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.
