HP E3494A Installation And Service Manual page 21

Once you have set a valid IP address, you can use the telnet utility to connect
to the HP processor probe, and use the lan command to change LAN
parameters.
Example
For example, to assign an IP address of 192.6.94.2 to the HP processor probe,
enter the following command:
R>lan -i 192.6.94.2
The IP address and any other LAN parameters you change are stored in
nonvolatile memory and will take effect the next time the HP processor probe
is powered off and back on again.
