Fiber Uplink Port
The LED indicator for the fiber uplink port is located on the RJ-45 connector of the
downlink port next to the power connector. There are four LED functions for the
fiber uplink port.
The fiber uplink port LED functions are as follows:
• Glows green when a link is established on the fiber port.
• Glows green indicating a valid link, then blinks green when activity is detected
on the fiber port.
• When the LED is OFF, there is no link (check cabling, check remote device).
• Blinking LED - indicates the device attached to the other end of the fiber maybe
passing Link Fault Propagation, or generating noise onto the fiber. This normally
happens when there is a media converter at the fiber end of the link. Connect
the second port of the converter onto a valid device to generate link.
Twisted Pair Uplink Port
When the Access Converter/3 is configured with a twisted pair uplink port, the LED
location and functionality is the same as that for the downlink ports.
