7 Solving Problems
All 16900 Series logic analysis systems
If the system warns you it is powering down before it powers down, the
dialog will describe the problem (such as a fan/overtemp problem). If the
logic analysis system just powers down, it is likely a power supply
problem.
If the Power LEDs do not come on
On the 16900A, 16902A, and 16902B frames, if the lights do not come on
and if the system powers up momentarily when you plug it in, make sure
the power buttons haven't become jammed or stuck in the pushed in
position.
If you get a registry error and the system won’t boot
When powered off unexpectedly (for example, with a long press of the
power button or a power loss), Windows may not flush all system
information to disk and is vulnerable to problems. When you power back
on, you may get a "Registry Error" and the system won't boot. If this
happens you will need to restore from the system CD- ROM. In the Logic
Analysis systems with Windows 7 installation, you can restore the system
software using the recovery process. This process overwrites all the user
data and restores the system back to the original condition in which it
was shipped. Refer to the topic “On a 16900 Series Logic Analysis System
with Windows 7 Installation” on page 133 to know more about this
process.
It is best to keep regular backups of your data and use proper power
down procedures. If you have data that was not backed up that you need
to try to save:
1 Physically remove the disk drive.
2 Mount it under another Windows XP/7 system based on which
operating system is installed on the Logic Analysis system.
3 Move the data to the boot disk until you can restore the operating
system.
