Warning
Class 1 Laser product. L1
Warning
For SFP model AT-SPBD20EPON-13:
Laser Radiation.
Do not view directly with optical instruments.
Class 1M Laser product.
Rayonnement Laser.
Ne pas observer directement à l’aide d’instruments d’optique.
Appareil à Laser de classe 1M.
Warning
To prevent electric shock, do not remove the cover. No user-serviceable parts inside. This unit
contains hazardous voltages and should only be opened by a trained and qualified technician. To avoid
the possibility of electric shock, disconnect electric power to the product before connecting or
disconnecting the LAN cables.
Warning
Do not work on equipment or cables during periods of lightning activity.
Warning
Class I equipment. This equipment must be grounded. The AC power plug must be connected to a
properly wired earth ground socket outlet. An improperly wired socket outlet could place hazardous
voltages on accessible metal parts.
Additional notes and precautions:
Only trained and qualified personnel are allowed to install or to replace this equipment.
The uninterrupted power supply (UPS) unit must be mounted indoors, within 30 cable
feet of the gateway.
The power cord for the UPS is 8 feet long. The UPS must be mounted within 8 feet of a
power outlet.
The iMG can be installed indoors or outdoors.
If using a pluggable external AC power supply (PSU) to provide power, both the iMG
and the AC PSU must be mounted indoors. Refer to “Using an indoor AC Power Supply
Unit (PSU) with the iMG” on page 26.

Chapter :
AT-iMG2400 Series Installation Guide 10
All installation methods shall be in accordance with national and local regulations and
practices. The wiring method should include the use of Listed wire/cable acceptable for
the application per the National Code, and should be one that an Authority Having
Jurisdiction (AHJ) can approve per the Code.
Per NEC section 800.90 all exposed cables, service wires, or drops when entering a
building must have primary over voltage protection if they are classified as exposed
plant.
All iMG products have surge protection built in to meet EN55024.
AT-iMG2400 series products meet NEBS GR1089 Section 4.12, 6KW Lightning
Protection on the AC interface, when used with the AT-iMG008 series UPS.
Allied Telesis does not warrant against lightening and/or power surges causing damage
to the iMG. Such damage will be the responsibility of the equipment owner.
Ground resistance from the building primary bonding point to earth should be less than
25 ohms.
If the distance between the iMG and the AC meter ground connection is greater than
12-16 feet (the length of the #6 solid copper wire, not the point to point distance), a
separate ground stake should be installed for the iMG ground connection. In this case, it
is imperative that the AT-iMG008/AT-iMG008NB UPS be used, as it will prevent any
ground loop currents from flowing between the iMG and the AC ground system.

Installing the Gateway
Outdoor Installation
Required Tools and Supplies
Have the following tools on hand before you install the enclosure or gateway:
5/32 in. hex-pin security screwdriver
You may also need the following supplies:
Silicone sealant
UV-rated wire ties
USB-B console cable
AT-iMG017 15’ cable for UPS - or customer built
Single-fiber cable with UPC/SC connectors. This acts as a jumper cable from the
enclosure to the electronics unit, and must be at least 1 meter long.
Note
A jumper cable is not required, but the fiber cable in the enclosure must have a UPC/SC connector and
be long enough to connect to the electronics unit.
Fiber cleaning materials
Step 1: Check Package Contents
The following items are included in the electronics package. If any item is missing or damaged, contact your
Allied Telesis representative for assistance.
Note
Store the packaging material in a safe location. You must use the original shipping material if you need
to return the unit to Allied Telesis.
AT-iMG2426F electronics
Accessory Kit that includes:
2 POTS terminal bridges (if applicable)
7-pin DC terminal block

Chapter 2: Installing the Gateway
AT-iMG2400 Series Installation Guide 16
Step 2: Examine Outdoor Enclosure Configuration
The installer should have the Enclosure (AT-EN-SFR-ONT) configured as shown in the following figure.
Caution
Installation instructions are included with the Enclosure. You should follow all of its rules and
recommendations, such as using at least 6AWG copper for the ground wire.
Figure 3: Enclosure (AT-EN-SFR-ONT) - Ready for the Electronics Unit
Step 3: Check Power and Grounding
Battery Backup
The electronics unit is designed to be deployed with an uninterrupted power supply (UPS). You can purchase
an approved UPS from Allied Telesis (model number AT-iMG008/AT-iMG008G and AT-iMG008NB/AT-
iMG008GNB). Install the UPS according to the manufacturer’s instructions included in the package. (If you
wish to use any other UPS product, consult your Allied Telesis representative.)

Chapter 2: Installing the Gateway
AT-iMG2400 Series Installation Guide 17
Note
The NB product is shipped without batteries, to help prevent installing a UPS with a discharged
battery. The battery can be ordered separately (model number AT-iMG019).
Caution
Run the iMG BOND wire to the AC service bonding point to avoid exposing the iMG to GND
currents. (For example, do not ground the iMG to a connecting wire between two ground rods.)
Do not connect any other GND sources (ground rods) between the iMG and the AC meter box.
Option 1: Ungrounded UPS (Recommended)
Note
This is the preferred option, using the approved AT-iMG008 or AT-iMG008NB UPS.
Figure 4: Ungrounded UPS Configuration (Recommended)

Chapter 2: Installing the Gateway
AT-iMG2400 Series Installation Guide 18
Option 2: Grounded UPS
A grounded UPS (AT-iMG008G/AT-iMG008GNB) can be installed with the unit. The ground contact of the
AC receptacle that the iMG008G is plugged into must be verified to have a connection through the building
AC wiring system to the BPG.
Caution
This is acceptable only if required by local codes.
Note
Wire from the UPS to the iMG must be kept short in this topology. Recommended max distance is 30
feet (9 m).
Figure 5: Grounded UPS Configuration
Step 4: Install the Electronics Unit into the Enclosure
Note Connection Placement
Figure 6 shows the connections for the power, grounding, and WAN interface.

Chapter 2: Installing the Gateway
AT-iMG2400 Series Installation Guide 19
Note
In the enclosure there are two cable entrances. The left entrance is for power, grounding, and the fiber
cables. The right is for all telephone and LAN cables. Refer to Figure 7.

Snap the Unit into the Enclosure
To install the gateway, perform the following procedure:
1. Open the enclosure door and locate the hinge points at the left side of the enclosure base.
2. Align the tabs of the gateway with the hinges and snap into place. Refer to Figure 8.
