Table 2: Serial Port Configuration

Px 6/2 Expander Installation Guide
7 Port Expander Configuration
Much like an Allworx phone, the Port Expander gets its configuration information and software updates from
the Allworx server. Therefore, the Network port of the Allworx Px 6/2 must be attached either directly or
remotely to an Allworx server. This is usually done by connecting to the server LAN through a network switch. .
Up to three Port Expanders can be connected to a given server. The diagram below depicts three Port
Expanders connected on a server LAN. When connected this way, the Port Expanders require no manual
configuration steps.
Figure 4, Connection Diagram
7.1 Configuring the Port Expander Password
Although connecting the Port Expander normally does not require any manual configuration, the need to
configure the Port Expander’s settings may arise in the future. Such situations can be made more convenient
by setting the Port Expander’s password during installation.
For security reasons, Allworx Px 6/2 Port Expanders do not have a default password. A site-specific password
must be created and entered using the Port Expander’s Configuration web page. Do this using the following
procedure:
1. If the Port Expander has already been powered on, disconnect power.
2. If a cable is plugged into the Network port, disconnect it.
3. Set up the PC’s network interface to obtain an IP address automatically (using DHCP).
4. Apply power to the Port Expander.
5. Wait until the power and port LEDs light solid amber (about 45 seconds). Connect the PC’s network port to
the Port Expander’s Network port with a standard RJ-45 category 5 Ethernet cable.

6. Verify that the PC has an IP address on the 192.168.2.xxx network.
You may need to release and renew the PC’s IP address using the ipconfig command in a command
window to get an address from the Port Expander.
7. Open a web browser on the PC and enter http://192.168.2.254 into the browser’s address field.
The Port Expander’s Configuration screen is displayed.
8. Scroll to the New Password field. Enter the site’s new Port Expander administrator password. Re-enter the
password in the Confirm Password field.
9. Click Update
The Port Expander’s Update Result screen is displayed.
10. Disconnect the network cable from the Port Expander’s Network port. Connect the Port Expander to the
system using the procedure in either Section 7.2, Local Connection or Section 7.3, Remote Connection.
11. Save the password for future reference. If the password is lost or forgotten, it can be reset by repeating this
procedure and entering a new password.
7.2 Local Connection
When properly connected to the server LAN, the Allworx Px 6/2 will be configured automatically. This should
require no manual steps, although it is recommended that the password be set in accordance with the
procedure, above. To ensure the automatic configuration is successful, perform the following steps:
1. If the Port Expander has already been powered on, disconnect power.
2. Connect the Network port of the Port Expander to the LAN of the Allworx server per the diagram above
using a standard RJ-45 category 5 Ethernet cable.
3. Apply power to the Port Expander.
4. Observe the Power LED. During power up, it will flash green. When the LED stops flashing and shines
solid green, the Port Expander has received any software updates and has been configured. This may take
as long as five (5) minutes. It is now ready for CO lines and analog phones to be connected to its FXO and
FXS ports.
5. If the Power LED does not shine solid green within five (5) minutes. Unplug and re-plug the Port
Expander’s power adapter.
6. Activate the FXO and FXS ports through the Web Admin page on the Allworx Server. Refer to the Allworx
System Administrator’s Guide, Release 6.9 or higher for information on configuring the ports.

7.3 Remote Connection
Allworx Px 6/2 Port Expanders can be configured to run at sites that are remote to the Allworx server. Much
like with a remote Allworx phone, this requires manual configuration of the Port Expander. The Boot Server IP
(the Allworx Server’s IP) and the server’s Plug and Play Secret Key must be entered within the Port
Expander’s configuration interface. In addition, forwarding of ports through intervening firewalls may be
required. See the Allworx System Administrator’s Guide, Release 6.9 for instructions for configuring firewalls.
Caution: Correct routing of 911 emergency calls for analog handsets attached to remote Allworx Port
Expanders cannot be guaranteed. Do not use the Px’s FXS ports for handsets from which
placing 911 calls may be attempted.
Caution: If the network connection between the Port Expander and the Allworx server is interrupted,
regular use of the Port Expander’s FXO and FXS ports will not be possible. The only option
for placing calls through a Port Expander that does not have a functional network
connection to its Allworx server is to plug an analog phone into the Power Fail port. Calls
placed using this phone will be routed to the CO line connected to FXO port 1. No other
ports will be functional.
To configure the Boot Server IP and Plug and Play Secret Key, perform the following steps:
1. Access the Port Expander’s Configuration screen by performing Steps 1 through 7 of the procedure in
Section 7.1, Configuring the Port Expander Password.
2. Navigate to the Boot Server IP Address field. Enter the IP address of the Allworx Server to which the Port
Expander will be associated.
3. Navigate to the Plug and Play Secret Key field. Enter the Allworx Server’s Secret Key. To determine the
server’s Secret Key, see the Allworx System Administrator’s Guide, Release 6.9 for instructions.
4. Re-enter the key in the Confirm Plug and Play Secret Key field.
5. If the Port Expander’s administrator password has not been set, scroll to the New Password field. Create a
site-specific password and enter it into the New Password field. Re-enter the password in the Confirm
Password field.
6. Click Update
The Port Expander’s Update Result screen is displayed.
7. Click Restart
8. Connect the Network port of the Port Expander to the site’s network using a standard RJ-45 category 5
Ethernet cable.
Note: A network path to the Allworx Server must be available.
9. Observe the Power LED. During power up, it will flash green. When the LED stops flashing and shines
solid green, the Port Expander has received any software updates, and has been fully configured. This
