5.0 Upgrading Firmware
5.1 Upgrading XP-DSM Modem Firmware
The firmware in the XP-DSM’s modem is upgraded using standard DOCSIS methods as
defined in RFC2669 (available at http://www.faqs.org/rfcs/rfc2669.html ).
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. To build a DOCSIS Configuration File, see
Section 3.2 .
5.1.1 Identifying the Modem and Obtaining Firmware Files
There are two versions of the cable modem in XP-DSMs, each of which requires its
own firmware and manufacturer’s Code Verification Certificate (CVC) files. These
versions can be differentiated by the first three hexadecimal pairs, known as the
Organizationally Unique Identifier (OUI), in their MAC Addresses:
00:03:08 AM
00:05:CA Hitron
The firmware and CVC files for each modem can be downloaded from the XP-DSM
website: www.Alpha.com>Broadband Cable>Status Monitoring>DSM>XP-DSM Tech.
Support . Take care to download the correct firmware and CVC files for your modem
version.
