ROUBLESHOOTING
Follow these steps to help detect a link problem:
1 Clean the optical connectors, as described in the previous section.
2 Make sure that the connectors are plugged in correctly on both ends of the link.
3 Verify that the RX FLT LEDs (GBE and LDI) on the SummitGbX chassis are green on
both ends of the link. An RX fault can be caused by incorrectly connected fibers (for
example, TX-to-TX,) dirty or damaged connectors, or damaged fiber.
