connected to other full-duplex devices or ports.
Lifetime limited warranty and
Provides complete piece of mind.
telephone support
MDI/MDIX push button switch Enables direct connection to a server, end station, or another switch or hub, using
regular straight-through cables.
Network utilization meter
Indicates how much of the network bandwidth is in use. These LEDs are continually
(available on most
updated to show when the network needs more bandwidth.

OfficeConnect LED Indicators
As this front view of the
OfficeConnect Fast Ethernet Hub
8 illustrates, each OfficeConnect
unit offers a variety of LED
indicators, including an Alert
LED to allow quick monitoring
of hub and network activity.
The Alert LED gives users
immediate notification of
problems, such as excessive
network use, without requiring
special technical knowledge.
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.
