System maintenance switch
Position Default Function
S1
Off = iLO security is enabled.
On = iLO security is disabled.
S2
Off = System configuration can be
changed.
On = System configuration is locked.
S5
Off = Power-on password is enabled.
On = Power-on password is disabled.
S6
On = ROM reads system
configuration as invalid.
S7
Off = Set default boot mode to UEFI.
On = Set default boot mode to legacy.
To access the redundant ROM, set S1, S5, and S6 to On.
When the system maintenance switch position 6 is set to the On position, the system is prepared to erase
all system configuration settings from both CMOS and NVRAM.
CAUTION: Clearing CMOS, NVRAM, or both deletes configuration information. Be sure to
configure the node properly to prevent data loss.
IMPORTANT:
Before using the S7 switch to change to Legacy BIOS Boot Mode, be sure the
HPE Dynamic Smart Array B140i Controller is disabled. Do not use the B140i controller when
the node is in Legacy BIOS Boot Mode.
