There are two recessed pushbutton switches on the front-panel of the SC:
DO NOT use these pushbuttons to shutdown or reset the Sun™ Solaris™

SA Synchronization and Alarm RTM

The SA alarm rear termination modules (SA/RTMs) provide the chassis management
capabilities for the SC boards, by controlling the fans operation, monitoring the correct
operation of the power supply modules, monitoring the midplane voltages, controlling
the chassis LEDs and Telco alarm relays. It functions as an I/O extension of the SC
functionality and it interconnects with all of the chassis elements. Each SA board is
hot swappable, allowing replacement during maintenance operation. In addition to the
console port on the SB board itself, the SA/RTM provides an RS-232 console serial
port for interconnection with the SC board. The terminal block connector connects
external electrical connections for triggering external devices according to Critical,
Major, and Minor alarms.
The following list summarizes the SA functionality:
Monitoring all midplane voltages
Monitoring correct operation of all power supplies
Controlling chassis temperature by changing fans' speed
Monitoring the fans' speed
Controlling the state of alarm relays
Controlling the front panel chassis LEDs

Function
Indicates that the board can be extracted from the chassis.
When a board is inserted into a system, the LED is lit
automatically until the hardware connection process is
completed
The LED then remains off until the extraction is once again
enabled when opening the extractors
WARNING
ABORT - Pressing the ABORT pushbutton halts the normal
operation of the SC software back to the "OK Prompt" of the
OpenBoot monitor, thereby re-initializing internal programming.
RESET - When the RESET pushbutton switch is pressed, it
generates a Power-On-Reset (POR) signal.
