOS recovery is complete when code “EC” is displayed. When the BIOS Recovery is complete, it is safe to power off the system.

10. Power off the system, unplug/disconnect the power cord, and remove the chassis panel.

11. Remove the BIOS Recovery jumper from pins 9-10 and store the jumper on pins 11-12.

12. Replace the chassis panel; plug in the power cord(s), and power on the system.

13. Perform a CMOS clear following the BIOS recovery.

46 xSeries 343 Hardware Maintenance Manual

Changing the BIOS Language

You can use the BIOS upgrade utility to change the language the BIOS uses for messages and the Setup program. Use a bootable diskette containing the Intel Flash Utility and language files.

1. Boot the computer with the bootable diskette in drive A. The BIOS upgrade utility screen appears.

2. Select Update Flash Memory From a File.

3. Select Update Language Set. Press <Enter>.

4. Select drive A and use the arrow keys to select the correct

.lng file. Press <Enter>.

Using the System Setup Utility

The System Setup Utility (SSU) is on the Documentation and Resource CD shipped with the server board. The SSU provides a graphical user interface (GUI) over an extensible framework for server configuration. The SSU framework supports the following functions and capabilities:

• Allows viewing and clearing of the system’s critical event log

• Allows the viewing of the system management FRU information

• Allows the viewing of the system management SDR repository

What You Need to Do

The SSU may be run directly from the Documentation and Resource CD (by booting t he server system to the CD and selecting “Utilities”) or from a set of DOS diskettes.

If you choose to run the SSU from a set of DOS diskettes, you must create the SSU diskettes from the Documentation and Resource CD by booting to the CD and selecting “Create Diskettes.” Alternatively, if you have a Windows 95 or Windows NT workstation, you can insert the CD into that system and create diskettes from the “Utilities” menu of the graphical user interface.

If your diskette drive is disabled, or improperly configured, you must use the flash resident Setup utility to enable it so that you can use the SSU. If necessary, you can disable the drive after you exit the SSU. Information entered using the SSU overrides any entered using Setup.

Running the SSU from the CD

Running the ssu.bat file provided on the SSU media starts the SSU. If the server boots directly from the SSU media, the ssu.bat file is automatically run. If it boots from a different media, the SSU can be started manually or by another application. When the SSU starts in the local execution mode (the default mode), the SSU accepts input from the keyboard and/or mouse. The SSU presents a VGA based Graphical User Interface (GUI) on the primary monitor.

Configuration Software and Utilities 47

The SSU runs from writable, non-writable, removable, and non-removable media. If the SSU is run from non-writable media, user preference settings (such as screen colors) cannot be saved.

The SSU supports the ROM-DOS V6.22 operating system. It may run on other ROM-DOS-compatible operating systems but they are not supported. The SSU will not operate from a “DOS box” running under an operating system such as Windows.

Running the SSU Remotely via an Emergency Management Card

Using graphical hardware redirection via the emergency management card 2, you can see the SSU Console in VGA graphics mode, control the mouse, and control the keyboard from a local system connected to a remote server by a network or modem.

The emergency management card 2 provides video memory, keyboard, and mouse redirection support. Video memory and user input are sent to a remote location through either a modem or Ethernet link and displayed by the Remote Control console. This solution requires an emergency management card 2 card installed in the remote server and the Remote Control software available on the local system. The SSU will execute exclusively on the remote server. Any files required for the SSU to execute must be on the remote server.

Starting the SSU

SSU consists of a collection of task-oriented modules plugged into a common framework called the Application Framework (AF). The Application Framework provides a launching point for individual tasks and a location for setting customization information. The SSU requires the availability of the AF.INI, AF.HLP, plus any .ADN files and their associated .HLP and .INI files.

1. After creating set of three SSU diskettes from the CD: Insert the first SSU diskette in drive A, and press the reset button or <Ctrl+Alt+Del> to reboot your server from the diskette. Insert the second diskette when prompted.

2. Directly from the Documentation and Resource CD: Insert the Documentation and Resource CD into your CD ROM drive and press the reset button or <Ctrl-Alt-Del> to reboot. When prompted to do so, press <F2> to enter BIOS Setup. From the Boot Menu, select the Boot Device Priority option and then select CD-ROM as your primary boot device. Save those settings and exit BIOS Setup. The server will boot from the CD-ROM and display a menu of options. Follow the instructions in the menu to start the SSU.

3. When the SSU title appears on the screen, press <Enter> to continue.

4. The mouse driver loads if it is available; press <Enter> to continue.

5. This message appears:

Please wait while the Application Framework loads....

6. When the main window of the SSU appears, you can customize the user interface before continuing.

48 xSeries 343 Hardware Maintenance Manual

Customizing the SSU

The SSU lets you customize the user interface according to your preferences. The AF sets these preferences and saves them in the AF.INI file so that they take effect the next time you start the SSU. There are four user customizable settings:

• Color: T his button lets you change the default colors associated with different items on the screen with predefined color combinations. The color changes are instantaneous.

• Mode: This button lets you set the desired expertise level.  Novice  Intermediate  Expert

The expertise level determines which tasks are visible in the Available Tasks section and what action each task performs. For a new mode setting to take effect, you must exit the SSU and restart it.

• Language: This button lets you change the strings in the SSU to strings of the appropriate language. For a new language setting to take effect, you must exit the SSU and restart it.

• Other: This button lets you change other miscellaneous options in the SSU. The changes take effect immediately.

To change the interface default values:

Use the mouse to click on the proper button in the Preferences section of the SSU Main window,

Or, Use the tab and arrow keys to highlight the desired button, and press the spacebar or <Enter>, Or, Access the menu bar with the mouse or hot keys (Alt + underlined letter).

Note

If you run the SSU from non-writable media (like a CD-ROM), these preferences will be lost when you exit the SSU.

Configuration Software and Utilities 49

Launching a Task

It is possible to have many tasks open at the same time, although some tasks may require complete control to avoid possible conflicts. The tasks achieve complete control by keeping the task as the center of operation until you close the task window.

FRU/SDR Load Utility

The Field Replacement Unit (FRU) and Sensor Data Record (SDR) Load Utility is a DOS-based program used to update the server management subsystem’s product level FRU, SDR, and the SM BIOS (SMB) nonvolatile storage components (EEPROMs). The load utility:

• Discovers the product configuration based on instructions in a master configuration file

• Displays the FRU information

• Updates the nonvolatile storage device (EEPROM) associated with the Baseboard Management

Controller (BMC) t hat holds the SDR and FRU area

• Updates the SMB area located in the BIOS nonvolatile storage device

• Generically handles FRU devices that may not be associated with the BMC

When to Run the FRU/SDR Load Utility

You should run the FRU/SDR Load Utility each time you upgrade or replace the hardware in your server, excluding add-in boards, hard drives, and RAM. For example, when you upgrade your processor or add a second power module to the 1+1 power supply.

Because the firmware must reload to properly initialize the sensors after programming, turn the server off and unplug/disconnect the power cords from the server. Wait approximately 30 seconds, and plug-in/reconnect the power cords.

What You Need to Do

The FRU/SDR Load Utility may be run directly from the Documentation and Resource CD or from a diskette you create from the CD. It can be extracted from the CD by booting to the CD and selecting “Make Diskettes” or by inserting the CD into a PC running Windows 95 or NT and selecting the “Utilities” section.

Note

If your diskette drive is disabled, or improperly configured, you must use BIOS Setup to enable it. If necessary, you can disable the drive after you are done with the FRU/SDR utility.

How You Use the FRU/SDR Load Utility

This utility is compatible with ROM-DOS Version 6.22, MS-DOS Version 6.22, and later versions. The utility accepts CFG, SDR and FRU load files. The executable file for the utility is frusdr.exe. The utility requires the following supporting files:

• One or more .fru files describing the system’s field replaceable units

• A .cfg file describing the system configuration

• A .sdr file describing the sensors in the system

Command Line Format

The basic command line format is

frusdr [/?] [/h] [/d {smb, fru, sdr}] [/cfg filename.cfg] /p

Command Description

frusdr Is the name of the utility /? Or /h Displays usage information /d {smb, fru, sdr} Only displays requested area /cfg filename.cfg Uses custom CFG file /p Pause between blocks of data

Configuration Software and Utilities 53

Parsing the Command Line

The FRU/SDR Load Utility allows only one command line function at a time. A command line function may consist of two parameters; for example: cfg filename.cfg. Any invalid parameters result in displaying an error message and exiting the program. You can use either a slash (/) or a minus sign (-) to specify command line options. The /p flag may be used in conjunction with any of the other options.

Displaying Usage Information

When the utility is run with the /? or /h command line flags, the following message is displayed:

FRU & SDR Load Utility Version X.XX Usage: Frusdr Is the name of the utility.

/? Or /h Displays usage information. /d {smb,fru,sdr} Only displays requested area. /cfg filename.cfg Uses custom CFG file. /p Pause between blocks of data.

Displaying a Given Area

When the utility is run with the /d SMB, /d FRU, or /d SDR command line flag, the indicated area is displayed. Each area represents a sensor; one sensor for each instrumented device in the server. If the given display function fails because of an inability to parse the data present or a hardware failure, the utility displays an error message and exits.

Displaying SM BIOS Area

The SM BIOS area is displayed in ASCII format when the field is ASCII or as a number when the field is a number. Each SM BIOS area displayed is headed with the SM BIOS area designated name. Each field has a field name header followed by the field in ASCII or as a number.

Displaying FRU Area

The FRU area is displayed in ASCII format when the field is ASCII or as a number when the field is a number. Each FRU area displayed is headed with the FRU area designated name. Each field has a field name header followed by the field in ASCII or as a number. The Board, Chassis, and Product FRU areas end with an END OF FIELDS CODE that indicates there is no more data in this area. The Internal Use area is displayed in hex format, 16 bytes per line.

Displaying SDR Area

The SDR nonvolatile storage area is displayed in the following hex format. A Sensor Record Number X header separates the data; where X is the number of that sensor record in the SDR area. The next line after the header is the sensor record data in hex format delineated by spaces. Each line holds up to 16 bytes. The data on each line is followed by the same data in ASCII format; nonprintable characters are substituted by a period (.).

54 xSeries 343 Hardware Maintenance Manual

Using Specified CFG File

The utility can be run with the command line parameter of -cfg filename.cfg. The filename can be any DOS accepted, eight-character filename string. The utility loads the specified CFG file and uses the entries in the configuration file to probe the hardware and to select the proper SDRs to load into nonvolatile storage.

Displaying Utility Title and Version

The utility displays its title:

FRU & SDR Load Utility, Version X.XX

Where X.XX is the revision number for the utility.

Configuration File

The configuration file is in ASCII text. The utility executes commands formed by the strings present in the configuration file. These commands cause the utility to perform various tasks needed to ultimately load the proper SDRs into the nonvolatile storage of the BMC and possibly generic FRU devices. Some of the commands may be interactive and require you to make a choice.

Prompting for Product Level FRU Information

Through the use of a Configuration File, the utility may prompt you for FRU information.

Filtering Sensor Data Record From the SDR File

The MASTER.SDR file has all the possible SDRs for the system. These records may need to be filtered based on the current product configuration. The configuration file directs the filtering of the SDRs.

Updating the SDR Nonvolatile Storage Area

After the utility validates the header area of the supplied SDR file, it updates the SDR repository area. Before programming, the utility clears the SDR repository area. The SDR file is loaded via the .cfg File. Then the utility filters all tagged SDRs depending on the product configuration set in the Configuration File. Non-tagged SDRs are automatically programmed. The utility also copies all written SDRs to the SDR.TMP file. It contains an image of what was loaded, and the TMP file is also useful for debugging the server.

Updating FRU Nonvolatile Storage Area

After the configuration is determined, the utility updates the FRU nonvolatile storage area. First it verifies the Common Header area and checksum from the specified FRU file. The Internal Use Area is read out of the specified .FRU file and is programmed into the nonvolatile storage. The Chassis, Board, Product and MultiRecord areas are read out of the specified .FRU file, if they exist, then those areas are programmed into the FRU nonvolatile storage. All the areas are also written to the FRU.TMP file, which is useful for debugging the server.

Updating SMB FRU Nonvolatile Storage Area

After programming the BMC FRU area, the corresponding SMB fields are automatically updated when the server is re-booted.
