System maintenance switch

The system maintenance switch (SW1) is a twelve-position switch that is used for system configuration. The default position for all twelve positions is Off.

Switch	Settings
1	Off = iLO security enabled On = iLO security disabled
2	Off = Normal operation On = The BIOS configuration is locked.
5	Off = Normal operation On = Password disabled
6	Off = Normal operation On = Clear CMOS and RAM
7*	Off = Set factory default boot mode to UEFI. On = Set factory default boot mode to Legacy.
3, 4, 8, 9, 10, 11, 12	Reserved

* The default position for switch 7 is set in the factory shipping configuration. This switch setting determines the BIOS mode the system defaults to when configuration memory is cleared to factory defaults. The User defined defaults setting in UEFI System Utilities supersedes this switch.

IMPORTANT: To avoid a mismatch between boot modes, Hewlett Packard Enterprise recommends setting system maintenance switch 7 to the same BIOS boot mode the server is deployed in. Otherwise, the storage controller may not recognize the OS installed on the storage media.
