Troubleshooting Tips for Suspected GTX Transformer Failure

Typical customer complaint: a burning smell followed by a system error pop up during applications boot
up.
If this occurs, avoid any further live scanning, as probe damage can occur.
NOTE: DO NOT introduce additional probes onto the system until diagnostics have been successfully
run.
Remove GTX Boards one at a time and perform a visual inspection. Make sure to label the boards to
reflect which slot each board was removed from. Remember to install the GTX Boards back in their
original locations throughout the troubleshooting process.
Perform visual inspection of the diodes on the upper and lower Front Planes. Make sure to label the
Front Planes to reflect which is the upper and which is the lower. Remember to install the Front Planes
back in their original locations throughout the troubleshooting process.
