4.5 T rivial File Transfer Protocol (TFTP)
The MR-S2 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 MR-S2 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.
IMPORTANT
Because the MR-S2 stops processing data traffic during the
download 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.
