DSM16 - Identifying its IP Address

Both the DSM16 card and module are configured by default to use DHCP procedures to obtain an IP address on initial connection. This is because it is likely that more than one DSM16 will be deployed in most scenarios and cannot all be assigned a common default IP address. Therefore, it is a prerequisite that the initial DSM16 network connection is made to a network that has a DHCP server. Once it is connected to the network, the address for connecting to the DSM16 Web-based Configuration Utility will be dependent on the address provided by the network's DHCP Server. 

Identifying the IP Address

There are a number of installation scenarios to consider for identifying and initial configuring of the DSM16 IP Address.

Identifying the IP Addresses through a Digital Set Display

Because the default setting for the DSM16 is to operate in Norstar/BCM mode, this step can only be performed with a Norstar or BCM set. If you are configuring for a CS1000 or M1 replacement, or if you have Avaya 95xx phones, consider bringing a Norstar/BCM phone for this initial step, or use one of the other methods identified below.

One of the simplest methods for determining the DSM16 IP address after it is connected to a network is to connect any Norstar/BCM digital set with a two line display to one of the ports on the RJ-21 jack output.  During the DSM16 initialization process, the display of the set will be blank and all the Key Indicators will be blinking.  However, once the initialization has finalized, the Key Indicators will stop blinking, and if the DSM16 does not automatically connect to the UCX server, the two line display will begin alternating between three messages.  The first message will have a "DSM16 IP address" and the second line will have the currently assigned IP address of the DSM16.  The message will then transition to "Locating Server" on the first line, with the IP address of the UCX server on the second line.  The third message provides feedback indicating "Server not found", again followed by the UCX server IP address.



In the example discussed below, the display would alternate between the following screens:

  DSM16 IP address

192.168.1.202
  Locating Server

192.168.1.200
  Server not found

192.168.1.200

Direct Connection with Galaxy system with Server

If you are connecting the DSM16 directly to one of the Galaxy network interfaces, then consider using the DHCP server capabilities of the UCX software. (Make sure there are no other DHCP servers on the same network first!) After enabling DHCP on the network interface per the DHCP Server documentation, you can review the DHCP Client List to determine the IP address assigned to the DSM16 module or card by matching its' MAC address in the client list.

Network with no DHCP Server

If there is a requirement to place the DSM16 on a network that does not have a DHCP server (i.e. remote from the Galaxy server interfaces), then the initial configuration must be done on a separate network (or possibly directly connected to a PC with a DHCP server) with the last step being to change the network interface parameters for the target network.

Pre-Assigning the MAC address on the DHCP Server

The address can be pre-assigned by using the Hardware ID (MAC Address) provided on the product label and having the DHCP Server administrator create an IP address reservation for the unit.  This will allow the DSM16 to connect to the network with the normal DHCP procedures and receive the pre-assigned address from the server.
