Introduction
The ONU-6100B-2x is an optical network unit (ONU) that
allows you to enjoy high-speed Internet access over optical
networks. The ONU-6100B-2x comes with one fiber, and one
10/100/1000 Mbps RJ-45 (LAN) port. No configuration is
required. On the ONU-6100B-2x, all device configuration is
done remotely by the OLT (Optical Line Terminal). Once you
have connected the hardware, you are ready to enjoy Internet
access.
Two ONU-6100B-2x models are discussed in this guide:
ONU-6100B-21 (with a 10km transceiver) and ONU-6100B-22
(with a 20km transceiver).

3.1 Desktop Instructions
Place the ONU-6100B-2x on a flat, level surface that is strong
enough to support the weight of the ONU-6100B-2x with
connection cables. Make sure there is a power outlet nearby.
3.2 Wall-mounting Instructions
Complete the following steps to hang your ONU-6100B-2x on
a wall.
1Select a position free of obstructions on a sturdy wall.
2Drill two holes large enough for the M4 tap screws. Make
sure the distance between the centers of the holes is
108mm.
"Be careful to avoid damaging pipes or cables
located inside the wall when drilling holes for the
screws.

3Do not insert the screws all the way into the wall. Leave a
small gap of about 0.5 cm between the heads of the
screws and the wall.
4Make sure the screws are snugly fastened to the wall.
They need to hold the weight of the ONU-6100B-2x with
the connection cables.
5Align the holes on the back of the ONU-6100B-2x with the
screws on the wall. Hang the ONU-6100B-2x on the
screws.
The following are dimensions of an M4 tap screw and
masonry plug used for wall mounting. All measurements are
in millimeters (mm).

Troubleshooting
1The POWER light is not on when I connect power to the
ONU-6100B-2x.
• Check that the power source is turned on.
• You might be using the wrong power adaptor. Use the
included power adaptor only.
• If you are using the correct power adaptor, disconnect
and re-connect the power adaptor to turn on the ONU-
6100B-2x again.
•IfthePOWER light is still not on, use a different power
outlet.
• If the problem continues, contact your local vendor.
2The PON light is off.
• Check the connector on the optical cable and the PON
port. Make sure they are clean and dust-free. Use an
air duster to clean the connectors. Do NOT use a wet
cloth to clean the connectors.
