Removing the cover
The following illustration shows how to remove the cover.
Important: Before you install optional hardware, 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 the
Problem
Determination and Service Guide for diagnostic information.
To remove the cover, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 38.
2. If you are planning to view the error LEDs that are on the system board and
components, leave the server connected to power and go directly to step 4 on
page 45.
