Installing the Hard Drive 2
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.
• Turns off the power supply.
• If the system is unplugged while it is off and then plugged back in, the 
system will not power on until the power button is pressed.
Using a Short Press of the Power Button
Pressing the power button on a frame for a short time (less than 2 
seconds): 
• Closes all programs that are running.
• Writes all data to the disk.
• Turns off the power supply.
If the power button is depressed for a short time (less than 2 seconds or 
so) while another instrument has an open Remote Desktop connection to 
this instrument, a message on the logic analysis system screen (not on the 
remote desktop) will pop up asking if you really want to power down. 
Clicking the 'yes' button results in the above events. Clicking 'no' will 
prevent the shutdown and not answering the dialog box (neither clicking 
"Yes" or "No") will have no effect. Further short presses on the power 
button will have no effect.
Using a Long Press of the Power Button
Pressing the power button for more than 4 seconds will power the system 
down abruptly. Use this method only when other methods have not 
responded:
• Programs that are running will not be shut down. Any data that has not 
been written to the disk will be lost.
• Turns off the power supply.
• If the system is unplugged while it is off and then plugged back in, the 
system will not power on until the power button is pressed.
• If the system does not boot, the hard disk drive will need to be 
re-imaged.
