7.3.8 Soft Power Switch
Since the Severworks OSB4 does not have standby voltage the power button may be handled by
the SMSC Super I/O chip (SIO). Currently, the power button in the SRMK2 does a request to
the power state machine in the OSB4. It does not directly control power on the power supply.
7.3.8.1 Going from Power Off to Power On
The OSB4 monitors the power button and turns the system on. When the OSB4 receives power
good it performs a reset to put the system into an ON state. The OSB4 may be configured to turn
the system SRMK2 on for a variety of events including Wake on LAN and Wake on Ring.
7.3.8.2 Going from Power On to Power Off
When the power button is pushed while the system is on it causes the OSB4 to generate a SMI.
The BIOS will then service this SMI and set the state machine in the OSB4 to the off state. As a
safety mechanism, the OSB4 will automatically power the system off if BIOS fails to service the
SMI after 4 seconds. The OSB4 will also power the system off if the power button is pressed
and held for 4 seconds. During power-up the SMI handler that services the power button is not
loaded until SMI is initialized. The SMI handler only sets the state machine in the OSB4 to the
off state if the OS is not yet running. Once the OS is running, the SMI handler leaves the
machine running and allows the OS to handle the power state.
