5.0 Upgrading Firmware
5.1 Upgrading DM3X 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 in 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 DM3X requires its own firmware and manufacturer’s Code Verification Certificate (CVC
file).
Contact Alpha Technologies Services, Inc. to obtain the latest firmware and manufacturer’s CVC files.

IP Address
The IP address of the TFTP server from which the firmware
will be downloaded. This OID has been deprecated, refer to
docsDevSwServerAddress (OID:1.3.6.1.2.1.69.1.3.7.0).
docDevSwFilename
OID: 1.3.6.1.2.1.69.1.3.2.0
Octet String Set to the filename of the firmware file. Example:
[“firmwareImage.bin”]

Integer
1 = Initiate upgrade (manual method)
2 = Upgrade on next reboot (Config File Method)
3 = Ignore update
docsDevSwOperStatus
OID: 1.3.6.1.2.1.69.1.3.4.0
Integer,
Read Only
1 = TFTP download is in progress
2 = Last upgrade was performed at reboot
3 = Last upgrade was initiated by setting
docsDevSwAdminStatus to “1”

IP Address
The IP address of the server from which the firmware will be
downloaded. A set of this object to an IPv4 address will result
in also setting the value of docsDevSwServer to that address.
If this object is set to an IPv6 address, docsDevSwServer is set
to 0.0.0.0. If docsDevSwServer is set, this object is also set to
that value.
