Description of Self Test Items C-17
Test Content
Check whether TRA is in the place, and then read the slot ID of TR64 board (the slot ID can be set
via the mother board).
Analysis to Test Failure
The drive goes wrong if the test result appears Error.
The error for slot ID of TRA board occurs if the test result is FAIL.
Suggestion to Test Failure
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device if Error re-appears.
If the test result is FAIL, replace the TRA first, and then replace the engine board.
C.1.39 Z1402 TRA XCVR Bus Test
Top test item
TRA Slot ID Test,PC Module and DSP FPGA Interconnection Test
Test Content
Test whether the control bus communication between DSP FPGA and XCVER of TRA FPGA
works well via reading the register.
Analysis to Test Failure
The drive goes wrong if the test result appears Error.
The connection error between DSP FPGA and TRA FPGA occurs if the test result is FAIL.
Suggestion to Test Failure
a) Restart the device to perform the self test if the test result appears Error. It is necessary to
restore the device if Error re-appears.
b) It is recommended to change TRA board if the test result is FAIL.
C.1.40 Z1403 TRA DDRIII (DIMM) Test
Top test item
TRA XCVR Bus Test
Test Content
Read and write on the memory of the TRA and judge whether the data for the write and the input
are the same.
Analysis to Test Failure
The drive goes wrong if the test result appears Error.
The connection error between FPGA and the memory occurs if the test result is FAIL.
Suggestion to Test Failure
a) Restart the device to perform the self test if the test result appears Error. It is necessary to
restore the device if Error re-appears.
b) If the test result is FAIL, it is recommended to check the TRA on the engine board.
