The operator must correct the fault forcing entry into this state before the Ethernet Interface may proceed. In most cases this may be done by using the Logicmaster 90-70 Configurator or the Station Manager CHSOSW command. It cannot be performed remotely from the network. After entering new Soft Switch information or correcting another fault, the Ethernet Interface must be restarted to begin using these new values.

In the Soft Switch Entry state, a NODE command to the Station Manager will yield a ªSoft Switch Entry Utilityº message following the station identification information; also, the Station Manager prompt is an asterisk (ª*º).

The Field Network Test State

The Field Network Test state is selected by entering a ªFº or ªfº in response to the ª@º prompt at the local Station Manager terminal at the end of power-up diagnostics. The ªfº will not be echoed back. A limited subset of Station Manager commands is provided in this state. Refer to Chapter 5, ªField Network Test Utilityº for a detailed description of the Field Network Test state and to Chapter 2, ªInstallation Procedure 5 - Testing the Ethernet Interfaces on the Networkº for an application. The table below shows the LED patterns for Field Network Test State.

In the Field Network Test State, a NODE command to the Station Manager will indicate ªField Network Test Utilityº. The Station Manager prompt is a dollar sign (ª$º).
