Ethernet Controller Troubleshooting Chart - Netfinity 5600 - Type 8664

Ethernet Controller Troubleshooting Chart:

You can use the following troubleshooting chart to find solutions to 10/100 Mbps Ethernet controller problems that have definite symptoms.

loading device drivers.	Check the following:
	° Determine if the interrupt (IRQ) setting 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.
	° Make sure that you are using the most recent device driver
	available from the World Wide Web.
	(Refer to the 'Getting Help Information' section of this
	Server Library for World Wide Web addresses.)
	° Run the network diagnostic program.
	If the problem still exists, have the system serviced.
Ethernet Link Status light	Check the following:
does not light.	° Make sure that the hub is turned on.
	° Check all connections at the Ethernet controller and the hub.
	° Check the cable. A crossover cable is required unless the hub
	has an X designation.
	° Use another port on the hub.
	° If the hub does not support auto-negotiation, manually
	configure the Ethernet controller to match the hub.
	° If you manually configured the duplex mode, make sure that
	you also manually configure the speed.
	° Run diagnostics for the LEDs.
	If the problem still exists, have the system serviced.
The Ethernet Transmit/Receive	Check the following:
Activity light does not light.	Note:
	The Ethernet Transmit/Receive Activity LED illuminates only
	when data is sent to or by this Ethernet controller.
	° Make sure that you have loaded the network device drivers.
	° The network might be idle. Try sending data from this workstation.
	° Run diagnostics on the LEDs.
	° The function of this LED can be changed by device driver load
	parameters. If necessary, remove any LED parameter settings
	when you load the device drivers.
Data is incorrect or sporadic.	Check the following:
	° Make sure that you are using Category 5 cabling when operating
	the server at 100 Mbps.
	° Make sure that the cables do not run close to noise-inducing
	sources like fluorescent lights.
The Ethernet controller	Check the following:

adapter was added to the server.	° Make sure that the PCI system BIOS is current.
	° Reseat the adapter (see 'Working with adapters').
	° Determine if the interrupt (IRQ) setting assigned to the
	Ethernet adapter 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 adapter or the
	other device.
	If the problem still exists, have the system serviced.
The Ethernet controller stopped	Check the following:
working without apparent cause.	° Run diagnostics for the Ethernet controller.
	° Try a different connector on the hub.
	° Reinstall the device drivers.
