Right View (GT-805A)
There are one RJ45 twisted-pair jack (auto-MDI/MDI-X), one
100/1000XSFPber-optic slot andfourLEDindicators. Also one
DIP switch for Link-Fault Passthrough (LFP) feature and “ON” to
turn on the LLCF and LLR detection. And “OFF” to turn off the
feature. Please refer to the following sections for more.

Power Information
The power jack of Gigabit Ethernet Media Converter is with
2.5mm in the central post and required +5VDC power input.
It will conform to the bundled AC-DC adapter and Planet’s
Media Chassis. Should you have the issue to make the power
connection, please contact your local sales representative.
Please keep the AC-DC adapter as spare parts when your
Gigabit Ethernet Media Converter is installed to a Media Chassis.

DC receptacle is 2.5mm wide that conforms to the Gigabit
Ethernet Media Converter’s 2.5mm DC jack’s central post. Do
not install any improper unit.

4.Link Fault Pass-Through (LFP)
The LFP function includes the Link-Fault-Passthrough function
(LLCF/LLR) and the DIP Switch design. LLCF/LLR can
immediately alarm administrators the issue of the link media
and provide efcient solution to monitor the network. The DIP
Switch will disable or enable the LFP function.
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 link of transmit. 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 link of transmit.
Note
LFP function is ON by default setting. If you are
familiar with the network installation and for diag-
nostic purpose (i.e. check which end is broken),
you can turn it off and reset the converter to
make it take effect. Otherwise, please remain it in
the default position.

5.Installing The Converter
To install GT-805A stand-alone, on a desktop or shelf, simply
complete the following steps:
Step 1: Turn off the power of the device/station in a network
to which the GT-805A will be attached.
Step 2: Attach ber cable from the GT-805A to the ber
network. TX and RX must be paired at both ends.
Step 3: Attach a Cat. 5/5e/6 UTP cable from the
10/100/1000BASE-T network to the RJ45 port on the
GT-805A.
Step 4: Connect the 5V DC power adapter to the GT-805A
and verify that the Power LED lights up.
Step 5: Turn on the power of the device/station; the TX Link
and FX Link LEDs should light up when all cables are
attached.

Note
1. It is recommended to use PLANET MFB/MGB
series 100/1000BASE-FX/SX/LX SFP on the
GT-805A. If you insert an SFP transceiver that
is not supported, the GT-805A will not recog-
nize it.
2. Please check the link-budget of your SFP trans-
ceivers and its physical wiring distance. In
some installation, an in-line optical attenuator
may be required to protect your transceivers.

6 Duplex Mode Support
The GT-805A TP port supports triple speed --
10/100/1000BASE-T, auto-negotiation. It will auto detect the link
speed and the duplex mode by default with its link partner. The
ber port (100/1000BASE-FX/SX/LX) allows 100/1000Mbps
full duplex by auto-negotiation. Please also check the setting
of the link partner as well.
