3. Starting the clock and setting the time

Since the network socket (RJ45) is connected to the clock, you can check that the clock is
correctly connected to the network using the two LEDs located on either side of the Ethernet
socket.
- Constant green LED (left): connection established with a network,
- Flashing yellow LED (right): activity, data being sent and received.
RJ45 Ethernet port: Single-sided (left) and Double-sided (right)
When powering up the clock, the hands are positioned at midday until a time signal is received.
After validation of the NTP synchronisation data, the clock sets itself to the correct time
automatically. Movement of the hand may start up to three minutes after setting the time of the clock
via the web server.
Time synchronisation is carried out via an NTP server (three modes are possible):
- Address(es) provided by DHCP server,
- Unicast NTP server (up to five different addresses),
- Multicast server (one address).
Factory settings may be restored via the web server.
In the event of an anomaly, the behaviour of your clock differs depending on the model and
whether or not it has a back-up battery.
Mains NTP model without battery:
If the mains power supply cuts out, the lighting (if this option has been selected) goes off and the
hands stop moving. When the power is restored, the hands return to the midday position.
The clock then resynchronises the time and the lighting comes back on.
Mains NTP model with battery:
If the mains power supply cuts out, the second hand stops moving and the lighting (if this option
has been selected) goes off. The hour and minute hands continue to work for an hour, powered by
the battery. If the mains power supply is not restored, all the hands stop. They return to the midday
position when the power is restored. The clock then resynchronises the time and the lighting comes
back on.
NTP PoE model without battery:
If the mains power supply cuts out, the lighting (if this option has been selected) goes off. All the
hands continue to work because power is supplied to the circuit board by the PoE network.
However, if the PoE network also cuts out, all the hands stop. They return to the midday position
when the PoE network is restored. The clock then resynchronises the time. The lighting comes back
on when the mains power supply is restored.
