LED Indicators
The Dual-speed FriendlyNet Hubs contain LEDs, which indicate the power,
port activity and status. The LED nomenclature, color, and function are
described below:
❑
Power (green): Illuminates when AC power is applied to the Hub.
❑
Switch (green): The FH208B and the FH216B have an internal
switch (or bridge) module which enables simultaneous 10Mbps and
100Mbps transmission.
❑
Collision (yellow): A collision occurs when two or more stations in
the Ethernet network attempt to transmit data at the same time. The
LEDs will indicate a collision while the stations re-transmit. There
are two Collision LEDs:
❑
10Mbps segment
❑
100Mbps segment
