WARNING

The total power requirement for the SRKA4 MP Server System exceeds the 240 VA energy hazard limit that defines an operator-accessible area. Only qualified service technicians should access the processor, memory, power subsystem, and non hot-plug/hot-swap areas of the SKA4 baseboard.

Peripherals

Peripheral Bay

The chassis contains one peripheral bay for CD-ROM, DAT, and floppy drives. The peripheral bay contains two smaller bays: a device bay and a configurable media bay.

Device Bay

The device bay accommodates either a 5.25-inch CD-ROM or a DAT drive. Only qualified service technicians should remove and install components in the device media bay.

14 SRKA4/ISP4400 Server System Product Guide

Page 15

Configurable Media Bay

The configurable media bay supports either one of the following configurations:

• A .5-inch slim line floppy drive and ½-inch slim line CD-ROM drive

• A 3.5-inch floppy drive

Only qualified service technicians should remove and install components in the configurable media bay.

Hard Drives

The chassis contains up to one hard drive bay. The hard drive bay supports either one of the following configurations:

• Five 3.5-inch by 1.0-inch hot-swap Adaptec Ultra 160/m SCSI SCA hard drives

• Three 3.5-inch by 1.6-inch hot-swap Adaptec Ultra 160/m SCSI SCA hard drives

Opening the front bezel door provides user access to the hard drives. As part of the hot-swap implementation, each hard drive requires a hard drive carrier. When you remove a hard drive from the system, you remove both the carrier and the hard drive. The drive is attached to the carrier by four screws. The carrier is locked into the hard drive bay by a locking handle. Figure 4 shows the orientation of the drive in the carrier. The carrier is upside down in this figure.

Figure 4. Hard Drive Secured in Drive Carrier

A. Hard drive carrier B. Two of four fasteners used to attach drive to carrier C. Hard drive D. Connector E. Locking handle

OM09937

Each hard drive is connected to an Adaptec Ultra/m 160 SCSI hot-swap backplane. The backplane provides industry-standard 80-pin SCA-2 connectors for each hard drive and accepts 10k or slower drives that consume up to 23 watts of power. If another type or slower Ultra 160 SCSI SCA drive is installed, make sure that the drive meets these backplane and carrier requirements.

✏ NOTE

All hard drives have different cooling, power, and vibration characteristics. Intel has validated specific hard drive types in the SRKA4 chassis. The SRKA4 Validation List contains a list of these manufacturers and hard drive types. The document can be found on

http://support.intel.com/support/motherboards/server/SRKA4/compat.htm

An LED above each hard drive displays the status of that hard drive.

LED State Status

Solid green The hard drive is present and powered on. Flashing green The hard drive is active. Solid yellow There is an asserted fault status on the hard drive. Flashing yellow A rebuild of the hard drive is in progress. Off The hard drive is not powered on.

Power Subsystem

The SRKA4 MP Server System uses a universal input-switching power subsystem (PSBS). This subsystem provides up to 630 Watts DC. The subsystem also minimizes the RMS current drawn from each AC line by providing power factor corrected AC input. The chassis can be configured with one, two, or three 350-Watt power supply modules, where each is designed to minimize electromagnetic interference (EMI) and radio frequency interference (RFI).

The power subsystem consists of a power subsystem bay, up to three power supply modules. The power subsystem bay contains a power distribution board, which manages the power delivered by all functional power supplies.

The power subsystem can operate in either a nonredundant or redundant way. Operating in a nonredundant way means that you are using only one or two power supply modules. If the power supply module ceases to function normally, the server system cannot function properly, if at all. A minimal configuration supported by one power supply module is one processor, four memory DIMMs, one hard drive that is not 10K, one floppy drive, and one CD-ROM.

The safer approach is to use a redundant (2+1) power subsystem. To form a (2+1) redundant power subsystem, the subsystem parallels the DC output of one power supply module with one or two other modules. If one module ceases to function normally, the remaining modules provide power to the server system and the system continues to function properly. Two power supply modules are required to provide power to a fully configured SRKA4 MP Server System. The third module provides redundancy. A fully configured system includes four processors, eight GB of memory, one floppy drive, one CD-ROM, five hard drives, and eight PCI add-in boards.

WARNING

16 SRKA4/ISP4400 Server System Product Guide

Page 17

System Cooling

The SRKA4 MP Server System uses up to six fans mounted in a fan board assembly in the middle of the chassis between the E-Bay and peripheral device bays. The six fans are noted by "A" in Figure 5.

OM09938

Figure 5. Fan Board Assembly with Six Fans

The SRKA4 server cooling system supports either a non-redundant configuration or a redundant configuration. A non-redundant configuration includes just three fans. If any one of these three fans ceases to function normally, environmental conditions within the chassis may exceed the environmental regulations in this guide and the chassis may not function normally. Three fans support any system configuration but without fan redundancy.

Operating the server with a non-redundant cooling system is not recommended for systems requiring high availability. To maintain SRKA4 MP Server System availability, Intel recommends the use of all six fans to form a redundant cooling system. If one of six fans ceases to function normally, the remaining five fans adequately cool the system. Using six fans supports any configuration up to the maximum configuration. Six fans support a maximum set of components. These components include four processors, 8 GB of SDRAM memory, five 10k hard drives, eight PCI add-in boards, and at least two power supply modules.

Air flows in through the front bezel over the power subsystem bay, the peripheral bay, and the hard drive bay. The air then passes through the fan board assembly and to the baseboard. Finally, the air exhausts through the rear and left side of the chassis.

Individual fan status indicators are located on the fan board mounted in the fan board assembly. Fan failure is also indicated by the general fault LED located at the front of the chassis.

WARNING

CAUTION

The top cover must be on the system for proper cooling.

4 Removing and Installing User Serviceable

Components

A user can remove and install two components. They are:

• Hot-swappable SCSI hard drives

• Hot-pluggable PCI add-in boards

The term hot-swap describes the process of removing and installing a system component WITHOUT shutting down the server. The term hot-plug describes the same process for PCI components only.

When removing and installing the hot-plug and hot-swap components described in this chapter, a user DOES NOT have to shut down the server.

WARNINGS

Hazardous conditions, power subsystem: Hazardous voltage, current, and energy levels are present inside the power subsystem. There are no user-serviceable parts inside it; servicing should be done by technically qualified personnel.

CAUTION

Electrostatic discharge (ESD) and ESD protection: ESD can damage hard drives, add-in boards, and other components. This server can withstand normal levels of environmental ESD while you are hot-swapping SCSI hard drives. However, Intel recommends doing all procedures in this manual only at an ESD-protected workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap attached to chassis

ground of the server—any unpainted metal surface—when handling components.

Page 26

SCSI Hard Drives

The system supports Adaptec Ultra 160/m SCSI SCA type or slower hard drives that are 3.5 inches wide. Contact a sales representative or dealer for a list of approved SCSI devices.

Mounting a SCSI Hard Drive in a Carrier

1. Remove the 3.5-inch wide hard drive from its wrapper and place it on an antistatic surface.

2. Record the drive model and serial number in your equipment log (page 91).

3. Remove the carrier filler panel and save the screws. You need them later in this procedure.

4. Orient the drive so the connector is near the top and rear of the drive carrier. Figure 8 shows

the orientation of the drive in the carrier. The carrier is upside down in this figure.

5. Using the screws from step 3 or other screws of the correct size and length (not supplied),

attach the carrier to the drive.

Removing a SCSI Hard Drive

A bank of five LEDs on the front of the hard drive bays monitors the drive status of each drive in the hot-docking bay. Each LED corresponds directly to a drive, so that the upper-most LED shows activity in the upper-most drive. The LEDs and corresponding drives are numbered (left to right) zero to four. When a yellow LED for a hard drive is on continuously, you are permitted to hot-swap (replace) a bad drive with a good one. If the operating system installed supports hot-swapping hard drives, the system DOES NOT need to be powered off.

WARNING

Peripherals

Peripheral Bay

The chassis contains one peripheral bay for CD-ROM, DAT, and floppy drives. The peripheral bay contains two smaller bays: a device bay and a configurable media bay.

Device Bay

The device bay accommodates either a 5.25-inch CD-ROM or a DAT drive. Intel strongly recommends NOT installing any device, such as a hard drive, requiring airflow cooling in the device bay. Installing such a device in this bay causes environmental conditions to exceed the cooling and electromagnetic interference (EMI) constraints of the system.

Configurable Media Bay

The configurable media bay supports either one of the following configurations:

• A .5-inch slim line floppy drive and .5-inch slim line CD-ROM drive

• A 3.5-inch floppy drive

Hard Drives

The chassis contains up to one hard drive bay. The hard drive bay supports either one of the following configurations:

• Five 3.5-inch by 1.0-inch hot-swap Adaptec Ultra 160/m SCSI SCA hard drives

• Three 3.5-inch by 1.6-inch hot-swap Adaptec Ultra 160/m SCSI SCA hard drives

OM09937

Figure 17. Hard Drive Secured in Drive Carrier

A. Hard drive carrier B. Four fasteners used to attach drive to carrier C. Hard drive D. Connector E. Locking handle

Each hard drive is connected to an Adaptec Ultra 160/m SCSI hot-swap backplane. The backplane provides industry-standard 80-pin SCA-2 connectors for each hard drive and accepts 10k or slower drives that consume up to 23 watts of power. If another type or slower Ultra 160/m SCSI SCA drive is installed, make sure that the drive meets these backplane and carrier requirements.

✏ NOTE

http://support.intel.com/support/motherboards/server/SRKA4/compat.htm

An LED above each hard drive displays the status of that hard drive.

LED State Status

The SCSI backplane boardset consists of two separate boards: the SCSI backplane board and the SCSI-Accessed Fault-Tolerant Enclosures Specification (SAF-TE) board. The SCSI backplane board provides power distribution and SCSI interfacing of the hard drives. The SAF-TE board provides SAF-TE features and hard drive failure indicators.

40 SRKA4/ISP4400 Server System Product Guide

Page 41

Power Subsystem

The SRKA4 MP Server System uses a universal input-switching power subsystem (PSBS). This subsystem provides up to 630 Watts DC. The subsystem also minimizes the RMS current drawn from each AC line by providing power factor corrected AC input. The chassis can be configured with one, two, or three 350-Watt power supply modules. Each module is designed to minimize electromagnetic interference (EMI) and radio frequency interference (RFI).

OM09947

Figure 18. Power Subsystem

The power subsystem consists of a power subsystem bay and up to three power supply modules. The power supply modules are noted by "A" in Figure 18. The power subsystem bay contains a power distribution board, which manages the power delivered by all functional power supplies.

The power subsystem can operate in either a nonredundant or redundant way. Operating in a nonredundant way means that you are using only one or two power supply modules. If the module ceases to function normally, the server system cannot function properly, if at all. A minimal configuration supported by one module is one processor, four memory DIMMs, one hard drive that is not 10K, one floppy drive, and one CD-ROM.

The safer approach is to use a redundant (2+1) power subsystem. To form a (2+1) redundant power subsystem, the subsystem parallels the DC output of one power supply module with one or two other modules. If one module ceases to function normally, the remaining modules provide power to the server system and the system continues to function properly. Two power supply modules are required to provide power to a fully configured SRKA4 MP Server System. The third module provides redundancy. A fully configured system includes four processors, sixteen gigabytes of memory, one floppy drive, one CD-ROM, five hard drives, and eight PCI add-in boards.

The SKA4 baseboard contains three embedded voltage converters: two 5 V input and one 12 V input. The baseboard also provides three connectors supporting 8.3-compliant, plug-in voltage regulator modules (VRM).

A Detailed Description of Chassis Features 41

Page 42

Each power subsystem auto-senses within the following voltage ranges and is rated as follows:

• 100-120 V∼ at 50/60 Hertz (Hz); 11.0 A maximum

• 200-240 V∼ at 50/60 Hz; 5.5 A maximum

The DC output voltages of each power supply module are:

• +3.3 V at 28 A max (Total combined power of the +3.3 and +5 channels must not exceed

195W)

• +5 V at 32 A max (Total combined power of the +3.3 and +5 channels must not exceed 195W)

• +12 V at 12.0 A with 15.0 A peak

• -12 V at 0.5 A

• +5 V standby at 2 A whenever AC power is supplied to the server system

The DC output voltages of the power subsystem with two or three modules are:

• +3.3 V at 50 A max (Total combined power of the +3.3 and +5 channels must not exceed

351W)

• +5 V at 58 A max (Total combined power of the +3.3 and +5 channels must not exceed 351W)

• +12 V at 22.0 A with 28.0 A peak

• -12 V at 0.5 A

• +5 V standby at 2 A

DC power is sourced through a 20-pin and 24-pin power cables to the baseboard. Remote sensing signals are provided through one 14-pin auxiliary power cable to the baseboard.

The AC power status of each power supply module is indicated by an LED. The LED is located on the power supply module.

LED State Status

Solid green AC power is applied to the pow er subsystem and standby voltage is available. Off The LED is off when one of the following conditions occur:

• The power supply modules are disabled by the DC enable signal.

• The power supply module is disabled by another switch.

• The power supply module has been overstressed.

• The power supply module has failed and replacement of the unit is necessary.

There are also three standby channels and each has an LED called a standby LED. These LEDs are located on the right side of the power subsystem bay and each indicates the status of that standby channel.

In a redundant configuration, individual power supply modules are hot-swappable. In other words, you can remove and install a power supply module without shutting down the server. After a power supply module has been removed from the system, airflow patterns are disrupted within the system. To maintain correct airflow patterns within the chassis and to ensure that all components remain within specification under all system environmental conditions, it is recommended that power supply module hot-swap operations do not exceed two minutes in duration.

42 SRKA4/ISP4400 Server System Product Guide

WARNING

System Cooling

The SRKA4 MP Server System uses up to six fans mounted in a fan board assembly in the middle of the chassis between the E-Bay and peripheral bays. The six fans are noted by "A" in Figure 19.

OM09938

Figure 19. Fan Board Assembly With Six Fans

Air flows in through the front bezel over the power subsystem bay, the peripheral bay, and the hard drive bay. The air then passes through the fan board assembly and the E-Bay. Finally, the air exhausts through the rear and left side of the chassis.

Individual fan status indicators are located on the fan board mounted in the fan board assembly. Fan failure is also indicated by the general fault LED located at the front of the chassis.

A Detailed Description of Chassis Features 43

Page 44

An LED above each cooling fan displays the status of that fan. The LEDs for two fans are noted by "A" in Figure 20. The LED on the left indicates the status of the fan pointed to by the left arrow. The LED on the right indicates the status of the fan pointed to by the right arrow.

Figure 20. Fan LEDs Indicating a Fan’s Status

LED State Status

Solid amber There is a fault with the cooling fan or the cooling fan is not present. Off The cooling fan is functioning properly.

OM09948

Individual fans are hot-swappable. In other words, you can remove and install a fan without shutting down the server. After a fan has been removed from the system, airflow patterns are disrupted within the system. The Baseboard Management Controller (BMC) firmware on the SKA4 baseboard polls the fans for status once every two minutes. Therefore, the BMC does NOT detect the removal and installation of an individual fan 3 seconds and two minutes. To maintain correct airflow patterns within the chassis and to ensure that all components remain within specification under all system environmental conditions, it is recommended that fan hot-swap operations do not exceed two minutes in duration.

CAUTION

The top cover must be on the system for proper cooling.

44 SRKA4/ISP4400 Server System Product Guide

Page 45

E-Bay

The E-Bay contains the SKA4 baseboard with the following components:

• Up to four Intel Pentium III Xeon processors. The SKA4 baseboard has four

SC330.1 connectors; each supports a processor. There are also four embedded Voltage Regulator Modules (VRM) and three VRM 8.3-compliant connectors to support up to four processors.

• The Server Set III HE chipset. This includes the HE North Bridge, Open South Bridge

(OSB4), and I/O.

• Up to sixteen PC/100-compliant Registered ECC SDRAM memory modules that support up to

16 gigabytes of Error Checking and Correcting (ECC) Synchronous Dynamic RAM.

• 32-bit, 33 MHz, 5V PCI segment with two expansion slots and three embedded devices.

• 64-bit, 66/33 MHz, 3.3V Hot-plug PCI segment with two expansion slots and one embedded

device.

• 64-bit, 33 MHz, 5V Hot-plug PCI segment with four expansion slots and three embedded

devices.

• Compatibility bus segment with three embedded devices.

• Two externally accessible and one internally accessible USB ports.

• One Adaptec AIC-7880 SCSI controller.

• One Adaptec AIC-7899 SCSI controller.

The Adaptec AIC-7899 SCSI controller has two channels called A and B. Channel A is connected to the HDD Backplane. Channel B is not connected to any device, but could be directed to the back of the system to an external SCSI device.

The Adaptec AIC-7880 SCSI controller supports both a Legacy Wide SCSI device and Legacy Narrow SCSI device. Both connections are not a standard part of the SRKA4 MP Server System. For a Legacy Wide or Narrow device, Intel provides two cables that can be routed to the peripheral bay on the front of the system. To purchase the cable, contact a sales representative. The Legacy Narrow connector can be routed to the peripheral bay.

The SRKA4 MP Server System supports up to sixteen memory modules totaling up to 15 gigabytes. However, only memory modules from a specific list of manufacturers are permitted. The SKA4 Memory Qualification List contains a list of these manufacturers and memory modules and can be found on

6 Removing and Installing System Components

Tools and Supplies Needed

• Phillips screwdriver (#1 and #2)

• Flat head screwdriver (#2)

• Jumper-removal tool or needle-nosed pliers

• Antistatic wrist strap and conductive foam pad (recommended)

• Pen or pencil

• Equipment log: As new parts are integrated into the system, add information about them to the

equipment log (page 91). Record the model and serial number of the system, all installed options, and any other pertinent information specific to the system. Some of this information may be required when running the SSU.

Safety: Before You Remove the Front and Top Covers

These warnings and cautions apply whenever you remove the top and front covers of the system. Only a technically qualified person should integrate and configure the system.

WARNINGS

CAUTIONS

Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives, boards, and other parts. Intel recommends that all procedures in this chapter are performed only at an ESD-protected workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap attached to chassis groundany unpainted metal surfaceon your system when handling parts.

Page 50

ESD and handling boards: Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only by their edges. After removing a board from its protective wrapper or from the system, place it component-side UP on a grounded, static-free surface. If you place the baseboard on a conductive surface, the battery leads may short out. If they do, this will result in a loss of CMOS data and will drain the battery. Use a conductive foam pad if available but NOT the board wrapper. Do not slide board over any surface.

Cooling and air flow: For proper cooling and airflow, always install the front cover before turning on the system. Operating the system without the top and front covers in place for an extended period of time can damage system parts.

Removal of the top cover for an extended period of time: If the SRKA4 MP Server System is turned on and has only three fans installed, make sure that you install the top cover within five minutes of removing it.

Removing and installing the SKA4 baseboard requires the removal and installation of baseboard components. Both procedures require this guide and the SKA4 Baseboard Product Guide. Before continuing, make sure that both product guides are readily available.

When this guide directs you to a procedure in the either the SRKA4/ISP4400 Server System Product Guide or the SKA4 Baseboard Product Guide, read the procedure first. You may have already completed steps in the procedure.

The baseboard resides in the E-Bay. The front, right, back, and left sides of the E-Bay are marked in Figure 16 on page 36.

Removing the Baseboard

CAUTIONS

The baseboard can be extremely sensitive to ESD and always requires careful handling. After removing it from the system, place it component-side UP on a nonconductive, static-free surface to prevent shorting out the battery leads. If you place the board on a conductive surface, the battery leads may short out. This will result in a loss of CMOS data and will drain the battery. Do not slide the baseboard over any surface.

Power Subsystem

The SRKA4 MP Server System can accommodate up to three power supply modules, each of which is enclosed in a power subsystem bay. The power subsystem bay contains a power distribution board (PDB). This board manages the power delivered by all functional power supply modules.

If all power supply modules are functioning and there is still a problem with powering on the server system, turn off the system by using the power on/off switch on the front panel AND unplug all AC power cords. Remove the power subsystem bay and send it back to an Intel customer service representative. Before sending the bay back, make sure all power supply modules are removed from the system.

WARNING

Hazardous conditions, power supply: Hazardous voltage, current, and energy levels are present inside the power subsystem. There are no user-serviceable parts inside it; servicing should be done by technically qualified personnel.

CAUTIONS

Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives, add-in boards, and other components. This server can withstand normal levels of environmental ESD while hot-swapping SCSI hard drives. However, Intel recommends doing all procedures in this manual only at an ESD-protected workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap attached to chassis ground of

the server—any unpainted metal surface—when handling components. Cooling and air flow: Once you remove a power supply, make sure you

replace it within two minutes. If not possible in this timeframe, re-insert the original unit. When a replacement unit is available, repeat the replacement procedure. Vacant spaces alter airflow patterns in the server system and may cause environmental conditions to exceed the environmental limits of the server.

Removing a Power Supply Module

1. Remove the front bezel by gently pulling on the edge of the front bezel. The ball studs of the

bezel release. One of four ball studs is noted by "A" in Figure 28.

OM09954

Drive Cabling Considera tions

This section summarizes device cabling requirements and constraints. The number of devices that can be installed depends on:

• The number supported by the bus

• The number of physical drive bays available

• The height of drives in the internal bays (1-inch or 1.6-inch high)

• The combination of SCSI and IDE devices

SCSI Requirements

All SCSI devices must not be terminated except the peripheral at the end of the SCSI cable. Hard drives usually provide an active termination, while CD-ROM drives do not. Because Intel recommends putting hard drives only in the internal bays, the SCSI cable should be routed so that the last device on the cable is a hard drive in the internal bay.

NOTE

✏

Integrating the 5.25-inch peripheral bay can affect EMC compliance and is a regulated activity. Except as noted here, any changes to the bay configuration could result in noncompliance with EMC regulations.

CAUTION

To avoid damage to a 5.25-inch peripheral device, ensure the EMI gasketing provided in the device bay does not bridge any open circuits on the exposed peripheral device.

7 Solving Problems

This chapter helps you identify and solve problems that might occur while you are using the system.

Resetting the System

To do this: Press:

Clear system memo ry, restart POST, and reload the operating system. Reset button or

<Ctrl+Alt+Del>

Cold boot reset, which clears system memory, rest arts POST, reloads the operating system, and halts power to all peripherals.

Initial System Startup

Problems that occur at initial system startup are usually caused by incorrect installation or configuration. Hardware failure is a less frequent cause.

Initial System Startup Checklist

q Are all cables correctly connected and secured? q Are the processors fully seated in their slots on the baseboard? q Are all PCI add-in boards fully seated in their slots on the baseboard? q Are all switch and jumper settings on the baseboard correct? q Are all jumper and switch settings on add-in boards and peripheral devices correct? To check

these settings, refer to the manufacturer’s documentation that comes with them. If applicable, ensure that there are no conflicts—for example, two add-in boards sharing the same interrupt.

q Are all DIMMs installed correctly? q Are all peripheral devices installed correctly? q If the system has a hard drive, is it properly formatted or configured? q Are all device drivers properly installed? q Are the configuration settings made with the SSU correct? q Is the operating system properly loaded? Refer to the operating system documentation. q Did you press the system power on/off switch on the front panel to turn the server on

(power-on light should be lit)?

q Are the system power cords properly connected to the system and plugged into a NEMA

6-15R outlet for 100-120 V∼ or for 200-240 V∼?

q Is AC power available at the wall outlet? q If these items are correct but the problem recurs, see "Specific Problems and Corrective

Actions" on page 73.

Power off/on

Page 72

Running New Application Software

Problems that occur when you run new application software are usually related to the software. Faulty equipment is much less likely, especially if other software runs correctly.

Application Software Checklist

q Does the system meet the minimum hardware requirements for the software? See the software

documentation.

q Is the software an authorized copy? If not, get one; unauthorized copies often do not work. q If you are running the software from a diskette, is it a good copy? q If you are running the software from a CD-ROM disk, is the disk scratched or dirty? q If you are running the software from a hard drive, is the software correctly installed? Were all

necessary procedures followed and files installed?

q Are the correct device drivers installed? q Is the software correctly configured for the system? q Are you using the software correctly? q If the problems persist, contact the software vendor’s customer service representative.

After the System Has Been Running Correctly

Problems that occur after the system hardware and software have been running correctly often indicate equipment failure. Many situations that are easy to correct, however, can also cause such problems; sometimes the problem stems from changes made to the system, such as hardware or software that has been added or removed.

System Checklist

q If you are running the software from a diskette, try a new copy of the software. q If you are running the software from a CD-ROM disk, try a different disk to see if the problem

occurs on all disks.

q If you are running the software from a hard drive, try running it from a diskette. If the

software runs correctly, there may be a problem with the copy on the hard drive. Reinstall the software on the hard disk, and try running it again. Make sure all necessary files are installed.

q If the problems are intermittent, there may be a loose cable, dirt in the keyboard (if keyboard

input is incorrect), a marginal power supply, or other random component failures.

q If you suspect that a transient voltage spike, power outage, or brownout might have occurred,

reload the software and try running it again. (Symptoms of voltage spikes include a flickering video display, unexpected system reboots, and the system not responding to user commands.)

NOTE

Power Light Does Not Light

Check the following: q Are all the power supplies plugged in? Is the power turned on to the power strip or outlet? Do

you have a blown fuse or breaker?

q Is the system functioning normally? If so, the power LED may be defective, the cable from

the front panel to the fan board is loose, or the cable from the fan board to the baseboard is loose.

q Are there other problems with the system? If so, check the items listed under “System Cooling

Fans Do Not Rotate Properly.”

If all items are correct and problems persist, contact your service representative or authorized dealer for assistance.

No Beep Codes

If the system operates normally, but there was no beep, the speaker may be defective. If the speaker is enabled, but the speaker does not function, contact your service representative or authorized dealer for assistance.

Record the beep code emitted by POST, and see “Error and Informational Messages” on page 77.

No Characters Appear on Screen

Check the following:

q Is the keyboard working? Check to see that the “Num Lock” light is functioning. q Is the video monitor plugged in and turned on? Many modern video monitors shut down when

inactive and may require a moment to warm up when activated.

q Are the brightness and contrast controls on the video monitor properly adjusted?

Solving Problems 73

Page 74

q Are the video monitor switch settings correct? q Is the video monitor signal cable properly installed? q Is the onboard video controller enabled?

If you are using an add-in video controller board, do the following:

1. Verify that the video controller board is fully seated in the baseboard connector (and verify

that the video monitor is plugged in to the ACTIVE video controller).

2. Reboot the system for changes to take effect.

3. If there are still no characters on the screen after you reboot the system and POST emits a beep

code, write down the beep code you hear. This information is useful for your service

representative. See “POST Codes and Countdown Codes” on page 77.

4. If you do not receive a beep code and characters do not appear, the video display monitor or

video controller may have failed. You can verify this by trying the monitor on another system or trying a different monitor on this system. Contact your service representative or authorized dealer for assistance.

Characters Are Distorted or Incorrect

Check the following: q Are the brightness and contrast controls properly adjusted on the video monitor? See the

manufacturer’s documentation.

q Are the video monitor signal and power cables properly installed? q Is the correct monitor/video board installed for your operating system?

If the problem persists, the video monitor may be faulty or it may be the incorrect type. Contact your service representative or authorized dealer for assistance.

System Cooling Fans Do Not Rot ate Properly

If the system cooling fans are not operating properly, system components could be damaged. Check the following:

q Is AC power available at the wall outlet? q Are the system power cords properly connected to the system and the wall outlet? q Did you press the power on/off push-button switch? q Is the power-on light lit? q Have any of the fan motors stopped (use the server management subsystem to check the fan

status)?

q Is the cable from the fan board connected to the baseboard? q Are the power supply cables properly connected to the baseboard and the fan board assembly? q Are there any shorted wires caused by pinched cables or power connector plugs forced into

power connector sockets the wrong way?

If the switches and connections are correct and AC power is available at the wall outlet, contact your service representative or authorized dealer for assistance.

Diskette Drive Activity Light Does Not Light

Check the following:

q Are the diskette drive power and signal cables properly installed? q Are all relevant switches and jumpers on the diskette drive set correctly? q Is the diskette drive properly configured? q Is the diskette drive activity light always on? If so, the signal cable may be plugged in

incorrectly.

If you are using the onboard diskette controller, use the SSU to make sure that “Onboard Floppy” is set to “Enabled.” If you are using an add-in diskette controller, make sure that “Onboard Floppy” is set to “Disabled.” To run the SSU, see the SKA4 Baseboard Product Guide.

If the problem persists, there may be a problem with the diskette drive, baseboard, or drive signal cable. Contact your service representative or authorized dealer for assistance.

Hard drive Activity Light Does Not Light

If you have installed one or more hard drives in your system, check the following:

q Are the power and signal cables to the drive properly installed? q Are all relevant switches and jumpers on the hard drive and adapter board set correctly? q Is the hard drive properly configured?

NOTE

✏

Front panel hard disk LED indicates SCSI devices: The hard drive activity light on the front panel lights when a SCSI device controlled by the onboard SCSI host controller is in use. This LED does not display CD-ROM activity.

CD-ROM Drive Activity Light Does Not Light

Check the following:

q Are the power and signal cables to the CD-ROM drive properly installed? q Are all relevant switches and jumpers on the drive set correctly? q Is the drive properly configured? q Is the onboard IDE controller enabled?

Network Problems

The server hangs when the drivers are loaded.

q Change the PCI interrupt settings. Try the “PCI Installation Tips” below.

Diagnostics pass, but the connection fails.

q Make sure the network cable is securely attached. q Make sure you specify the correct frame type in your NET.CFG file.

The Link LED does not light.

q Make sure you have loaded the network drivers. q Check all cable connections. q Try another port on the hub. q Make sure you have the correct type of cable between the adapter and the hub. Some hubs

require a crossover cable while others require a straight through cable. For more information on crossover cabling, see your hub documentation.

The Activity LED doesn’t light.

q Make sure you’ve loaded the correct network drivers. q Network may be idle. Try accessing a server.

The controller stopped working when an add-in adapter was installed.

q Make sure the cable is connected to the port from the onboard network controller. q Make sure your PCI BIOS is current. Try the “PCI Installation Tips” below. q Make sure the other adapter supports shared interrupts. Also, make sure your operating system

supports shared interrupts; OS/2 does not.

q Try reseating the add-in adapter.

The add-in adapter stopped working without apparent cause.

q Try reseating the adapter first; then try a different slot if necessary. q The network driver files may be corrupt or deleted. Delete and then reinstall the drivers. q Run the diagnostics.

PCI Installation Tips

Some common PCI tips are listed here. q Certain drivers may require interrupts that are not shared with other PCI drivers. The SSU can

be used to adjust the interrupt numbers for PCI devices. For certain drivers, it may be necessary to alter settings so that interrupts are not shared.

q Check PCI interrupt interdependencies among slots and onboard devices.

Problems with Application Softwar e

If you have problems with application software, do the following: q Verify that the software is properly configured for the system. See the software installation

and operation documentation for instructions on setting up and using the software.

q Try a different copy of the software to see if the problem is with the copy you are using. q Make sure all cables are installed correctly.

76 SRKA4/ISP4400 Server System Product Guide

Page 77

q Verify that the baseboard jumpers are set correctly. See the SKA4 Baseboard Product Guide

for more information.

q If other software runs correctly on the system, contact your vendor about the failing software.

If the problem persists, contact the software vendor’s customer service representative for assistance.

Bootable CD-ROM Is Not Detected

Check the following: q Is the BIOS set to allow the CD-ROM to be the first bootable device?

Error and Informational Messages

When you turn on the system, POST displays messages that provide information about the system. If a failure occurs, POST emits beep codes that indicate errors in hardware, software, or firmware. If POST can display a message on the video display screen, it causes the speaker to beep twice as the message appears.

WARNING: English (US)

The power supply in this product contains no user-serviceable parts. There may be more than one supply in this product. Refer servicing only to qualified personnel.

Do not attempt to modify or use the supplied AC power cord if it is not the exact type required.

The DC push-button on/off switch on the system does not turn off system AC power. To remove AC power from the system, you must unplug each AC power cord from the wall outlet or power supply.

SAFETY STEPS: Whenever you remove the top and front covers in a non hot-swap or non hot-plug operation, follow these steps:

1. Turn off all peripheral devices connected to the system.

2. Turn off the system b y using the push-button on/of f power switch on the system.

3. Unplug the AC power cord from the system or from wall outlets.

4. Label and disconnect all cables connected to I/O connectors or ports on the back of the system.

5. Provide some electrostatic discharge (ESD) protection by wearing an antistatic wrist

strap attached to chassis ground of the system—any unpainted metal surface—when handling components.

6. Do not operate the system with the covers removed.

The system has two covers: a top cover and a front cover. After you have completed the six SAFETY steps above, any user can remove the top cover.

However, only qualified service personnel can remove the front cover.

For proper cooling and airflow, always reinstall the chassis covers before turning on the system. Operating the system without the covers in place can damage system parts. To install t he covers:

1. Check first to make sure you have not left loose tools or parts inside the system.

2. Check that cables, add-in boards, and other components are properly installed.

3. Attach the covers to the chassis with the screws removed earlier, and tighten them firmly.

4. Connect all external cables and the AC power cord to the system.
