Boot Up and Initialization Troubleshooting
CXA Instrument Boot Up Process
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.
NOTE 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.
4. Both instrument fans should start running. The fans are mounted on the
left-hand side of the analyzer and draw air into the instrument to cool the
internal circuitry. If either fan is not running refer to the “Fan(s) Are Not
Operating” section in this chapter.
5. The Agilent Technologies splash screen is displayed in white font on a dark
background for ~5-10 seconds after the analyzer is turned on. If the Agilent
Technologies logo is not displayed refer to the “No Agilent Splash Screen
Displayed” section in this chapter. If the instrument hangs at the Agilent
Technologies splash screen refer to the “Instrument Hangs at the Agilent
Splash Screen” section in this chapter.
6. Verify text is displayed on screen where the user has the option of booting
Windows XP or running the Agilent Recovery System. The default selection is
to boot Windows XP. If a recovery is required, press the Down Arrow key on
the front panel of the analyzer within 5 seconds to highlight “Agilent Recovery
System” and press the Enter key on the analyzer, otherwise Windows XP will
begin to boot. If the Windows XP boot screen is not displayed within a few
seconds refer to the “Instrument Cannot Completely Load or Run the Operating
System” section in this chapter.
7. If the recovery system is not selected the Windows XP Professional operating
system will begin to boot up. This will take ~20-30 seconds.
NOTE If a recovery was selected follow the on-screen instructions and perform a system
recovery. Additional information about performing a system recovery can be found
in Chapter 7 , “CPU/Disk Drive Troubleshooting,” on page 151 in this manual.
8. Agilent Technologies logo is displayed in white font on a blue background
while Windows finishes loading user preferences. If this does not occur refer to
