Ethernet
controller
problem Suggested Action
Ethernet Link
Status light does
not light. Check the following:
v
Make sure that the hub is turned on.
v Check all connections at the Ethernet
controller and the hub.
v Check the cable. A crossover cable is
required unless the hub has an
X
designation.
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
Run diagnostics on the LEDs.
The Ethernet
Transmit/Receive
Activity light
does not light. Check the following:
Note: The Ethernet Transmit/Receive Activity
LED illuminates only when data is sent to or by
this Ethernet controller.
v Make sure that you have loaded the network
device drivers.
v The network might be idle. Try sending data
from this workstation.
v
Run diagnostics on the LEDs.
v 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:
v Make sure that you are using Category 5
cabling when operating the server at 100
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. Check the following:
v Make sure that the cable is connected to the
Ethernet controller.
v Make sure that your PCI system BIOS is
current.
v Reseat the adapter.
v 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.
