Problem
Solution
The Link indicator light is off
Run the adapter and network tests described under "Test
the Adapter".
Make sure the proper (and latest) driver is loaded.
Make sure that the link partner is configured to auto-
negotiate (or forced to match adapter)
Verify that the switch is IEEE 802.3ad-compliant.
The link light is on, but communications are
not properly established
Make sure the proper (and latest) driver is loaded.
Both the adapter and its link partner must be set to either
auto-detect or manually set to the same speed and duplex
settings.
NOTE:
The adapter's link indicator light may
be on even if communications between the
adapter and its link partner have not been
properly established. Technically, the link
indicator light represents the presence of a
carrier signal but not necessarily the ability to
properly communicate with a link partner.
This is expected behavior and is consistent
with IEEE's specification for physical layer
operation.
RX or TX light is off
Network may be idle; try creating traffic while monitoring
the lights.
The diagnostic utility reports the adapter is
"Not enabled by BIOS"
The PCI BIOS isn't configuring the adapter correctly. See
PCI / PCI-X / PCI Express Configuration.
The computer hangs when the drivers are
loaded
Try changing the PCI BIOS interrupt settings. See PCI /
PCI-X / PCI Express Configuration.
The Fan Fail LED of the 10 Gigabit AT
Server Adapter is on (red)
The fan cooling solution is not functioning properly.

Multiple Adapters
When configuring a multi-adapter environment, you must upgrade all Intel adapters in the computer to the
latest software.
If the computer has trouble detecting all adapters, consider the following:
l
If you enable Wake on LAN* (WoL) on more than two adapters, the Wake on LAN feature may over-
draw your system’s auxiliary power supply, resulting in the inability to boot the system and other unpre-
dictable problems. For multiple desktop/management adapters, it is recommended that you install one
adapter at a time and use the IBAUtil utility (ibautil.exe in \APPS\BOOTAGNT) to disable the WoL fea-
ture on adapters that do not require WoL capabilities. On server adapters, the WoL feature is disabled
