VCI MODULE DIAGNOSTIC CHART<br />
Test Results Solution<br />
GND FET<br />
(Ground Field Effect<br />
Transistor)<br />
VCI HBCC<br />
(Hosted Bus Control Chip)<br />
VCI DUART<br />
(Dual Universal Asynchronous<br />
Receiver Transmitter)<br />
VCI I/O 1 - I/O 16 Test<br />
VCI loopback<br />
VCI short L & M<br />
GND FET - pass/fail<br />
HBCC - pass/fail<br />
Channel A - pass/fail<br />
Channel B - pass/fail<br />
Pass/fail messages will be displayed for<br />
each of the I/O lines (results from selectable<br />
VCI test).<br />
If test fails, was loopback installed?<br />
Pass/fail message for each I/O loopback<br />
test.<br />
Open I/O 7 - pass/fail<br />
Open I/O 9 - pass/fail<br />
Hi I/O 7 - pass/fail<br />
Hi I/O 9 - pass/fail<br />
Lo I/O 7 - pass/fail<br />
Lo I/O 9 - pass/fail<br />
Check loopback adapter to make sure it is connected,<br />
cycle <strong>Tech</strong> 2 retest.<br />
If problem persists, contact Customer Support.<br />
If HBCC chip fails, cycle <strong>Tech</strong> 2 and retest.<br />
If problem persists, contact Customer Support.<br />
If channel A or channel B fail, cycle <strong>Tech</strong> 2 and retest.<br />
If problem persists, contact Customer Support.<br />
Once an error has been detected on one of the I/O<br />
lines, you can test the specific line by selecting F3 or F4<br />
tests. If the test fails continuously or intermittently,<br />
contact Customer Support.<br />
For any failure, make sure the loopback is connected.<br />
Use F1: Check ID to verify that the loopback is found.<br />
Cycle <strong>Tech</strong> 2 and retest. If problem persists, contact<br />
Customer Support.<br />
For any failure, cycle <strong>Tech</strong> 2 and retest.<br />
If problem persists, contact Customer Support.<br />
