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 DSM 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

(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 conguration 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.

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 RF MAC Address

and the MAC Address needs to be assigned a DOCSIS Conguration File.

The DOCSIS Conguration 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

settings in SNMP MIB tables. SCTE-HMS and Alpha MIBs must be installed in the browser. Alarms and traps can be set and monitored.

The power supply and generator may be accessed remotely through the Communications Module's Web page by placing its

IP address into a standard Internet Web browser.

10 745-814-B8-001, 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:

• MAC ltering may have to be modied to allow RF MAC registration of addresses starting with

• 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.

00:90:EA - North American or 00:03:08 - Euro 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 Conguration and Installation

NOTE:

Before installation, read all of the “System Overview” sections.

DSM3 Series installation and setup is comprised of three basic steps:

1. Conguring the Network: Provisioning the DHCP Server with the Communications Module’s MAC Address and assigning it a DOCSIS Conguration 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 Conguration File per RFC 4639, 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 sense wire harnesses and verifying operation.

These steps can be performed independently of one another. However, conguring the network prior to eld installation will allow the installation to be veried while personnel are still on-site. Performing eld installation before network conguration and before the installation can be veried, 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 conguration or hardware installation.

3.0 Network Conguration

3.1 Provisioning the DHCP Server with the MAC addresses

On the DHCP server, assign the cable modem’s RF MAC address with a DOCSIS Conguration File

to set modem communication options. (See Section 3.3 for instructions on how to create a DOCSIS

Conguration File).

The RF and CPE MAC addresses are located in two places on the DSM3 Series and on the packing slip, see below.

3.2 Establishing IP Connectivity

The DSM3 Series supports the CableLabs DOCSIS 2.0+IPv6 implementation. The main benet 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 congurable 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 Conguration File

A cable modem’s DOCSIS Conguration File is a type-length-value (TLV) le that contains important operational parameters as dened by the DOCSIS standards. It provides certain settings for the cable modem. In addition to standard entries, settings in the DOCSIS Conguration File should include the modem’s community strings and if an upgrade is necessary, rmware upgrade parameters. Place the Conguration File in the TFTP root directory.

The DSM3 Series cable modem interface can support both IPv4 and IPv6 addressing schemes. The

required DOCSIS Conguration File operational parameters will differ depending on company policies, cable modem rmware versions and IP addressing schemes. The following DOCSIS Conguration File details listed in this manual are general guidelines. Please consult the published DOCSIS Specication resources (CableLabs) for additional DOCSIS Conguration File details and guidelines.

To build a DOCSIS Conguration File, use a DOCSIS TLV editor program. See the example Conguration Files in Sections 3.3.5 and 3.3.6.

NOTE:

The modem community strings should be set in the DOCSIS Conguration File. Failure to set community strings will result in a less secure system. For automatically updating modem rmware with the DOCSIS Conguration File, see Section 5.1, Upgrading DSM3 Series Modem Firmware.

In previous versions of the DSM product line, an additional conguration 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.

3.3.7 Proprietary Conguration File ‘atidoc03.cfg’

The DSM3 Series will attempt to download a TLV-formatted le ‘atidoc03.cfg’ from the modem’s

provisioning TFTP server at startup and every 24 hours thereafter. The atidoc03.cfg proprietary

conguration le is optional and provides an alternative method to the modem’s DOCSIS conguration 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 conguration le.

NOTE:

The recommended method for setting the SNMP trap address(es) is through the modem DOCSIS conguration le (See Section 3.3, The DOCSIS Conguration File). Alpha-proprietary parameters may also be set through the modem’s DOCSIS conguration le, eliminating the need for the atidoc03.cfg proprietary conguration 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 below for sample atidoc03.cfg entries. The DSM3 Series proprietary conguration Setup le must be named “atidoc03.cfg” and placed in the root directory of the TFTP server. DSM3 settings are updated according to values dened in this le at

startup and after every 24 hours of operation.

Sample atidoc03.cfg Entries:

SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.1 / 10.20.30.40 SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.2 / 10.20.30.50 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

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 congure 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/congure 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
