Step 5. Check the Network activity LED on the rear of the server. The Network activity LED is lit when data
is active on the Ethernet network. If the Network activity LED is off, make sure that the hub and
network are operating and that the correct device drivers are installed.
Step 6. Check for operating-system-specific causes of the problem, and also make sure that the operating
system drivers are installed correctly.
Step 7. Make sure that the device drivers on the client and server are using the same protocol.
If the Ethernet controller still cannot connect to the network but the hardware appears to be working, the
network administrator must investigate other possible causes of the error.
