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
