Important Safety Instructions
With reference to unpacking, installation, use, and maintenance of your electronic
device, the following basic guidelines are recommended:
•

•
•
Do not use or install this product near water, to avoid fire or shock hazard. For
example, near a bathtub, kitchen sink or laundry tub, or near a swimming pool.
Also, do not expose the equipment to rain or damp areas (e.g. a wet basement).
Do not connect the power supply cord on elevated surfaces. Allow it to lie freely.
There should be no obstructions in its path and no heavy items should be placed
on the cord. In addition, do not walk on, step on, or mistreat the cord.
Use only the power cord and adapter that are shipped with this device.
To safeguard the equipment against overheating, make sure that all openings in
the unit that offer exposure to air are not blocked.
Avoid using a telephone (other than a cordless type) during an electrical storm.
There may be a remote risk of electric shock from lightening. Also, do not use
the telephone to report a gas leak in the vicinity of the leak.
Never install telephone wiring during stormy weather conditions.
CAUTION:
To reduce the risk of fire, use No. 26 AWG or larger telecommunication line cord.
Always disconnect all telephone lines from the wall outlet before servicing or
disassembling this equipment.
Although the light intensity of the fiber optic laser is low, there may still be a
small risk of damage to your eyes, especially if you wear glasses or contact
lenses. To increase your safety, you can take the following precautions:
oBefore turning on the equipment and connecting to the GPON port, check
that the fiber optic cable is not visibly damaged.
oNever look straight into the cable or GPON port under any circumstances,
even if no light is visible, since laser light is invisible to the human eye!
WARNING
Disconnect the power line from the device before servicing.
Power supply specifications are clearly stated in Appendix B.

Chapter 1 Summary
Comtrend’s CT-402 GPON (Gigabit-capable Passive Optical Network) provides a
high-speed data access corridor for customers to easily connect any media device,
achieving a Triple-play platform at home. The CT-402 not only conforms to the
ITU-T G.984 standard, but also embeds one 10/100/1000M Ethernet LAN port.
The CT-402 is easily controlled by a remote system that is flexible enough to
interoperate with the OLT units of different venders. It also supports DBA（Dynamic
Bandwidth Allocation）algorithm and QoS.

Chapter 2 Installation
2.1 Rear Panel
This diagram shows the rear panel of the CT-402.
GPON
PORT
Reset button
The installation steps for each rear panel interface is provided below.
Power Jack/Button
Press the power button to the OFF position (OUT). Connect the power adapter to
the power jack. Attach the power adapter to a wall outlet or other AC source. Press
the power button to the ON position (IN).
Caution 1: If the device fails to power up, or it malfunctions, first verify that
the power cords are connected securely. Then power it on again.
If the problem persists, contact technical support.
Caution 2: Before servicing or disassembling this equipment, always disconnect
all power cords and telephone lines from their outlets.
Reset Button
Restore the default settings of the device by holding down the Reset button for more
than five seconds. This may be required if the CT-402 fails to respond normally or
if you are locked out of the unit due to configuration changes.
GIGABIT LAN
Use a 1000BASE-T compliant RJ-45 cable to connect to a Gigabit LAN. This port can
also be used to connect to slower 10/100BASE-T networks. The port is auto-sensing
MDI/X and either straight-through or crossover cable can be used.
GPON PORT
Connect a single mode optical fiber to the ITU-T G.984 standard SC/APC connector.
NOTE: Avoid looking into the port, as there is some safety risk due to laser light.

2.3 Default Settings
The default settings are as follows:
•
•
•
•
Local (LAN) access (username: root , password: 12345)
LAN IP address: 192.168.1.1
LAN subnet mask: 255.255.255.0
Connection type: Bridge mode
NOTE: At power on, the device initializes all settings to default values. It then
reads the configuration profile from flash memory and overwrites them.
2.4 IP Configuration
These instructions describe the IP configuration steps for the Ethernet connection of
any computer connected to the CT-402 local area network. Once this connection is
established you will be able to access product features or manage the device using
the web user interface.
NOTE: These instructions are written for a computer running Microsoft Windows
XP SP2. For different operating systems, the specific steps may vary but
the general procedure is the same. Check the instructions provided with
your OS for further guidance.

STATIC IP Mode
To access CT-402 features your computer must have an IP address within the same
subnet. Follow the steps below to configure your computer correctly.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: On the dialog box that appears, select the radio button labeled “Use the
following IP address”. Enter an IP address in this format {192.168.1.x,
where x is any number greater than 2 and less than 254}. Enter a subnet
mask of 255.255.255.0. The settings should be displayed as shown here.
STEP 3: Enter the default gateway and DNS server settings as provided by your
ISP or enter 192.168.1.1, which is the default IP address of the CT-402.
Click OK to submit these settings and thereby activate STATIC IP mode.
NOTE: If you change the IP address of the CT-402 using the web user interface,
you must also change the IP configuration of your networked computers.

Chapter 3 Web User Interface
This chapter describes how to manage the device via the web user interface using
an Internet browser such as Microsoft Internet Explorer (version 5.0 and later).
3.1 Login Procedure
Perform the following steps to login to the web user interface.
NOTE: The default settings can be found in 2.3 Default Settings.
STEP 1: Start the Internet browser and enter http://192.168.1.1 in the web
address field. This is the default IP address for the CT-402.
NOTE: For local administration (i.e. LAN access), the PC running the browser
must be attached to the Ethernet, and not necessarily to the device.
STEP 2: A dialog box will appear, such as the one below. Enter the default
username and password and click OK to continue.
NOTE: The login password can be changed later (see section 3.7 Access Control)
STEP 3: After successfully logging in, you will reach the Device Info screen.
The web user interface is divided into three sections, the header (at top), the main
menu (at left), and the display screen (on the right). The main menu has the
following options: Device Info, Basic Configuration, and Management. Selecting
one of these will open a submenu with related options.

3.2 Device Info
The Device Info summary screen, shown below, is the default startup screen and
the first selection on the main menu. It shows the CT-402 software version.
NOTE: The software version can be changed (see section 3.5 Upgrade Firmware)
3.3 LAN Info
Click Device Info on the main menu and select LAN Info from the Device Info
submenu to display the LAN IP address and subnet mask of the CT-402.
NOTE: These values can be changed (see section 3.4 Basic Configuration)
