Indicates percentage utilization of LAN
bandwidth.
The Utilization LEDs indicate the percentage of network bandwidth used by
valid data. The hub updates this display every 0.5 seconds.
There are five LEDs that represent the percentage of network utilization. The
corresponding LEDs light to show that the percentage utilization of LAN
bandwidth has reached this level. When active, these LEDs look like a stereo's
equalizer display.
For example, if network utilization reaches 1%, the LED labeled 1% lights.
However, if network utilization rises above 1% (for example, 30%), the LED
labeled 30 and all the other LEDs before it (that is, 1, 5, and 15) light in rapid
succession.
These LEDs monitor the share of valid network frames transmitted by this hub
within a 10Mb/s bandwidth. They provide a quick way to monitor the current
traffic load relative to the network's capacity.
