Download via TFTP
The following steps explain how to download a software by using the TFTP protocol.
 To download a software via TFTP:
1. If not already done, setup the Image server used to download the software (see “
Before
Downloading” on page 115).
2. Be sure that UDP ports 60000 to 60512 inclusively are opened in your firewall.
3. If not already done, configure the Image path as described in “
Setting up the Image Path” on
page 118.
4. If not already done, configure the image hosts and ports as defined in “
Software Servers
Configuration” on page 116.
5. Set the TFTP root path in your TFTP server.
It is assumed that you know how to set the TFTP root path. If not, refer to your TFTP server’s
documentation.
6. Set the imageTransferProtocol variable to tftp.
7. 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.
8. 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.
9. Update the MIB browser with the MIB version coming with the software version.
In the Unit Manager Network Administration Manual, refer to chapter Performing Actions on Mediatrix Units,
section Downloading a Software Version.
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.
