Wiring procedure
The following shows the procedure for wiring Ethernet cables.
■Connection of Ethernet cables
1.
While paying attention to the connector orientation, insert the Ethernet cable connector into the Ethernet connector of
this product until a click is heard.
2.
Lightly pull on the Ethernet cable to check that it is properly connected.
3.
Make sure that the SPEED LED of the connected connector is lit green.
• The time required after the Ethernet cable is connected until the SPEED LED turns on will vary. This
normally takes several seconds. However, depending on the status of devices on the circuits, link-up
processing may repeat, requiring more time.
• If the SPEED LED does not light, check that there are no problems with the Ethernet cable.
• If Ethernet devices are connected to a network that has a communications rate of 10 Mbps, the SPEED
LED will turn off. Check communications status using PING or similar tools.
■Removal of Ethernet cables
Press and hold the clip on the Ethernet cable connector, and pull it out.
