To execute the built-in performance verification test
Test 3: 10BaseT Feedback Test
c>pv -t3 -v2 1
Testing: HPE3499A Series Emulation System
Test # 3: LAN 10BaseT Feedback Test
PASSED Number of tests: 1
In addition to the internal checks performed in Test 2, this test also checks
for shorts on the cable connected to the network. If this test fails, disconnect
the cable and run the test again. If it then passes, the cable is faulty. If it still
fails, it requires service from HP.
If the HP processor probe passes this "pv" test, additional testing can be
performed through exercising the connection to the network. To run this
test, set configuration switch 1 and switch 5 to OPEN, all other configuration
switches CLOSED (this enables LAN using 10BaseT). Cycle power and wait
for 15 to 30 seconds. Then "ping" the HP processor probe from your host
computer or PC. See the LAN documentation for your host computer for the
location and action of the "ping" utility. If the HP processor probe fails to
respond to the "ping" request, verify that the lan parameters (IP address and
gateway address) are set correctly and that your host computer recognizes
the IP address of the HP processor probe. If all else is good, then failure to
respond to ping indicates a faulty HP processor probe.
TEST 4: Break In and Trigger Out BNC Feedback Test
c>pv -t4 -v2 1
Testing: HPE3499A Series Emulation System
Test # 4: Break In and Trigger Out BNC Feedback Test
Break In not receiving Break Out HIGH
FAILED Number of tests: 1
Before returning to HP, check to ensure that you have connected a good
Coaxial cable between the two BNCs. If the cable is good, the probe bad.
