LTR-T Installation Guide 13
Normal Operation
During normal operation the LTR-T displays the status and activity of all its attached
ports. The each port’s status is displayed as follows:
STAT LED Explanation
GREEN UTP ports
AUI ports
The link is good and receive polarity is correct.
or
the link test function and/or polarity correction is disabled.
The attached transceiver is functioning normally
or
the AUI port does not have a transceiver attached.
YELLOW UTP ports The LTR-T has detected reversed receive wires on this port and
is correcting the polarity before retransmitting the data. (Note:
if polarity correction is disabled, the LTR-T will neither check
nor correct the polarity of the data before retransmitting.)
RED UTP ports
AUI ports
The port is failing the link test if the test is enabled
and/or
the port has been automatically partitioned from the network
due to excessive collisions.
(Note: ports which have link test enabled, but are not connected
to a device at the opposite end of the segment will fail the link
test.)
The port has been automatically partitioned from the network
due to excessive collisions. In this state the port continues to
transmit, but receive data and collisions are ignored until the
LTR-T is able to determine that the segment is no longer bad.
(Note: if the AUI port is connected to a Thickwire/Thinwire
segment that is not terminated properly, the port will be
partitioned by the LTR-T.)
Blinking UTP and
AUI ports The port was auto-partitioned out (due to line errors) and
subsequently reinstated and is operating normally. The blinking
can be stopped by pressing the left MODE button.
Off UTP and
AUI ports The port has been manually partitioned from the network by the
user and is not capable of transmitting or receiving data (see the
section on Configuration for more information.)
