Receive (RVC) LED
This yellow indicator normally flashes to indicate that the MR9 is
repeating data packets received from that segment. The flash of the
LED is pulse stretched for viewing effect.

Link (LNK) LED
When this green LED is lit, it indicates that a twisted pair link has
been established between the applicable repeater port and the device
at the other end of the segment. Port 9 on the MR9T-C does not have
a LNK LED since Port 9 is a coax connection. The LNK LED remains
lit as long as a link is maintained.
On the MR9T, the Port 9 LNK LED flashes to indicate that the
polarity detection and correction feature has detected a polarity
mismatch on the Port 9 twisted pair RX (Receive) pair. The repeater
will continue to function normally in this condition. Polarity
detection and correction is incorporated into Ports 1 though 8 in
addition to Port 9 but the Port 9 LNK LED is the only one that can
indicate a polarity mismatch.
