Important Ergonomic Information
After the server is installed, it is important to apply the following ergonomic
information.
•
Be comfortable in your work space.
•
Change your posture frequently.
•
Proceed according to the recommendations in the following table and
figure.
Adjust So . . .
Chair Feet are flat on the floor.
Legs are vertical forming a right angle to the floor.
Your weight is off your thighs and they are horizontal. Keep the
back of your knees away from the seat so you do not compress
the area behind them, which could restrict the blood flow.
Upper body is erect and lower back is supported with a backrest.
Keyboard or mouse Your wrists are straight and do not bend more than 15 degrees.
They may be supported when resting but not on sharp edges.
Type comfortably, with no more key pressure than needed to
feel the contact point.
Upper arms are straight down at your sides, elbows are close to
your sides and support your arm weight. Forearms are at a 70
degree to 90 degree angle.
If you use a mouse, rest your hand on the mouse so your wrist
is not on the work surface. Operate the mouse close to your
body’s centerline.
Head Avoid neck strain. Your head should incline downward, but no
more than 15 to 20 degrees.
Monitor No higher than the level of your eyes and at the correct distance
for your vision.
Avoid eye fatigue, which can be caused by glare, image quality,
uncomfortable furniture, eye height, and uncorrected vision. If
you cannot focus to read at different distances, you may need
special glasses. Relax your eyes periodically by looking at
distant objects.
