HAPTER
The Fast EtherLink EISA adapter uses an on-board transceiver
with twisted-pair cable. To establish a valid 10 Mbps
connection, the cable must be connected to a 10BASE-T hub.
To establish a valid 100 Mbps connection, the cable must be
connected to a 100BASE-TX hub. Connect the network cable
as follows:
1 Make sure that the connector on your cable is wired
appropriately for standard 10BASE-T or 100BASE-TX
adapter cards.
The UTP wire pairs and pin definitions for 100BASE-TX are
identical to those for 10BASE-T when used with Category 5
UTP cable. The "straight-through" connection should be made
from the Fast EtherLink EISA adapter through the cable and
connectors to the hub. No crossover in the cable is required.
Refer to Figure A-1 for RJ-45 connector pin assignments.
2 Align the RJ-45 connector on the end of the twisted-pair
cable with the notch on the adapter's RJ-45 port and
insert it into the RJ-45 port.
The next step is to configure the adapter with the EISA
configuration utility and the EtherDisk diskette configuration
file. This is explained in Chapter 3, "Configuring the Adapter."
If you are running Windows 95, you can confirm the network
connection by double-clicking the Network Neighborhood
icon. The presence of the Entire Network icon in the display
box confirms the network connection.
