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.
v Determine if the hub supports auto-negotiation. If not, try configuring the
v Check the Ethernet adapter lights on the operator information panel.
v Make sure that you are using the correct device drivers, supplied with the NAS
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
v Test the Ethernet adapter by running the diagnostic program.

NAS 200 User's Reference
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.
integrated Ethernet adapter manually to match the speed and duplex mode of the
hub.
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.
