C-18 Description of Self Test Items
C.1.41 Z1501 TRB Slot ID Test
Top test item
TRA Slot ID Test
Te s t Content
Check whether TRB is in the place, and then read the slot ID of TRB board (the slot ID of TR64
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 TRB 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 TRB first, and then replace the engine board.
C.1.42 Z1402 TRB XCVR Bus Test
Top test item
TRB Slot ID Test,PC Module and DSP FPGA Interconnection Test
Test Content
Test whether the control bus communication between DSP FPGA and XCVR of TRB 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 TRB 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 TRB board if the test result is FAIL.
C.1.43 Z1503 TRB DDRIII (DIMM) Test
Top test item
TRB XCVR Bus Test
Test Content
Read and write on the memory of the TRB 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
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 TRB on the engine board.
