Chapter 1 OVERVIEW
Thank you for purchasing PLANET GT-80X family Gigabit
Ethernet Media Converter products. This Gigabit Ethernet
Media Converter is used to convert one type media signal to
other type equivalent that allows two type segments connect
easily, efciently and inexpensively. The Gigabit Ethernet
Media Converter introduced here provides one channel
media conversion between the 10/100/1000Base-T and
1000Base-SX/LX,1000Base-SX/LX through SFP Mini-GBIC
(GT-805A only) or the 1000Base-LX WDM (GT-806A15/B15
and GT-806A60/B60 only).
This Gigabit Ethernet Media Converter can be used as a
standalone unit or as a slide-in module to the 10”/19”
media chassis (up to 15 units) for a multi-mode and single-
mode Fiber combined networks at a central wiring closet.
Please contact with your sales representative for more about
the 10”/19” media chassis.
About the Gigabit Ethernet Media Converter
This Gigabit Ethernet Media Converter utilizes a netrwork
technology specied by IEEE 802.3 10Base-T, IEEE 802.3u
100Base-TX, IEEE 802.3ab 1000Base-T and IEEE 802.3z
1000Base-SX/LX standards. The Gigabit Ethernet Media
Converter is used to converter one type media signal
to other type equivalent that allows two type segments
connect easily, effciently and inexpensively.

In the following sections, the term “GT-80X” indicates the
product family above, the term “MM” and “SM” represent
Multi-Mode and Single Mode ber-optic mode.
Notice:
Please note GT-806A15/806B15 and GT-
806A60/806B60 is designed to work
together. It means you must connect GT-
806A15 to GT-806B15 or GT-806A60 to
GT-806B60 from them to work normally.
If both ends are GT-806A15 or GT-806A60
and GT806B15 or GT-806B60, they can’t
work normally and may damage the fiber
connectors.

Chapter 6 INSTALLING THE CONVERTER
6.1 Stand-alone Installation
To install a GT-80X 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-80X will be attached.
Step 2: Ensure that there is no activity in the network.
Step 3: Attach ber cable from the GT-80X to the ber
network. TX, RX must be paired at both ends.
Step 4: Connect the 5VDC power adapter to the GT-80X
and verify that the Power LED lights up.
Step 5: Turn on the power of the device/station; the PWR
LEDs should light when all cables are attached.

Figure 6-1 GT-80X installation
Notice:
Please refer to Section 9 for detailed wiring
information of the GT-80X.
To prevent from optic acceptor malfunction,
check the both wires / transmitter before
power on the converter.

15
GT-805A Installation
Step 1: Connect the ber cable. Attach the duplex LC
connector on the network cable into the SFP
transceiver.
Step 2: Attach ber cable from the GT-805A to the ber
network. TX, RX must be paired at both ends.
Step 3: Connect the 5VDC power adapter to the GT-805A
and verify that the Power LED lights up.
Step 7: Turn on the power of the device/station; the PWR
LEDs should light when all cables are attached.
Figure 6-2 GT-805A installation
Notice:
It recommends using PLANET MGB-SX /
MGB-LX series 1000Base-SX/LX SFP on the
converter. If you insert a SFP transceiver
that is not supported, the converter will
not recognize it.

6.2 Chassis Installation and Rack Mounting
To install the media converter in a 10-inch or 19-inch with
standard rack, follow the instructions described below.
Step 1: Place your GT-80X on a hard at surface, with the
front panel positioned towards your front side.
Step 2: Carefully slide in the module until it is fully and
rmly tted into the slot of the chassis.
Figure 6-3: Insert a media converter into an available slot
Step 3: Attach a rack-mount bracket to each side of the
Chassis with supplied screws attached to the
package.
Step 4: After the brackets are attached to the chassis, use
suitable screws to securely attach the brackets to
the rack, as shown in Figure 6-3.
Step 5: Proceed with the steps 4 and steps 5 of session
6.1 Stand-alone Installation to connect the
network cabling and supply power to your switch.

Caution:
You must use the screws supplied with
the mounting brackets. Damage caused to
the parts by using incorrect screws would
invalidate your warranty.
