RJ-45 Ethernet Port

The RJ-45 10BASE-T/100BASE-TX Ethernet port connects the network card to a

network device, such as a hub. The port adapts to the correct network speed of

10 Mb/s or 100 Mb/s through autonegotiation with the board components of the

network card. The port is wired as an MDI-X port to connect to other devices

without using a crossover cable.

LEDs

The front of the BayStack 21 network card contains three LEDs (Figure 1-1

Figure 1-1. Link and Activity LEDs

The 10 Mb/s and 100 Mb/s Link LEDs indicate successful network connections to

Ethernet and Fast Ethernet devices, respectively. The Link LEDs remain steady if

the connection is stable. You should check the RJ-45 connection if the LED is not

steady. The Activity LED indicates active network traffic.
