This indicator lights green when the switch is receiving power; otherwise,
it is off.
2.3.1.2 100M LED
The 100M LED indicates the link speed of each port. If the LED lights
green, the connection speed is 100Mbps, off for 10Mbps.
2.3.1.3 Link/Act LED
Every port has a Link/Activity LED. Steady green (link state) indicates
that the port has good linkage to its associated devices. Flashing green
indicates that the port is receiving or transmitting data between its
associated devices.
If the port is connected but the Link/Activity LED is dark, check the
following items:
1. The switch and the connected device’s powers are on or not
2. The cable is firmly seated in its connectors in the switch and in the
associated device.
3. The connecting cable is good and with correct type
4. The connecting device, including any network adapter is functioning.
From the 100M and Link/Activity LED, we could judge the connection
speed as following:
