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 moni-
toring of hub and network activity. The
Alert LED ensures immediate notification
of problems such as excessive network
use without requiring special technical
knowledge on the part of users.
Alert LED
(orange)
Alerts you to
excessive network
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 8/TPO 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 (OfficeConnect Hub 8/TPC only)
can only be yellow or off. It will be yellow
if the port has partitioned.
Network
Utilization LEDs
(OfficeConnect
Hub 8/TPC,
8/TPM, TP800,
and TP1200 only)
(green/yellow/
orange)
Indicate how much
your network is
being used.

ing: Disconnect Unknown Device
(DUD), which allows the hub to dis-
able a port with an unknown device
attached to it or report the incident to
a management station; Need To
Know (NTK), which prevents unau-
thorized devices from intercepting
confidential communications
■ Configurable Alert LED lights when a
selected condition such as a preset
level of collisions, coaxial port parti-
tion, log-in violation, or port security
violation occurs
■ Serial port for connecting a manage-
ment terminal
■ Remote Support Tool allows the hub
to be configured to monitor the net-
work and report conditions to a
reseller or centralized management
