5.0 Upgrading Firmware
5.1 Upgrading XP-DSM Modem Firmware
The rmware in the XP-DSM’s modem is upgraded using standard DOCSIS methods as
dened in RFC2669 (available at http://www.faqs.org/rfcs/rfc2669.html).
There are two ways to upgrade the modem’s rmware: 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 Conguration File, stored on the TFTP root
directory.
Both methods are explained below. To build a DOCSIS Conguration 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 rmware and manufacturer’s Code Verication Certicate (CVC) les. These
versions can be differentiated by the rst three hexadecimal pairs, known as the
Organizationally Unique Identier (OUI), in their MAC Addresses:
00:03:08 AM
00:05:CA Hitron
The rmware and CVC les 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 rmware and CVC les for your modem
version.
