Before You Begin; Working Inside The Server With The Power On; System Reliability Considerations - IBM xSeries 200 Hardware Maintenance Manual

For typical operation of the system, a jumper is installed on pins 1 and 2 of the
complementary metal oxide semiconductor (CMOS) jumper. See "Clearing CMOS"
on page 15 for information about the CMOS jumper.
