OfficeConnect LED Indicators
OfficeConnect Dual Speed Switch 8 Plus
Alert LED
(Orange) Alerts you to
excessive network use or
an isolated (partitioned)
10BASE-T and 100BASE-
TX port.
Power LED
(Green) Indicates that the
power supply to the unit
is present.
Port Status LEDs
(Green/Yellow) Indicate
the status of each port. If
green, there is a link
present at 100 Mbps. If
yellow, there is a link
present at 10 Mbps. If
the LED is off, nothing is
connected. Flashing of an
LED indicates activity over
that link.
Duplex Indicator
(Orange) If the LED is
orange, the link is
running at full duplex. If
the LED is off but there is
a link on that port, that
link is running at half
duplex.
As this front view of the OfficeConnect Dual Speed Switch 8 Plus illustrates, OfficeConnect
units offer a variety of LED indicators. For instance, the Alert LED available on ‘Plus’
switches. This gives users immediate notification of problems, such as excessive network use,
without requiring special technical knowledge.
