An RJ-45 connector is used for both telephone and twisted pair Ether­net (TPE) connectors. Mismatching the two connectors may destroy
your telephone as well as your PENT/CPCI-721. Therefore:

• TPE connectors near your working area have to be clearly marked
as network connectors.

• TPE bushing of the system has to be connected only to safet y extra
low voltages (SELV) circuits.

• The length of the electric cable connected to a TPE bushing must
not exceed 100 meter.

If a Lithium battery on th e board has to be exc hanged, obser ve t he fol­lowing safety notes:

• Incorrect exchange of Lithium batteries can result in a hazardous
explosion.

• Always use the same type of Lithium battery as is already
installed.

Environment

CompactPCI

• Exchange the battery before five years of actual use have elapsed.

• Exchanging the battery always results in a loss of data. Therefore,
back up affected data before exchanging the battery.

• When installing the new battery, ensure that the ’+’ on top of the
battery stays at the top and therefore is visible when viewing the
board from its component side.

Always dispose of used batteries and/or old boards according to your
country’s legislation.

The PENT/CPCI-721 is a system slot board, i.e. it always has to be
operated in the system slot of the CompactPCI rack. The I/O-721 is a
peripheral slot board, i.e. it always has to be plugged into peripheral
slots of the CompactPCI rack. Otherwise the boards and other cards
in the system may be damaged.

variants of the PENT/CPCI-72x. Do not use any other I/O panel on the
Base-720.

IOBP-IO720

Force Computers offers an IOBP-IO720 panel which is plugged into the
CompactPCI backplane from its rear. The panel enables easy connection
to the I/O signals of an I/O board which are available on the I/O

board’s J5 connector.

Caution • The IOBP-IO720 is especially desi gned for the I/O board variants

of the PENT/CPCI-72x. Do not use any other I/O panel s on the I/O-

721.

PMC Module

• Never connect SCSI devices to both SCSI co nnect ors on board t he
IOBP-IO720. Decide whether you want to use 16-bit or 8-bit SCSI.

• Never connect devices to both connectors on board the IOBP­IO720 which carry the PMC user I/O signals. Decide whether you
want to use the full or only t he parti al range of PMC 2 user I/O s ig­nals.

The I/O panel includes an on-board flat cable and industry standard
connector for the PMC user I/O signals and for the SCSI signals.

The I/O-721 provides one PMC slot. If the I/O-721 is shipped without

2 - 12 PENT /CPCI-72 1

Installation Hardware Upgrades and Accessories

Note:

• To ensure proper EMC shielding, always operate a
PENT/CPCI-721 with the blind panels for the PENT/CPCI-721
front panel or with the modules installed.

• If the PENT/CPCI-721 is upgraded, ensure that the blind panels
are stored in a safe place to be used again when removing the
upgrades.

The PMC slot supports 32-bit data bus width with a maximum frequen­cy of 33 MHz. A power supply of +/- 12V is available at the PMC slots.

Voltage Keys

The PCI bus uses a 5V voltage signal level on the PMC slots. The voltage
keys prevent 3.3V PMC cards from being plugged into the PMC slots.

Connector Configuration

Caution The total maximum power consumption per PMC slot at +/-12V, 5V

Installation Procedure

The 32-bit PCI bus requires two PMC connectors. The third PMC con­nector connects additional user I/O signals of the PMC slot with the
I/O-721 CompactPCI J5 connector. The CPU board provides a limited
current at the PMC supply pins.

Note: On the I/O-721, the PMC slot 1 provides three PMC connectors
(see Figure 7 “Mounting Points 2M1, ..., 2M5 of PMC Module on the
I/O-721” on page 2-14).

The different PMC slot numbering also results in a different pinout for

the I/O board’s CompactPCI connector and for the PMC user I/O con­nectors provided on the IOBP-IO720.

and 3.3V level must not exceed 7.5W (total over all used voltages).

PENT/CPCI-721 2 - 25

Battery Installation

Battery

The board is designed to be maintenance-free. However, note that a
Lithium battery is installed on the board. The battery provides a data
retention of five years summing up all periods of actual battery use.
Therefore Force Computers assumes that there usually is no need to
exchange the Lithium battery except for example in the case of long­term spare part handling.

Caution • Incorrect exchange of Lithium batteries can result in a hazardous

explosion.

• Exchange the battery before five years of actual battery use have
elapsed.

• Exchanging the battery always results in data loss of the devices
which use the battery as power backup. Therefore, back up
affected data before exchanging the battery.

• Always use the same type of Lithium batt ery as is already
installed.

• If the battery is covered by a PMC module on slot 1 or a memory
module, the module must be removed first.

• Do not use a screwdriver to remove the battery from its holder to
avoid possible damage to the PCB or the battery holder.

• When installing the new battery ensure that the ‘+’ on top of the
battery stays at the top and therefore is visible when viewing the
board from its component side.

• If necessary reinstall the PM C or memory module in its correct
position.

Keys

The PENT/CPCI-721 provides front panel keys which will be descri bed
below.

Reset Key

When enabled and toggled, it instantaneously a ffects the CPU board by
generating a reset. The reset generates a PCI reset and is programmable
to be globally or local to the CPU board via the PCI Bus Control Regis­ter.

A reset of all on-board I/O devices and the CPU is performed when the
reset key is pushed to the active position. RESET is held active until the
key is back in the inactive position, however at least 200 ms are guaran­teed by a local timer. Power fail (below approxima tely 4 .7V) and power

up – both lasting at least 200 ms to 300 ms – also force a reset to start the
CPU board.

Abort Key

When enabled and toggled, it instantaneously a ffects the CPU board by
generating an interrupt request (NMI) via the PCI-to-ISA bridge. This
allows to implement an abort of the current program, to trigger a self­test or to start a maintenance program.

Note: For information on how to disable the keys, see the “Action
Plan” section on page 2-10.

As a factory option the VGA-IO720-4 graphics controller based on the
Chips&Tech 69030 graphics device is installed on the I/O-721 board
providing the following graphics modes:

• 1600x1200 dots resolution and max. 65536 colors at max. 60 Hz verti­cal refresh

• 1280x1024 dots resolution and max. 16.777.216 colors at max. 75 Hz
vertical refresh

• 1024x768 dots resolution and max. 16.777.216 colors at max. 100 Hz
vertical refresh

• 800x600 dots resolution and max. 16.777.216 colors at max. 100 Hz
vertical refresh

• 640x480 dots resolution and max. 16.777.216 colors at max. 100 Hz
vertical refresh

Danger Make sure to use only the graphics modes and refresh ra tes supported

by your monitor or displa y devi ce. Otherwise temporary malfunction
or permanent damage may occur to your monitor or display device.
This could cause fire and personal injury. We recommend consulting
the manual of the attached monitor or display device before setting
the graphics mode. For testing and setting up a low resolution mode

e.g. 640x480 at a low vertical refresh rate e.g. 60Hz should be a safe
starting point. If your monitor shows a distorted picture or produces
audible sounds, immediately switch off the monitor and check for
supported graphics modes and refresh rates.

Note: Although always assembled, the VGA connector will only pro­vide VGA signals if the VGA-IO720-4 has been installed.

BIOS

BIOS Features

Features

The PENT/CPCI-72x is designed to run with Windows NT Version 4.0.
The initial boot-up procedure is performed by BIOS which provides the
following features:

• Upgradable via software utility

• PCI 2.1 compliant

• Plug-and-Play 4.0 compliant (PnP)

• DMI 2.00.1 BIOS support

• Advanced Power Management

• Hardware setup

• Hardware initiali zation at boot: At power on or reset, BIOS performs
Power-On Self Test (POST) routines to test system resources. After­wards it loads and starts the operating system.

PENT/CPCI-721 4 - 3

Boot Selection Menu BIOS

Boot Selection Menu

BIOS automatically starts during power-up or reset.

Press <Esc> while boot-up screen is displayed to continue with the
POST screen until the end of POST. Then the boot selection menu is dis­played. In the boot menu, you will find the following options:

1. Override existi ng boot sequence (for this boot only) by selecting
another boot device from boot-order list
If the specified device does not load the operating system, BIOS
reverts to previous boot sequence.

2. Enter Setup

3. Pres s <Esc> to return to the POST scre en and continue with previous
boot sequence

BIOS Setup

Setup

BIOS provides the Setup program to configure the setting of a wide
range of system board features.

Press <F2> to enter Setup. The following options are displayed:

• LPT, COM1 and COM 2 can be remapped via the advanced configu­ration option for integrated peripherals in BIOS setup.

• The IDE devices can be configured via the main configuration
options for primary and secondary IDE masters and slaves and via
the advanced configuration option for intergrated peripherals. This
configuration capability is used for example at the first boot after
connecting an IDE device.

• The floppy type can be configured via the respective main configu­ration options for diskettes. This configuration capability i s used f or
example at the first boot after installi ng a floppy via the respective
I/O panel.

• The video system type can be configured via the related main con­figuration option. This configuration capability is for example used
at the first boot after installing the VGA accessory kit.

PENT/CPCI-721 4 - 5

Boot Configuration BIOS

Boot Configuration

The boot configuration options in Setup let you select the order of the
devices from which BIOS attempts to boot the operating system. During
POST, BIOS tries the next one on the list if it is unsuccessful at booting
from one device.

Each device listed represents the first of a group of devices if more than
one device of this group is install ed o n the system. For example, if there
is more than one hard disk drive, the displayed entry represents the first
of these drives as specified in the boot configuration option for fixed
media. The same applies to removable media.

The same options determine the order in which POST installs the devic­es and the operating system assigns device letters. BIOS supports up to
two floppy devices, to which the operating system may assign, for ex­ample, drive letters A: and B:.

C:, D:, E:, etc. are assigned to hard-disk drives.

Note: There is not always an exact correspondence between the order
specified in these menus and the letters assigned by the operating
system. Many devices such as legacy option ROMs support more than
one device, which can be assigned more than one letter. If you want
the CD-ROM drive to be listed before the hard drive, move it in front
of the hard drive. The group of bootable add- in cards refers t o devices
with non-m ultiboot-c ompliant BIOS option ROM from whic h you
can boot the operating system.

BIOS Boot Configuration

Figure 30: Sample Setup Showing the Boot Config ura tio n Optio ns

In the example above BIOS attempts to boot in the following order:

1. Diskette Drive - from floppy disk

2. Removable Devices

3. Hard Drive - from hard disk

4. ATAPI CD-ROM Drive

Note:

• If you save changes yo u made in Setu p, the selections in the
menus are stored in NVRAM (CMOS). The next time the system
board boots, BIOS configures the system according to the Setup
selections stored in NVRAM (CMOS). If those values cause the
system boot to fail, reboot and press <F 2> to enter Setup. In Setu p,
you can get the default values or tr y to change the selectio ns that
caused the boot to fail.

• If you get the default values, note that the displayed default val­ues are not yet stored to be effective for the next boot. They are
just loaded to be displayed. However, they are effective when the
current boot-up procedure is resumed.

Boot Configuration BIOS

Depending on the messages displayed, there are other keyboard inputs
resulting in calls to special BIOS set-up programs, including, for exam­ple, <Ctrl>+<A> to enter the SCSI BIOS for the dual-segment variant.
If the BIOS or an Option ROM (e.g. of an add-on card) requests key­board input, you are prompted to enter the information. POST contin­ues from there with the regular POST screen.

Note: Whenever POST detects a non-fatal error, BIOS displays the
errors. It then displays a message asking you to choose between boot
continuation or error correction via Setup.

BIOS Sample Start-Up

Sample Start-Up

The following figure shows a sample start-up message following the
video BIOS message which displays the graphic card type and the video
RAM size.

Figure 31: Sample Start-Up Message

Note:

• The NVRAM (CMOS) values may have been corrupted or modi­fied incorrectly, perhaps by an application program that changes
data stored in NVRAM (CMOS). BIOS detects such problems by
verifying a so-called "System CMOS Checksum".

• If, during bootup, BIOS detects a problem in the integrity of val­ues stored in NVRAM (CMOS), it displays a message asking you
to choose between boot continuation or entering Setup with the
ROM default values already loaded into the menus.

• After entering Setup with the ROM default values alre ady loa ded
into the menus, it might b e possible to restore some values as
saved in NVRAM (CMOS) via the exit configuration option to
load previous values.

SCSI BIOS

SCSI BIOS Features

Features

The SCSI BIOS must be enabled if you want the system to boot from a
SCSI hard disk drive connected to the adapter. If the devices on the SCSI
bus are controlled by device drivers and therefore do not need a BIOS,
you can disable the SCSI BIOS to free about 16 KBytes of memory. This
also shortens the boot time by up to 60 seconds.

The SCSI BIOS provides two functions to support user configuration:

• Listing of the actually used SCSI IDs and correlated LUNs

• Setup options to adapt the CPU board and its SCSI configuration to
the user’s needs. The default configuration is marked within SCSI
BIOS Setup.

The SCSI IDs are listed during boot up when entering SCSISelect. You
can list actually assigned SCSI IDs within the BIOS Setup when you se­lect the SCSI disk utilities from the initial SCSI BIOS Setup screen.

If you need to know the available LUNs, select the SCSI device you
want to configure. If there are multiple logical units, SCSI BIOS displays
a menu of correlated LUNs.

Some Setup options apply to the host adapter; other options apply indi­vidually to each device on the SCSI b us. In some c ases the al lowable va l­ue range depends on the actual SCSI bus width used (8-bit or 16-bit).
Some Setup options list the current device settings for each SCSI ID,
even IDs not assigned to a device.

PENT/CPCI-721 5 - 3

Features SCSI BIOS

Note:

• In case of display problems press <F5> to toggle the display
between color and monochrome. This feature may not work on all
monitors.

• The default settings are appropriate for most appli cations, so there
usually is no need to change t he settings. I f you have to c hange the
settings of the advanced configuration options listed below, you
should ensure that you thoroughly understand the consequences
of the change before actually doing so.

Selectable Host Adapter SCSI ID

SCSI IDs range from 0…7 if the respective device i s operated on an 8- bit
SCSI bus and from 0…15 on a 16-bit SCSI bus . For 8-bit devi ces, ID 7 has
the highest priority and ID 0 has the lowest priority. For l6-bit devices,
the priority of IDs is 7 … 0, then 15 … 8. In this case, ID 7 has the highest
priority and ID 8 has the lowest priority. Each host adapter (8 - or 16-bi t)
has the default SCSI ID of 7, which gives the adapter the highest priority
on the SCSI bus.

Note: Host adapter SCSI termination: The configuration of the host
adapter SCSI termination within SCSI BIOS is not suppo rted because
the SCSI termination is controlled by SW0900C and SW0900D (see
page 2-13).

SCSI Parity Checking

Each adapter uses SCSI parity checking to verify the accuracy of data
transfer on the SCSI bus. Most currently available SCSI devices support
SCSI parity check. If a device on the SCSI bus does not support it, dis­able parity checking.

Selectable Boot Device

Selectable boot device by specifying the boot target ID (and LUN in case
the device has implemented multiple logical units).
