Introduction
The ONU-6040B-2x is an optical network unit (ONU) that
allows you to enjoy high-speed Internet access over optical
networks. The ONU-6040B-2x comes with one fiber and four
10/100 Mbps RJ-45 ports. No configuration is required. On
the ONU-6040B-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-6040B-2x models are discussed in this guide:
ONU-6040B-21 (with a 10km transceiver) and ONU-6040B-22
(with a 20km transceiver).

3 Hardware Installation
The ONU-6040B-2x can be placed on a desktop or mounted
on a wall.
3.1 Desktop Instructions
Place the ONU-6040B-2x on a flat, level surface that is strong
enough to support the weight of the ONU-6040B-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-6040B-2x on
a 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-6040B-2x with
the connection cables.
5Align the holes on the back of the ONU-6040B-2x with the
screws on the wall. Hang the ONU-6040B-2x on the
screws.
