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.
