HP E3491A, Installation And Service Manual

If you have LAN connection problems
If the Pentium probe does not accept commands from the prototype
analyzer:
1. Check that switch S1 is "0" (attached to LAN, not RS-232).
2. Check that switch S5 is in the correct position for your LAN interface
(either 10BASE2 or 10BASE-T).
(Remember: if you change any switch settings, the changes do not take effect
until you cycle power.)
If the HP E3491A Pentium Probe still does not respond, you need to
verify the IP address and gateway mask of the HP E3491A Pentium
Probe. To do this, connect the HP E3491A Pentium Probe to a terminal
or terminal emulator (see page 15), change the switch settings so it is
connected to RS-232, and enter the "lan" command. The output looks
something like this:
lan -i 15.5.24.116
lan -g 15.5.23.1
lan -p 6470
Ethernet Address : 08000909BAC1
"lan -i" shows the internet address is 15.5.24.116 in this case. If the Internet
address (IP) is not what you expect, you can change it with the ’lan -i <new
IP>’ command.
"lan -g" shows the gateway address. Make sure it is the address of your
gateway if you are connecting from another subnet, 0.0.0.0 if you are
connecting from the local subnet.
"lan -p" shows the port is 6470. If the port is not 6470, you must change it
with the "lan -p 6470" command (unless you have deliberately set the port
number to a different value because of a conflict).
If the "POL" LED is lit
The "POL" LED indicates that the polarity is reversed on the receive pair if
you are using a 10BASE-T connection. The HP E3491A Pentium Probe
should still work properly in this situation, but other LAN devices may not
work.
