2. Interfaccia utente

Tutte le funzioni del WebGate possono essere controllate utilizzando
pagine HTML o una interfaccia consolle RS232. Vi sono comunque tre
LED multicolore e un pulsante di “reset” per semplificare l’installazione.

2.1 LED

2.1.1 Ethernet

Il LED in alto fornisce informazioni sulla connessione Ethernet.

Funzionamento normale

Durante il funzionamento normale, il comportamento del LED è quello
indicato in tabella:

Colore

Significato

Spento

Collegamento (Link), nessun trasferimento 
di dati in corso.

Verde (lampeggiante)

Collegamento, trasferimento dati in corso.

Giallo

Nessun collegamento, il WebGate sta 
tentando una trasmissione.

Rosso

Nessun collegamento. Generalmente indica 
che un cavo è scollegato, un cablaggio è 
scorretto o l’interfaccia remota (generalmente
un PC o un hub) è spenta.

Tab. 2.1.1.1

Accensione:

Durante la fase di accensione, il LED Ethernet diventa rosso per alcuni
secondi fino a quando l’interfaccia non è inizializzata.

2. User Interface

All WebGate functions can be controlled using HTML pages or RS232
console interface. However, three multicolor LEDs and a “reset” button
are provided to simplify installation.

2.1 LED

2.1.1 Ethernet

The top LED gives information about the Ethernet link and connection.

Normal behaviour

The normal LED behaviour is indicated in the table below:

Color

Meaning

Off

Connected (Link), no data transfer in 
progress.

Green (flashing)

Link, data transfer in progress.

Yellow

No link, WebGate is trying a transmission.

Red

No link. Generally this indicates disconnected
cable, wrong cabling or remote interface 
(generally a PC or a hub) powered off.

Tab. 2.1.1.1

Power up:

When WebGate is powered up, the Ethernet LED becomes red for
some seconds until the interface is properly initialized.
