HP 100Base-T Hub 8 Installation and Reference Guide

Hardware Reference 4-3

For example, if network utilization reaches 1%, the LED labeled 1% will

light up. However, if network utilization rises above 1% (e.g., 12%), the

LED labeled 12 and all the other LEDs before it (i.e., 1 and 6) will also

light up in rapid succession. These indicators monitor the share of valid

network frames handled by the hub within a 100 Mbit/s bandwidth. They

provide a quick way to monitor the current traffic load relative to the

network’s capacity.

Col

Color: Yellow

Function: Intrahub packet collision

The relative rate of collision is indicated by the degree of brightness and

blinking of the Col indicator.

Note: If the hub displays a high collision rate, check to see if any of the connected

devices are malfunctioning or if a loop has been formed in your network

connections. Otherwise, you may need to reconfigure your network to balance

the traffic load.
