Cisco Cisco Professional Series 42-inch LCD Release Notes

If you enter only an IP address during set up, the Cisco DMS appliances cannot communicate with each 
other. Cisco DMS appliances will not work correctly without a DNS server. Please enter a fully-qualified 
domain name (FQDN).

To maintain network security, your DMM appliances and Video Portal appliances use digital 
certificates to communicate. These certificates use the DNS-routable hostname to identify each 
appliance uniquely. Therefore, you must enter the DNS-routable hostname for each appliance during 
setup when prompted to enter the fully-qualified domain name (FQDN) in AAI. 

You must also configure each of your DMS appliances in AAI to point correctly to the DNS server 
for your network and configure that DNS server to associate the IP addresses that your DMS 
appliances use with the FQDNs that their digital certificates use. 

When setting up your DMS 5.1.x appliances, do not use “Cisco” as the instance name for your Video 
Portal appliance. We reserve the use of the Cisco name for other purposes, and all deployments will 
fail if you use this instance name.

You can upgrade from Cisco Digital Media System 5.0.x to 5.1.x. For more information, including 
requirements and procedures, see Upgrade Guide to Release 5.1.x for Cisco Digital Media System on 
Cisco.com.
