Fiber Data port indicator is off
If the Fiber Data port indicator is off, it means that the Ethernet link is down. Check the
following:
• The fiber adaptor is correctly inserted at the CMU.
• The fiber cable is correctly connected to the adaptor.
• The associated network equipment (router, switch etc.) is powered up and operating
correctly.
• The fiber port in the associated equipment is enabled.
• The fiber cable between the CMU and the network equipment is connected and is not
damaged. If possible, substitute a known good fiber cable.
If these steps fail to resolve the problem, continue at Entering recovery mode on page 7-
71, selecting the option to reset IP and Ethernet configuration.
