Fiber (FIBER)
GPON/Active Ethernet is supplied to the Micro ONT using an SC/
APC Fiber connection located on the rear of the unit.
Ethernet Interface (LAN)
The Micro ONT supports data service through one 10/100/
1000BASE-T Ethernet interface.
Power
The power feed is +12 VDC from the included AC to DC Adapter.
The adapter plugs into the PWR connector. The total power
consumption is approximately 5 watts.
ONT Reset (RESET)
Refer to Figure 1 for the location of the Reset button.
Reset the Micro ONT if you need to reboot the unit. The RESET
button is accessed through an opening on the bottom of the unit.
To reset the Micro ONT, insert a small pin (paper clip) into the
RESET opening and hold the button down for 10 seconds.
The Micro ONT will automatically download the latest provisioning
after the reset process has completed.
INSTALLATION
Before installing the Micro ONT, inspect it for damage. If damage
has occurred during shipping, file a claim with the carrier and then
contact ADTRAN. For more information, refer to the warranty.
Installation Guidelines
The following are guidelines for this installation.
■Read all warnings and cautions before installing or servicing
the Micro ONT.
■Do not locate the Micro ONT in direct sunlight or next to any
thermal obstructions.
■When the SC/APC fiber connection is not in use, replacing the
Protective Cover will help keep the optical connection clean.
■This product should not come in contact with water or other
liquids.

The Micro ONT supports a 1 Gbps (10/100/1000BASE-T)
connection (LAN).
Refer to Figure 1 and insert a Category 5e or better Ethernet
cable in the LAN Port.
Step 3: Connect Fiber
Do not view directly with optical instruments.
This product contains a Class 1 Laser module that complies with
21 CFR 1040.10 and 1040.11 and IEC 60825-1.
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
Fiber is installed in an SC/APC connector (FIBER) located on the
rear of the Micro ONT (see Figure 1).
Complete the following steps to install fiber.
1. Refer to Figure 2 and remove the protective cover from the
SC/APC Connector.
Figure 2. SC/APC Protective Cover
2. Clean the ends of the incoming fiber patch cord.
3. Before installing the fiber, use an optical power meter to
measure the power level. The power level should not
exceed –8.0 dBm. Use an appropriate bi-directional optical
attenuator if the power levels are at or above –8.0 dBm. A
level between –8.0 dBm and –27.0 dBm is acceptable, but
levels between –12.0 dBm and –18.0 dBm are optimal.
4. Refer to Figure 3 and connect the incoming fiber patch cord.

Installation Steps
To install the Micro ONT, complete the following steps.
Step 1: Position the Micro ONT
The Micro ONT can be mounted on a wall, or on a desk top.
Wall Mount Installation
To wall mount the Micro ONT complete the following steps:
gNOTE
Refer to Figure 1 when installing the Micro ONT on a wall.
1. Determine a location for the Micro ONT.
2. Use the key holes (2 inches apart) on the back of the Micro
ONT as a template and install two #6 drywall anchors.
3. Install two #6 pan head screws. Leave approximately 1/4
inch protruding from the mounting surface.
4. Slide the Micro ONT over the pan head screws and exert a
small amount of downward pressure to ensure that the top of
the slots are resting on the shafts of the pan head screws.
Desk Top Installation
The Micro ONT can be located on a desk top. Ensure the Micro
ONT is not located in direct sunlight, next to any thermal obstruc-
tions, sources of moisture, or liquids.
Step 2: Connect Ethernet
fCAUTION!
The product is intended for indoor use only. Ethernet cable and
attached equipment are intended for use within the same building
with equipotential bonding, and not intended to be placed in
separate buildings or structures. Failure to deploy as described
could result in permanent damage from lightning or other
electrical events and voids the warranty.

Step 4: Connect 12 VDC Power
Refer to Figure 1 and the following steps when connecting power.
The Micro ONT is powered by a 12 VDC connection.
12 VDC Connection
To power the Micro ONT, complete the following steps:
1. Plug the supplied 12 V AC/DC power converter into the PWR
connection.
2. Connect the power plug to a standard AC outlet. This
immediately turns the unit ON.

TROUBLESHOOTING
The following table provides troubleshooting tips.
Problem Possible Solution
The FIBER LED contin-
ues flashing Green
■Use an optical power meter to check
the receiving power to see if it between
–27 dbm and –8 dbm.
■Reset the ONT using the Reset button.
If the ONT fails again, replace the ONT
with another unit.
The Power LED is Off ■Make sure the power cable connector
is properly seated in the ONT power
input.
■Verify that the power adapter is
plugged into a live AC outlet.
■Check the power cable for shorts or
breaks.
■Disconnect the power input connector
at the ONT; use a voltmeter to verify
that the proper voltage level is present
on the 12 V pin (power and power
return) from the power adapter.
The LAN LED is green ■During boot-up, the LED will flash
green. This is normal. Once boot-up is
complete, the LED will illuminate solid
green. When data is transmitted, the
LED will flash green. If the LED
remains solid green, contact the
Central Office to verify that the ONT
serial number, password, and vendor
ID match those provisioned in the
database.
■If provisioning is correct, have the
Central Office determine if there are
alarms on the PON feeding the ONT. If
no alarms exist, use an optical power
meter to troubleshoot the fiber
network.
