Note
The device is a power-required device, it means,
it will not work till it is powered. If your networks
should be active all the time, please consider
using a UPS (Uninterrupted Power Supply) for your
device. It will prevent you from network data loss
or network downtime.
In some areas, installing a surge suppression
device may also help to protect your Gigabit
Ethernet Media Converter from being damaged by
unregulated surge or current to the converter or
the power adapter.
4. LINK FAULT PASS THROUGH (LFP)
The LFP function includes the Link Fault Pass Through
function (LLCF/LLR) and the DIP Switch design. LLCF/LLR can
immediately alert administrators about problems with the link
media and provide an efficient solution to monitor the net. The
DIP Switch can disable or enable the LFP function.
With LLCF (Link Loss Carry Forward), when a device connected
to the converter loses the TP line link, the converter’s fiber will
disconnect the link of transmit. With LLR (Link Loss Return),
when a device connected to the converter and loses the fiber
line link, the converter’s fiber will disconnect the link of transmit.
Both can immediately alert administrators about link media
problems and provide an efficient solution to monitor the net.
Link Loss Carry Forward (LLCF)
The FCU-280x incorporates an LLCF function for troubleshooting
a remote connection. When LFP function is enabled, the FL/TP
ports do not transmit a link signal until they receive a link signal
from the opposite port.
The diagram below shows a typical network configuration with a
good link status using the FCU-280x for remote connectivity.

If the connection breaks, the FCU-280x link loss forwards to the
switch/hub that generates a trap to the management station.
The administrator can then determine the source of the issue.

Link Loss Return (LLR)
The fiber ports of the FCU-280x have been designed with an
LLR function for troubleshooting a remote connection. LLR works
in conjunction with LLCF.
When LFP function is enabled *(by default), the port’s
transmitter shuts down when its receiver fails to detect a valid
receive link. LLR should only be enabled on one end of the link
and is typically enabled on either the unmanaged or remote
device.
The diagram below shows a typical network configuration with
a good link status using the FCU-280x for remote connectivity.
Note that LLR and LLCF are enabled as indicated in the diagram.

If one of the optical conductors is bad (as shown in the diagram
box below), the converter with LLR function will return a no-link
condition to its link partner. With LLCF function also enabled,
the no-link condition is carried forward to the switch/hub
where a trap is generated to the management station, and the
administrator can then determine the source of the loss.

Note
LFP function is turned on by default. This feature
can also be turned off via the side DIP-switch.
If you are familiar with the network installa-
tion, for diagnostic purpose (i.e. check which
end is broken), you can turn it off and reset the
converter to make it take effect. Otherwise, please
leave it at the default position.

5. INSTALLING THE CONVERTER
Stand-alone Installation
To install a FCU-280x stand-alone, on a desktop or shelf, simply
follow the steps below:
Step 1: Turn off the power of the device/station on the
network to which the FCU-280x will be attached.
Step 2: Ensure that there is no activity in the network.
Step 3: Attach fiber cable from the FCU-280x to the fiber
network. TX, RX must be paired at both ends.
Step 4: Connect the 5VDC power adapter to the FCU-280x
and verify that the Power LED is lit.
Step 5: Turn on the power of the device/station; the PWR
LEDs should light when all cables are attached.
Figure 8: FCU-280x installation
Note
To prevent from optic acceptor malfunction, check
both wires / transmitter before powering on the
converter.
SFP Model Installation
Step 1: Connect the fiber cable. Attach the duplex LC
connector on the network cable into the SFP
transceiver.
Step 2: Attach fiber cable from the media converter to the
fiber network. TX, RX must be paired at both ends.
Step 3: Connect the 5VDC power adapter to the media
converter and verify that the Power LED is lit.
Step 4: Turn on the power of the device/station; the PWR
LEDs should light when all cables are attached.
Figure 9: SFP Model installation
Note
It’s recommended that Aaxeon SFP Modules be
used in the Aaxeon converters. If you insert a SFP
transceiver that is not supported, the converter
will not recognize it.

6. DUPLEX MODE SUPPORT
The FCU-280x is one-channel media conversion
between 10/100/1000Base-T and 1000Base-SX/LX. The
10/100/1000Base-T port can work under Auto-negotiation mode.
However, the 1000Base-SX/LX fiber port only works under forced
1000Mbps full duplex mode.
7. LED INDICATION
