Resetting the ONU

All settings will return to Factory Defaults; registration provisioning will be lost.

A reset button is available if the C424G ONU needs to be rebooted. The Reset button is located just above the USB port on the rear of

the C424G ONU. To reset the C424G ONU, press the RESET button for 10 seconds or longer.

Voice Processing

POTS uses in-band signaling tones and currents to determine call status (for example, call request). Because POTS allows for the

transfer of audio signals below 3.3 kHz, POTS systems are also used for modems that allow data transmission (referred to as dial up

connections).

Ethernet Interface

The C424G ONU supports data service through four 10/100/1000Base-T Ethernet interfaces via RJ-45 connectors.

Power

Power is provided by a 12 VDC Power Adapter that is included with the C424G ONU. The Power Adapter operates from a main power

source input of 100 to 240 VAC, 50/60 Hz, with a nominal output of 12 VDC. A connection for an optional un-interruptible power supply

(UPS) is also provided.

UPS

The C424G ONU provides an optional connection for an UPS. A UPS is a battery backup system designed to continue providing power

when the primary power source is lost. Power is supplied to the C424G ONU by a local power source with battery backup that utilizes the

AC power at the customer premises to keep the battery charged.

WiFi

The WiFi function allows you to connect wireless devices without entering a “pre-shared password key” in the device. WiFi supports the

following protocols:

■802.11 b/g/n support on 2.4GHz radio with 2x2 MIMO antenna design

■802.11 a/n/ac support on 5GHz radio with 4x4 MU-MIMO antenna design

gNOTE

The “pre-shared password key” is the default password and is located on the label of the C424G ONU.

WPS

The Wi-Fi Protected Setup (WPS) enables you to connect to wireless devices without entering a password in the device you are

connecting to. WiFi is enabled by simultaneously pressing the WPS button on the C424G ONU and the WPS button on the device you are

connecting to for approximately 5-seconds.

USB

There is a USB data connection on the rear of the C424G ONU that can be used for connection and communications with other

computers and electronic devices. The USB port is USB 2.0 compliant with 500mA service for peripheral devices.

INSTALLATION

After unpacking the C424G ONU, inspect it for damage. If damage is noted, file a claim with the carrier and then contact ADTRAN. For

more information, refer to the warranty.

Installation consists of positioning the C424G ONU on a desktop, or on a wall and connecting POTS (PHONE), Ethernet, Fiber, and

power.

Installation Guidelines

The C424G ONU can be mounted on the base (included) or on a wall.

The following are guidelines for this installation.

■Read all warnings and cautions before installing or servicing the C424G ONU.

■Do not locate the C424G ONU in direct sunlight or next to any thermal obstructions.

61287781F1C-13A 3

Installation Overview

To install the C424G ONU, you will need to complete the following steps:

■“Step 1: Mounting Option”

■“Step 2: Connect VoIP (POTS)”

■“Step 3: Connect Ethernet”

■“Step 4: Connect Power”

■“Step 5: Connect Uninterrupted Power Source (UPS)”

Required tools

Standard technician tools and those listed below are required for installing the C424G ONU:

■Phillips-head screwdriver

■Two, RJ-11 connectors

■Four, RJ-45 connectors

■Wire strippers

■RJ-11 and RJ-45 crimpers

■PON power meter with wavelength filtering

■Fiberscope or videoscope

For fiber optic connections, the following is required:

■ODC Fiber cleaning tool

Step 1: Mounting Option

Installation consists of positioning the C424G ONU on either a desktop, or mounting it on a wall.

Desk Top Installation

With a desk mount, ensure the C424G ONU is not located in direct sunlight and is not located next to any thermal obstructions.

To attach the C424G ONU to the base, complete the following steps:

1. Snap the base on to the bottom of the C424G ONU.

2. Thread the fiber cable through the opening in the base. If there is excess fiber, carefully wrap it around the Fiber Tray.

Remove the plug from the SC/APC Connector and insert the fiber cable. Retain this plug and insert it in the fiber connection when the

fiber cable is not connected. This will protect the optical portion of the connection.

Wall Mount Installation

To wall mount the C424G ONU, complete the following steps:

1. Decide on a location for the C424G ONU. Mount below eye-level so the LEDs are visible.

2. Attach a 1/4 inch mounting board (typically plywood) to the wall. If the wall is drywall construction, ensure the mounting board is

supported by the wall studs.

3. Install two #8 Pan Head screws (1 inch or greater in length) using the key holes on the bottom of the C424G ONU as location

markers. Leave approximately 1/4 inch protruding from the mounting surface.

4. Slide the C424G ONU 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.

Step 2: Connect VoIP (POTS)

Refer to Figure 1 and insert the RJ-11 connector in to one of the two VoIP ports.

4 61287781F1C-13A

Step 3: Connect Ethernet

The C424G ONU supports four, 1 Gigabit (10/100/1000Base-T) connections (1 to 4).

If Ethernet cables are not available, use the following procedure and table to create the Ethernet cables:

1. Trim the insulation for the subscriber Ethernet cable.

2. Using a CAT 6 cable, connect the wires per the following table using an RJ-45 Crimper.

3. Refer to Figure 1 and insert the CAT 6 rated cable in the appropriate Ethernet port.

Step 4: Connect Power

Refer to Figure 1 and plug the 12 VDC Power Adapter (supplied with the unit) into the 12V DC2.5A connection on the rear of the chassis.

Connect the AC plug to a standard 120 VAC outlet.

Step 5: Connect Uninterrupted Power Source (UPS)

The step is optional. The C424G ONU can typically use an un-interruptible power supply (UPS) if desired. Power is supplied to the

C424G ONU by a local power source with battery backup that utilizes the AC power at the customer premises. The UPS powers the

C424G ONU supplying continuous 12 VDC. Refer to the installation material that is provided with the UPS.

To connect UPS, refer to Figure 1 and connect a UPS cable from the source to the UPS port on the rear of the unit.

gNOTE

ADTRAN offers a UPS Cable assembly (P/N 1287402G1) for this connector.

The UPS Power/Alarm Connections Table below defines each pin on the connector.

UPS Power/Alarm Table

The following table below provides a pinout of the UPS connection.

If an UPS is being used and its internal battery is disconnected or fails, the C424G ONU is not protected from power outages, and will

send a “Battery Missing” alarm to the OLT.
