Powering up the system
1. Connect the power cord to the rear panel of the con-
troller unit and plug the power cord into a power bar.
2. Connect the power bar to a power outlet.
3. Check the Power LED. During the power up
sequence the Power LED will display the following
states:
- initially flashes red
- flashes green/off while the system is booting
- steady amber while running startup diagnostics
- flashes amber while running bootrom VxWorks
- steady green when bootup is complete.
Never disconnect the system power if the LED is
flashing red and amber.
Do not leave the RS-232 diagnostics cable discon-
nected from the computer or laptop COM port dur-
ing system bootup (that is, either connect the cable
to the PC or disconnect it from the diagnostics port).
