5.1 Upgrading DSM3 Series Modem Firmware
The firmware is upgraded using standard DOCSIS methods as defined in RFC4639.
There are two ways to upgrade the modem’s firmware: by directly setting the appropriate MIB parameters
in the docsDevSoftware branch, or by including the appropriate SNMP parameters and values in the
modem’s DOCSIS Configuration File, stored on the TFTP root directory.
Both methods are explained below.
5.1.1 Identifying the Modem and Obtaining Firmware Files
The cable modem firmware in the DSM3 Series requires its own firmware and manufacturer's
Code Verification Certificate (CVC file).
Contact Alpha Technologies to obtain the latest firmware and manufacturer's CVC files.
