Understanding the Difference Between 'Apply' and 'Save'
Understanding the Difference Between 'Apply' and 'Save'
The graphical user interface for DMPDM contains elements that help you to activate any change that you
make, and it is important that you understand the difference between activating a change temporarily or
doing so permanently.

Understanding Content Substitution (Failover)
If an HTTP status code of 404 or 500 prevents your DMP from obtaining the content that you scheduled
it to show, your DMP has two stages for failover. In stage-one failover, your DMP shows Zoning
Application content files that you uploaded to the SD memory card, assuming that the cumulative filesize
is no greater than 900 MB. See the "Working with Screen Zones" topic in Chapter 3 of User Guide for
Cisco Digital Media Manager 4.0 on Cisco.com.
If your DMP is not able to play the Zoning Application content files that you saved to the SD card, or if
no such content files are on the SD card, your DMP enters stage-two failover and starts to play content
that is stored in ROM. The content in ROM is video that shows a butterfly, and your DMP plays the video
repeatedly in a loop that persists until one of the following occurs:

The video clip in ROM has no other purpose than stage-two failover. You cannot change the stage-two
failover content and you cannot delete it.
Preconfiguring Your DMP To Run Without a Local DHCP Server
The factory default for every DMP is to obtain and use a dynamic IP address from a DHCP server at the
deployment site. However, your DMP must have an assigned IP address even if you will use it at a site
where there is no local DHCP server. In that case, you must preconfigure your DMP to use a static IP
address before you can deploy it.
Use a composite video cable (yellow, red, white) to connect your DMP to a display.
Step 1
Turn on the display, then do one of the following:

To confirm that you are satisfied with changes that you made to the values for a condition or setting,
click Apply. After you click Apply, the changes take effect. However, the changes are temporary
and the previously defined values for the pertinent condition or setting will return as soon as the next
time that your DMP restarts.
To put all changed values into effect permanently, so that they persist even after your DMP restarts,
select Administration > Save Configuration. When the Save Configuration page appears, you
must click Save.
Your DMP obtains the content that it is scheduled to play.
You use the "Stop All Applications" feature in DMM-DSM. See the "Using Other DMM-DSM
Applications" topic in Chapter 3 of User Guide for Cisco Digital Media Manager 4.0.
You restart or shut down your DMP.
Use a standard, category 5 (10/100) Ethernet cable to connect your DMP to a network segment that
includes a DHCP server.
Use an Ethernet crossover cable to connect your DMP directly to a DHCP server (and, if the DHCP
server process is not running, start it now).
