Chapter 4. Device Management via User Interfaces
4.2.7 Trivial File Transfer Protocol (TFTP)
The CMR-8500 supports changes to the resident software and firmware by means of the Trivial File
Transfer Protocol (TFTP). This enables changes to be made remotely via the LAN interface. It is
recommended to use Solarwinds TFTP server application (available at
http://support.solarwinds.net/updates/SelectProgramFree.cfm ).
To modify the software and/or firmware, use the following procedures:
Configure the server as follows:
a) File Æ Configuration Æ Select the ‘ TFTP Root Directory ’. Set up the location of the
CMR-8500 files.
b) File Æ Configuration Æ Select the ‘ Security ’ tab and make sure ‘ Transmit and Receive ’
are selected.
c) Save configuration.
The server is now configured for the file transfer process.
Because the CMR-8500 requires a reboot during the upgrade process, it is
recommended that this upgrade procedure be performed during scheduled
network down time.
Do NOT remove power from the unit during the download process.
