Solving Problems
To execute the built-in performance verification test
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 E3472A/73A Emulator 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 E3472A/73A Emulator 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 E3472A/73A
Emulator 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 E3472A/73A Emulator. If all
else is good, then failure to respond to ping indicates a faulty HP E3472A/73A
Emulator.
TEST 4: Break In and Trigger Out BNC Feedback Test
R>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
HP E3472A/73A Emulator is bad.
TEST 5: Target Probe Feedback Test
A verbose output on this test can be extensive. For example, the following is
the output of this test if you forget to plug in the E3496-66502 loop-back
board.
p>pv -t5 -v2 1
Testing: HPE3499A Series Emulation System
