MPC8240 and MPC8260 Emulation 145
Chapter 10: Troubleshooting the Emulator
Problems with the LAN Interface (Emulation Probe Only)
❏ Use a serial connection to run the LAN performance verification
tests (see page 141).
If you have LAN connection problems
❏ If the emulation probe does not accept commands from the
Agilent Technologies 16600A/700A:
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 emulation probe still does not respond, you need to verify the IP
address and gateway mask of the emulation probe. To do this, connect the
emulation probe to a terminal or terminal emulator (see page 41),
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 >’ command.
"lan -g" shows the gateway address. Make sure it is the address of your
gateway if you are connecting from another subnet, or 0.0.0.0 if you are
connecting from the local subnet.
"lan -p" shows the port is 6470.
