Board Indicators

There are three LEDs on the Ethernet Controller board. The table below describes the meaning of the LED patterns for all possible states.

Table 2-1. Ethernet Controller Board Indicators

Indicator	Status	Description
MODULE OK	ON	MODULE OK is ON if the Ethernet Interface has passed
		diagnostics and its hardware is operating properly.
	OFF	It is OFF if the module fails a diagnostic test or if a fatal
		failure is detected while the board is running.
	BLINKING	This LED is blinking if the module is running
		diagnostics or is in Soft Switch Entry state.
		If this LED and the STATUS OK LED are blinking
		together, diagnostics have completed and the operator
		is being given a chance to enter Field Network Test.
ONLINE	ON	ONLINE is ON when the Ethernet Interface is
		connected to and ready to communicate on the network.
	OFF	This LED is OFF when:
		H the station is not communicating on the network
		due to disconnection or a disruption of the cable.
		H the local station has malfunctioned, or the
		Ethernet Interface has been commanded not to enter
		the network, or is in a state where network operation
		is inappropriate, such as Soft Switch Entry state or
		localloading.
	BLINKING	It is BLINKING when the module is transferringdata
		on the network or loading over the network.
STATUS OK	ON	STATUS OK is ON if the module is running without
		exceptionconditions.
	OFF	This LED is OFF if the module is running and detects an
		event that calls for supervisory attention. In this case
		you should connect the GSM and follow the instructions
		in Chapter 5 to obtain further information.
	BLINKING	This LED is BLINKING if the module is loading or look-
		ing for a load source for the Ethernet Interfacesoftware.

Restart Button

The Restart button serves two functions: Restart, and Restart and Reload. The Restart button is inaccessible when the door to the Ethernet Controller board is closed.

Restart: Pressing the Restart button (for fewer than 5 seconds) forces a restart of the Ethernet Interface. The power-up diagnostics run and the software on the module is restarted when the pushbutton is released.

Restart and Reload: Pressing and holding the Restart button for 5 seconds or more forces a restart and requests a reload of the Ethernet Interface. When the Restart button is pressed, all LEDs go out. After 5 seconds have elapsed, the STATUS OK LED comes ON, to indicate that the Ethernet Interface will request a reload. After the Restart push- button is released, the power-up diagnostics run and the Ethernet Interface requests to be loaded.
