Configuration 7
Port Partitioning
Any messages or data packets received from any port by the repeater
are transmitted to all ports. The corresponding LED displays the port
status and the port partition activity. The LED is on when the port is
either active or not partitioned, and it is off when nothing is connected to
the port or the port is autopartitioned. When the port is partitioned by
management, the LED flashes approximately twice a second, independent
of any other partitioning.
The DECrepeater 90T status LEDs show the status of the repeater. The
status may or may not be a fault of the repeater. Table 2–2 contains
both repeater fault and non-repeater fault conditions. Each port is
automatically controlled and can be partitioned for any of the reasons
in the following table:
