♦ Power This indicator operates when the Switch is turned
on. If this indicator is not lit, check the AC power connector
to ensure proper insertion of the power cord and that the
power switch is turned ON.
♦ 100Mbps/10Mbps The LED indicator lights when a 100
Mbps device is connected to a respective port or the uplink
port. If a 10 Mbps device is connected to a respective port or
the uplink port, the LED indicator is OFF.
♦ Link/Act These LED indicators are lit when there is a

They remain dark if there is no link. The LED indicators
blink whenever there is reception or transmission (i.e.
Activity—Act) of data occurring at a port.
