Upgrade Procedure Summary

There are six basic steps to perform an upgrade to a CM 100 using a
standard SNMP manager.
1. Verify contents of upgrade package.
2. Configure TFTP file server.
3. Initiate upgrade process.
4. Upgrade and compile the latest cable modem SNMP MIB.
5. Verify upgrade completed successfully.
Note: If unit fails to respond after upgrade procedure, remove the unit from
the cable system before performing any troubleshooting procedures,
especially resetting the unit to factory defaults.

Step #1: Verify Contents of Upgrade Package

The distribution method for the CM 100 upgrade is via a Nortel
Network-maintained FTP server and web site. Upgrade software directories
will include separate software files for the CM 100 and the CMTS 1000.
All pertinent SNMP MIB files are also included.

Step #2: Configure TFTP File Server

Perform the following procedure to setup the TFTP file server and install
the upgrade software.
Set the TFTP server's default or public directory to the directory where you
will be copying the upgrade software.
Copy the CM 100 and CMTS 1000 upgrade software files to the TFTP
server's default directory. We recommend using the data directory that you
use to save and provision the cable modem's configuration and MD5 files.
