CHAPTER 3: USING LANVIEW
TWR (Twisted Ring)
When ON, this Red LED indicates an undesirable cable connection. TWR illuminates when you connect A to A, or B to B, instead of A to B, or B to A. The BRIM-F6 supports undesirable configurations, but alerts you to them. (Appendix A summarizes FDDI connection rules.)
WRP (Wrap)
This Red LED is ON when the BRIM-F6 detects an FDDI ring wrap. This means there is a break in the ring, and the system has combined the primary and secondary rings into one ring.
XMT (Transmit)
When ON, this Green LED indicates that the BRIM-F6 is transmitting traffic to the FDDI network. On a network with average traffic, the XMT LED normally flashes.
RCV (Receive)
When ON, this Amber LED indicates that the BRIM-F6 is receiving FDDI traffic. On a network with average traffic, the RCV LED normally flashes.
LNK (Media Link OK)
When ON, this Green LED indicates that a connection exists between the BRIM-F6 and the node at the other end of the port cable segment. To ensure you maintain the link, the port generates an idle signal when not transmitting data.
When OFF, this LED indicates that either nothing is connected to the BRIM-F6, or the port is not receiving any signal.
