2. Checklist

Your GT-805A carton should contain the following items:

The Gigabit Ethernet Media Converter

AC-DC Power Adapter (Output: 5V DC, 2A max.)

This User’s Manual

If any item is missing or damaged, please consult the dealer from
whom you purchased your Gigabit Ethernet Media Converter.

The GT-805A comes with one vacant SFP module
slot. The mini GBIC SFP module is not bundled in the

Note

package.

Front View

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 o the

feature. Please refer to the following sections for more.

Power Information

The power jack of Gigabit Ethernet Media Converter measures

2.5mm in the central post and requires +5VDC power input.
It conforms 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.

The AC-DC adapter is used as a spare part when your Gigabit
Ethernet Media Converter is installed to a Media Chassis.

2.5mm
DC Receptacle 2.5mm
+5V for each slot

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)

LFP function is ON by default setting. If you are
familiar with the network installation and for
diagnostic purpose (i.e. check which end is broken),

Note

you can turn it off and reset the converter to make
it take effect. Otherwise, please keep it in the default
position.

5. 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.

6. LED Indication

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

e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 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.
