iLO/Spread Spectrum Switch (SW8)
The iLO/Spread Spectrum switch (SW8) is a two-position switch that is used for
miscellaneous purposes. The iLO security override switch allows the administrator full access
to the iLO processor. This access is necessary if the administrator password is lost or if the
iLO boot-block needs to be flashed. Figure 4-19 and Table 4-22 identify the iLO/Spread
Spectrum switch location and settings.
