both SW1-1 and SW1-2 to either the ON position or both to

5. Start the PC’s HyperTerminal program (at 115.2 kbaud) and
generate a receive using the 1KX-Modem protocol. Save the
resulting core updump in a file so you can forward it later to the
technical support group.
By setting the CPU/System Controller board switches SW2-1 and SW2-
4 both off before the ControlWave GFC Plus fails you prevent the GFC
Plus from automatically recovering from the failure and enable it to wait
for you to take a core updump.
Once you complete the core updump, set the CPU/System Controller
board’s switch SW2-1 to ON (Watchdog Enabled). Additionally, set
switch SW1-1 to OFF and SW1-2 to ON.
With these switches set, power up the ControlWave GFC Plus and begin
standard operations.
