Solving Ethernet controller problems
The method that you use to test the Ethernet controller depends on which operating
system you are using. Check the operating-system documentation for information
about Ethernet controllers, and see the Ethernet controller device driver readme file.
Make sure that the latest device drivers are installed.
If the problem remains after you check these factors, try the following procedures:
v Make sure that the Ethernet cable is installed correctly.
The cable must be securely attached at all connections. If the cable is
attached but the problem remains, try a different cable.
If you set the Ethernet controller to operate at 100 Mbps, you must use
Category 5 cabling.
If you directly connect two servers (without a hub), or if you are not using a
hub with X ports, use a crossover cable. 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 whether the hub supports auto-negotiation. If it does not, try
configuring the integrated Ethernet controller manually to match the speed and
duplex mode of the hub.
v Check the Ethernet controller LEDs on the rear panel of the server. These LEDs
indicate whether there is a problem with the connector, cable, or hub.
The Ethernet link status LED is lit when the Ethernet controller receives a link
pulse from the hub. If the LED is off, there might be a defective connector or
cable or a problem with the hub.
The Ethernet transmit/receive activity LED is lit when the Ethernet controller
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 installed.
v Check the LAN activity LED on the rear of the server. The LAN activity LED is lit
when data is active on the Ethernet network. If the LAN activity LED is off, make
sure that the hub and network are operating and that the correct device drivers
are installed.
v Make sure that you are using the correct device drivers, which come with the
server.
v Check for operating-system-specific causes for the problem.
v 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
sources of the error.
