Installation guidelines
Before you install optional devices, read the following information:
v Read the safety information that begins on page v and the guidelines in
“Handling static-sensitive devices” on page 18. This information will help you
work safely.
v
Before you install optional hardware, make sure that the operating system starts,
if an operating system is installed, or that a 19990305 error code is displayed,
indicating that an operating system was not found but the server is otherwise
working correctly. If the server is not working correctly, see the Problem
Determination and Service Guide for diagnostic information.
v
Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and other devices.
v Observe good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
v
If you must start the server while the cover is removed, make sure that no one is
near the server and that no tools or other objects have been left inside the
server.
v
Do not attempt to lift an object that you think is too heavy for you. If you have to
lift a heavy object, observe the following precautions:
– Make sure that you stand safely without slipping.
– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy
object.
– To avoid straining the muscles in your back, lift by standing or by pushing up
with your leg muscles.
v Back up all important data before you make changes to disk drives.
