MONITORING AND TROUBLESHOOTING
4-2
XMT (Transmit)
When flashing Green, XMT indicates that the BRIM-T6 is transmitting
traffic to the Token Ring network. When solid Red, XMT indicates that the
BRIM-T6 is disabled.
When blinking Red, XMT indicates a speed fault condition, typically
caused by a mismatch in ring speeds between the BRIM-T6 and the ring
occupied by the device to which it is linked. See Section 2.3 for
information about setting the correct ring speed.
RCV (Receive)
When solid Green, RCV indicates that the BRIM-T6 is currently enabled
to receive Token Ring traffic, and when flashing Yellow, it indicates that it
is currently receiving Token Ring traffic. When solid Red, RCV indicates
that the BRIM-T6 is disabled by the host device.
STB (Standby)
When solid Yellow, STB indicates a standby condition: the BRIM-T6 is
not ready or able to transmit data to the ring. Standby conditions are
caused, typically, when the host device is initializing or when a TPIM is
not attached to the BRIM-T6.
LNK (Media Link OK) on attached TPIM
When solid Green, LNK indicates that a connection exists between the
BRIM-T6 and a node at the other end of the media segment. When off, (or
also when Red on the TPIM-T1/-T2/-T4) this LED indicates either that the
BRIM-T6 is not connected to another device or that the port is not
receiving a signal.
