Indicators
10Base-T port LEDs
There are two built-in LEDs, located on the 10Base-T connector, which provide Link and Port Activity information.
The Link LED (green) is active when the port is connected to another powered 10BaseT port whose signaling
meets the requirements for an IEEE 802.3i 10BaseT device. For example, valid Link test pulses are detected on
the receive pair.
The Activity LED (green) is active when receive activity is detected or during a packet transmission.
Power LED
The Power LED (green) is active when power is provided to the unit.
Fault LED
The Fault LED (amber) is active when a fault is detected during power up diagnostics.
