Download via HTTP
The following steps explain how to download a software by using the HTTP protocol.
 To download a software via HTTP:
1. If not already done, setup the Image server used to download the software (see “
Before
Downloading” on page 115).
2. If not already done, configure the Image path as described in “
Setting up the Image Path” on
page 118.
3. If not already done, configure the image hosts and ports as defined in “
Software Servers
Configuration” on page 116.
4. In the imageMIB, set the imageTransferProtocol variable to http.
Your HTTP 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 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 4100 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 4100 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 129.
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.
Caution: When downloading via HTTP, 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 116 for more details.
Caution: Never shutdown the Mediatrix 4100 manually while in the download process, because the image
may be partially written and the Mediatrix 4100 is unable to restart.
