Chapter 5 Troubleshooting the System Hardware

Troubleshooting the Ethernet Controller

Note The following are the minimum operating requirements:

One power supply

Power cage assembly

System board

One microprocessor and voltage regulator module (VRM)

Memory module (with a minimum of two 128-MB DIMMs)

Troubleshooting the Ethernet Controller

This section provides troubleshooting information for problems that might occur with the 10/100/1000-Mbps Ethernet controller.

Network Connection Problems

If the Ethernet controller cannot connect to the network, check the following conditions:

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 remains, try a different cable.

If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps, you must use Category 5 or higher cabling.

Determine whether the hub supports autonegotiation. If it does not, try configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub.

Check the Ethernet controller LEDs on the device back panel. (See Figure 1-3.)
