Before you begin
Important: Before you install optional hardware devices, make sure that the server
is working correctly. Start the server and 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 “Running
DSA Preboot diagnostic programs” on page 149 for information about how to run
diagnostics.
Read the safety information in “Safety” on page vii and “Installation guidelines”
on page 34.
If you are replacing a component or installing an optional device in the server, you
need to turn off the server and peripheral devices, and disconnect the power cords
and all external cables.
