Front-Panel Components

The front panel of the Switch consists of LED indicators, 5 (10/100/1000 Mbps) Ethernet ports.
Comprehensive LED indicators display the status of the Switch and the network.

LED Indicators

The LED indicators of the Switch include Power, 100/1000Mbps, and Link/Act. The following shows the LED
indicators for the Switch along with an explanation of each indicator.
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 − 1000Mbps/Green; 100Mbps/Amber; 10Mbps/Off
This indicator is amber-colored when the port is connected to a 100Mbps Fast Ethernet station. It is
green when the port is connected to a 1000Mbps Ethernet station. It is not illuminated when the
port is connected to a 10Mbps Ethernet station.
Cable Diagnostic − LED Indications
When the Switch is booted up (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-circuited), and improper termination (a termination resistance greater than
