2. Push the Ethernet cable connector into the IO-Link module until it clicks. Pay attention to the direction of the connector.
3. Power on the IO-Link module.
4. Power on the external device.
5. Check if the LINK LED on the port into which the Ethernet cable is connected is on.

*1 The time taken for the LINK LED to turn on after connection of the cable may vary. The LINK LED normally turns on in a few seconds.
However, if link-up processing is repeated due to a condition of a device on the line, the longer time may be required. If the LINK LED
does not turn on, refer to the following and take a corrective action.

• When the fast link-up function is not used, PORT1 and PORT2 connectors do not need to be distinguished.
When only one connector is used in star topology, either PORT1 or PORT2 can be connected. For how to
connect Ethernet cables for using the fast link-up function, refer to the following.
Page 91 Fast link-up function
• When two connectors are used in line topology or ring topology, an Ethernet cable can be connected to the
connectors in any combination. For example, the cable can be connected between PORT1s and between
PORT1 and PORT2.
■How to disconnect
1. Turn off the power supply of the IO-Link module.
2. Press the latch down and unplug the Ethernet cable.
