Health-Related Information About Computer Use

In most instances, you’ll probably set up and administer the Xserve from a remote

location, such as an administrator computer on the same network. If you work at the

server rack for extended periods, be sure to follow these guidelines for avoiding muscle

soreness, eye fatigue, or other discomfort associated with computer use:

If feasible in the server location, use an adjustable chair that provides rm, Â

comfortable support. The back of the chair should support your lower back (lumbar

region). Follow the manufacturer’s instructions for adjusting the backrest to t your

body properly.

When using a keyboard at the server location, your shoulders should be relaxed. Your Â

upper arm and forearm should form an approximate right angle, with your wrist

and hand roughly in a straight line. Depending on the location of the display and

keyboard connected to the Xserve, you may have to adjust the height of your chair

so that you can maintain a comfortable position. Your feet should be at on the oor

or on a footrest.
