Hazardous voltages exist on the power supply. To avoid electrical
shock, disconnect the power from the instrument before
performing the following procedures. After disconnecting the
power, wait at least six minutes for the capacitors on the power
supply board to discharge before servicing the instrument.
Damage can occur to electronic components if you remove or
replace assemblies when the instrument is on or when the power
cable is connected. Never attempt to remove or install any assembly
with the instrument on or with the power cable connected.
There are several ways to power off the logic analysis
system.
When powering off the logic analysis system, wait until the fans stop
turning (about 15 seconds) before turning the logic analysis system
back on. This ensures that internal circuitry restarts in a known
state.
Using the Windows Shutdown
On the logic analysis system desktop click Start> Shut
Down or if you are running remote desktop, click Start>
Settings> Windows Security> Shut Down. This software
power off does the following:
• Closes all programs that are running.
• Writes all data to the disk.
