Problems with the LAN Interface (Emulation
Probe Only)
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 emulation
probe:
❏
Make sure that you have connected the emulation probe to the proper
power source and that the power light is lit.
❏
Make sure that you wait for the power-on self test to complete before
connecting.
❏
Make sure that the LAN cable is connected. Watch the LAN LED’s to see
whether the emulation probe is seeing LAN activity. Refer to your LAN
documentation for testing connectivity.
❏
Make sure that only one of the LAN ports is connected.
❏
Make sure the emulation probe communication configuration switches are
set correctly. Unplug the emulation probe power cord, then plug it in again
to make sure the switch settings are read correctly by the emulation probe.
❏
Check that the Emulation Control Interface or debugger was configured
with the correct LAN address. If the emulation probe is on a different
subnet than the host computer, check that the gateway address is correct.
❏
Make sure that the emulation 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
emulation probe’s LAN interface with the "pv" command.
❏
It’s also possible for there to be a problem with the emulation probe
firmware while the LAN interface is still up and running. In this case, you
must reboot the emulation probe by disconnecting power to the emulation
probe and reconnecting it again.
