FCC Requirements for Telephone-Line Equipment
1. The Federal Communications Commission (FCC) has established rules which permit this
device to be directly connected to the telephone network with standardized jacks. This
equipment should not be used on party lines or coin lines.
2. If this device is malfunctioning, it may also be causing harm to the telephone network; this
device should be disconnected until the source of the problem can be determined and until
the repair has been made. If this is not done, the telephone company may temporarily
disconnect service.
3. If you have problems with your telephone equipment after installing this device, disconnect
this device from the line to see if it is causing the problem. If it is, contact your supplier or an
authorized agent.
4. The telephone company may make changes in its technical operations and procedures. If
any such changes affect the compatibility or use of this device, the telephone company is
required to give adequate notice of the changes.
5. If the telephone company requests information on what equipment is connected to their
lines, inform them of:
a. The telephone number that this unit is connected to.
b. The ringer equivalence number.
c. The USOC jack required: RJ-11C.
d. The FCC registration number.
Items (B) and (D) can be found on the unit’s FCC label. The ringer equivalence number
(REN) is used to determine how many devices can be connected to your telephone line. In
most areas, the sum of the RENs of all devices on any one line should not exceed five. If
too many devices are attached, they may not ring properly.
6. In the event of an equipment malfunction, all repairs should be performed by your supplier or
an authorized agent. It is the responsibility of users requiring service to report the need for
service to the supplier or to an authorized agent.

Certification Notice for Equipment Used in Canada
The Industry Canada label identifies certified equipment. This certification means that the
equipment meets certain telecommunications-network protective, operation, and safety
requirements. Industry Canada 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 connected 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
(extension cord). The customer should be aware that compliance with the above conditions may
not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized maintenance facility—in this
case, Black Box. Any repairs or alterations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to request the user to
disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power
utility, telephone lines, and internal metallic water pipe system, if present, are connected
together. This precaution may be particularly important in rural areas.
CAUTION: Users should not attempt to make such connections themselves, but should contact
the appropriate electric inspection authority, or electrician, as appropriate.
The LOAD NUMBER (LN) assigned to each terminal device denotes the percentage of the total
load to be connected to a telephone loop which is used by the device, to prevent overloading.
The termination on a loop may consist of any combination of devices, subject only to the
requirement that the total of the load numbers of all the devices does not exceed 100.
FEDERAL COMMUNICATIONS COMMISSION AND INDUSTRY CANADA
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate 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 communication. It 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 reasonable protection against such interference when the
equipment is operated in a commercial environment. Operation of this equipment in a residential
area is likely to cause interference, in which case the user at his own expense will be required to
take whatever measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from digital
apparatus set out in the Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le

Typical Applications Summary
Typical Applications Summary
Managing the Terminal Server
The Terminal Server can be managed and configured by administrators through various
methods, allowing them full configuration capabilities and easy access to management statistics
and tools. Administrators can access the Terminal Server using the following methods:
z Connection through ethernet using the DeviceManager, a Windows-based configuration
application.
z Connection through ethernet using WebManager, via a web browser.
z Direct connection to the serial port using a Serial Terminal or Terminal Emulation Software.
z From the network through the ethernet interface using reverse Telnet (Port 23).
z Through an SNMP agent, using the Terminal Server MIB.
Managing/Accessing devices attached to the Terminal Server
The Terminal Server can be configured to allow users or administrators to view or manage
specific devices on the Terminal Server’s serial port across the Ethernet interface using two
different methods.
z Direct Connect—users can directly connect to the device on the serial port by Telnet (Line
Service must be set to Rev Telnet) using the Terminal Server’s configured IP address and
the serial device’s assigned TCP port number.
z Easy Port Access—users can connect to the Terminal Server using the configured
Terminal Server’s IP address by reverse Telnet (port number 23), and are provided with a
device menu displaying the name of the device that the user has access to. This feature
eliminates the need for administrators and users to recall the specific port number
associated with a certain device connected to the Terminal Server. The user can simply
connect to a specific device based upon the name of the device and then return to the
device menu without disconnecting its initial reverse Telnet connection.
Network Security
The Terminal Server provides a comprehensive suite of security features to allow an organization
to implement robust security planning to prevent unauthorized access. These include trusted
host filtering and the ability to disable individual services.

Console Mode vs. Serial Mode
You will notice a little switch at the back of the Terminal Server for switching the Terminal Server
to either Console or Serial mode.
When the switch is down (ON), the Terminal Server is in Console mode; when the switch is up,
the Terminal Server is in Serial mode. Console mode is used when you have a direct connection
between a serial device (like a terminal or a PC) and the Terminal Server, accessed by the
Admin user to configure/manage the Terminal Server. You can connect directly to the Terminal
Server in Serial mode, but the Terminal Server will not display all the messages/information you
will get in Console mode. Console mode automatically sets the
Speed to 9600, Flow Control to No, Bits to 8, Stop Bits to 1, and Parity to None, in addition to
displaying extra system messages. Your Terminal Server will not work in a production
environment in Console mode.
Serial mode is used when the Terminal Server acts as a communications server, or anytime you
are not connecting directly to the Terminal Server to configure it.

Powering Up the Terminal Server
Before you attach the Terminal Server to your network or try to configure it, we suggest that you
power it up to verify that it works properly. To power up the Terminal Server, perform the
following steps:
1. Plug the external power supply into the Terminal Server and then into the electrical outlet.
2. If the Terminal Server is working correctly, you should see:
a. The Power/Ready LED starts out red.
b. The Power/Ready LED flashes green while the Terminal Server boots up.
c. The Power/Ready LED stays solid green, indicating that it is ready to configure/use.
You are now ready to begin communicating with your BLACK BOX® Terminal Server. The last
step of the installation process is to set an IP address for the Terminal Server; this is necessary
before it can be configured and put into production.
Before you start to configure the Terminal Server, you should set the Terminal Server jumpers if
you want to terminate the line.

Setting an Initial IP Address
Setting an Initial IP Address
This section describes the different methods you can use to set the Terminal Server IP address.
Following is a list of methods for setting the Terminal Server IP address and a short explanation
of when you would want to use that method:
z Easy Config Wizard—The Easy Config Wizard is automatically launched from the CD-ROM
included with your Terminal Server. You can use the Easy Config Wizard to set the
Terminal Server’s IP address and configure the line(s).
z DeviceManager—Use this method when you can connect the Terminal Server to the
network and access the Terminal Server from a Windows
Windows-based application that can be used for Terminal Server configuration and
management.
z Direct Connection—Use this method when you can connect the Terminal Server directly to
a dumb terminal, essentially logging directly into the Terminal Server. Using this method, you
will need to configure and/or manage the Terminal Server using either the Menu or CLI.
z DHCP/BOOTP—Use this method when you have a BOOTP or DHCP server running and
you can connect the Terminal Server to your network. The Terminal Server will automatically
obtain an IP address from a local network DHCP/BOOTP server when it is booted up the first
time and will continue to obtain it’s IP address from the DHCP/BOOTP server unless the
DHCP/BOOTP Service is disabled.
z ARP-Ping—Use this method when you can connect the Terminal Server to the network and
want to assign a temporary IP address to the Terminal Server by specifying an ARP entry
and then pinging it.
z IPv6 Network—When the Terminal Server is connected to an IPv6 network, its local link
address should automatically be recognized by the network.

Note: Regardless of which method you use, the Terminal Server must reside within the same
network as the host you are accessing it from.
Once an IP address has been assigned to the Terminal Server, in most cases, you can continue
to use the same method to configure and/or manage the Terminal Server. See
Configuration Methods on page 37 for more information on the different methods you can use
to manage/configure the Terminal Server.
Using DeviceManager
To use the DeviceManager, you must first install it on a Windows 98/2000/NT/ME/Server
2003/XP operating system (Windows NT requires Service Pack 4 or later) that resides in the
same network as the Terminal Server. The DeviceManager installation wizard can be found on
the CD-ROM included in the Terminal Server package.
1. Connect the Terminal Server to the LAN and plug it in; it will automatically boot up.
2. From the CD-ROM that was included in the Terminal Server packaging, select the
DeviceManager link.
3. Click on the link under Location and click Open to automatically start the DeviceManager
installation.
4. Install the DeviceManager by following the installation wizard. On the last window, check the
Yes, I want to launch DeviceManager now. box and click the Finish button.
5. On the Manage Device Server tab, click the Search Local Network button.

Using a Direct Connection
You can connect to the Terminal Server using a PC with a terminal emulation package, such as
HyperTerminal or a terminal.
1. Connect the Terminal Server to your PC or dumb terminal. Make sure the dip switch is in
Console mode (this sets the Terminal Server serial port to EIA-232). When connecting a
terminal or PC directly (without modems), the EIA-232 signals need to be crossed over (‘null
modem’ cable). See
2. Using a PC emulation application, such as HyperTerminal, or from a dumb terminal, set the
Port settings to 9600 Baud, 8 Data bits, No Parity, 1 Stop Bits, and No Hardware Flow
control to connect to the Terminal Server.
3. When prompted, type admin for the User and superuser for the Password. You should now
see the
4. You are now logged into the Terminal Server and can set the IP address by typing from the
command line using the Command Line Interface (CLI):
Where ipv4address is the IP Address being assigned to the Terminal Server.
5. Type the following command:
6. If you are going to use another configuration method, such as WebManager or
DeviceManager, unplug the Terminal Server. Change the Terminal Server dip switch to Off
Serial (dip switch in the up position) and connect it to your serial device. Plug the Terminal
Server back in, automatically rebooting the Terminal Server in the process.
7. If you want to complete the configuration using a direct connection, see Chapter 3,
Configuration Methods on page 37 and/or Chapter 6, Command Line Interface on page
83. After you complete configuring the Terminal Server, unplug the Terminal Server. Change
the Terminal Server dip switch to Off Serial (dip switch in the up position) and connect it to

Using DHCP/BOOTP
If you are using BOOTP, you need to add an entry for the Terminal Server that associates the
MAC address (found on the back of the Terminal Server) and the IP address that you want to
assign to the Terminal Server. Next, connect the Terminal Server to the network and plug it in to
turn it on.
If you are using DHCP, just connect the Terminal Server to the network and plug it in to turn it on.
View the DHCP server’s IP address table to see what IP address was assigned to the Terminal
Server.
You are now ready to configure the Terminal Server. See Chapter 3, Configuration Methods on
page 37 for information on the different Terminal Server configuration methods.

Using ARP-Ping
You can use the ARP-Ping (Address Resolution Protocol) method to temporarily assign an IP
address and connect to your Terminal Server to assign a permanent IP address. To use
ARP-Ping to temporarily assign an IP address:
1. From a local UNIX/Linux host, type the following:
arp -s a.b.c.d aa:bb:cc:dd:ee:ff
On a Windows® 98 or newer system, type the following:
arp -s a.b.c.d aa-bb-cc-dd-ee-ff
(where a.b.c.d is the IPv4 address you want to temporarily assign to the Terminal Server,
and
back of the unit.
2. Whether you use UNIX or Windows®, you are now ready to ping to the Terminal Server.
Here is a UNIX example of the sequence to use:
arp -s 192.168.209.8 00:80:d4:00:33:4 e
ping 192.168.209.8
You are now ready to configure the Terminal Server. See Chapter 3, Configuration Methods on
page 37 for information on the different Terminal Server configuration methods.
Setting an Initial IP Address
aa:bb:cc:dd:ee:ff is the Ethernet (MAC) address of Terminal Server, found on the
IPv6 Network
The Terminal Server has a factory default link local IPv6 address that takes the following format:
Terminal Server MAC Address: 00-80-D4-AB-CD-EF
Link Local Address: fe80::0280:D4ff:feAB:CDEF
The Terminal Server will also listen for IPv6 router advertisements to learn a global address. You
do not need to configure an IPv4 address for a Terminal Server residing in an IPv6 network.
You are now ready to configure the Terminal Server. See Chapter 3, Configuration Methods on
page 37 for information on the different Terminal Server configuration methods.
