If You Have Lan Connection Problems - HP E3473A User Manual

Solving Problems

If you have LAN connection problems

It's possible that the host software is in the process of running a
command. You can use <CTRL>c to interrupt and get the Terminal
Interface prompt.
It's also possible for there to be a problem with the HP E3472A/73A
Emulator firmware while the LAN interface is still up and running. In
this case, you must reboot the HP E3472A/73A Emulator by
disconnecting power to the HP E3472A/73A Emulator and reconnecting
it again.
If you have LAN connection problems
Try to "ping" the HP E3472A/73A Emulator. At your operating system
prompt, type:
ping <hostname or IP address>
If it does not respond:
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 E3472A/73A Emulator still does not respond to a "ping", you
need to verify the IP address and gateway mask of the HP E3472A/73A
Emulator. To do this, connect the HP E3472A/73A Emulator to a
terminal or terminal emulator (see page 34), 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.
