Introduction

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.
