AUI Port
The AUI port provides a 10 Mbps connection only.
The following table shows the cable requirement and maximum network cable length for
the AUI port.
To connect the AUI port:
1 Locate the 15-pin AUI port on the NIC and move the slide latch down to the open position.
2 Connect the thick Ethernet coaxial cable to the AUI port on the NIC.
This connector attaches in only one way. Orient the AUI connector to match the AUI
port on the NIC.
3 Move the slide latch up to the closed position to lock the AUI connector in place.
4 Connect the other end of the network cable to an external transceiver.
The next step is to install the NIC driver. Go to “Installing the NIC Driver and Software
in Windows” on page 19 or “Installing the NetWare Server Driver” on page 27.
