Notes
When connecting the LAN connector to the network that includes the host machine, keep the
following points in mind:
Turn off the power before connecting or removing a cable. While the power is turned on,
connecting or removing a cable may cause a malfunction.
To remove a cable, do not pull the cable itself; grasp and pull the connector. Pulling the
cable itself may cause a conductor inside the cable to break.
