Hub State Indicators
♦ Power Indicator
This indicator lights green when the hub is receiving power; otherwise, it
is off.
♦ Collision Indicators (COL10 and COL100)
These indicators indicate data collisions on the respective 10Mbps Ether-
net or 100Mbps Fast Ethernet segments of the hub. (If several hubs are
stacked or linked together, all of them should detect and indicate the same
collision, since collisions span the entire network segment.) Whenever a
collision is detected, the respective COL indicator will briefly blink am-
ber.
