Appendix A. SOFTWARE UPGRADE
A.1 Introduction
The CMR-8500 supports changes to the resident software and firmware by two methods:
• Trivial File Transfer Protocol (TFTP)
• File Transfer Protocol (FTP)
Using TFTP, the transfer is initiated from the CMR-8500 using the unit’s web interface, and connecting
to a remote TFTP server. If FTP is to be used, the transfer is initiated remotely and an FTP session is
created between the CMR-8500 and the remote device (typically a PC).
The CMR-8500 supports two banks of firmware. The user has the capability to select which bank of
firmware to boot from, as well as which bank to update.
A.2 Software Upgrade via TFTP, Using the CMR-8500 Web Interface
If TFTP is to be used for software upgrades, 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.
