STL2 Troubleshooting

Welcome to the STL2 server platform. In the unlikely event you do encounter issues, this guide will help you

troubleshoot & identify possible problem areas. If you are unable to resolve a problem using this guide,

please call our help desk. This guide will assist you collecting the data we will need to identify and resolve

the issue you are experiencing. Each issue includes suggestions that may help you and a list of information

we will need to assist you should you need to call. Please visit the Intel Customer Support website for

updated versions of this document and additional product information at:

http://support.intel.com/support/motherboards/server/STL2

I. Boot Issues

1. My server will not power on.

A. Please check for the following possibilities:

• Is the server AC power cord securely plugged into the power supply?

• Is the server plugged into a "powered on" power strip?

• The SC5000 redundant power supply has two power switches on the back of the power

supply next to the fan, are they switched on?

• The chassis and power supply chosen for use with the STL2 server board needs to

properly support the thermal, EMI and power requirements for the board. The system

integrator should calculate a power budget for all items being integrated into the system

to be sure that the available power is not exceeded. A worksheet for calculating the

power budget is contained in the STL2 Product Guide. Failure to follow the power

budget guidelines may result in a system that will not boot or may function erratically.

• When integrating the STL2 server board into the chassis metal standoffs were used to

support the server board. Verify that all standoffs are in the correct locations by

consulting the board diagram in the Quick Start Guide or the Product Guide. All metal

standoffs must be located under a board hole with a tinned ground plane ring around it.

Improperly locating a standoff may result in the board shorting to the frame and may

damage the board or its components.

• The STL2 server board is designed for operation with Pentium® III Processors

utilizing133MHz front side bus. The system may not power on using non-compatible

processors, use of non-compatible processors may damage the processors and/or server

board. Supported processors are listed in the Technical Product Specification available

on the support website: http://support.intel.com/support/motherboards/server/STL2

• If you are using the redundant power version of the Intel SC5000 server chassis, the SSI

compliant power supply includes a power supply signal plug that must be plugged on to

the header on the server board labeled “Pwr Sup. Signal”. This cable supplies the 3.3v

sense signal to the logic of the power supply and must be connected or the power supply

will not allow the system to power on. The power supply signal connector is located

along the edge of the board near the secondary processor connector. Verify that the

power supply cables are plugged in to the proper connectors.

• The STL2 requires 0.8A of 5-volt standby power be supplied to the baseboard in order to

power on. Most ATX compliant power supplies and all SSI compliant power supplies

supply sufficient 5-volt standby current. Standby power is required to enable the server

management features of the server board and the server board will NOT power on

without it. The power supply of the SC5000 chassis provides this standby current. If you

Intel Server Board Troubleshooting Guide -5-

are using a different power supply, verify that it provides the required 0.8A of 5-volt

standby power.

• Remove all non-essential add-in cards and see if the server boots using just the on-board

components. If successful, add the cards back in one at a time with a reboot in between

to see if you can pinpoint a suspect card.

• Remove the memory reseat it, try different memory modules and be sure they are on the

tested memory list. The STL2 server board requires the use of PC133 registered memory

with a CAS latency of 2 or 3 meeting the JEDEC specification.

• Remove the Processor and Terminator card and reseat them.

• Verify that the Floppy and IDE data cables are properly connected so that pin 1 of the

cable (the red edge of the ribbon cable is pin 1) is connected to pin 1 on the device and on

the server board connection. Failure to properly orient these cables may result in the

system not booting.

B. Though it is unlikely that the STL2 will not boot, there are many reasons why it may not boot. If

you are unable to resolve this issue, please fill out the included customer support form and call

Intel Customer Support. Please note the answers to the questions below.

• What memory is being used? Is it on the tested memory list? See

http://support.intel.com/support/motherboards/server/STL2 for the latest tested memory

list.

• Are any front panel lights on the chassis you are using?

• Are the Power Supply Fans spinning? Are any system fans spinning?

• Does the system beep? See Issue 2

• Please note what is displayed on the monitor or what sounds are emanating from the

server.

• If you have a post code card, note the Post Code where the system stops and report that

information as well.

2. My server gives a beep code and halts.

A. Most likely, these beeps are what are known as “beep codes.” They identify system events in case

video fails to display. The following is a list of common “beep codes.”

Beep

Code Meaning

1-2-2-3 BIOS ROM checksum error, update BIOS using BIOS recovery

1-3-4-1 RAM failure, reseat memory, try other tested memory, use Registered ECC

PC133 memory

1-3-4-3 RAM failure, reseat memory, try other tested memory, use Registered ECC

PC133 memory

1-3-3-1 RAM failure, reseat memory, try other tested memory, use Registered ECC

PC133 memory

1-2 Video failure, remove all add in cards and test

1 One short beep before boot (Normal Operation)

3. I heard the drives spin up, and my floppy drive light turned on – but I’m not seeing

video.

A. Check the following items:

• Remove any non-essential add in cards and check to see if the server boots. If successful,

try adding the cards one at a time with a reboot in between to try and pinpoint a suspect

card.

Intel Server Board Troubleshooting Guide -6-

• Remove and reseat the memory modules.

• Remove and reseat the Processor / Terminator cards.

• The STL2 server board requires the use of two processors, or one processor and a

processor terminator card. If a single processor is used, it must be installed in the primary

processor slot and a processor termination card must be installed in the secondary

processor slot. In addition, processors must be matched for speed and type, and must be

within one stepping of the other.

• If you are using a switch box to select between different servers, is it switched to the

correct machine?

• When integrating the STL2 server board into the chassis metal standoffs were used to

support the server board. Verify that all standoffs are in the correct locations by

consulting the board diagram in the Quick Start Guide or Product Guide. All metal

standoffs must be located under a board hole with a tinned ground plane ring around it.

Improperly locating a standoff may result in the board shorting to the frame and may

damage the board or its components.

B. If you still can’t get a video image, please fill out the included customer support form and call

Intel Customer Support. Please note the answers to the questions below.

• Is your system making any noises? (see “Issue 2, My server gives a beep code and halts”)

• Are any of your front-panel lights illuminated?

• Are the power supply fans turning? Are any system fans turning?

• If you have a post code card, note what post code the system halts on.

4. I’m installing adapters in my powered-down system, and my system boots up when

I install a PCI adapter!

A. Wake On Lan* (WOL), and other server management features require full time “standby” power.

This means that power is still provided to parts of the system even if the user has turned the

system “off” via the front panel power switch. Additionally, there are signals in the PCI

connectors that tell the system to boot (normally used by server management adapters/NICs).

Plugging in the adapter with AC power cable still attached to the powersupply can cause false

signals to be transmitted commanding the system to boot. Before removing the cover to your

chassis, you should always:

• Turn off the server via the front panel power switch.

• Unplug the AC cord from the back.

B. See also issue 5. If your server is booting automatically, but the helps specified in issue 4 or 5 do

not resolve the problem, please fill out the included customer support form and call Intel

Customer Support. Please pay special attention to the following information:

• What BIOS do you have loaded on the system? (the latest tested BIOS is posted to the

Intel Customer Support Website

http://support.intel.com/support/motherboards/server/STL2).

• What is the PBA or AA number of the baseboard? (The PBA / AA number is located on a

white label near the edge of the board and is printed in the following format: PBA / AA

xxxxxx-xxx).

• What memory is being used? Is it on the tested memory list? See

http://support.intel.com/support/motherboards/server/STL2 for the latest tested memory

list.

Intel Server Board Troubleshooting Guide -7-

5. My system boots up automatically when I power on my power-strip.

A. The STL2 can be configured to save the “last known power state” since the last AC power

connection. The board can be configured so that if you remove AC power before powering down

the system via the front panel power switch, your system will automatically attempt to come back

to the “on” state it was in once you restore AC power.

• This option is configured in the BIOS setup under the System Menu, AC-Link Option.

• Please keep in mind that either unplugging the system or flipping a switch on the power

strip removes AC power.

• Follow the correct A/C removal sequence: Press the front panel button, then remove the

A/C power cord.

B. Allowing your system to fully power up and then power down the system by using the power

switch would correct this problem. If neither of these options fix your problem, fill out the

attached customer support form and call Intel Customer Support. Please have the following

information available:

• What BIOS do you have loaded on the system? (the latest tested BIOS is posted to the

Intel Customer Support Website)

• What is the PBA number of the baseboard? (The PBA number is located on a white label

near the edge of the board and is printed in the following format: PBA xxxxxx-xxx)

• What memory is being used? Is it on the tested memory list? See

http://support.intel.com/support/motherboards/server/STL2 for the latest tested memory

list.

6. The boot up process takes too long.

A. What users typically term “booting” has multiple phases:

• BIOS Power On Self Test (POST): This includes the memory count and the

keyboard/mouse check.

• Option-ROM loading: Each device may load a portion of its operating code or “option

ROM” into memory. This is what the user may see as the messages that come up

identifying the add-in device, e.g. SCSI ROM.

• Operating system boot: During this time, the operating system takes control of the server

and performs whatever checks & setups are necessary for operation. An example of this is

the Windows NT* blue boot up screen.

B. A slow-down at any of these three points can produce what users perceive as a “slow boot.” The

following is a list of items that can produce a slower boot:

• Large memory configurations. Large memory installations can take 1-2 minutes to check.

• Multiple SCSI devices. SCSI device adapters, like many other adapters, have option

ROMs that must be loaded into memory. Detection & option ROM loading takes

additional time. Option ROM scan for non booting devices can be disabled to shorten the

boot process, but care should be taken as this action can render the system not bootable.

• Numerous other adapters. Adapters in general take time to load their option ROMs into

memory.

C. If you require additional support, please fill out the included customer support form and call Intel

Customer Support. Please be prepared to provide the following information:

• Amount of memory in the system.

• What memory is being used? Is it on the tested memory list? See

http://support.intel.com/support/motherboards/server/STL2 for the latest tested memory

list.

• Number and type of adapters in the system (manufacturer and model number).

Intel Server Board Troubleshooting Guide -8-

• The number and type of hard disk drives in the system (manufacturer and model number).

7. I put 1 processor in my system but it doesn’t boot.

A. Check the following:

• Verify that the processor is in the Primary processor slot. Refer to the Quick Start Guide

or the Product Guide for proper installation procedure.

• Verify that the jumper settings for processor clock frequency are set properly. These

jumpers must be must be set to the speed of the processor, the board may not boot or may

behave erratically if these jumpers are not set correctly. They are the 5E1 located

between the 32-bit PCI slot closest to the processors and the 64-bit slot next to it. Correct

jumper settings are located on the configuration label, in the quick start guide, and in the

product guide (on the CD) that shipped with the product. Additional processor and

configuration information can be found on the Intel support web site at

http://support.intel.com/support/motherboards/server/STL2.

• Verify that the processor is seated properly. Remove the processor and reseat it.

• Verify that the terminator card is installed. Remove the terminator card and reseat it.

• The STL2 server board is designed for operation with Pentium® III processors

utilizing133MHz front side bus. The system may not power on using non compatible

processors, use of non compatible processors may damage the processors and / or server

board. Supported processors are listed in the Quick Start Guide, the Product Guide, and

on the Configuration Label accompanying this product. An updated list of supported

processors is available at: http://support.intel.com/support/motherboards/server/STL2

• Does the system beep? Refer to question 2.

B. If you are still having no-boot issues, please fill out the included customer support form and call

Intel Customer Support with the following information ready:

• Does the system beep? What beep code is it giving?

• Does the system show video?

• What memory is installed in the system? Is it on the Intel tested memory list? See

http://support.intel.com/support/motherboards/server/STL2 for the latest tested memory

list.

• What error does the system give?

• What add-in adapters are installed in your system? (Manufacturer and model number)

II. Other Issues

8. The reset button does not function on the SC5000 chassis.

A. Verify that the reset cable plug is properly oriented on the connector P23 of the server board. The

reset button will not function if this connector is improperly oriented. Refer to the Quick Start

Guide or Product User guide for more information.

9. The NMI switch on the front panel of my system does not work

A. The SC5000 Chassis is a universal chassis designed for compatibility with multiple Intel server

boards. As such, not all features of the chassis function with all server boards. When the STL2

server board is integrated in the SC5000 chassis, the NMI switch on the front panel does not

function. Instead, an NMI switch is located on the back I/O panel of the system via a small hole.

To gain access to the NMI switch through the hole, inserting the tip of a pen, pencil, or some

other non-conducting probe and apply a small amount of pressure.

Intel Server Board Troubleshooting Guide -9-

10. My Hard Disk Drives don’t show up in POST.

A. Check the following:

• Are you using 3rd party SCSI adapters? System memory limitations limit the number &

size of option ROMs in the system. If you install to many adapters or adapters that take

up too much space in memory, they may not be able to expand their ROMs and will not

show the hard disk drives connected to them. In addition, some third party SCSI adapters

or RAID controllers do not work together. Try the following:

(i) Verify that the data cable is connected pin 1 to pin 1.

(ii) Verify that the drive power cable is connected.

• If you disconnect your hard drives from the 3rd party adapter and connect them to the on-

board controller, do they show up?

• Verify that the device power cable is firmly connected.

• Are your hard drives properly terminated? (If using the SC5000 chassis, the

Ultra160/LVD SCSI hot swap backplane automatically terminates each device and is

backward compatible with Ultra 2 drives.) However, if you are using Ultra2/Ultra160

drives without a hot swap backplane, a terminator needs to be placed in the last connector

on the SCSI cable. Ultra 2/Ultra160 devices do not provide their own termination logic

like Ultra Wide devices do.

• Check the SCSI ID numbers, SCSI devices must have a unique ID number. This number

is set automatically when using a SCSI hot swap backplane but must be set at the drive if

individually configuring drives on an SCSI cable. ID number should be set starting at 0

and must be set lower than 8 if the drive is to be booted from.

• Verify that the power budget requirements have not been exceeded; refer to question 1

above.

• Verify that the SCSI Option ROM is enabled.

B. If your hard drives still do not show, please fill out the included customer support form and call

Intel Customer Support. Please pay special attention to the following information:

• What add-in adapters do you have in your system (manufacturer and part number)?

• What type of hard drives are in the system (manufacturer and part number)?

• What is the termination status of each hard drive? (drives inserted in the SC5000 hot

swap backplane are automatically terminated.)

• What are the SCSI ID’s of the devices on the SCSI bus?

• How many SCSI channels are you using?

11. My Hard Disk Drives don’t show up under Windows NT*

A. Verify that your hard disks are detected during POST (see Question 8). IDE drives will be

detected and listed on the screen by the server board BIOS and SCSI drives will be detected and

listed on the screen by the SCSI BIOS. It may be necessary to press the ESC key during POST to

remove the BIOS splash screen to view the POST diagnostics screen

B. Windows NT 4.0 does not ship with the latest drivers for the on-board Adaptec* AIC 7899 SCSI

controller used on the STL2 server board. Windows NT 4.0 must be directed to the proper SCSI

drivers manually. To do this, you must press F6 during installation startup at the sight of the first

“installation blue screen”, you will be prompted to manually install a driver. Use the driver

available on the CD that shipped with the server board or you can obtain the latest driver at:

<http://support.intel.com/support/motherboards/server/STL2. Additionally, you may need to manually load

the ATAPI* CD-ROM drivers, as applicable.

Intel Server Board Troubleshooting Guide -10-

C. If you still cannot see the on-board adapter or continue to have problems installing Windows NT,

please fill out the included customer support form and call Intel Customer Support. Please pay

special attention to the following information:

• Can you see the on-board Adaptec 7899 SCSI controller identify itself during POST?

• Can you see the drives getting logged during POST? (You should see the manufacturer’s

name and drive type during the Adaptec SCSI scan).

• Can you see other drives identify themselves during POST, such as IDE CDROMs, IDE

hard drives, etc.

• What is the termination status of each hard disk drive? (Drives in the SC5000 server

chassis SCSI hotswap backplane are automatically terminated.)
