Hub LEDs
The 140T hub LEDs are located above and below the port LEDs. These
LEDs indicate the condition of the power supply, collisions per segment,
and the amount of traffic per segment.

LED Status Meaning
Power On Hub is receiving power.
Off Hub is not receiving power.
Collisions 10Mbps Blinking Collisions detected on 10Mbps segment.
Collisions 100Mbps Blinking Collisions detected on 100Mbps segment.
Traffic% (1-50+) On Gives an approximation of the traffic in
the 10Mbps or 100Mbps segments.
Off No network traffic on segment.
Segment Traffic
The traffic bar graphs (located below the port LEDs) provide a quick
reference on the current traffic load relative to the total available 10Mbps or
100Mbps network bandwidth. The graphs display a measure of the
percentage of bandwidth used on the respective network segment. Typically,
a segment showing more than 30% utilization indicates an overloaded
network.
The traffic percentage is determined by counting all data packets, whether
the packets are valid or not.
