2.4. RJ45 Ports – Signal Description
2.4.1. 10/100 TX Port
10/100Base-TX ports allow connection to standard CAT-5E STP (shielded twisted pair) cable with
RJ45 male connectors. The RJ45 receptacles are directly connected to the chassis ground on the
unit and can accept CAT-5E STP (shielded twisted pair) cables. When shielded cables are used,
care must be taken to ensure that a ground loop is not formed via the shield wire and the RJ45
receptacles at either end.
Figure 2.4, “RJ45 Port Pinout” shows the RJ45 port pinout.
