Radio and TV Interference
This equipment generates and uses radio frequency energy, and if not installed and used properly—that is, in
strict accordance with the manufacturer's instructions—may cause interference to radio and television recep-
tion. This equipment has been tested and found to comply with the limits for a Class A computing device in
accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reason-
able protection from such interference in a commercial installation. However, there is no guarantee that inter-
ference will not occur in a particular installation. If the equipment causes interference to radio or television
reception, which can be determined by disconnecting the cables, try to correct the interference by one or more
of the following measures: moving the computing equipment away from the receiver, re-orienting the receiving
antenna, and/or plugging the receiving equipment into a different AC outlet (such that the computing equip-
ment and receiver are on different branches).
Industry Canada Notice
This equipment meets the applicable Industry Canada Terminal Equipment Technical Specifications. This is
confirmed by the registration number. The abbreviation, IC, before the registration number signifies that regis-
tration was performed based on a Declaration of Conformity indicating that Industry Canada technical speci-
fications were met. It does not imply that Industry Canada approved the equipment.
This Declaration of Conformity means that the equipment meets certain telecommunications network protec-
tive, operational and safety requirements. The Department does not guarantee the equipment will operate to
the user's satisfaction. Before installing this equipment, users should ensure that it is permissible to be con-
nected to the facilities of the local telecommunications company. The equipment must also be installed using
an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line
individual service may be extended by means of a certified connector assembly (telephone extension cord). The
customer should be aware that compliance with the above condition may not prevent degradation of service in
some situations. Repairs to some certified equipment should be made by an authorized maintenance facility
designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment mal-
functions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the ground connections of the power utility, telephone lines
and internal metallic water pipe system, are connected together. This protection may be particularly important
in rural areas

LB510A Getting Started Guide 1 • General Introduction
LB510A Overview
The Black Box Model LB510A G.SHDSL NTU provides high speed 2-wire connectivity to ISPs, PTTs, and
enterprise environments using Symmetrical High-data-rate Digital Subscriber Line (G.SHDSL) technology.
The Model LB510A provides a 10/100BaseT Ethernet interface on a shielded RJ-45 jack, the DSL on an RJ-
11 jack, and the RS-232 console port on an RJ-45 jack.
As a symmetric, full-duplex NTU, the DSL offers equal data rates in both directions over a single twisted pair
using TC-PAM modulation. Line connection is made through the RJ-11 jack. Standard versions of Model
LB510A are powered by a UI (universal 100–240 VAC) supply.
Figure 1. Model LB510A
Features
•Symmetrical high data-rate DSL (G.SHDSL)
•Data rates up to 4.6Mbps in 64-kbps intervals
•10Base-T/100Base-TX Ethernet interface
•RS-232 console port for management and configuration
•Built-in testing and diagnostics
•Plug ‘n’ Play for easy installations
•Interoperable with other Black Box G.SHDSL modems
•Configurable as remote (CP) units
•Configurable as central (CO) units to operate back-to-back
•Front-panel status indicators
•CE marked

Introduction 17
LB510A Getting Started Guide 2 • Initial Configuration
Introduction
The Model LB510A (see figure 2) has two configuration modes: RS-232 console and web page GUI software.
Figure 2. Model LB510A
The RS-232 console is used for the initial configuration of the IP address and mask. Subsequently the easiest
method is to use a standard web browser to complete the configuration.
Power up the NTU
Your NTU comes with an external AC adaptor with detachable power cord. (Also refer to “Power-up” on
page 32.)
AC power-up
1. Connect female plug of the AC power cord to the AC adaptor provided.
2. Connect the barrel-type connector of the AC adaptor to the barrel-type power jack on the
G.SHDSL NTU.
3. Insert the male plug of the AC power cord into an AC power outlet (100–240 VAC).
Power-up indication
The Power and 100M Ethernet LEDs are lit while the G.SHDSL NTU is powering up.
Configure the IP address
The G.SHDSL NTU is shipped with a factory-configured IP address assigned to the Ethernet LAN port
(green outline). The address is 192.168.200.10/24 . In most cases, you must change the address to be on the
same subnet as your PC, as described in the procedures below. If you are not sure which IP address to use for
your installation, contact your network administrator.
Ensure that the power cable used with the external power adapter meets all
applicable standards for the country in which it is to be installed, and that it is
connected to a wall outlet which has earth ground.
WARNING

LB510A Getting Started Guide 2 • Initial Configuration
Connect a PC and log in
Using the included combination RS-232/Ethernet cable and DB9-RJ45 adapter, connect a PC’s serial port to
the NTU ’s Console port (red outline) (see figure 3).
Figure 3. Connecting G.SHDSL NTU to the PC’s serial port
1. Start a HyperTerminal session on the PC using the settings:
9600 bps, 8 data bits, no parity, 1 stop bit, no flow control
2. Log in to the G.SHDSL NTU using the factory-default login (superuser) and password (superuser):
Login: superuser

——————————————————————————
2. Modify the IP address for the LAN port according to your network requirements.
ip set interface ip1 ipaddress 10.10.4.10 255.255.255.0
Note The above IP address (10.10.4.10/24) is only an example. You must choose
an IP address on the same subnet as your PC.
3. Verify the new address is correct and save it in system boot memory.

The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.

LB510A Getting Started Guide 2 • Initial Configuration
Connect to the local IP network
Now you can connect the G.SHDSL NTU to your local IP network and complete the remaining configura-
tion from your PC using a standard web browser.
Connect the G.SHDSL NTU’s Ethernet port (green) to the same Ethernet segment as your PC (see figure 4).
The front-panel Ethernet Link LED should turn on. If it does not, press the rear-panel MDI-X switch so that
the Ethernet Link LED illuminates.
You can check the connection with the ping command. For example shown in figure 4, you would ping
10.10.4.10 from a PC on the IP network.

Log onto the web management interface
You will now access the web management graphical user interface (GUI) to configure the G.SHDSL NTU
using a standard web browser (such as Netscape Browser, Mozilla Firefox, or Internet Explorer).
1. At your PC, open a web browser and enter the IP address you assigned to the NTU’s Ethernet LAN port
in step 2 of section “Modify the IP address” on page 18. (In this example, 10.10.4.10.) (see figure 5)

LB510A Getting Started Guide 2 • Initial Configuration
Connect the G.SHDSL port
3. Obtain single-twisted-pair cable with an RJ-11 plug connector at each end.
4. Plug one end of the cable into the (yellow) RJ-11 socket (labelled Line) on the G.SHDSL NTU.
(See figure 6.)
5. Plug the other end of the cable into the RJ-11 wall socket that provides your G.SHDSL service.
6. Go to G.SHDSL > Configuration to configure the DSL port parameters.
Note If two G.SHDSL NTUs are connected back-to-back, one must be config-
ured as Remote, the other as Central.
7. The WAN Link LED will flash while in the process of establishing a link. The LED will be on constantly
once a valid DSL connection is established.
