5.3 Network switch troubleshooting
Problems with the network switch and possible causes and solutions are described here.
Problem Possible causes Possible solutions
No LEDs lit. No power. Check power connection to unit.
Faulty or no connection for that port. Check the cable connection for the port. Check any additional connections
(such as SeaTalk
hs crossover couplers).
Red power LED is lit but no port green
LEDs are lit.
No network activity. • Check that the unit connected to the switch is powered on.
• Check that unit connected to the switch is currently transferring data.
This can be confirmed by performing an action on the multifunction
display that will initiate data transfer for the relevant unit — for example,
if suspect a problem with the port corresponding to a connected radar
scanner, range in or out in the radar application to initiate data activity.
Slow or poor performance. Large system featuring more than one
network switch. Network switches are
connected together via a 100 Mbit/S port. Use the dedicated 1000 Mbit/S port (port 5) to connect network switches
together. You can connect a maximum of 2 switches together using a 1000
Mbit/S connection.
