Servicing Motherboard Components 115
■ Replacing a faulty SCC module -- When replacing a faulty SCC module, you
must obtain the host ID, MAC addresses, and ILOM configuration settings stored
in the SCC module you are replacing. This will enable you to configure them into
new SCC module.
See “Remove a Faulty SCC Module” on page 115 and “Install a New SCC Module”
on page 116 for additional information.
Note – Some firmware variable settings are not stored in the SCC module. If you are
replacing a motherboard, these settings will become the factory default settings.
