Suggested Action
Check the following:
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.
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.
Check the following:
• Make sure that the cable is
connected to the Ethernet controller.
• Make sure that the PCI system BIOS
is current.
• Reseat the adapter.
• 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.
Check the following:
• Run diagnostics for the Ethernet
controller.
• Try a different connector on the hub.
• Reinstall the device drivers. Refer to
the operating-system documentation
and to the ServerGuide information.
