Introduction

15-Pin Connector

The standard 15-pin connector on the other end of the BayStack 22 PC Card Adopter (Figure 1-1) attaches to the 15-slot connector on the media coupler.

Media Coupler

The media coupler (Figure 1-2) provides connection to the BayStack 22 PC Card Adopter and to Ethernet network devices. Three LEDs located on the media coupler indicate 10 Mb/s or 100 Mb/s transmission speed and connection stability.

The 15-slot connector on the media coupler attaches to the 15-pin connector on the BayStack 22 PC Card Adopter. The other end of the media coupler contains an RJ-45 port. You can attach a standard Ethernet cable to the RJ-45 port to connect the network card to a network device such as a hub or switch.

RJ-45 Ethernet Port

The RJ-45 10BASE-T/100BASE-TX Ethernet 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.
