time if there is hardware malfunction of the Lisa.
Press OK to start the selftest. The device will shut down after a
few seconds. If there is no problems with your hardware the
Selftest should return PASS. Enter the [Service] menu again
and look at the result in [R-Selftest].
5.3
Connection test
When installing Lisa devices in a specific network, it is important that the device is properly configured to
work in this network. The minimum requirements for this is that the IP configurations are correct. But,
correct IP configurations are not always sufficient for the device to function properly. E.g. when a firewall
is used, then it is required that traffic from and to the Lisa is allowed on specific ports etc.
To verify that the various connections can actually be made, the Lisa can perform a connection test.
