4.4 DAG 4.3GE Card Capture Session
Description
A successful DAG 4.3GE card capture session is accomplished by
checking receiver ports optical signal levels and checking the card has
correctly detected the link. This is followed by configuring DAG for
normal use.
Procedure
Follow these steps to troubleshoot DAG 4.3GE card configuration.
Step 1.
Check Receiver Ports Optical Signal Levels.
The card supports 850 nanometer multimode fibre attachments with optical
signal strength between 0 dBm and -22 dBm.
If in doubt, check card receiver ports light levels are correct using an optical
power meter.
The card receiver ports are the lower of each dual-LC-style connectors, the
closest to the PCI-X slot.
Cover unused ports with LC-style plugs to prevent dust and mechanical
hazards from damaging optics.
Step 2.
Check FPGA Image Loaded.
Before configuring the card, ensure the most recent FPGA image is loaded
on the card.
