LED Indicators
Comprehensive LED indicators display the conditions of the Switch and
status of the network. A description of these LED indicators follows
(see LED Indicators). The LED indicators of the Switch include Power,
Link/Act, 1000Mbps, and 100Mbps.
The Cable Diagnostic functions of
the Switch are indicated by a combination of the Speed and the Link/Act
LEDs, as described below.
Power Indicator
This green indicator illuminates when the Switch is receiving
power.
Link / Act
This green indicator illuminates steadily when a
port is connected to a station successfully and has
a good link. The indicator will blink to indicate
that a port is transmitting or receiving data on the
network.
Speed —
100Mbps/amber; 1000Mbps/green; 10Mbps/off
This indicator is green when the port is connected to a
1000Mbps Ethernet station. It is unlit when the port is
connected to a 10Mbps Ethernet station or 100Mbps Fast
Ethernet station.
Cable Diagnostic

LED Indications
When the Switch is first powered on, the Cable
Diagnostic function is initialized and run. The
Cable Diagnostic function will detect three
common faults in an Ethernet cable connecting the
Switch to a remote network device: an open circuit
(a lack of continuity between the pins at each end
of the Ethernet cable or a disconnected cable), a
short circuit (two or more conductors short-
