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:

vMake 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.

vDetermine 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.

vCheck 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.

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

vCheck for operating system-specific causes for the problem.

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

vTest the Ethernet adapter by running the diagnostic program.
