z Power-up procedure
z Runtime switches and indicators
2.2 Applying Power
After you verify that all necessary hardware preparation is complete and all connections are
made correctly, you can apply power to the system.
When you are ready to apply power to the MVME3100:
z Verify that the chassis power supply voltage setting matches the voltage present in the
country of use (if the power supply in your system is not auto-sensing)
z On powering up, the MVME3100 brings up the MOTLoad prompt, MVME3100>
2.3 Switches and Indicators
The MVME3100 board provides a single push button switch that provides both abort and reset
(ABT/RST) functions. When the switch is pressed for less than five seconds, an abort interrupt
is generated to the processor. If the switch is held for more than five seconds, a board hard reset
is generated. The board hard reset will reset the MPC8540, local PCI/PCI-X buses, Ethernet
PHYs, serial ports, Flash devices, and PLD(s). If the MVME3100 is configured as the VME system
controller, the VME bus and local TSi148 reset input are also reset.
The MVME3100 has four front-panel indicators. The following table describes these indicators:
