Important Safety Information
For your own safety and that of your equipment, always take the following precautions.
Important: The only way to shut o power completely is to unplug the power cord.
Make sure at least one end of the power cord is within easy reach, so you can unplug
the Xserve when you need to.
Disconnect the power plug (by pulling the plug, not the cord) if any of the following
conditions exist:
You want to remove any parts (leave the cord disconnected as long as the cover Â
is o).
The power cord or plug becomes frayed or otherwise damaged. Â
You spill something into the case. Â
The Xserve is exposed to rain or any other excessive moisture. Â
The Xserve has been dropped or the case has been otherwise damaged. Â
You suspect that the Xserve needs service or repair. Â
You want to clean the case (use only the recommended procedure described later). Â
Be sure that you always do the following:
Keep the Xserve away from sources of liquid, such as washbasins, bathtubs, shower
Â
stalls, and so on.
Appendix
49
Protect the Xserve from dampness or wet weather, such as rain and snow. Â
Read all the installation instructions carefully before you plug the Xserve into a Â
grounded electrical outlet or power strip.
Keep these instructions handy for reference by you and others. Â
Follow all instructions and warnings dealing with the Xserve. Â
Electrical equipment may be hazardous if misused.
The model of server described in this manual is certied only as a component for use
with other equipment, where the suitability of the combination has been determined
by a Nationally Recognized Testing Laboratory.
Handling the Xserve
Follow these guidelines for handling the Xserve and its components:
When the Xserve is removed from the rack, set it on a sturdy, at surface. Â
Important: Do not put a display or any other device on top of the Xserve. Any
weight on top of the case could damage essential components inside the Xserve.
When connecting or disconnecting a cable, always hold the cable by its connector Â
(the plug, not the cord).
Certain components and cables—hard disks, a VGA monitor, FireWire, Ethernet, and Â
USB devices—are designed to be installed or removed while the Xserve is turned on
and operating.
Never force a connector into a port. If the connector and port do not join with Â
reasonable ease, they probably don’t match. Make sure that the connector matches
the port and that you have positioned the connector correctly in relation to the port.
50 Appendix B Safety and Maintenance
Take care not to spill any food or liquid on the Xserve or other components. If you Â
do, turn o the Xserve immediately and unplug it before cleaning up the spill.
Arrange for an Apple Authorized Service Provider to inspect or repair the Xserve.
Protect the Xserve and its components from direct sunlight and rain or other Â
moisture.
Keep all ventilation openings clear and unobstructed. Without proper air circulation, Â
components can overheat, causing damage or unreliable operation.
Protecting the Optical Drive
To keep the optical drive working properly:
In an emergency, you can eject a disc by holding down the mouse button as the Â
system starts up. If no mouse is attached, you can eject the disc by using the front
panel controls to start up from the optical drive. For instructions, see the Xserve User
Guide on the Admin Tools disc that comes with the Xserve.
Whenever possible, eject the disc before shutting down.
Power Supply
The power supply in the Xserve is a high-voltage component that should not be
opened for any reason, even when the computer is o. If the power supply needs
service, contact an Apple Authorized Service Provider.
51Appendix B Safety and Maintenance
Cleaning the Xserve
Follow these recommendations when cleaning the outside of the Xserve:
Use a damp, soft, lint-free cloth to clean the exterior. Avoid getting moisture in any Â
openings.
Don’t use aerosol sprays, solvents, or abrasives. Â
Cleaning the Xserve Case
To clean the case:
1 Turn o the computer completely and then disconnect the power plug (pull the plug,
not the cord).
2 Wipe the surfaces lightly with a clean, soft cloth dampened with water.

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.
