Software Servers Configuration
The Mediatrix 1204 must know the IP address and port number of its Primary and Secondary software servers.
These servers contain the files required for the software update. You can assign these information to the
Mediatrix 1204 through a DHCP server or manually enter them yourself in static variables.
DHCP Configuration
Using the DHCP configuration assumes that you have properly set your DHCP server with the relevant
information. See
“Chapter 8 - IP Address and Network Configuration” on page 117 for more details.

To use DHCP-assigned information:
1. In the ipAddressConfig folder, locate the imageSelectConfigSource variable (under the
ipAddressConfigImage group).
This variable defines whether the Mediatrix 1204 must ask for its Image server settings through a
DHCP server or not.
2. Set the imageSelectConfigSource variable to dhcp .
You can query the Image server’s IP address and port number assigned by the DHCP server in the
following read-only variables (in the
ipAddressStatus folder):
• imagePrimaryHost
• imagePrimaryPort
• imageSecondaryHost
• imageSecondaryPort
3. Set how you want to define the Primary Image server information in the DHCP server.
See “Vendor and Site Specific DHCP Options” on page 130 for more details.
