Problems with the LAN Interface
If you cannot verify LAN communication
If you cannot verify connection using the procedure in "To verify LAN
communication", or if the commands are not accepted by the Pentium probe:
Make sure that you have connected the HP E3491A Pentium Probe to
the proper power source and that the power light is lit.
Make sure that the LAN cable is connected. Refer to your LAN
documentation for testing connectivity.
Make sure that only one of the LAN ports is connected.
Make sure the HP E3491A Pentium Probe communication configuration
switches are set correctly. Unplug the HP E3491A Pentium Probe power
cord, then plug it in again to make sure the switch settings are read
correctly by the HP E3491A Pentium Probe.
Make sure that the HP E3491A Pentium Probe's IP address is set up
correctly. Use the RS-232 port to verify this that the IP address is set up
correctly. When you are connected to the RS-232 port, run performance
verification on the HP E3491A Pentium Probe's LAN interface with the
"pv" command.
It's also possible for there to be a problem with the HP E3491A Pentium
Probe firmware while the LAN interface is still up and running. In this
case, you must reboot the HP E3491A Pentium Probe by disconnecting
power to the HP E3491A Pentium Probe and reconnecting it again.
