LOGIQ E9 GTX HV (High Voltage) Failure on MRX Systems (cont'd)
NOTE:
Use "FatalHW" as a search string to find error in the error log. This will help to identify the error
explained in step 2 and narrow down to the board that is causing it.
GTX "numbers" use 1, 2, 3 and 4 as nomenclature in VPD, but 0 (zero), 1, 2 and 3 are used as
nomenclature in diagnostics. In this manual, 1, 2, 3 and 4 nomenclature is used to identify board, based
on location in the Card Rack. See: Figure 7-201 "Card Rack - GTX Board Location (MRX Configuration)"
on page 7-336.
2.) Error log: The logfile.txt will display an entry like the following:

As the log indicates, the GTX3 was generating the error.
How to Fix:
The board needs to be replaced with the Rev. D or later, to prevent this error from reccurring.
The Rev. D Boards have been terminated correctly to prevent floating voltages.
NOTE:
Label the GTX Boards prior to removal to reflect which slot each board was removed from, if
replacing one or two boards. Install the boards back in the original locations.
Label the Front Planes prior to removal to reflect which is the upper and which is the lower. Install the
Front Planes back in the original locations.
Service Stock of the GTX Boards have been purged and populated with Rev. D or later.
NOTE:
GFI console models do not have this problem because those signals are terminated correctly
in the Backplanes for GFI console models.
