As this front view of
the OfficeConnect Hub
8/TPC 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 net-
work use or
an isolated
(partitioned)
10BASE-T port
and 100BASE-TX
port.
Power LED
(green)
Indicates that
the power
supply to the
unit is present.
Packet LED
(OfficeConnect
Hub TP4, 8/TPO,
TP400 only)
(yellow)
Flashes each
time a packet
is received on
a port.
Collision LED
(yellow)
Flashes each
time a collision
is detected on
the network.
Collisions are
part of normal
network
operation.
Port Status LEDs (green/yellow)
Indicate the status of each port. If
green, the link between the port and
the next piece of network equipment
is functional. If nothing is connected,
the LED will be off. If yellow, the port
has partitioned due to a fault on that
segment. The coaxial port LED
(where applicable) can only be
yellow or off. It will be yellow if
the port has partitioned or when
the port is not terminated.
Network
Utilization LEDs
(green/yellow/
orange)
Indicate how much
your network is
being used.
