1.1 Overview

The PMG1005-T20B SFU (Single Family Unit) combines a fiber optic GPON (Gigabit Passive Optical
Network) ONT (Optical Network Terminal) with a built-in 1-port Gigabit Ethernet switch. Your GPON
Device provides shared Internet access through a fiber optic line connected to the PON port’s built-in
optical transceiver.

Figure 1 GPON Device Providing Internet Access

CHAPTER 1

Introduction

1.2 Managing the GPON Device

Use the GPON Device’s built-in Web Configurator to manage it. You can connect to it using a web
browser such as Firefox or Internet Explorer. The Web Configurator gives you access to all the available
settings for this product. For details on connecting to it, see the Section 2.1.1 on page 11.

1.3 Good Habits for Managing the GPON Device

Do the following things regularly to make the GPON Device more secure and to manage the GPON
Device more effectively.

• Change the web configurator login password. Use a password that’s not easy to guess and that
consists of different types of characters, such as numbers and letters.

• Write down the password and put it in a safe place.

• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working
configuration may be useful if the GPON Device becomes unstable or even crashes. If you forget
your password, you will have to reset the GPON Device to its factory default settings. If you backed up
an earlier configuration file, you would not have to totally re-configure the GPON Device. You could
simply restore your last configuration.

device.

1.5 The Reset Button

If you forget your password or cannot access the Web Configurator, you will need to use the RESET
button at the back of the GPON Device to reload the factory-default configuration file. This means that
you will lose all custom configuration and the password will be reset to the default.

1.5.1 Using the Reset Button

1 Make sure the POWER LED is on (not blinking).

2 To set the GPON Device back to the factory default settings (LAN IP address 192.168.1.1, user name

admin and password 1234), press the RESET button for more than three seconds and then release it. The
LEDs flash and the GPON Device restores the defaults and restarts.

Note: Press the RESET button for less than one second to restart the GPON Device without

changing it back to the factory default settings.

1.6 Wall Mounting

You may need screw anchors if mounting on a concrete or brick wall.

Note: The screws and screw anchors are not included.

Table 3 Wall Mounting Information

M4.2 Screws Two

Screw anchors (optional) Two

1 Select a position free of obstructions on a wall strong enough to hold the weight of the device.

2 Mark two holes on the wall at the appropriate distance apart for the screws.

Chapter 1 Introduction

Be careful to avoid damaging pipes or cables located inside the wall
when drilling holes for the screws.

3 If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into the full

depth of the holes, then insert the screws into the anchors. Do not insert the screws all the way in - leave
a small gap of about 0.5 cm.

If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the screws all
the way in - leave a gap of about 0.5 cm

4 Make sure the screws are fastened well enough to hold the weight of the GPON Device with the

connection cables.

5 Align the holes on the back of the GPON Device with the screws on the wall. Hang the GPON Device on

the screws.

CHAPTER 7

Troubleshooting

7.1 Overview

This chapter offers some suggestions to solve problems you might encounter. The potential problems are
divided into the following categories.

• Power, Hardware Connections, and LEDs

• GPON Device Access and Login

• Internet Access

7.2 Power, Hardware Connections, and LEDs

The GPON Device does not turn on. None of the LEDs turn on.

1 Make sure the GPON Device is turned on.

2 Make sure you are using the power adapter or cord included with the GPON Device.

3 Make sure the power adapter or cord is connected to the GPON Device and plugged in to an

appropriate power source. Make sure the power source is turned on.

4 Turn the GPON Device off and on.

5 If the problem continues, contact the vendor.

One of the LEDs does not behave as expected.

1 Make sure you understand the normal behavior of the LED. The PON LED turns off if the optical

transceiver has malfunctioned or the fiber cable is not connected or is broken or damaged enough to
break the PON connection. See Section 1.4 on page 7 for details about the other LEDs.

2 Check the hardware connections. See the Quick Start Guide for details.

3 Inspect your cables for damage. Contact the vendor to replace any damaged cables.

4 Turn the GPON Device off and on.

5 If the problem continues, contact the vendor.

7.3 GPON Device Access and Login

I forgot the IP address for the GPON Device.

1 The default IP address is 192.168.1.1.

2 If you changed the IP address and have forgotten it, reset the GPON Device to its factory defaults. See

Section 1.5 on page 8.

I cannot see or access the Login screen in the Web Configurator.

1 Make sure you are using the correct IP address.

• The default IP address is 192.168.1.1.

• If you changed the IP address, use the new IP address.

• If you changed the IP address and have forgotten it, reset the GPON Device to its factory defaults.
See Section 1.5 on page 8.

2 Check the hardware connections, and make sure the LEDs are behaving as expected. See Section 1.4

on page 7.

3 Make sure your computer’s IP address is in the same subnet as the GPON Device.

4 Make sure your Internet browser does not block pop-up windows and has Javascript and Java enabled.

5 Reset the GPON Device to its factory defaults, and try to access the GPON Device with the default IP

address. See Section 1.5 on page 8.

6 If the problem continues, contact the network administrator or vendor.

I can see the Login screen, but I cannot log in to the GPON Device.

1 Make sure you have entered the user name and password correctly. The default user name is shown on

the cover page of this User’s Guide. These fields are case-sensitive, so make sure [Caps Lock] is not on.

2 You cannot log in to the Web Configurator while someone is using Telnet to access the GPON Device.

Log out of the GPON Device in the other session, or ask the person who is logged in to log out.

3 Turn the GPON Device off for ten seconds and then back on.

PMG1005-T20B User’s Guide

4 If this does not work, you have to reset the GPON Device to its factory defaults. See Section 1.5 on page

8.

7.4 Internet Access

I cannot access the Internet.

1 Check the hardware connections, and make sure the LEDs are behaving as expected.

The PON LED turns off if the optical transceiver has malfunctioned or the fiber cable is not connected or
is broken or damaged enough to break the PON connection.

The LOS LED turns red if the GPON Device is not receiving an optical signal.
The LOS LED turns blinking red if the GPON Device is receiving a weak optical signal.

See Section 1.4 on page 7 for details about the other LEDs.

Chapter 7 Troubleshooting

2 Make sure you entered the ISP account information correctly in your computer. These fields are case-

sensitive, so make sure [Caps Lock] is not on.

3 Disconnect all the cables from your GPON Device (refer to the Quick Start Guide).

4 Turn the GPON Device off and on.

5 If the problem continues, contact the ISP.

I cannot access the Internet anymore. I had access to the Internet (with the GPON Device), but
my Internet connection is not available anymore.

1 Check the hardware connections, and make sure the LEDs are behaving as expected. The PON LED

turns off if the optical transceiver has malfunctioned or the fiber cable is not connected or is broken or
damaged enough to break the PON connection. See Section 1.4 on page 7 for details about the other
