    This system board manual is written for a trained service provider who intends to install the SPARCserver 1000™ or SPARCserver 1000E™ system board. In general, the term SPARCserver 1000 refers to both the SPARCserver 1000 and the SPARCserver 1000E system board. Where the SPARCserver 1000E is different, this is explicitly noted.
