8 Troubleshooting the ParBERT Installation Problems after Changing the Hardware
8-2 Agilent 81250 ParBERT Installation Guide, May 2004
Problems after Changing the
Hardware
Check the following points if you have modified the hardware and are
experiencing problems:
Problem:
The green Access LED of a module lights up, apparently without any
reaction.
Solution:
This is due to an internal update of the reconfigurable logic circuitry. Do
not power down unless all green LEDs are off. Wait at least 12 minutes
before switching the mainframe off.
Problem:
ParBERT does not recognize newly inserted modules, or the modules are
not in any easy-to-follow order.
Solution:
Have you rebuilt the systems?
Check the detected configuration with the Agilent 81250 Configuration
tool.
Any time you change the system configuration, you have to make sure
that the correct logical addresses are used. See
“How to Set the Logical
Address” on page 6-5 .
Ensure also that the modules are correctly plugged into the VXI frame.
The front panels of all modules together must form a plane, uniform
surface. Tighten the arresting screws.
