SBP-205 Installation

The MaxPro tower server or ProRack rackmount system has been fully set up by
CSS Laboratories before delivery. The passive backplane and single board
computer(s) have been installed and configured at the factory.

Typically, no single board computer (SBC) installation is necessary. However, the
modular design of the MaxPro and ProRack systems enables you to customize them
to meet specific needs. Swapping out the single board computer(s) is one way the
MaxPro and ProRack systems can be customized and upgraded.

Overview

The SBP-205 connects to any CSS Laboratories passive backplane through one
EISA connector with a PCI bus extension. This SBC connector socket combination
is located on the passive backplane.

Installing the SBP-205 to a Passive Backplane

7. Close the system case and reconnect the external cables.

Jumper Switches

The SBP-205 jumper switches are pre-configured at the factory. Jumpers are used to
configure the processor bus frequency and to clear CMOS contents.

Jumper Switches Overview

The Pentium III processor uses a clock multiplier to match the processor core
frequency with the speed of the processor bus—the speed at which data travels into
and out of the processor. Four jumper switches determine the processor bus
frequency. Another jumper temporarily clears the CMOS contents.

• CSS Laboratories Section 2 – Using the SBP-205 • 14

•

NOTE: With the new Pentium III processor, it is not necessary to set jumper

switches to determine the bus processor frequency. The Pentium III processor is self­adjusting.

Two-pin jumpers are described as jumped, “on” or “in” with the small plastic jumper
cap on, or not jumped, “off” or “out” with the jumper cap off.

Jumpers with more than two pins are described by numbering the pins. Each of the
SBP-205 jumpers has the number “1” stamped on the board next to that jumper’s pin
number one.

The jumper cap placed over a particular combination of pins, such as 1-2 or 2-3,
determines the jumper setting.

Setting Jumper Switches

Setting jumper switches is easiest with the SBP-205 removed from the system. While
the jumper switches are accessible with the SBP-205 installed, it might be necessary
to remove one or more adapter cards if they restrict access to the jumpers.

To access the jumper switches:

1. Power down the system and remove the power cord and any other
external connectors.

2. Open the system case.

Follow the instructions in the MaxPro or ProRack User Guide that

accompanied your system.

3. Locate the jumper switches you wish to set.

4. Temporarily remove any adapters or connectors that restrict your
access to the jumper switches.

5. If necessary, temporarily remove the SBP-205 from the system.

For SBP-205 removal and installation procedures, see Installing the

SBP-205 to a Passive Backplane.

To temporarily clear the CMOS:

CMOS contains the system BIOS configurations. Temporarily placing a jumper cap
on JP17 pins 2-3 clears the contents of the CMOS chip.

To set CPU clock speed::

The Pentium III processor automatically adjusts processor speed ratios. There is no
need to reset jumper switches to match the bus speed and the processor clock speed.

With a Pentium II processor, jumper settings are used to multiply the bus speed to
match the processor clock speed. The SBP-205 provides a chart stamped on the
board which gives the processor speed ratios at different settings of jumper JP7.

BIOS Configuration

BIOS Configuration Overview

The SBP-205 features an AMI BIOS with built-in CMOS setup for system
parameters, peripheral management and PCI bridge and interrupt steering.

The MaxPro tower servers and ProRack rackmount systems with the SBP-205
installed automatically detect and configure PCI-compliant adapters while booting.
The BIOS automatically sets the adapter IRQ levels and I/O addresses each time the
computer starts.

Resource configuration is complete when the operating system starts. If the system
displays an error while booting, it may require additional steps to configure.

Access the BIOS setup by pressing the [Delete] key after the POST memory test
begins and before the operating system boot begins.

Section 3 – Maintenance and
Troubleshooting

Routine Maintenance

Follow these basic steps to maintain and safeguard the SBP-205 single board
computer:

 The MaxPro tower server chassis and the ProRack rackmount chassis are

designed to provide protection for internal devices and connections. Care must
still be taken to ensure that the system case won’t be kicked or struck. An impact
could damage disk drives.

 Do not place the MaxPro or the ProRack near any heat source that may damage

it, such as heaters, direct sunlight, etc.

 Do not eat, drink or smoke near the system.

Troubleshooting

 Use a surge protector with the MaxPro or ProRack and any peripheral devices.

Power surges can damage or destroy the SBP-205 or other components. Surges
can also destroy data on the hard drives.

 Allow a space of at least eight inches around your system for proper ventilation.

 Do not plug the MaxPro or ProRack into the same electrical circuit with a

“noisy” electric motor, such as a blender or a vacuum cleaner.

 Ground yourself by touching the system case before touching any hardware or

software. This discharges the static electricity in your body. (Static electricity
can damage components).

 Keep the system clean and free of dust. Use commercially available dust covers.

Troubleshooting Tools

The first and most important sign of trouble is that a particular device simply is not
working. The other main indicator is that you receive error messages, either on
power up or when attempting to use a particular device.

The SBP-205 functions only in conjunction with other components, including a
passive backplane and optional adapter cards. Most problems with the SBP-205 will
be traceable to connections or to software including the BIOS.

Several common physical problems and problems with related devices are discussed
in this section and in the Troubleshooting Using System Utilities topic later in this
section.

There are three main troubleshooting tools:

1. Direct inspection

2. Troubleshooting using system utilities

• CSS Laboratories Section 3 – Maintenance and Troubleshooting • 23

•

The various Windows operating systems, for example, provide system

information, data on problem devices and other troubleshooting
utilities.

3. Troubleshooting Tables

These tables deal with problems and solutions that are primarily

physical in nature, but can also involve reconfiguring software
installations. The Troubleshooting Tables build upon and work with
what you learn by doing the initial inspection steps. Use all three tools
together as necessary.

Troubleshooting by Direct Inspection

First, make sure that the power cord(s) and all external connectors are properly
connected. Then make sure that the system itself and its peripherals are turned on,
particularly any peripheral that isn’t working.

Next, answer this question: Have you installed any new hardware or software since
the system was last working properly? If you have just added any new hardware or
software, then remove the software or device and see if the system now runs
correctly. If it does, reinstall the new device and/or software. Reinstalling often
resolves hardware conflicts and solves the problem.

Troubleshooting Using System Utilities

Different operating systems provide different arrays of troubleshooting and system
utilities. The steps outlined here provide an example of using the Windows NT
system utilities to pinpoint problem devices.

1. Access the Control Panel from the Start Menu or from the Windows
desktop.

2. Double-click the Devices icon. This will display the Devices window.

Figure 14—Windows NT Devices Window

3. Select the problem device and click the HW Profiles button. This will
display the Device window.

4. Click the Enable button if the device is incorrectly disabled.

• CSS Laboratories Section 3 – Maintenance and Troubleshooting • 24

•

Figure 15—Windows NT Device Window

5. Click the Disable button if the device is enabled and is still not
functioning properly.

6. Adjust the resource settings as necessary using the BIOS setup utility.

The resource settings include the IRQ and the I/O address currently in use by the
device. This often is where a device problem can occur, as the IRQ or the I/O
address settings can be the same as those for another device on the system.

If there is a device conflict, reinstalling the software drivers will usually reassign
IRQs and I/O addresses and often will resolve the conflict and the problem.

Windows NT does not provide direct control of device resource allocations or
hardware conflict information. Individual devices must be installed using the BIOS
utilities. See BIOS Configuration for more information.

Windows 2000 addresses this deficiency, and provides more detailed system
information and greater device installation control from within the operating system.

Troubleshooting Tables

The following tables list common problems and the basic handlings to resolve those
problems. The handlings are only the most likely steps to take, suggested guidelines.
Use them in conjunction with the direct inspection and system utilities tools
discussed earlier.

• CSS Laboratories Section 3 – Maintenance and Troubleshooting • 25

SBP-205 Troubleshooting Tables

GENERAL PROBLEMS HANDLING

The system will not power on. 1. Make sure that the power cables are properly

connected.

2. Make sure that all power strips, UPS and power
outlets have power.

3. If you’ve just installed a new optional device, remove
it and reboot the system.

4. Make sure that all power switches on the MaxPro or
ProRack hot swappable power supplies are in the On
position.

If the problem persists, have the system serviced.

Damaged switches, broken indicator lights, etc. Have the system serviced and the broken or damaged parts

replaced.

Other power problems or intermittent power errors. 1. Make sure that all external power connectors are

properly seated and that the system power switches
are on, including the front panel switch, auxiliary
switches and individual power supply switches.

2. Make sure that the current selector switches on the
power supplies are set to the proper current (110v or
220v).

3. If this does not resolve the problem, inspect the P1
and P2 power connector on the passive backplane.
Also inspect the other power connectors such as the
Auxiliary P1 and P2 connectors and terminal lugs if
they are in use. Make sure that all connectors are
properly seated at both ends and that there are no
breaks in the wires.

If the problem persists, inspect the on-board connectors for
damaged pins. If any pins are damaged, have the system
serviced.

CMOS (system) clock errors. 1. Inspect the lithium 3.3 volt (BAT) connector on the

passive backplane. Make sure that the connector is
properly seated at both ends.

2. If the problem persists, inspect the battery located on
the SBP-205. Make sure that it is properly seated or
replace the battery.

3. If the problem persists, inspect the BAT connector on
the passive backplane for damaged pins. If any pins
are damaged, have the system serviced.

Reset button does not reset the system. 1. Inspect the reset/turbo (RST) connector on the passive

backplane. Make sure that the connector is properly
seated at both ends.

2. If the problem persists, inspect the RST connector on
the passive backplane for any damaged pins. If any
pins are damaged, have the system serviced.

If the problem persists, have the system serviced.

• CSS Laboratories Section 3 – Maintenance and Troubleshooting • 26

•

INPUT DEVICE PROBLEMS HANDLING

Some or all of the keyboard keys don’t work. 1. Make sure that the keyboard is properly connected to

the system, and make sure that the system and the
monitor are turned on.

2. Test if the problem is with the keyboard or something
else by swapping out the keyboard with one from
another system.

3. If the problem lies with the keyboard itself, have it
serviced or replaced.

The mouse doesn’t work. 1. Make sure that the mouse is correctly connected to the

system. If so, use the Inspection steps outlined above
to determine if the mouse drivers are properly
installed and not in conflict with any other drivers.

2. If the problem persists, replace the mouse.

MONITOR PROBLEMS HANDLING

The screen is blank. 1. Make sure that the screen has not been blanked by

power management settings. If so, moving the mouse
or touching a key will bring the monitor back to active
mode.

2. Make sure that the monitor power cord is plugged into
a working electrical outlet.

3. Make sure that the monitor itself is turned on and that
the contrast and brightness are properly adjusted.

4. Make sure that the monitor cable is properly
connected to the system unit.

5. If these steps don’t resolve the problem, have the
monitor serviced or replaced.

The monitor screen is out of synchronization 1. Reduce the resolution of the video display adapter.

Consult the operating system and/or video display
adapter user guides for procedures.

2. Reduce the refresh rate. Consult the operating system
and/or video display adapter user guides for
procedures.

The screen flickers some or all of the time. Use the monitor software utilities (see your monitor user

manual) to set it for the highest possible refresh rate.

If the problem persists, have the monitor serviced or
replaced.

Distortion or some other kind of screen jitter, wavy image
or rolling image.

• CSS Laboratories Section 3 – Maintenance and Troubleshooting • 27

Check all monitor connections and any self-tests described
in your monitor’s user manuals. If the monitor checks out
OK, inspect the monitor’s location. Is it near some other
electromagnetic device such as an appliance, electrical
transformer, fluorescent lights, etc?

If so, turn off the monitor and either move it or the other
device a minimum of a foot apart. Turn the monitor back
on. If the problem still persists, have the monitor serviced
or replaced.

•

MEMORY PROBLEMS HANDLING

The amount of memory displayed by the operating system
is less than the memory installed.

1. Make sure that the DIMMs are properly installed and
seated in their slots. You’ll have to open the system
case to do this. See Installing and Removing Memory
for information and procedures.

2. Make sure that the installed memory is the correct
type for the system, or if you have more than one
memory module installed, that all modules are
compatible. See Memory Guidelines for more
information.

If this is all correct, the operating system provides an array
of troubleshooters and diagnostics to help you identify the
problem. In Windows operating systems, this utility can be
accessed through Windows Help.

PORT OR PERIPHERAL DEVICE PROBLEMS HANDLING

The parallel port doesn’t work or isn’t recognized by the
system.

1. The parallel port is mounted on the SBP-205. Check
the BIOS setting to see if it has been disabled.

2. Open the system case and make sure that the parallel
port data cable and power connector are properly
seated in their slots on the SBP-205. Refer to
Connectors to make sure it’s in the right slot.

3. Use the system utilities troubleshooting steps to make
sure that the port has a unique I/O address and that it
is not in conflict with any other devices.

If the problem persists, have the system serviced.

The number of serial and parallel ports displayed is less
than the number installed.

A serial or parallel device doesn’t work. This includes
printers and any other devices that connect to serial or
parallel ports.

1. Make sure that the port has not been disabled in the
BIOS CMOS.

2. Use the system utilities to make sure that each port has
a unique I/O address and that none are in conflict with
any other devices.

3. Make sure that the internal port connectors are
properly seated in the proper slot on the SBP-205.
Refer to Connectors to make sure each is connected to
the correct slot.

If the problem persists, have the system serviced.

Make sure that the ports are functioning, as in the above
section of this table. Make sure that the device is properly
connected to the port, is turned on, and that the driver(s)
are properly installed.

If the problem persists, and the ports are functioning
properly, have the device serviced or replaced.

• CSS Laboratories Section 3 – Maintenance and Troubleshooting • 28

•

PORT OR PERIPHERAL DEVICE PROBLEMS HANDLING

The system does not recognize an installed PCI or ISA
adapter.

1. Make sure that any external connections to the adapter
are properly connected.

2. Ensure that any software applications or drivers for
the PCI or ISA adapter have been installed correctly.
Consult the manual that came with the adapter for
specific troubleshooting steps.

3. If the problem persists, inspect the PCI or ISA
adapter. Make sure that it is properly seated into the
PCI or ISA slot. If any additional connectors are
required, make sure that they are properly seated.

4. If the problem persists, try installing the adapter to a
different slot.

If the problem persists and there are no other system
problems, have the adapter serviced or replaced.

DISKETTE DRIVE PROBLEMS HANDLING

The diskette drive isn’t working: the in-use light stays on,
or the system doesn’t recognize the drive at all.

Ensure that there is a diskette properly inserted in the
drive. If so, then make sure that the diskette itself is
properly formatted and isn’t damaged. Damage doesn’t
have to be evident to the naked eye—such as a cracked
casing. The diskette or the data on it could have been
damaged through becoming magnetized.

Make sure the floppy cable is connected correctly. The
floppy light will stay on if the cable is reversed.

If the diskette is okay, make sure it contains the proper
files to do what you want it to do (in the case of a software
installation or program diskette).

If the problem persists, have the system serviced. The
drive itself might be improperly connected or
malfunctioning.

• CSS Laboratories Section 3 – Maintenance and Troubleshooting • 29

•

HARD DRIVE PROBLEMS HANDLING

A frontloading swappable hard drive doesn’t work or data
on the drive isn’t detected by the system or a flashing
green LED indicates a problem.

1. Gently press on the front of the drive tray to make
sure that the tray connectors are properly seated and
that the tray face is flush with the MaxPro or ProRack
system case.

2. If the drive still does not work, unlock the keylock and
remove the drive tray. Make sure that the power
connector and the controller connector are properly
connected to the drive. Return the drive tray to
operating position. Make sure it is properly seated and
lock the keylock.

3. If there is more than one tray, try swapping with
another one to see if it can be recognized by the
controller card. Do not swap the position of a drive in
a RAID Array. (It is position sensitive).

If the drive still does not work, have the drive serviced or
replaced.

Other hard drive data access problems. Consult the SCSI documentation for termination

information and procedures. All SCSI devices must be
properly terminated. CSS Laboratories terminates the last
SCSI cable end with an active terminator.

If none of the above solutions resolve data access or other
system operation problems related to the hard drive, see
the operating system user guides for diagnostic and repair
tools.

CD-ROM DRIVE PROBLEMS HANDLING

The CD-ROM doesn’t work or data on the CD isn’t
detected by the system.

Clean the CD-ROM with a clean, lint-free cloth using a
motion outward from the center, NOT in a circle. (This can
damage the data on the disk).

If this doesn’t solve the problem, clean the optical head
lens. Lens cleaning kits are commercially available.

Make sure that the CMOS and SCSI settings are enable for
the CD.

If this still doesn’t solve the problem, have the CD-ROM
serviced or replaced.

The CD-ROM disk tray doesn’t work. Make sure that the system power is turned on. The tray

won’t open and close without it.

To open a tray that is stuck closed, gently insert the tip of a
paperclip into the manual tray release (a small hole to the
right of the tray release button.) Press gently to open the
tray. This will often free it.

If the tray still doesn’t work, have the drive serviced or
replaced.

• CSS Laboratories Section 3 – Maintenance and Troubleshooting • 30

•

CD-ROM DRIVE PROBLEMS HANDLING

The system doesn’t recognize the CD-ROM drive. Check for missing or improperly installed software drivers.

If the correct drivers are properly installed, open the
system case and ensure that the CD-ROM power connector
and controller connector are properly connected at both
ends.

SOFTWARE PROBLEMS HANDLING

A software program doesn’t work: it terminates, gives
error messages, causes problems with other software
applications, etc.

Make sure that the problems are caused by the software
itself by answering some questions:

 Does the system have the memory required to run the

software? Refer to the program manual for memory
requirements.

 Is the memory properly installed and configured?
 Is the software designed to run on your system?

 Does other software work on your system?

 Does the software work on another system?

Refer to the software manual for the meaning and handling
of any error messages to help narrow down the problem.

If the software is not the problem, then trace down the
various system devices that the software uses. Apply the
troubleshooting steps outlined in these tables and earlier in
this topic to ensure that those devices are properly
connected and working.

DMI

Desktop Management Interface. A system for managing the configurations and status
of PCs on a network from a central computer.

Driver

A special program that controls a device such as a mouse, CD-ROM or modem.

ECC

Error-Correcting Code. A code designed for transmission of electronic data so that
transmission errors may be detected and corrected at the receiving end.

EDO

Extended Data Out. A type of dynamic random access memory (DRAM) that allows
for faster read times than DRAM of comparable speed by allowing a new read cycle
to begin while data is being read from a previous cycle.

EIDE

Stands for Enhanced Integrated Drive Electronics. An extension of the IDE standard,
Enhanced IDE is a hardware interface standard for disk drive designs that house
control circuits in the drives themselves. It allows for standardized interfaces to the
system bus while providing for advanced features, such as burst data transfer and
direct data access. Enhanced IDE accommodates drives as large as 8.4 gigabytes
(IDE supports up to 528 megabytes). See also IDE, SCSI.

Ethernet

A local area network (LAN) standard that uses coaxial or twisted pair cable.

Hard Drive

A magnetically coated metal disk sealed in a box, used to store large quantities of
data.

I/O address

Input/Output address. The place in computer memory where data from devices is
read or written.

IDE

Integrated Drive Electronics or Intelligent Device Electronics. A type of interface for
controlling hard disk drives.

IRQ

Interrupt ReQuest. Used to let the computer know that a device is ready to do
something or that it has done something.

ISA

Industry Standard Architecture. A bus design that allows components to be added as
cards plugged into computer expansion slots.

Jumper

A pair of prongs that are electrical contact points set into a computer motherboard or
an adapter card. A small plastic plug placed on the prongs completes a contact in
order to alter an aspect of the computer configuration. A group of jumpers is called a
jumper block.

LAN

Local Area Network. A group of computers and other devices dispersed over a
relatively limited area and connected by a communications link that enables any
device to interact with any other on the network.

LED

Light Emitting Diode. A device that emits light when electricity passes through it.

LUN

Stands for Logical device or drive Unit Number. A device named by the logic of a
software system, regardless of its physical relationship to the system.

Menu

A list of options from which a user can make a selection in order to perform a
desired action.

MIS

Management Information Systems. Usually a department within a company that is
responsible for running and repairing computers and software.

Motherboard

The main circuit board of a computer to which most other devices connect. A single
board computer combined with a passive backplane form one complete motherboard
with extended processing, power and device connection capabilities.

Parallel

The transmission of data eight or more at a time; a type of device, such as a “parallel
port” that sends or receives data in this fashion. See also: Serial.

Passive Backplane

See Backplane.

PCI

Peripheral Component Interconnect A computer industry standard bus. See
also: Bus.

Peripheral

External equipment or devices connected to the computer. Examples include
monitor, printer, scanner, mouse and speakers.

Port

A jack in the back of the computer into which you can plug a peripheral device.

POST

Power On Self Test. This is the battery of tests the computer runs on itself when it
starts.

P/S2

A bus designed with Micro Channel Architecture as found in most IBM PS/2
computers. The Micro Channel functions as either a 16-bit or a 32-bit bus. The P/S2
bus can be driven independently by multiple bus master processors.

RAID

Stands for Redundant Array Of Independent Disks. A data storage method in which
data, along with information used for error correction is distributed among two or
more hard disk drives in order to improve performance and reliability. The hard disk
array is governed by array management software and a disk controller, which
handles the error correction. RAID is generally used on network servers.

RAM

Random Access Memory. The internal memory of the computer, stored on chips
installed on the Motherboard.

Reboot

To restart the computer. A “warm reboot” is done by pressing a reset switch. A
“cold reboot” is done by turning the machine off and then on again.

SCSI

Small Computer System Interface, often pronounced “skuzzy.” An industry standard
for connecting hard disks, tape drives and scanners to computers.

SDRAM

Synchronous Dynamic Random-Access Memory (DRAM). SDRAM can run at
higher clock speeds than conventional DRAM.
