device drivers.
	• 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.
	• Run the network diagnostic program.
	If the problem remains, call for service.

	• 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.
