v Test the Ethernet controller. The way the Ethernet controller is tested depends on which operating system you are using (see the Ethernet controller device driver readme files). Ethernet controller troubleshooting chart Use the following troubleshooting chart to find solutions to 10/100/1000 Mbps Ethernet controller problems that have definite symptoms. Ethernet controller problem FRU/actions The server stops running when loading device drivers. The PCI BIOS interrupt settings are incorrect. v Determine whether the interrupt (IRQ) setting that is assigned to the Ethernet controller is also assigned to another device in the Configuration/Setup Utility program. Although interrupt sharing is allowed for PCI devices, some devices do not function well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet controller or the other device. For example, for NetWare Versions 3 and 4, it is recommended that disk controllers not share interrupts with LAN controllers. v Make sure that you are using the most recent device driver that is available from the World Wide Web. v Reseat or replace the adapter. The Ethernet link status v Make sure that the hub is turned on. LED does not work. v Check all connections at the Ethernet controller and the hub. v Use another port on the hub. v If the hub does not support auto-negotiation, manually configure the Ethernet controller to match the hub. v If you manually configured the Duplex mode, make sure that you also manually configure the speed. v Reseat or replace the adapter. The Ethernet v Make sure that you have installed the network device drivers. transmit/receive activity v The network might be idle. Try sending data from this server. LED does not work. Data is incorrect or sporadic. v Make sure that you are using Category 5 or higher cabling when operating the server at 100 Mbps or at 1000 Mbps. v Make sure that the cables do not run close to noise-inducing sources like fluorescent lights. The Ethernet controller stopped working when another adapter was added to the server. v Make sure that the cable is connected to the Ethernet controller. v Make sure that the PCI system BIOS code is current. v Reseat the adapter. v Determine whether the interrupt (IRQ) setting that is assigned to the Ethernet adapter is also assigned to another device in the system. Use the Configuration/Setup Utility program to determine whether this is the case. Although interrupt sharing is allowed for PCI devices, some devices do not function well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ that is assigned to the Ethernet adapter or the other device. v Reseat or replace the adapter.
