1.0 Introduction
The AlphaNet DSM3 Series Embedded DOCSIS Communications Module allows monitoring of Alpha power
supplies through existing cable network infrastructure. Advanced networking services provide quick reporting
and access to critical powering information. This manual focuses on the three models of the DSM3 Series
Communications Module complementing the XM3-HP CableUPS.
The DSM3 Series Communications Modules utilize Simple Network Management Protocol (SNMP) and
Management Information Bases (MIBs) to provide network status monitoring and diagnostics. A Web interface
enables authorized personnel direct access to advanced diagnostics using a common Web browser. No custom
software is required. See Table 1-1 for model specications.

All power supply data is stored in the power supply Inverter Module's class information base (CIB) tables in the power supply.

This data is accessible directly via the power supply’s Smart Display (see the power supply’s technical manual for details).
The CIB tables are the source of the Communications Module's data.
The DSM3 Series contains both SCTE-HMS Management Information Base (MIBs) and the proprietary Alpha MIB tables.
The SCTE-HMS MIBs are industry standard MIB tables that store power supply, battery and generator data from the CIB
tables (DSM3x only) (See Section 6.0, Data Management). The Alpha MIB contains all the data of the SCTE-HMS MIBs
plus additional power supply settings and values as well as DSM3 Series conguration values.
An external generator or additional power supplies may be connected through the COM (AlphaBus) port permitting
monitoring locally through the Ethernet connector or remotely via the Web page or SNMP-based Network Management
System (DSM3x only).

Power supply and Communications Module parameters can be monitored and set locally using a personal computer and a
standard Ethernet cable.
The DSM3 Series transmits data via its cable modem directly over the Coax or Hybrid Fiber Coax network.
The Cable Modem Termination System (CMTS) is the bridge between the cable network and the TCP/IP network. The DSM3
Series’ cable modem communicates directly with the CMTS.
The Dynamic Host Control Protocol (DHCP) server needs to be provisioned with the DSM3’s cable modem CM MAC
address and the MAC address needs to be assigned a DOCSIS Conguration File.
The DOCSIS Conguration File and rmware les should be available in the Root Directory of the Trivial File Transfer
Protocol (TFTP) Server.
The Time of Day (TOD) Server provides the cable modem with the current date and time via the SNTP protocol.
A Network Management System (NMS) or MIB Browser allows remote monitoring of parameter values and changing of
10
settings in SNMP MIB tables. SCTE-HMS and Alpha MIBs must be installed in the browser. Alarms and traps can be set and
monitored.
11
12
The power supply and generator data may be accessed remotely through the Communications Module's Web page by
placing its IP address into a standard Internet Web browser.
The following ports of the Transmission Control Protocol/Internet Protocol network must be opened: 161=SNMP, 162=SNMP,
Traps, 69=TFTP, 80=HTTP.
10
745-814-B11-001, Rev. C (03/2014)
2.0 Overview
2.2 Network Connectivity
The DSM3 Series cable modem must be recognized by the CMTS as a valid device to be assigned an IP
address from the DHCP server, to locate the TFTP and TOD servers and to communicate with the SNMP
management server (trap receiver).
Data from both the cable modem and power supply are accessed and managed through the modem’s IP
address on the secure private modem network. The Communications Module is not accessible from the
public Customer Premises Equipment (CPE) network. Consequently, the Network Management System
(NMS) that monitors the power supplies must have access to the same private modem network.
CMTS and system vendors use different security methods to insure network integrity, but common
considerations are:
• Network MAC ltering may have to be modied to allow the cable modem OUI of 00:90:EA for North
• For SNMP access, UDP ports 161 and 162 must not be blocked.
• For TFTP access, port 69 must not be blocked.
• For HTTP access, port 80 must not be blocked.
• For SNTP access, port 37 must not be blocked.
America, and 00:03:08 for European models.
• Firewalls must allow TFTP, DHCP, SNMP and TOD communication to the cable modem.
• If the address of the TFTP or TOD server is different than the DHCP server, the response from the
DHCP server must contain the TFTP and TOD addresses.
2.3 System Conguration and Installation
NOTE:
Before installation, read all of Section 2.0, Overview.
DSM3 Series installation and setup is comprised of three basic steps:
1. Conguring the Network: Provisioning the DHCP Server with the Communications Module’s MAC
address and assigning it a DOCSIS Conguration File.
2. Setting Options: The DSM3 Series is designed for out of the box, "plug and play" operation, but
non-default settings such as SNMP trap destination addresses may be required for the Network
Management System (NMS). SNMP trap addresses can be set automatically via the DOCSIS
Conguration File per RFC 4639 (IPv4), or through SNMPv3 Notication settings (IPv6), while DSM3
Series proprietary options may be set through type-11 TLV entries. The SCTE-HMS and Alpha MIBs
may need to be compiled into a MIB browser before it can be used to monitor or set Communications
Module and power supply parameters.
3. Field Installation of the DSM3 Series into the power supply, connecting the battery string wire
harnesses, Tamper, and Environmental Control (as applicable) and verifying operation.
These steps can be performed independently of one another. However, conguring the network prior
to eld installation will allow the installation to be veried while personnel are still on-site. Performing
eld installation before network conguration and before the installation can be veried, might result in
additional eld service calls to correct mistakes.
Carefully read the following section in order to understand the dependencies within the system before
performing system conguration or hardware installation.

3.0 Network Conguration
3.1 Provisioning the DHCP Server with the MAC Addresses
On the DHCP server, assign the cable modem’s CM MAC address with a DOCSIS Conguration File to
set modem communication options. (See Section 3.3, The DOCSIS Conguration File for instructions
on how to create a DOCSIS Conguration File).
The CM and CPE MAC addresses are located in two places on the DSM3 Series and on the packing slip,
see below. The CM MAC address may be labeled as the RF MAC address on some DSM3 Series units.

3.0 Network Conguration
3.2 Establishing IP Connectivity
The DSM3 Series supports the CableLabs DOCSIS 2.0+IPv6 implementation. The main benet of
IPv6 is its expanded addressing capability, increasing the address space from 32 to 128 bits, providing
virtually unlimited number of networks and systems. The DSM3 Series determines the IP provisioning
mode via the CableLabs SNMP MIB parameter docsIf3CmMdCfgIpProvMode (SNMP OID: 1.3.6.1.4.1
.4491.2.1.20.1.31.1.1). The DSM3 Series will support the following congurable IP Provisioning Mode
Override policies:
• Honor MDD: The cable modem of the DSM3 Series unit will acquire an IPv6 or IPv4 address as
directed by the MAC Domain Descriptor (MDD) message for provisioning and operation.
• IPv4 only: The cable modem of the DSM3 Series unit will acquire a single IPv4 address for the CM
management stack, overriding the TLVs in the MDD message.
• IPv6 only: The cable modem of the DSM3 Series unit will acquire a single IPv6 address for the CM
management stack, overriding the TLVs in the MDD message.
3.3 The DOCSIS Conguration File
A cable modem’s DOCSIS Conguration File is a type-length-value (TLV) le that contains important
operational parameters as dened by the DOCSIS standards. It provides certain settings for the cable
modem. In addition to standard entries, settings in the DOCSIS Conguration File should include the
modem’s community strings and if an upgrade is necessary, rmware upgrade parameters. Place the
Conguration File in the TFTP root directory.
The DSM3 Series cable modem interface can support both IPv4 and IPv6 addressing schemes. The
required DOCSIS Conguration File operational parameters will differ depending on company policies,
cable modem rmware versions and IP addressing schemes. The following DOCSIS Conguration File
details listed in this manual are general guidelines. Please consult the published DOCSIS Specication
resources (CableLabs) for additional DOCSIS Conguration File details and guidelines.
To build a DOCSIS Conguration File, use a DOCSIS TLV editor program.
See the example Conguration Files in Sections 3.3.5 and 3.3.6.
NOTE:
The modem community strings should be set in the DOCSIS Conguration File. Failure to set community strings
will result in a less secure system. For automatically updating modem rmware with the DOCSIS Conguration File,
see Section 5.1, Upgrading DSM3 Series Modem Firmware.
3.3.1 Setting Modem Community Strings — DOCSIS 2.0 (IPv4) Method
Set the modem community strings with the DOCSIS Conguration File by including the following
SNMP parameters:

In previous versions of the DSM product line, an additional conguration le (also known as a Setup File)
could be used for distributing custom Alpha MIB settings to all DSMs on a network. This is still the case,
with the only difference being the name of the le, which for the DSM3 Series is atidoc03.cfg. It may be
used if preferred, but is not required.

3.0 Network Conguration
3.3 The DOCSIS Conguration File
3.3.7 Proprietary Conguration File ‘atidoc03.cfg’
The DSM3 Series will attempt to download a TLV-formatted le ‘atidoc03.cfg’ from the modem’s
provisioning TFTP server at start up and every 24 hours thereafter. The atidoc03.cfg proprietary
conguration le is optional and provides an alternative method to the modem’s DOCSIS
conguration le for deploying Alpha proprietary SNMP MIB parameters to eld-installed DSM3 Series
Communications Modules.
The atidoc03.cfg le should be used if the following conditions are true:
1. Non-default settings, such as SNMP Trap Destination Addresses need to be distributed to all
DSM3 Series Communications Modules.
2. The operator does not desire to place Alpha-proprietary parameters into the modem’s DOCSIS
conguration le.
NOTE:
The recommended method for setting the SNMP trap address(es) is through the modem DOCSIS conguration le
(See Section 3.3, The DOCSIS Conguration File). Alpha-proprietary parameters may also be set through the
modem’s DOCSIS conguration le, eliminating the need for the atidoc03.cfg proprietary conguration le.
To build the atidoc03.cfg le, enter the desired SNMP OIDs and values from the Alpha MIB into a
TLV le as TLV type-11 entries using a TLV editor (Refer to sample entries below). The DSM3 Series
proprietary conguration Setup le must be named “atidoc03.cfg” and placed in the root directory of
the TFTP server. DSM3 settings are updated according to values dened in this le at start up and
after every 24 hours of operation.
Sample atidoc03.cfg Entries:
Network Access Control (3) [Len - 1]: 1
SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.1 / 10.20.30.40

SNMP MIB Object (11) [Len = 23]: atiMgmtSysTamperPolarity.0 / 1
3.3.8 Changing Default atidoc03.cfg Download Settings
By default the DSM3 Series will download the atidoc03.cfg le from the provisioning TFTP server
every 24 hours. However, these settings may be adjusted per the tables below by placing the
respective SNMP varbinds into the modem’s DOCSIS conguration le.

4.0 Web Interface
Overview
The DSM3 Series Communications Module provides an embedded Web server interface to allow operations
personnel the ability to connect locally or remotely via TCP/IP over Ethernet with a laptop/computer to verify the
status of common data points and to congure various operating parameters.
4.1 Local Web Server Access
The DSM3 Series Communications Module’s Ethernet port (comparable to the Craft port on some
Communications Module models) will typically be used as a local connection point allowing the user to
connect directly to the DSM3 Series Web server interface to verify/congure common communication
parameters and view power supply status and battery values. The Ethernet port on the DSM3 Series is a
fully functional standard Ethernet port, capable of providing all the functionality of any standard Ethernet
connection.
To access the DSM3 Series Communications Module Web server locally utilizing a Web browser, use the
following procedure:
NOTE:
The following Web Browser settings should be
‘enabled’ for proper rendering/download of the
web pages:
• Java Script
• Cookies
• ActiveX Controls
