console can be any PC that can run a terminal emulator (such as Tera Term Pro).
BSGX4e Business Gateway Installation Guide 16
Release 01.01 NN47928-303
Page 17
The following cables are required to install the BSGX4e:
Serial cable To connect the CONSOLE port (DB9 connector) to a terminal (DB9 or
Universal Serial Bus (USB) connector, depending on the terminal).
RJ45 to
RJ45 cables
To connect the Ethernet ports to the WAN and to the LAN devices,
CAT5E or better is recommended.
NOTE: The cables can be straight or crossover. The BSGX4e ports
automatically determine if pairs need to be crossed over.
RJ11 to
RJ11 cables

NN47928-303 Release 01.01
Page 18
After the BSGX4e is physically installed into the network, network connections are
initialized. If a Dynamic Host Configuration Protocol (DHCP) service is working
properly on the WAN, the BSGX4e receives its IP addressing information from the
DHCP server. This process occurs automatically as soon as the BSGX4e is connected
to the WAN.
However, if DHCP service is not available or not working properly, you can enter IP
addressing information manually. At a minimum, you need to enter the IP address
for the eth0 WAN interface, the default gateway address, and the Domain Name
System (DNS) server address. Table 5 includes blank spaces to record this minimum
information.
After the WAN network connection is established, you can configure other ports and
servers at the console or through a remote connection to the BSGX4e through the
WAN or from a workstation in the LAN. For complete configuration information, see
the BSGX4e Business Gateway User Guide on the Documentation CD.

the unit.
1. Connect the labeled 12V DC on the back panel of the BSGX4e. See Figure 4 on
page 18.
2. Connect the AC plug to the appropriate AC receptacle (power cord or outlet).
3. Ensure that the LED labeled STATUS on the front panel is lit green. If not,
ensure that the power connections are secure and that the outlet has power.
Connecting LAN devices
Repeat these steps for each LAN port on the BSGX4e that you want to connect to a
LAN device (such as a PC or a VoIP phone).
1. Connect one of the connectors of an RJ45 to RJ45 ethernet cable to one of the
four LAN connectors (labeled 4, 3, 2, 1) on the back panel of the BSGX4e. See
Figure 4 on
The cables can be straight or crossover. The LAN switch automatically determines
if pairs need to be crossed over.
page 18.
2. Connect the RJ45 connector on the other end of the cable to the LAN port of
the device to which you want to connect.
You can connect any LAN device to any LAN port, including workstations, VoIP
telephones, and patch panels.
3. Ensure that the corresponding LAN LED on the front panel is lit green. If it is
not, ensure that the cable connectors are locked and secure in their ports.
Connecting the WAN
These steps connect the BSGX4e to the WAN.
1. Connect one of the connectors of an RJ45 to RJ45 Ethernet cable to the WAN
connector on the back panel of the BSGX4e. See Figure 4 on
The cable can be straight or crossover. The WAN port automatically determines if
pairs need to be crossed over.
2. Connect the RJ45 connector on the other end of the cable to the service
provider demarcation point. This point is usually an access router that
connects the network to the WAN.
3. Ensure that the WAN LED on the front panel is lit green. If it is not, ensure that
the cable connectors are locked and secure in their ports.

NN47928-303 Release 01.01
Page 20
Connecting an optional analog device
These steps connect the BSGX4e FXS port to an analog telephone or fax device. (This
procedure is optional; the BSGX4e can control a LAN without an analog device.)
CAUTION: Do not connect the PHONE port to the CO Public Switched Telephone
Network (PSTN) phone line.
1. Connect one of the connectors of an RJ11 to RJ11 cable to the port labeled
PHONE on the back panel of the BSGX4e. See Figure 4.
2. Connect the RJ11 connector on the other end of the cable to the analog
device.
3. Put the analog device into an off-hook state (for example, lift the handset of
an analog phone). While the analog device is off-hook, check that the LED
labeled PHONE on the front panel of the BSGX4e is lit green. If it is not, ensure
that the device is off-hook and that both ends of the cable are securely
connected.
4. Return the analog device to its on-hook state. The PHONE LED is no longer lit.
Connecting the lifeline
These steps connect the BSGX4e FXO port to the CO line (PSTN) to act as a
telephone lifeline when VoIP phone service is not available. (VoIP service is not
available when the WAN connection or the required servers are not available.)
1. Connect one of the connectors of an RJ11 to RJ11 cable to the port labeled
LINE on the back panel of the BSGX4e. See Figure 4 on
page 18.
2. Connect the RJ11 connector on the other end of the cable to the CO (PSTN)
phone line.
3. The LED labeled LINE on the front panel of the BSGX4e is not lit unless the CO
(PSTN) phone line is off-hook. The BSGX4e uses this line only when VoIP
service is unavailable, and the BSGX4e switches to Local Call Routing mode.
Verification of the LINE connection requires a debug command, and so it can only
be performed later in the install procedure, after you log on to the BSGX4e
(described in Logging on to the BSGX4e (page 21)).
To verify the LINE connection, enter these commands:
ICAD> debug enable
ICAD> dshow interface fxo
If the LINE (FXO) is connected, but idle, the unit responds:
FXO Port Status:
Port Status
-----------------------------------------0-0 IDLE

Otherwise, if the FXO port is disconnected, the unit responds:
FXO Port Status:
Port Status
-----------------------------------------0-0 DISC_ERROR
To leave debug mode, enter:
ICAD> debug disable
Connecting a console
These steps connect a console to the BSGX4e unit so that you can initialize the
network connection. After the console is connected, you can log on and enter
commands, as described in the following sections.
Use any PC capable of running a terminal emulator such as Tera Term Pro.
1. Connect the DB9 connector of a serial cable to the port labeled CONSOLE on
the back panel of the BSGX4e. See Figure 4.
2. Connect the other end of the serial cable to the console.
Depending on the console, the connection can be to a DB9 port or a USB port.
3. There is no CONSOLE LED. To verify the connection, attempt to log on as
described in the following section.
Logging on to the BSGX4e
The following steps describe how to log on to the BSGX4e unit from a console
terminal connected to the CONSOLE port of the BSGX4e. Use the same log on
procedure from a remote terminal with a WAN network connection.
1. Power on the console and start the terminal session. The terminal emulator
must use the following settings for the session:
n 9600 baud
n 8 data bits
n no parity

Initializing the WAN connection
This section assumes that the BSGX4e unit is physically installed and that a terminal
session from the console has successfully logged on to the unit. The final step in the
BSGX4e installation is the initialization of the WAN network connection.
As described in the section Getting network information (page 17), if the DHCP
service is working properly on the WAN, the BSGX4e receives its IP addressing
information automatically from the DHCP server. Thus, the first step is to ensure
that the BSGX4e has the necessary IP addresses.
If the BSGX4e did not receive its IP addresses automatically, you need to manually
enter the addresses. This minimum network information is listed in Table 5 (page
18).
IP Address/Mask for eth0
1. To check that the unit received the IP address and subnet mask for its WAN
interface (called eth0 for Ethernet interface 0), enter:
23 BSGX4e Business Gateway Installation Guide
NN47928-303 Release 01.01
Page 24
ICAD> show interface ip eth0
The unit responds with a display similar to the following:
“eth0” info:
Interface eth0

2. Look at the IP Address/Mask line. It shows the address and mask assigned to
the eth0 (WAN) interface. If the address is correct, skip to the procedure
Default Gateway Address (page 25).
3. If the address is incorrect or unspecified (0.0.0.0), look at the DHCP line. It
shows whether the DHCP client is enabled (on) or disabled (off). If the DHCP
client is on, but the IP address is 0.0.0.0, the DHCP service is not working for
the unit.
4. To manually enter the correct IP address and subn et mask, the DHCP client
must be disabled (off). To disable the DHCP client, enter this command:
ICAD> config interface ip eth0 dhcp no
5. Then, to manually enter the eth0 IP address and subnet mask, enter:
ICAD> config interface ip eth0 address/mask
Specify the address and mask with dotted-decimal or Classless Inter Domain
Routing (CIDR) notation (for example, 192.168.15.33/255.255.255.0 or
192.168.15.33/24).
6. To verify the entry of the address and mask, enter the show command again:
*ICAD*> show interface ip eth0
Assuming that the DHCP client is off, the unit responds with a display similar
to the following:

192.168.1.0 192.168.1.1 255.255.255.0 eth1
2. Look at the route with the Destination 0.0.0.0 and Netmask 0.0.0.0. The
address shown under Gateway is the default gateway address. If the address is
correct, skip to the procedure DNS Server (page 25).
3. If the address is incorrect or the table does not have a default route, enter the
correct default gateway address:
*ICAD*> config route table default gw address
4. To verify that the new default route is correct, enter the show command
again:
*ICAD*> show route table
DNS Server
1. To check that the unit has the address of a DNS server, enter:

*ICAD*> show system dns
5. To save the changes to the configuration, enter:
*ICAD*> save
Verifying the WAN connection
To verify that the BSGX4e unit is connected to the network, try a simple ping test. If
the BSGX4e includes the network information described in Initializing the WAN
connection (page 23) (its eth0 IP address, the default gateway address, and a DNS
server), a ping from the BSGX4e can reach a network location. An example follows:
To ping the network location www.yahoo.com, enter:
ICAD> ping www.yahoo.com
If the connection is successful, the ping responds with messages similar to the
following:
Pinging www.yahoo.com (68.142.197.87): 56 data bytes
Reply from 68.142.197.87: bytes=56 icmp_seq=0 time=50ms
Reply from 68.142.197.87: bytes=56 icmp_seq=1 time=50ms
Reply from 68.142.197.87: bytes=56 icmp_seq=2 time=50ms
Reply from 68.142.197.87: bytes=56 icmp_seq=3 time=50ms
----- www.yahoo.com ping statistics ----4 packets transmitted, 4 packets received, 0.0% packet loss
Round-trip times: min/avg/max=50/50/50ms
If the ping to a network location is not successful, ensure that the BSGX4e can
reach the access router. To do this check, ping the default gateway address.
To see the default gateway address, look at the default route in the route table
(Destination 0.0.0.0). For example:
ICAD> show route table
Destination Netmask Gateway Interface
-------------------------------------------------------------
0.0.0.0 0.0.0.0 66.206.164.193 eth0
ICAD> ping 66.206.164.193
If the ping to the gateway address is successful, it verifies that the BSGX4e is
well connected to the access router. If the ping to the gateway address is not
successful, ensure that the address is correct and that the WAN LED is lit.
After you connect the unit to the network, you can remotely configure the unit. For
information on all configuration options, see the BSGX4e Business Gateway User
Guide.

This appendix describes how to view the current settings in the BSGX4e unit and how
to restore the unit to its factory default settings.
Viewing current settings
This section describes how to view the current settings of the BSGX4e unit.
Viewing user accounts
The BSGX4e uses two predefined user accounts: nnadmin and user.
The user account nnadmin has read and write access and can change the current
settings by using commands such as config.
The user account user can only perform read operations, such as stat to display
statistics. (The only change that the user account user can make is to change the
password for the account.)

For more information about user accounts and user management, see the BSGX4e
Business Gateway User Guide.
Viewing configuration
The BSGX4e provides several show commands that show various configuration
settings. These commands are described in the BSGX4e Business Gateway User
Guide. To get a full listing of the current configuration, enter:
ICAD> dump
The unit responds with a full configuration listing.
Page 28
Note: To see an example configuration listing and information on all
configuration settings, see the BSGX4e Business Gateway User Guide.
Restoring default settings
Restoring the BSGX4e to its factory settings can be necessary for troubleshooting or
significant system changes.
After the unit is restored to default settings:
All existing and previous configurations are erased; the only configuration that
remains contains the original factory settings.
All user accounts are erased, except the two predefined users nnadmin and user.
Note: After the factory default settings are restored, the default passwords for
nnadmin and user are also restored. Change the default passwords
immediately (see Logging on to the BSGX4e (page 21)).
After the unit is restored to default settings, you can access them through:
n The console port.
n A workstation on the LAN through the eth1 interface. The default eth1 address
is 192.168.1.1.
n A workstation on the WAN if DHCP assigns an address to eth0. (DHCP service is
enabled for eth0 by default.)
Restore the BSGX4e factory default settings using:
the RELOAD button on its back panel.
the Defaults button on the Operations menu in the Web User Interface (UI).
the erase command from the Command Line Interface (CLI).
Reload Button
Reset the BSGX4e unit to its initial factory configuration by pressing the recessed
RELOAD button on its back panel (see Figure 5). Use a pen to push in the RELOAD
button; press the button for at least five seconds.
If a terminal session is logged on to the unit when its reload button is pressed,
information about the reload and restart is sent to the session. The information is
the same as the erase command (see Erase Command (page 30)).

Page 30
The IP address of the LAN (eth1) interface restores to its default, 192.168.1.1.
The IP address of the WAN (eth0) interface restores to its default, 0.0.0.0. DHCP
service activates by default for the eth0 interface so an IP address can be
assigned by DHCP.
To reconnect from the LAN, enter the IP address of the eth1 interface (192.168.1.1)
on the browser entry line. If the browser cannot connect to the default address, the
default address must be reconfigured from the eth0 interface or from the console.
Erase Command
You can restore the default configuration from a terminal session using the erase
command in the CLI. The procedure for starting a terminal session is described in
"Log on to the BSGX4e" on page 21.
Note: When you restore the unit to factory default settings, any remote
connections to the unit are lost. The eth1 interface is assigned the default
IP address 192.168.1.1; the eth0 interface does not have a default IP
address, although DHCP service is enabled by default, so an IP address can
be assigned by DHCP.
1 To erase the current configuration and return the unit to its initial factory
configuration, enter:
ICAD> erase
The unit responds:
The system will reboot automatically after erasing the
configuration.
Are you sure you wish to erase the configuration [y/N]:
