4.4.9 Wink Action
If the L-IP receives a wink command on any of its network ports, it shows a blink pattern on
the CNIP and the CEA-709 activity LEDs. The CEA-709 activity and the CNIP LED turn
green/orange/red (each 0.15 s). This pattern is repeated six times. After that the CNIP LED
flashes orange six times if the wink command was received on the IP channel or the
CEA-709 activity LED flashes orange six times if the wink command was received on the
CEA-709 channel. After that the L-IP LEDs return to their normal behavior.
4.4.10 Network Diagnostics
The L-IP provides simple network diagnostics via its CEA-709 activity LED:
If the LED does not light up at all this port is not connected to any network segment or
the connected network segment currently shows no traffic.
If the LED is flashing green the network segment connected to this port is ok.
If the LED is flashing red a potential problem exists on the network segment connected
to this port. This state is referred to as overload condition.
A port overload condition occurs if
the average bandwidth utilization of this port was higher than 70% or
the collision rate was higher than 5% or
more than 15% CRC errors have occurred on a port with a power-line transceiver or
more than 5% on a port with a transceiver other than power-line or
the L-IP was not able to process all available messages.
the L-IP Redundant has detected an open loop (L-IP Redundant only, see Section 9).
For a deeper analysis of the reason of the overload condition it is recommended to use a
protocol analyzer (e.g. LOYTEC’s LPA) or a similar tool. The exact reason of the overload
condition can also be determined with the LSD Tool (see Chapter 14).
4.5 Status Button
The L-IP is equipped with a status button (see installation sheet). When pressing the status
button shortly during normal operation of the L-IP it sends a “Service Pin Message” on all
network ports. Note that every L-IP port has its own unique node ID (“Neuron ID”). As
alternative to pressing the status button a service pin message can be sent via the web
interface (see Section 6.1).
Pressing the status button longer than 2 seconds will allow you to select the port to sends
out the “Service Pin Message” message: The port LED of the currently selected port will
light up orange. After 2 seconds the next available port will be selected. When the status
button is released the “Service Pin Message” is sent out on the currently selected port.
Pressing the status button during normal operation for more than 20 seconds resets the
switching tables (see Section 4.5.1).
4.5.1 Resetting Forwarding Tables
In order to reset the forwarding tables, the status button needs to be pressed for at least 20
seconds during normal operation of the L-IP. Resetting forwarding tables defaults means:
