System Specifications
The system requires minimum maintenance and care to keep it
operating properly. A proper environment for the computer means
placing the unit within the appropriate temperature, humidity, and
altitude ranges. See the next table for a list of these environmental
ranges. For the best performance of the computer and for the comfort
of the operator, it is better to place the computer in the middle of these
environmental ranges. It is important that the environmental
conditions not change abruptly.

Guidelines for Locating the System
Before you begin to set up and cable your new system, consider these
guielines for locating your system:
¥ Locate the system in a stable area, free of excess movement and
jarring
¥ Install the system safely; ensure cables and cords are out of the
way
¥ Ensure the set-up is comfortable for users
¥ Allow room for proper air ßow for cooling
Allow at least six inches of space around all sides of the
computer.
¥ Locate the computer where it can be easily serviced (front and
rear)
¥ Provide an area free of excess heat, dust, smoke, and
Electro-Static Discharge (ESD)

Following ESD and Safety Procedures

Wrist Strap
Motorola strongly recommends that you use an antistatic wrist strap
and a conductive foam pad when installing or upgrading the system.
Electronic components, such as disk drives, computer boards, and
memory modules, can be extremely sensitive to ESD. After removing
the component from the computer or its protective wrapper, place the
component flat on a grounded, static-free surface, and in the case of a
board, component-side up. Do not slide the component over any
surface.
If an ESD station is not available, you can avoid damage resulting from
ESD by wearing an antistatic wrist strap (available at electronics
stores). Wrap one end of a wrist grounding strap around your wrist.
Attach the grounding end (usually a piece of copper foil or an alligator
clip) to an electrical ground. An electrical ground can be a piece of
metal that literally runs into the ground (such as an unpainted metal
pipe) or a metal part of a grounded electrical appliance. An appliance
is grounded if it has a three-prong plug and is plugged into a
three-prong grounded outlet. You cannot use the computer itself as a
ground, because it is unplugged when you work on it.
Turn the systemÕs power off before you perform these
procedures. Failure to turn the power off before opening the
Warning computer can result in personal injury or equipment damage.
Hazardous voltage, current, and energy levels are present in
this product. Power switch terminals can have hazardous
voltages present even when the power switch is off. Do not
operate the computer with the cover removed. Always replace
the cover before turning on the computer.

Setting the Power Supply Voltage
Setting the Power Supply Voltage
A switch on the rear panel can be used to set the power supply at:
3
¥ 115V AC (in the range of 90-132 VAC) 60 Hz
¥ 230V AC (in the range of 180-264 VAC) 50 Hz
!
Before powering on the computer, check the switch to ensure
the correct voltage for your location is set.

1. Plug the socket end of the computerÕs power cord into the AC
inlet on the rear of the computer.
2. Connect the socket end of the monitorÕs power cord into the
connector on the back of the monitor.
3. Connect one end of the monitor (video) cable into the port on the

Powering Up the System
Note
3
For proper cooling of the computer and for safety reasons, the
cover should always be installed before you power up the
computer. It must remain in place during system operation.
To start up your computer:
1. Ensure the voltage switch (on the back of the computer) is set to
the correct voltage for your location.
2. Turn on the monitor.
3. Turn on any peripherals attached to the computer.
4. Push and release the power switch on the front of the computer.
The power light on the front of the computer illuminates, and the
indicator lights on the keyboard flash.
In a few seconds, you will now see a series of messages about the:
¥ memory size
¥ processor
¥ Þrmware version
¥ MPU speed
¥ memory bus speed
The system performs self tests to verify that all its internal components
are in working order. The system then begins to initialize the firmware.
The next screen you see is the autoboot screen. It is at this point that you
can halt the boot sequence. If you do halt autoboot, you will be brought
to the firmware level. Depending on the operating system you are
running, your screen will display a firmware screen with a set of
options.
If you do not halt autoboot, autoboot proceeds and begins to load the
operating system.
3-6
Configuring Keyboard Options
Once the operating system finishes booting, a start-up screen and a
login dialog box appear. What appears on your screen depends on the
operating system that is loaded. You can now consult your operating
system manuals and release notes for instructions on logging in and
setting up your operating environment.
This is a good time to adjust the brightness and contrast on your
monitor if the screen display appears dim.
Configuring Keyboard Options
PowerPC Open Firmware International Keyboard Selection
PowerPC Open Firmware provides support for the United States
and some European-style keyboards.
To modify the international keyboard, use the keyboard or mouse
to:
1. Select Advanced Options.
2. Select the Configure Keyboard Options.
A submenu displays listing the supported keyboard styles.
3. Using the Up/Down arrow keys or the mouse, select the
language.
The selected countryÕs keyboard is immediately activated and
remains as the set variable whenever the system is powered up.

Cleaning and Preventative Maintenance
If the housing of the computer needs cleaning, spray a small amount of
a mild household cleaner on a clean, soft, cotton cloth and gently wipe
the surfaces. To avoid getting any liquid into the computerÕs operating
mechanisms, do not spray cleaner directly on the cabinet. For printers,
terminals, or other peripherals, refer to the equipmentÕs user manual
for cleaning instructions.
3
Tape Drive Maintenance
Cartridge tape drives should be cleaned after every eight hours of use.
To prevent loss of data or damage to the cartridge tapes, store them in
a protected location which meets the following requirements:
¥ No direct sunlight
¥ No sources of magnetization
¥ No dust
¥ Temperature range from 50o to 104o F (10o to 40o C), or as stated
on the cartridge cover (may vary from one manufacturer to
another)
Try to place the cartridge tapes in the middle of this temperature
range for best storage results.
¥ Relative humidity range from 8% to 80%
The best storage humidity environment is at the middle of this
range.
¥ To prevent damage to data on the cartridge tapes, avoid
touching the exposed surfaces or breaking open the protective
coverings on the media

External SCSI cable length
(minimum cable length)

Note
All external round SCSI cables up to and including one meter
in length are given an assigned value of one meter. For
example, if a system requires the use of a .5 meter cable, that
cable counts as one meter in the total SCSI bus length equation.
Longer cables are legal and are assigned their actual length
value in the total SCSI length equation.
Even though the SCSI specification allows six meters, it does
recommend a maximum total SCSI bus length of three meters
when fast transfers are performed (as in all Motorola systems).
Many vendors specify a three meter bus length maximum. The
longer the SCSI bus, the greater the chances are for error.

Adding and Configuring Disk Drives
Wide SCSI Device Addressing and Priority
Use these guidelines when setting your deviceÕs address.
¥ The maximum number of devices per wide SCSI bus is 15.
¥ Narrow SCSI devices use IDÕs zero through 6.
¥ SCSI ID 7 is used for the initiator (the controller).
¥ Wide SCSI devices use IDÕs zero through 6 and 8 through 15.
¥ Priority of devices for SCSI bus arbitration is 7 through zero, 15
through 8. Address 7 is the highest priority and address 8 is the
lowest priority. This allows narrow devices (which can only be at
SCSI IDÕs zero through 6) to gain SCSI bus control even if a
device at SCSI IDÕs 8 through 15 is also requesting the bus. This
is necessary since narrow devices do not recognize devices at
SCSI IDÕs 8 through 15.
Note
Removable media devices supported in the system are narrow
drives with wide adapters.
