Setting System-Board Configuration Switches
Setting System-Board Configuration Switches
Some configuration actions are controlled through switches on the
system board. Table 15 summarizes the switch settings that
correspond to these actions.
Table 15. Configuration Switch Settings
Switch Position Function
S6A1-1 On
Off 1
Resets NVRAM and the Real-Time
Clock (RTC) to the factory defaults on
system startup.
Retains current CMOS settings on
system startup.
S6A1-2 On
Off 1
Clears the user and administrative
passwords on system startup.
Passwords can be entered or changed.
S6A1-3 Off 1 Reserved
Notes:
1. This is the factory default.
2. Do not change the settings for switches S6A1-4, S6A1-5, S6A1-6, or
S6A1-8. These switch settings should remain as set at the factory.
Resetting NVRAM and the RTC (Switch S6A1-1)
Setting the CMOS switch to On clears the current values of NVRAM
and the RTC when the server is reset. This returns NVRAM and
the RTC to the factory default.
When the CMOS switch is set to Off, the default, the current
settings are preserved during system reset.
