Fiber Optic Ports
The following checklist provides recommended actions to take to resolve
problems installing the AT-2914 adapter card or running it in your system.
Note
Before opening the cabinet of your system for removing or inserting
the adapter card, review all precautions outlined under "Reviewing
Safety Precautions" on page 31.
Inspect all cables and connections. Verify that the cable connections
between the adapter and the switch are attached properly.
Verify that you match the wavelength of the network adapter port with
the wavelength of the switch port. The AT-2914SX/SC or
AT-2914SX/LC network adapter should be connected to a
1000BASE-SX switch port. For the AT-2914SP and AT-2914GP/SP
network adapters, the wavelength of the SFP installed to the network
adapter must be matched with the wavelength of the switch port.
Verify that the TX port of the fiber connector is connected to the RX
port of the link partner and RX port of the fiber connector is connected
to the TX port of the link partner.
If you are using Bi-Di optical transceiver, verify the wavelengths are
reversed. The TX port of the fiber connector on the 2914 series
network adapter has the same wavelength as the RX port of the link
partner and the RX port on the 2914 series network adapter has the
same wavelength as the TX port of the link partner.
Check the adapter installation by reviewing Chapter 2, "Installing the
Hardware" on page 29.
Make sure that the adapter card is properly seated in a PCIe slot.
Check for specific hardware problems, such as obvious damage to
board components or the PCIe edge connector.
Check the configuration settings and change them if they are in conflict
with another device.
Make sure that your system is using the latest BIOS.
Try inserting the adapter card in another slot. If the new position works,
the original slot in your system may be defective.
Replace the failed adapter card with one that is known to work
properly. If the second adapter card works in the slot where the first
one failed, the original adapter card is probably defective.
Install the adapter card in another functioning system and run the tests
again. If the adapter card passed the tests in the new system, the
original system may be defective.
