Tips and information for comfortable use

Computer users may complain of eyestrain and headaches after prolonged use.
Users are also at risk of physical injury after long hours of working in front of a
computer. Long work periods, bad posture, poor work habits, stress, inadequate
working conditions, personal health and other factors greatly increase the risk
of physical injury.

Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis,
tenosynovitis or other musculoskeletal disorders. The following symptoms may
appear in the hands, wrists, arms, shoulders, neck or back:

• numbness, or a burning or tingling sensation

• aching, soreness or tenderness

• pain, swelling or throbbing

• stiffness or tightness

• coldness or weakness

If you have these symptoms, or any other recurring or persistent discomfort
and/or pain related to computer use, consult a physician immediately and
inform your company's health and safety department.

The following section provides tips for more comfortable computer use.

Finding your comfort zone

Find your comfort zone by adjusting the viewing angle of the monitor, using a
footrest, or raising your sitting height to achieve maximum comfort. Observe
the following tips:

• refrain from staying too long in one fixed posture

• avoid slouching forward and/or leaning backward

• stand up and walk around regularly to remove the strain on your leg
muscles

• take short rests to relax your neck and shoulders

• avoid tensing your muscles or shrugging your shoulders

• install the external display, keyboard and mouse properly and within
comfortable reach

• if you view your monitor more than your documents, place the display at
the center of your desk to minimize neck strain

viii

Taking care of your vision

Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive
room lighting, poorly focused screens, very small typefaces and low-contrast
displays could stress your eyes. The following sections provide suggestions on
how to reduce eyestrain.

Eyes

• Rest your eyes frequently.

• Give your eyes regular breaks by looking away from the monitor and
focusing on a distant point.

• Blink frequently to keep your eyes from drying out.

Display

• Keep your display clean.

• Keep your head at a higher level than the top edge of the display so your
eyes point downward when looking at the middle of the display.

• Adjust the display brightness and/or contrast to a comfortable level for
enhanced text readability and graphics clarity.

• Eliminate glare and reflections by:

• placing your display in such a way that the side faces the window or

any light source

• minimizing room light by using drapes, shades or blinds

• using a task light

• changing the display's viewing angle

• using a glare-reduction filter

• using a display visor, such as a piece of cardboard extended from the

display's top front edge

• Avoid adjusting your display to an awkward viewing angle.

• Avoid looking at bright light sources, such as open windows, for extended
periods of time.

Developing good work habits

Develop the following work habits to make your computer use more relaxing
and productive:

• Take short breaks regularly and often.

• Perform some stretching exercises.

• Breathe fresh air as often as possible.

• Exercise regularly and maintain a healthy body.

Warning! We do not recommend using the computer on a couch or
bed. If this is unavoidable, work for only short periods, take breaks
regularly, and do some stretching exercises.

3 System upgrade

Installing and removing a power supply module

The server has two power supply module bays on the rear panel that
accept hot-plug power supply modules. The system ships out with only
a single power supply module installed. You have the option to
purchase an extra power supply module to provide the system with a
redundant power source. A redundant power configuration enables a
fully-configured system to continue running even if one power supply
module fails.

WARNING! To reduce the risk of personal injury or damage to
the equipment, the installation of power supply modules
should be referred to individuals who are qualified to service
server systems and are trained to deal with equipment capable
of generating hazardous energy levels.

WARNING! To reduce the risk of personal injury from hot
surfaces, observe the thermal labels on each power supply
module. You can also consider wearing protective gloves.

WARNING! To reduce the risk of personal injury from electric
shock hazards, do not open the power supply modules. There
are no serviceable parts inside the module.

Caution! Electrostatic discharge can damage electronic
components. Make sure that you are properly grounded before
handling a power supply module.

Caution! Due to chassis airflow disruption, a power supply bay
should never be vacant for more than two minutes when the
server is powered on. Exceeding five minutes might cause the
system to exceed the maximum acceptable temperature and
possibly damage the system components.

Caution! The power supply is only hot-pluggable if you have a
redundant system with two power supplies installed. If you
only have one power supply installed, before removing or
replacing the power supply, you must first take the server out
of service, turn off all peripheral devices connected to the
system, turn off the system by pressing the power button, and
unplug the AC power cord from the system or wall outlet.

To install a second power supply module:

1 Observer the ESD precautions described on page 35.
2 If a filler panel is installed, remove the filler panel.

(1) Using your thumb and index finger, squeeze the filler panel

latch to release the filler panel from the chassis.

(2) Pull the filler panel out of the power supply module bay.

75

3 Insert the new power supply module into the empty module bay,

until it locks into place.

76

3 System upgrade

To remove a power supply module:

Caution! Power supply hot-plug operations should be performed
only if a failure occurs in the power supply.

1 If there are more than one power supply modules installed,

determine which power supply module has failed.
2 Remove the AC power cord from the power supply being replaced.
3 Remove the power supply module.

(1) Press the power supply latch to release the power supply

module from the chassis.

(2) Use the handle to pull the power supply module out of the

server.

4 Install a new power supply module or install a filler panel to the

empty bay.

4 System BIOS

This chapter gives information about the
system BIOS and discusses how to configure
the system by changing the settings of the
BIOS parameters.

79

BIOS overview

BIOS setup is a hardware configuration program built into the system's
Basic Input/Output System (BIOS). Since most systems are already
properly configured and optimized, there is no need to run this utility.
You will need to run this utility under the following conditions.

• When changing the system configuration settings

• When redefining the communication ports to prevent any conflicts

• When modifying the power management configuration

• When changing the password or making other changes to the
security setup

• When a configuration error is detected by the system and you are
prompted ("Run Setup" message) to make changes to the BIOS
setup

Note: If you repeatedly receive Run Setup messages, the battery
may be bad. In this case, the system cannot retain configuration
values in CMOS. Ask a qualified technician for assistance.

BIOS setup loads the configuration values in a battery-backed
nonvolatile memory called CMOS RAM. This memory area is not part of
the system RAM which allows configuration data to be retained when
power is turned off.

Before you run the PhoenixBIOS Setup Utility, make sure that you have
saved all open files. The system reboots immediately after you close the
Setup.

Note: PhoenixBIOS Setup Utility will be simply referred to as

"Setup" or "Setup utility" in this guide.

The screenshots used in this guide display default system values.
These values may not be the same those found in your system.
