LED Indicators
The LED indicators of the Gigabit Ethernet Switch provide a real-time indication of
system operating statuses. There are three LED-indicators for each Gigabit
Ethernet port and one Power LED for the Unit.
POWER
The Power LED indicator is solid green when the Gigabit Ethernet Switch is
receiving power.
Link/Act
The Link/Act LED indicators are solid when there is a secure connection (or link)
to the desired port. A blinking LED indicator signifies reception or transmission (i.e.
Activity—Act) of data occurring on a port.
1000Mbps
The 1000Mbps LED indicators are solid when there is a secure connection (or link)
to a 1000Mbps Gigabit Ethernet device at the desired port.
100Mbps
The 100Mbps LED indicators are solid when there is a secure connection (or link)
to a 100Mbps Fast Ethernet device at the desired port.
Note: When the connection (or link) is 10Mbps, both the 1000Mbps and
100Mbps LED indicators are off.
