1. Overview
Thank you for purchasing PLANET GTP-805A 1000BASE-X Fiber-
optic to 10/100/1000Mbps Ethernet twisted-pair 802.3at PoE
Bridge Converter. This converter is used to convert one type of
media signal to other type that allows two segments to connect
easily, efciently and inexpensively. The converter provides
Power over Ethernet power injector function which is able to
drive one IEEE 802.3at/802.3af compliant powered device.
About the Power over Ethernet Injector
The GTP-805A is an IEEE 802.3at/802.3af Power over Ethernet
Injector that provides 54V DC over Ethernet cables. To insert
DC voltage into Cat.5/5e/6 cables, allow the cable between the
Injector (GTP-805A) and PoE PD (Powered Device) to transfer
data and power simultaneously. The maximum distance between
the Injector (GTP-805A) and PoE PD is 100 meters. The
GTP-805A combines the Ethernet digital data with power over
the twisted-pair cables as an IEEE 802.3at/802.3af Power over
Ethernet Injector. And using the Power over Ethernet splitter, it
can separate the digital data and the power into two outputs.
The benets of PLANET GTP-805A are cost saving, easy for
networking planning and higher reliability. What’s more, once
any IEEE 802.3at/802.3af devices are installed, the GTP-805A or
PD can make the connection while migrating and the Ethernet
digital packets, such as connecting the GTP-805A to an IEEE
802.3at/802.3af complied device, wireless AP or IP Camera.

There is one DIP switch for Link Fault Passthrough (LFP)
feature. It is turned on for LLCF and LLR detection but this
feature is not operable when turned off. Please refer to the
following sections for more. There is also one DC 52V ~ 56V
power socket for the PoE+ Media Converter.

4. Link Fault Passthrough (LFP)
The LFP function includes the Link Fault Passthrough function
(LLCF/LLR) and the DIP switch design. LLCF/LLR can
immediately alert administrators to the problem of the link
media and provide an efcient solution to monitoring the net.
The DIP switch’s LFP function can be disabled or enabled.
LLCF (Link Loss Carry Forward) means when a device is
connected to the converter and the TP line loses the link, the
converter’s ber will disconnect the transmission link. LLR
(Link Loss Return) means when a device is connected to the
converter and the ber line loses the link, the converter’s ber
will disconnect the transmission link. Both can immediately alert
administrators to the problem of the link media and provide an
efcient solution to monitoring the net.
Link Loss Carry Forward (LLCF)
The GTP-805A incorporates an LLCF function for troubleshooting
a remote connection. When LFP function is enabled, the FL and
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 conguration with
a good link status using the GTP-805A for remote connectivity.

If the connection breaks, the GTP-805A that loses the link
will forward to the Switch/Hub that generates a trap to the
management station. The administrator can then determine the
source of the problem.

Link Loss Return (LLR)
The ber ports of the GTP-805A have been designed with an
LLR function for troubleshooting a remote connection. LLR works
in conjunction with LLCF.
When LFP function is enabled, the port’s transmitter is shut
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 conguration with
a good link status using the GTP-805A for remote connectivity.
Note that LLR and LLCF are enabled as indicated in the diagram.

If one of the optical conductors is down (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 off by default. This feature
can also be turned on via the DIP-switch. If
you are familiar with the network installation
and for diagnostic purpose (i.e. check which
end is broken), you can turn it on and reset the
converter to make it effective. Otherwise, please
put it in the default position.

5. Installing the Converter
Please follow these steps to install the PoE+ Media converter:
lTurn off the power of the device/station in a network to which
the GTP-805A will be attached.
lEnsure that there is no activity in the network.
lAttach ber cable from the GTP-805A to the ber network.
lAttach a Cat.5/5e/6 UTP cable from the 10/100/1000BASE-T
network to the RJ45 port on the GTP-805A.
lConnect the 52V~56V DC power adapter to the GTP-805A
and verify that the Power LED lights up.
lTurn on the power of the device/station; the TX Link and FX
Link LEDs should light up when all cables are attached.

The installation of the GTP-805A and the IEEE 802.3at/802.3af
Injector/Splitter
Before your installation, it is recommended to check your
network environment. If there is any IEEE 802.3at/802.3af
devices that need to be powered on, the GTP-805A can provide
you a way to supply power for this Ethernet device conveniently
and easily.
The GTP-805A equips an AC-DC adapter with DC 54V input and
it injects the DC power into the pin of the twisted-pair cable
(Pins 1, 2, 3 and 6).
