The rear panel of the Gigabit Ethernet Media Converter indicates

one DC jack, which accepts input power with 5V DC 2A.

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

Note

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

function (LLCF/LLR) and the DIP Switch design. LLCF/LLR can

immediately alert administrators about problems with the link

media and provide an efﬁ cient 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 ﬁ ber will

disconnect the link of transmit. With LLR (Link Loss Return),

when a device connected to the converter and loses the ﬁ ber

line link, the converter's ﬁ ber will disconnect the link of transmit.

Both can immediately alert administrators about link media

problems and provide an efﬁ cient 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 conﬁ guration with a

good link status using the FCU-280x for remote connectivity.
