Download via HTTP/HTTPS
The following steps explain how to download a software by using the HTTP protocol.

or HTTPS If you are using HTTPS, the Mediatrix 4104 must contain the proper certificate. See “Configuring
the HTTPS Server” on page 206 for more details. To download a software via HTTP or HTTPS:
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 http or https .
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 your HTTP or HTTPS server requires authentication, set the following:
• The user name in the imageTransferUsername variable.
• The password in the imageTransferPassword variable.
6. Set the groupSetAdmin variable (in the groupAdminMIB ) to ForceLock .
All activities in progress on the Mediatrix 4104 are terminated immediately and the unit enters the
maintenance mode (the value of the
groupAdminState variable is “locked”). The software upgrade
may take place.
The Mediatrix 4104 lines will be unlocked after successfully downloading the software and
restarting.
If, for any reason, the software download is not successful, you must manually unlock the lines as
per
“Lines Administrative State” on page 221 .
7. Initiate the download by setting the sysAdminCommand variable (in the sysAdminMIB ) to
downloadSoftware .
This starts the download process.
The software download may take several minutes, depending on your Internet connection, network
conditions and servers conditions.
8. Update the MIB browser with the MIB version coming with the software version.
User Agent Header of HTTP Requests
The User-Agent header field of an HTTP request contains information about the user agent client originating
the request. For instance, the information of the User-Agent header could be something like the following:
User-Agent: Softphone Beta1.5
You can customize the information that the Mediatrix 4104 sends when establishing a communication.
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.
Caution:
Never shutdown the Mediatrix 4104 manually while in the download process, because the image
may be partially written and the Mediatrix 4104 is unable to restart.
