16 LTR-T Installation Guide
Link test mode is the first mode entered, and is indicated by the solid green PWR
LED. In this mode the LTR-T can enable/disable the link test function on any
combination of the UTP ports. The STAT LED above the lit ACT LED indicates
whether or not the link test is enabled on the selected port. Pressing
B
repeatedly
moves the ACT LED to each of the ports allowing the function to be
enabled/disabled on each of the ports independently. To exit link test mode press
both MODE buttons simultaneously.
Polarity correction mode (indicated by the yellow PWR LED) is entered after link
test mode. In this mode the LTR-T can enable/disable polarity correction on any
of the UTP ports. In the case of polarity correction, a yellow STAT LED
indicates that the function is enabled on the selected port. To exit polarity
correction mode press both MODE buttons simultaneously.
Manual partition mode (indicated by the solid red PWR LED) is entered after
polarity correction mode. In this mode the LTR-T can enable/disable partitioning
of any of the ports (UTP and AUI). Note that this function can be performed on
both AUI and UTP ports. In the case of manual partition, the STAT LEDs
display RED for those ports which have been manually partitioned from the
network. To exit manual partition mode press both MODE buttons
simultaneously.
Reconnection algorithm mode (indicated by the blinking red PWR LED) is entered
after manual partition mode. In this mode the LTR-T can enable/disable the
alternate reconnection method for all the ports in several combinations. For this
mode the UTP ports are configured together in groups of eight ports each and the
AUI port(s) are configured independently. UTP ports 1 to 8 are configured as one
group and UTP ports 9 through 16 (LTR16T) are configured as a second group.
The method for enabling/disabling the alternate reconnection method is similar to
that used in the above section on link test mode.
To return to normal operation in status mode press both MODE buttons simultaneously
from reconnection mode. If you save the configuration you set up (see next section) you
will also be returned to status mode.
Note that the LTR-T performs the actual modifications to the configuration upon
returning to status mode. Therefore, the LTR-T continues to perform its repeater
functions unchanged while in configuration mode.
