Port Indicators
The AT-3624TRS port indicators on the hubs’ front panels provide visual
diagnostic and activity information for network analysis. Each 10BASE-T
port supports the following indicator functions with one two-color front
panel LED per port:
LINK (Solid Green)—This indicates that the particular port has a valid
link and is not partitioned.
RECEIVING (Flashing Green)—When a port’s LED is blinking, the port
is receiving Ethernet packets.
PARTITIONED (Solid Amber)—A solid amber port indicator means the
port is partitioned or segmented from the rest of the ports. This may occur
by a management function or by an error condition on the link.
COLLISION (Flashing Amber)—A momentary amber flash occurs when
a collision is detected on the port.
NO LINK (No Light)—If the link test function is not met by the
10BASE-T device at the opposite end of the UTP segment, this LED will
not illuminate. This may occur if the workstation at the end of the
segment is turned OFF or if the UTP segment is disrupted or damaged.
SELF-TEST (Sequential Flashing Green)—This indicates the repeater is
conducting a power-ON self-test. The test continues until one port is
connected (valid link).
