Problems and Solutions
Diagnostics pass, but the connection fails or
errors occur.
1. At 100Mbps, use Category 5 wiring and make sure the network cable is
securely connected.
2. For NetWare clients, make sure that you specify the correct frame type
in your NET.CFG file.
3. Make sure that the duplex mode setting on the NIC matches the setting
on the hub.
4. At 100Mbps, connect to a 100BASE-TX hub only (not 100BASE-T4).
5. The NIC device driver may be faulty. Re-install the driver and check the
connection.
6. The Unit IP address does not match the network subnet mask that it is
connected to.
7. The NIC "software" MAC address already corresponds to an existing
MAC address out on the network.
8. TCP/IP protocol is not installed to the network stack yet.
9. The NIC set up for DHCP cannot talk to the DHCP server. The user
needs to use a static IP address.
The LNK LED does not light.
1. Check all connections at the NIC and the hub.
2. Try another port on the hub.
3. Make sure the duplex mode setting on the NIC matches the setting on
the hub.
4. Make sure that you have the correct type of cable between the NIC and
the hub. 100BASE-TX requires two pairs. Some hubs require a
crossover cable, and others require a straight-through cable. Refer to the
"Cabling Information" Readme file for more information on cabling.
