WIRING
This chapter describes the wiring methods and wiring products for Ethernet cables, switching hubs, and optical fiber cables.
7.1

Ethernet Cables

Wire the RJ71GN11-T2 with Ethernet cables.

Wiring methods

The following describes connection and disconnection of the Ethernet cable.
Connecting the cable
1.
Push the Ethernet cable connector into P1 or P2 until it clicks, paying attention to its orientation.
2.
Lightly pull it to check that it is securely connected.
3.
Check whether the LINK LED of P1 or P2 connected with an Ethernet cable is on.
*1 The time between the cable connection and the LINK LED turning on may vary. The LINK LED usually turns on in a few seconds. Note,
however, that the time may be extended further if the link-up processing is repeated depending on the status of the device on the line. If
the LINK LED does not turn on, refer to the following and take corrective actions.
 MELSEC iQ-R CC-Link IE TSN User's Manual (Application)
Both P1 and P2 can be used.
• When only one of P1 and P2 connectors is used in a star topology, either P1 or P2 is applicable.
• When both connectors are used in a line topology, P1-P1, P2-P2, and P1-P2 connections are acceptable.
Disconnecting the cable
1.
Press the latch down and unplug the Ethernet cable.
Precautions
Be sure to follow the precautions for wiring. Otherwise, some functions may not operate normally. (It may operate normally
temporarily.)
• Place the Ethernet cable in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in
damage to the module or cables or malfunction due to poor contact.
• Do not touch the core of the cable-side or module-side connector, and protect it from dirt or dust. If oil from your hand, dirt
or dust is attached to the core, it can increase transmission loss, arising a problem in a data link.
• Check that the Ethernet cable is not disconnected or not shorted and there is no problem with the connector connection.
• Before connecting the Ethernet cables, check also the CC-Link IE TSN Installation Manual available on the CC-Link
Partner Association website (www.cc-link.org). Failure to follow the instructions in the manual may cause malfunctions.
• Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
• Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling the cable connected to the module
may result in malfunction or damage to the module or cable.
• The maximum station-to-station distance of the Ethernet cable is 100m. However, the length may be shorter depending on
the operating environment of the cable. For details, contact the manufacturer of the cable used.
• The bend radius of the Ethernet cable is limited. For details, check the specifications of the Ethernet cable to be used.
