Ergonomic Notice
Now that you have your Micron computer, you will probably spend many
hours exploring the capabilities of this machine, and personalizing it for your
use. But the computer is only part of the larger picture of ergonomics.
Ergonomics is a science that addresses human performance and well-being in
relation to various types of jobs, tools, equipment and environment.
As you begin to personalize your working environment, it is important to
keep in mind your body’s needs to make your computer time more productive
with less physical and mental stress. And an effective work area will begin
from the ground up. Here are some suggestions:
• Use an adjustable chair, and try different seated postures to find
what is most comfortable and produces the least fatigue. The
backrest should be adjustable to fit the small of your back.
• Use an adjustable keyboard support. You want to keep your
wrists straight, your hands lower than your forearms and your
forearms parallel to the floor. Use a light touch on the keyboard.
• Alternate mouse and keyboard use, and keep the mouse within
easy reach.
• Place the monitor 18-30 inches from your eyes (arm’s length is
also a good distance). The top of the monitor should be level
with your eyes.
• Take breaks from both the keyboard and looking at the monitor.
Performing simple exercises while at your work area will increase
your productivity. Shrug your shoulders...take a deep
breath...change your focus...massage your hands...stretch....let
your arms fall relaxed at your sides.
No two work areas will ever be the same. Find the combinations that work for
you, and keep in mind that proper work area planning will make your
computer time more effective, and less stressful on your body.

Unpacking
Check the Packaging
As soon as the packages containing your new system arrive, carefully inspect
them for any signs of damage. In particular, look for wrinkled or bent corners,
holes, or other signs of bad handling or abuse. If you notice any damage to the
packaging, immediately open the boxes and inspect the contents for damage.
Pay close attention to the components near the area where the packing material
was damaged.
Unpack Your System
Caution: If your system arrives in cold weather, do not unpack the computer
or the monitor until they have been allowed to come to room temperature.
Immediately exposing them to the warm room may cause condensation to
occur, which may damage the units. If condensation does occur, allow the
units to completely dry before operating them.
Follow these steps after you have determined that the packaging is undamaged:
1 . Taking care not to damage the packing material, carefully open
the cardboard box containing the computer and remove the
system unit, keyboard and any other accessories that you may
have ordered.
2. Carefully unpack the monitor and all accessories from the
monitor package. Be careful not to damage the packing material.
3 . Inspect all items for damage that may have occurred during
shipment.
For your protection, report any damage to the shipper
immediately.
We highly recommend that you save the packaging in the event that you need
to move or ship the system some time in the future.
Check Your Packing List
Now that you have everything out of the packages, take the time to check the
packing list to be sure you received everything. If you discover that an item is
missing, call Micron Electronics, Inc. immediately to receive a replacement.
Refer to Appendix A for contact information.

Chapter 1: Setting Up Your System
Setup
Getting Started
Before your new system left the factory, Micron configured the hardware. The
display adapter was set to work with your monitor and the hard disk was
partitioned and formatted with DOS using the standard default settings for
your machine. Your computer system is ready to go. All you have to do is
plug it in.
What You Need
❏ A grounded power outlet
❏ Phillips-head screwdriver
❏ Power filter/suppressor protector (recommended)
Putting It All Together
To complete your setup, refer to the following steps:
1 . Take a moment and review the case figures on the following
pages to acquaint yourself with the front and back of your system.
2 . Check the voltage selector on the rear of the unit. Be sure it is
switched for the proper voltage (115V in the United States and
Canada).
3 . Place the monitor where you wish, as long as its cable can still
reach the video connector at the rear of the computer.
4. Unpack the power cable for the computer and plug the
appropriate end into the power inlet at the back of the system.
Insert the other end into a grounded power outlet. We highly
recommend that you obtain a protection device such as an
uninterruptable power supply (UPS), power filter or surge
suppressor. In this way you will be providing the utmost
protection for your system and data.
5. Ensure that the system is turned OFF before proceeding.
Attaching peripherals while the power is on may damage the
unit or the peripheral.
6 . Locate the monitor’s power cable and plug the appropriate end
into the monitor (if not already attached). Insert the other end
into the grounded outlet or protection device.
Micron Electronics, Inc. 1-3
Micron NetFRAME LV2000 Server System User’s Guide
7 . Find the video cable and attach the appropriate end into the
monitor (if not already attached) and attach the other end into
the video connector (located in one of the expansion slots at the
rear of the unit). If the connection is loose on either end, tighten
the integrated screws at both ends of the cable for a secure
connection. For more information about the setup, use, and
maintenance of your video monitor, please refer to the manual
that was supplied with it.
8. Insert the ends of the keyboard and mouse cables into the
keyboard and mouse connectors at the rear of the computer
system. Take care, for the connectors are keyed in such a way
that the plugs can only be inserted if oriented correctly. Refer to
the case drawings on the following pages for the location of the
proper connector. If it does not plug in easily, do not force it.
Your system should now be ready to use. You may have other devices or
peripherals to install, but it is best to ensure the basic system is operating
correctly before adding any options.

Chapter 1: Setting Up Your System
Running Your System for the First Time
1 . Power up the monitor. If you are unsure about this, please refer
to the monitor’s manual for more information.
2 . Remove any floppy disks from the floppy drive.
3 . Power up the computer system by firmly pushing and releasing
the On/Off button on the front panel of the system. The power
indicator should light up and the fan and hard drive should begin
to run.
The system diagnostics begins at this time. The keyboard is initialized indicated
by the keyboard LEDs blinking momentarily. The Num Lock LED remains
on. Next, the screen initializes and a message indicating what type of video
adapter is installed. The memory will be counted and tested.
Finally, the system is booted.
If you experience any problems during the power up sequence, please refer to Chapter
4, "Common Problems."
Turning Off Your System
Micron recommends that you power down your system in the following order:
1 . Exit all applications you are running and save any changes.
2 . Make sure that ALL disk activity has completely stopped. The
floppy and hard drive indicator lights should be off and the
floppy drive motors should stop. Hard disks continue to spin
until the system power is shut off.
3 . Turn off the computer system, then the monitor.
Micron Electronics, Inc. 1-7
Micron NetFRAME LV2000 Server System User’s Guide
Maintenance
Operating Environment
Your Micron computer has been manufactured to the highest standards. With
proper care, it should provide years of trouble-free service.
To ensure that your system has the longest life possible, it should be placed in
an area with good ventilation and low humidity, out of direct sunlight and
away from heat sources or lamps. Be sure the rear cooling-fan opening is not
obstructed as it is necessary to keep the system cool. Never expose the system
to any moisture. This could lead to fire or shock hazard. Stay away from areas
with high levels of dust, dirt, or smoke.
Transporting
Always shut the system off before moving it. Any sudden jar or shock may
permanently damage the hard drive. Hard drives are more resistant to shock
if they are shut down.
If you are transporting the system over a distance, it is a good idea to completely
repackage it in its original packing material. If the original packaging is
unavailable, pack all components with as much padding as reasonably possible
to ensure that the units are not exposed to excessive vibration or shock.
Cleaning
If the case becomes dirty through constant use or handling, use only a damp,
dust-free cloth for cleaning. Do not use abrasives or solvents as these may mar
or scratch the case. Window cleaner and a cloth can be used to clean the monitor,
if the monitor has been turned OFF first. Never apply the window cleaner
directly to the monitor screen. Always spray the cloth first, then wipe down
the screen.
Cleaning kits designed to clean floppy drives are available from most computer
stores and should be used periodically.
If you are operating your system in an environment heavy with smoke or
dust, you should occasionally open the unit and with great care, clean the
components with a vacuum (special vacuums are available just for this
purpose). Be careful to not loosen any of the components.
If liquid is spilled into the keyboard, immediately unplug it, allow the fluid to
drain out by tipping the keyboard upside down, and dry the keyboard
overnight before using it again.
1-8 Micron Electronics, Inc.
Chapter 1: Setting Up Your System
Protecting
To prevent normal electrical problems such as spikes or surges, install a power
surge/filter between the power outlet and all of the connected components. If
even one component is not connected, the entire system could be at risk.
If a severe storm enters your area, completely unplug the entire system from
all electrical sources, including phone lines. Lightning can travel in on any
line and destroy all connected components.
If possible, do not turn the system on and off frequently. This stresses the
power supply and may shorten the life of some components. To restart the
system, press the reset button located in the front of the case. If applications
are open and the system is reset or if the hard drive is active, data loss will
most certainly occur. If you do not use the reset button to restart the system, be
sure the hard drive has come to a complete stop before turning the computer
on again.
Backing Up
Even with today’s technology, data loss can occur at any time. We highly
recommend that you back-up often. There are a large number of backup systems
available from retail and mail-order outlets, including floppy drive backup
systems, tape backup systems, and optical backup systems. Any of these
alternatives are highly recommended. Complete, frequent backups can save
years of data from total and irretrievable destruction. If you require additional
information about backup systems or options, please contact Micron
Electronics, Inc.
Micron Electronics, Inc. 1-9
Micron NetFRAME LV2000 Server System User’s Guide
Removing the System Cover
Refer to the Figure on page 1-13. Use a #2 Phillips-head screwdriver or a 1/4"
hex driver.
1 . It is not necessary to disconnect the cable connectors on the back
of the computer before opening the cover. However, note where
the cables connect to the back for future reference . (If you have
a video camera, a quick scan of the rear case is helpful).
2 . Remove the screws from the back of the case cover. Keep these
screws together (they are a different size than the other screws
in your system) for they are not to be interchanged.
3 . With flat palms placed on each side of the cover, pull the cover
back until the cover's front top lip clears the chassis channel
(about 3/4"). Grasp the top-rear of the cover and lift up in one
smooth motion until the cover clears the chassis.
To replace the cover, gently lower the top lip of the cover into the chassis
channel at an angle before lowering the rear into place. With the lip inserted
in the channel, push the rear of the cover forward to seat it flush and replace
the screws. Note the metal rail guides located inside the bottom of the cover
which must fit over the bottom metal case frame when the cover is replaced.
