4.1 Tools Required for Maintenance
The actual maintenance work described in Chapter 5 to Chapter 15 requires
maintenance software to confirm that the server and other components are operating
correctly and to collect status information and log data on the server and
components. Work for mounting, removing, or replacing a specific component
requires special tools, including screwdrivers and an antistatic wrist strap. These
items are generally named maintenance tools and are listed in
