Check to see that the port under test has a good cable connected to it
and that the cable is properly terminated with a 50 ohm terminator on
each end of the overall cable.
R>pv -t2 -v2 1
Testing: HPE3499B Series Emulation System
Test # 2: LAN 10Base2 Feedback Test
FAILED due to excessive collisions
FAILED Number of tests: 1
The most common cause of this problem is poor termination of the
cable or failure to remove the port under test from the LAN before
performing the test. Check to see that the terminators are good (50
ohms) and that you are isolated from any traffic on a system LAN.
R>pv -t2 -v2 1
Testing: HPE3499B Series Emulation System
Test # 2: LAN 10Base2 Feedback Test
FAILED - invalid Ethernet address in EEPROM
FAILED Number of tests: 1
First check to see that a correct link-level address and IP address have
been set in the virtual EEPROM through the "lan" command. If the
"lan" command shows bad information for the link-level address and IP,
then try to set them to correct values. If you are unable to set them to
correct values, their is a failure in the FLASH ROM which requires
service from HP.
Test 3: 10BaseT Feedback Test failed here
R>pv -t3 -v2 1
Testing: HPE3499B Series Emulation System
Test # 3: LAN 10BaseT Feedback Test
FAILED 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 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 emulator
from your host computer or PC. See the LAN documentation for your
