216 Mediatrix 4104
Automatic Update at a Specific Time Interval
You can configure the Mediatrix 4104 to download a software version at a specific day and/or time.

To set the automatic update at a specific time interval:
1. If not already done, setup the Image server used to download the software (see “Before
Downloading” on page 205 ).
2. If not already done, configure the Image path as described in “Setting up the Image Path” on
page 209 .
3. If not already done, configure the image hosts and ports as defined in “Software Servers
Configuration” on page 207 .
4. In the imageMIB , set the imageTransferProtocol variable to either http , https , or tftp .
If you are using the HTTPS protocol, the Mediatrix 4104 must contain the proper certificate. See
“Configuring the HTTPS Server” on page 206 for more details.
If you are using the HTTP or HTTPS protocol to download the software, be aware that your HTTP
or HTTPS server may activate some caching mechanism for the software download. This
mechanism caches the initial software download for later processing, thus preventing changes or
update of the original download by the user. This can cause problems if a user wants to modify the
software download and perform it again immediately. The result will still return the original download
and not the new one.
5. If you are using the HTTP or HTTPS protocol and your HTTP or HTTPS server requires
authentication, set the following:
• The user name in the imageTransferUsername variable.
• The password in the imageTransferPassword variable.
6. Define the time base for automatic software updates in the imageAutoUpdateTimeUnit variable (in
the imageAutomaticUpdate group).
You have the following choices:
Caution:
When downloading via HTTP or HTTPS, the image server’s port must be 80. You can query the
actual port assigned in the imagePrimaryPort and imageSecondaryPort read-only variables (in the
ipAddressStatus folder).
If you are using a DHCP server and it did not provide the proper port, reconfigure it with the proper port or
use a static configuration. See
“Software Servers Configuration” on page 207 for more details.
