Px 6/2 Expander FAQ's

-My Allworx Px 6/2 Expander won’t Plug and Play. What’s wrong?

Check that the site's Allworx server is running System Software Release

6.9.2.1 or higher and that the server has the Allworx Internet Call Access

Feature key. If the server is not running an appropriate system software

release, upgrade it. See the Allworx System Administrator's Guide (6.9.2.1

or higher) for instructions. If both server requirements have been met and

the Px still does not plug and play, there are other possible causes. These

are described below:

Site is using a non-Allworx DHCP server – If a device other than the

site's Allworx server is being used as the network's DHCP server, the Px

may fail to plug and play. If the DHCP server uses DHCP Option 66, then

you must set the TFTP Server IP Address value in the DHCP server's

database. Set it to be the same as the LAN IP Address of the Allworx

server. If the site's DHCP server does not support DHCP Option 66, the

Px's network settings must be configured manually. In that case, perform

procedure B, below.

If the site's DHCP server uses DHCP Option 66 but the Px does not plug

and play after setting the TFTP Server IP Address, it may be that the Px

has an out of date version of software. A few Allworx Px 6/2 Expanders

with the earliest version of pre-loaded software do not properly utilize the

DHCP Option 66 information. If your Px is one of these units, it must be

manually upgraded by either (A) temporarily connecting it to an Allworx

server that is not connected to the site's network or (B) manually

configuring the Px's network settings. The procedures work equally well so

choose the one that is more convenient for the situation:

A. Temporary offline connection – In this procedure, you will connect

the Px to an Allworx server that is not connected to the site's network. Any

Allworx 6x, 10x, or 24x server can be used. However, you must choose a

server on which the DHCP server is enabled. The server will upgrade the

Px to the latest version of software. Once upgraded, the Px will be able to

use the DHCP Option 66 information and properly plug and play on the

site's network. Perform the following steps: • Upgrade the Allworx server to System Software Release 6.9.2.1 or higher. • Ensure that the server's DHCP server is enabled. This setting is found on the Allworx server admin page under Servers > DHCP. Note that if the Allworx server is on a network that already has a separate DHCP server, the Allworx server must be disconnected from the network before you enable DHCP on the Allworx server. • If the Px has already been powered on, disconnect power.

• Verify that the PC has an IP address on the 192.168.2.xxx network by typing ipconfig /all in a command window on the PC. If the PC did not receive the address, it may be necessary to release and renew the PC's IP address using the ipconfig command in a command window. • Open a web browser on the PC and enter http://192.168.2.254 into the browser's address field. The Px's Configuration screen is displayed. • Navigate to the Boot Server IP Address field.

3 Allworx Px units must have an Allworx Internet Call Access (or VoIP) key for the Px units to work. If your Allworx system already has an Internet Call Access Key, a second key is not necessary and you are all set for full functionality of the Px unit(s). If your system does not have the VoIP key, Allworx will supply the key via a request form on the Allworx Partner Portal. Note: The serial numbers of the Allworx server and the Px unit are both required to request your key.

it reboots while connected to the server. -Where can I get the latest installation instructions for the Allworx Px 6/2 Expander? A copy of the guide is packaged with each Px. The latest version of the guide can be downloaded from the Allworx Partner Portal, under Support & Training > Documentation. Setup of the Px's FXO and FXS ports is done through the Allworx server admin page. Instructions are found in the Allworx Server Administrator's Guide (6.9.2.

CAUTION: If the network connection between the Px and the Allworx server is interrupted, regular use of the Px's FXO and FXS ports will not be possible. The only option for placing calls through a Px 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 the LAN Host Mode FAQ. If the site requires that the Px have a static IP address, refer to the Static IP Address FAQ. -How do I configure the Allworx Px 6/2 Expander for LAN Host Mode? If the Allworx server is in LAN Host mode and it is NOT the site's DHCP server, Px network configuration changes may have to be made. However, if the site's DHCP server supports Option #66, the changes are limited to the DHCP server side.

LED is flashing). Immediately unplug the service PC's cable from the Px and connect the Px to the customer's network. When the Px is in Normal Mode, the Power LED will light green and the Port LEDs will be dark. If this does not happen, unplug and re-plug the Px's power supply. -How do I give the Allworx Px 6/2 Expander a static IP address? First, put the Px in Configuration Mode: Remove the power and Ethernet cables from the Px unit. Plug the power back into the Px unit.

Remote connection of Port Expanders is supported. However, the following very important cautions must be taken into account: 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. 911 calls placed from a handset connected to an Allworx Px will be routed using the service rule on the Allworx server.

typing cmd into the Open field and then clicking OK. On the command line in the window, type: ipconfig /release and press the Enter key. Once the command prompt is re-displayed, type: ipconfig /renew and press the Enter key. Once the command prompt is re-displayed, enter the Px's IP address (192.168.2.254) into the address field of the PC's web browser and click Go. Change the Px's network settings: Into the Boot Server IP Address field, enter the Allworx server's LAN IP address.

Once the command prompt is re-displayed, enter the Px's IP address (192.168.2.254) into the address field of the PC's web browser and click Go. When done, disconnect the PC's Ethernet cable, plug the regular network cable back in, and power cycle the unit. -How do I access the Allworx Px 6/2 Expander’s network settings? In Normal Mode, the settings can be accessed through the Allworx server's administration web page. Log into the server and go to Network > Port Expanders.

If the Px is directly connected to the Internet or has a Public IP mapped to it, you will be able to access it from a web browser using its public IP address. Accessing troubleshooting tools or changing its network settings requires that you enter the Px's password. If the password has not been set or if it has been forgotten, the password will have to be set or changed while physically at the same site as the Px.
