RJ45 Connector J4A - J4D and J5 Pinouts
The following table indicates the pinout of the J4A - J4D and J5 connectors.
The signal pinouts on the left side of the table are for the standard Media Dependent Interface
(MDI) using appropriate CAT5 UTP cabling for the Ethernet standard in use.
The signal pinouts on the right side of the table are for the Media Dependent Interface Crossed
(MDIX) using appropriate CAT5 UTP cabling for the Ethernet standard in use.
In addition, the input / output status of each signal is also indicated in the table.
2.5.1.1
Ethernet LED Status
ACT (green): This LED monitors network connection and activity. The LED lights up when a
network link is established and blinks when packets are sent or received through the RJ45 port.
When this LED is not lit, it means that either the link is not present or the cable connection is
faulty.
SPEED (green/yellow): This LED lights up to indicate a successful 100Base-TX or
1000BASE-T connection. When green it indicates a 100Base-TX connection and when yellow
it indicates a 1000Base-T connection. When not lit and the ACT LED is active, the connection
is operating at 10Base-T.
