Integrated Ethernet adapter

This section provides troubleshooting information for problems that might occur with
the 10/100 Mbps integrated Ethernet adapter.

Network connection problems

If the Ethernet adapter cannot connect to the network, check the following:

v

Make sure that the cable is installed correctly.

The network cable must be securely attached at all connections. If the cable is
attached but the problem persists, try a different cable.

If you set the Ethernet adapter to operate at 100 Mbps, you must use Category 5
cabling.

If you directly connect two workstations (without a hub), or if you are not using a
hub with X ports, use a crossover cable.

Note: To determine whether a hub has an X port, check the port label. If the

label contains an X, the hub has an X port.

v

Determine if the hub supports auto-negotiation. If not, try configuring the
integrated Ethernet adapter manually to match the speed and duplex mode of the
hub.

v

Check the Ethernet adapter lights on the operator information panel.

These lights indicate whether a problem exists with the connector, cable, or hub.
– The Ethernet Link Status light is On when the Ethernet adapter receives a

LINK pulse from the hub. If the light is Off, there might be a bad connector or
cable, or a problem with the hub.

– The Ethernet Transmit/Receive Activity light is On when the Ethernet adapter

sends or receives data over the Ethernet Network. If the Ethernet
Transmit/Receive Activity light is Off, make sure that the hub and network are
operating and that the correct device drivers are loaded.

v

Make sure that you are using the correct device drivers, supplied with the NAS
200 engine.

v

Check for operating system-specific causes for the problem.

v

Make sure that the device drivers on the client and the NAS 200 engine are
using the same protocol.

v

Test the Ethernet adapter by running the diagnostic program.
