Section 2 - Product Overview

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 the speciﬁed 100 ohms). Any of these common cable faults will be detected by the Cable
Diagnostic function and the LEDs will display the results of the Cable Diagnostic function as follows:

Open, Short, or Improper Termination:

LED: Amber

Link/Act LED: Off
