Problems With The Lan Interface; If You Cannot Verify Lan Communication - Agilent Technologies E5900B User Manual

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 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.
❏ 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. To do
this, connect the emulation probe to a terminal or terminal emulator and
enter the lan command. (See "To configure LAN parameters using a serial
connection" on page 30.)
❏ Make sure that the gateway address is set up correctly. The default
gateway address of 0.0.0.0 does not allow the emulation probe to
communicate with computers on other subnets.
❏ If you have just changed the IP address of the emulation probe, leave the
emulation probe powered on and connected to the LAN for a few minutes,
then try again. Some hubs, routers, and hosts maintain tables of IP
addresses and link-level addresses. It may take a while for these tables to
be updated.
❏ Make sure that the proper LAN cable is connected.
• Use a Category 5 cable if your connection is running at 100 Mbps
(100BASE-TX).
• For a point-to-point connection, use a crossover cable.
• For a LAN connection, use a regular LAN cable, not a crossover cable
(the cable supplied with the emulation module, part number 5061-
7342, is a crossover cable).
