Typical instrument boot-up process flow
1. Plug in the AC power cord from a known good AC power source into the
rear panel of the analyzer.
2. The yellow standby LED illuminates on the analyzer front panel to the
left-hand side of the On/Off button. If the yellow Standby LED is not
illuminating refer to the “Yellow Standby LED Does Not Illuminate” section
in this chapter.
3. To turn the analyzer on, press the On/Off button. The yellow Standby LED
should turn off and the green Power On LED should illuminate. A green
Power On LED indicates that the power supply has received an “On”
command from the A4 CPU assembly. If the green Power On LED is not
illuminating refer to the “Green Power On LED Does Not Illuminate”
section in this chapter.
If the analyzer AC power source was removed by the operator by pulling the power cord or by
turning off the analyzer via a power main switch on a test rack, the analyzer will automatically
power on without having to press the On/Off button on the front panel.
