Cannot Connect to a Server
• Make sure the network cable is securely attached to the correct connector at the
system back panel.
• Try a different network cable.
• Make sure you are using the correct and the current drivers. See “Server System
References” on page xix for a link to the current drivers.
• Make sure the driver is loaded and the protocols are bound.
• Make sure the hub port is configured for the same duplex mode as the network
controller.
• Make sure the correct networking software is installed.
• If you are directly connecting two servers (without a hub), you will need a crossover
cable.
• Check the network controller LEDs next to the NIC connectors.
