Figure 2. Front Panel of FN-800
There are 5/8 (five/eight) RJ-45 ports and one “Uplink”port
on the front panel. Each port is labeled with a port number.
One special port labeled with “Uplink”is converted from

port#1. You can either use Port#1 or “Uplink”port. The
“Uplink”port is used for connecting another hub through an
ordinary straight-wired twisted-pair cable by running one end
of straight cable to “Uplink”port and the other end to another
hub’s station port.
On the front panel, there are several LED indicators for
monitoring the device itself, and the network status. At a
quick glance of the front panel, the user would be able to tell
if the product is receiving power; if it is monitoring another
hub or concentrator; or if a problem exists on the network.
LED Indications
The following describes the function of each LED indicator.
LEDs Status Descriptions
PWR
(Power LED) Steady Green This LED light is located at the left side on the front panel. It will light
up(ON) to show that the product is
receiving power. Conversely, no light
(OFF) means the product is not
receiving power.
COL
(Collision
LED)
Blink
Red A “collision”in Ethernet, is when two end nodes transmit at the same
time. The indicator lights up
whenever there is a collision between
a directly attached end node and any
other node

FN-500/FN-800 User’s Manual 9
LEDs Status Descriptions
LNK
(Link LEDs) Steady Green Each RJ45 station port on the hub is assigned an LED light for monitoring
port "Good Link and Activity". Each
LED is normally OFF after the power
on operation, but will light up
steadily to show “Good Link”.
TX/RX
(Activities
LEDs)
Blink
Green Each LED is normally OFF after the power on operation and flash to show
that transmit and receive signals are
passing in and out the hub. The
flashing rapidly increases with the
network traffic.
Rear Panel
On the rear panel there are power DC jack, ID switch and two
expansion connectors. The following describes the function of
each connector and switch.

DC Power Jack
The power cord should be plug into this socket. The DC jack
accept DC power equal to 5 Volt , 2 Amp, minimum for FN-
500 and 4 Amp. minimum for FN-800.
ID Switch
This switch is for setting the address of each hub when stack
two or more hubs together. Each hub should have one unique
number. The switch has four positions (No.1 to 4), therefore,
there are 16 possible combinations, except the setting of all
positions at OFF is not allowed;i.e. 15 combinations only is
accepted. For example, the settings from position No.1 to 4
are “off off on on”, the corresponding ID number is “3”.
Expansion Connectors
For FN-500/FN-800, there are two DB25 female connectors at
rear panel . These two connectors have the same function then
user can stack another hub by choosing any one of them.
Therefore, if one is used for “stack up”, then the other is for
“stack down”. Any combination of 5/8 port hub is allowed
only within the limitation of 5 hubs in one stack.
