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).
1
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
2
(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
3
System.
Power supply and Communications Module parameters can be monitored and set locally using a personal computer and a
4
standard Ethernet cable.
The DSM3 Series transmits data via its cable modem directly over the Coax or Hybrid Fiber Coax network.
5
The Cable Modem Termination System (CMTS) is the bridge between the cable network and the TCP/IP network. The DSM3
6
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
7
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
8
Protocol (TFTP) Server.
The Time of Day (TOD) Server provides the cable modem with the current date and time via the SNTP protocol.
9
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.
The power supply and generator may be accessed remotely through the Communications Module's Web page by placing its
11
IP address into a standard Internet Web browser.

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 modied 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 Conguration and Installation
NOTE:
Before installation, read all of the “System Overview” sections.
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, 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, 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 RF MAC address with a DOCSIS Conguration File
to set modem communication options. (See Section 3.3 for instructions on how to create a DOCSIS
Conguration 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 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.

3.0 Network Conguration, continued
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:

DOCSIS conguration les vary from system to system. Take into consideration your company's policies, and
test the le on a local system prior to widescale deployment.
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
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
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 below for sample atidoc03.cfg entries. 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
By default the DSM3 Series will download the atidoc03.cfg le from the provisioning TFTP server
every 24 hours, but these settings can be adjusted per the tables below by placing the respective
SNMP varbinds into the modem’s DOCSIS conguration le.

4.11.2 QAM Constellation Common Impairments
The tables on the right hand side of the screen provide a summary of common parameters
associated with QAM Constellation analysis. Here’s a breakdown of the parameters listed:
• Frequency – Downstream frequency given in MHz.
• Power – Downstream power given in dBmV.
• Modulation – Modulation type associated with the downstream channel.
• Lock Status – Current cable modem connectivity state.
• Channel ID – CMTS identication of the downstream channel within this particular MAC interface.
• SNR / (RxMER) – Downstream signal quality. Modulation Error Ratio (SNR)
• Pre FEC CER – Codeword Error rate (CER) BEFORE forward error correction is applied.
• Post FEC CER – Codeword Error rate (CER) AFTER forward error correction is applied.

5.0 Upgrading Firmware
5.1 Upgrading DSM3 Series Modem Firmware
The rmware is upgraded using standard DOCSIS methods as dened in RFC4639.
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 Conguration File, stored on the TFTP root directory.
Both methods are explained below.
5.1.1 Identifying the Modem and Obtaining Firmware Files
The cable modem rmware in the DSM3 Series requires its own rmware and manufacturer's
Code Verication Certicate (CVC le).
Contact Alpha Technologies to obtain the latest rmware and manufacturer's CVC les.

6.1 SCTE-HMS MIBs
The DSM3 Series remotely reports power supply data and alarms using the Simple Network Management
Protocol (SNMP) over the DOCSIS (Data Over Cable Service Interface Specication) communications standard.
The DSM3 Series typically reports into a centralized Network Management System (NMS) through a standard
collection of data access points referred to as the SCTE-HMS Management Information Bases (MIBs). The NMS
polls the DSM3 Series for power supply data with the option of having the DSM3 Series send SNMP traps in the
event that an alarm condition occurs. In addition to the SCTE-HMS MIBs, the DSM3 Series also supports the
Alpha proprietary SNMP MIBs, which allows direct access to the power supply as well as the ability to change
Communications Module settings.
The following MIB (Management Information Base) les are required for the NMS or SNMP Manager to collect
data from the Communications Modules. These les can be found on the Society of Cable Telecommunications
Engineers (SCTE) Web site www.scte.org. There are dependencies between MIB les so they should be compiled
in the order listed below:

6.2 SCTE-HMS MIB Alarms
6.2.1 SCTE-HMS Congurable Alarms
The HMS discrete and analog alarms provide the capability to monitor and alarm various
power supply and environmental conditions and measurements. The alarms in the SCTE-
HMS propertyTable and the discretePropertyTable can be dened and set to provide a custom
monitoring system.
The following section provides an example and detailed information on how to set values, enable
or disable alarms in the MIB tables. For ease of reference they are in this sequence:
• An example of how set a temperature alarm
• A table to help convert the desired reported alarm states to hexadecimal for setting the MIB
• Commonly monitored parameters and recommended values
Example:
The alarms for psTemperature below are set so that the normal temperature range is from
30°C to 45°C. If the temperature rises above 45°C, a casHI alarm will be sent to the alarmTable.
Anything over 50°C is considered a critical condition and will generate a casHIHI alarm. If the
temperature falls below the normal level of 30 degrees and casLO will be generated and if it
continues to drop below 0, a casLOLO will be generated. The temperature must rise above the
LOLO limit plus the deadband value of 3°C before the casLOLO alarm will change to a casLO.
The alarmEnable eld is set to 0F Hex to monitor and alarm for all conditions.

DSM3 Alarm Cloning & Distribution
SCTE-HMS Alarm settings can be distributed automatically to all DSM3 Communications
Modules on the network. Use the following procedure to congure and distribute the alarm
settings.
1. Select the desired SCTE-HMS alarm settings on a master DSM3.
The SCTE-HMS-PROPERTY MIB denes a method for setting thresholds for analog and discrete
values that can be used for setting traps or alerting a Network Management System when those
thresholds are compromised. There are two SCTE-HMS SNMP MIB Tables where these values
are congured:
propertyTable OID: 1.3.6.1.4.1.5591.1.1.1
This table is used for setting thresholds for analog properties such as input & output voltages,
individual battery voltages, currents and temperature.
discretePropertyTable OID: 1.3.6.1.4.1.5591.1.1.3
This table is used to set alarm parameters on discrete conditions such as tamper on/off, major/
minor alarms and various inverter status conditions.
Full explanations of these MIB tables and their settings can be found by reading the SCTE-HMSPROPERTY MIB. The MIB table alarm settings can be changed to desired values using a SNMP
MIB browser or status monitoring software. Once the tables are congured with the desired alarm
settings, proceed to Step 2 on exporting the “AlarmSettings.acf” le.
2. Export the “AlarmSetting.acf” le of the master DSM3’s alarm settings.
2.1. Connect to the Web page of the master DSM3.
2.2. Navigate to the Advanced Conguration menu and select the HMS Alarms page.
2.3. Verify the alarm settings dened in Step 1 are displayed in the propertyTable and discrete ProperyTable.
If further changes to the alarm settings are required, refer to Step 1.
2.4. Click on the Export button at the bottom of the HMS Alarms page.
2.5. When prompted, refer to Section 4.3.1, Web Interface Security Levels for the applicable User Name and Security Password.
2.6. Download the “AlarmSettings.acf” le to the TFTP root directory.
If desired, the le may be renamed.

3. Distribute the “AlarmSettings.acf” le to other DSM3s.
The “AlarmSettings.acf” le is distributed to other DSM3s by setting the following Alpha MIB
parameters to the indicated values. This can be done to an individual DSM3 using a MIB browser,
or to multiple DSM3s by placing the SNMP OIDs into the modem’s DOCSIS conguration le or
the proprietary atidoc03.cfg conguration le.
Verify the DSM3s’ SCTE-HMS property tables have been updated by viewing the DSM3 HMS
Alarms Web Page, status monitoring system or SNMP MIB browser.

6.0 Data Management
6.2.2 SNMP Traps
Use of SNMP Traps allow the network manager to set conditions (alarms) under which the device
(or devices) autonomously report to the headend the existence of the pre-congured event. The
type of event determines the level of action to be taken.
1. Verify the IP address of the trap destination server(s) has been congured.
If the trap destination server requires conguration, refer to Section 3.3.3, Setting SNMP
Trap Destination Addresses for instructions.
2. Alarms must be congured. SNMP alarm traps sent by the Communications Module are
formatted according to the SCTE-HMS-ALARM-MIB specication with the following
information included:
SNMP Trap community string:
commonTrapCommunityString, OID 1.3.6.1.4.1.5591.1.3.1.11.0
Default value is "public"
Example Alarm Trap
The example below is a psTamper alarm trap indicating a discreteMinor alarm: Tamper is open.
Data from the raw trap will appear as shown below. Refer to Table 6-6, SNMP Alarm Trap
Varbinds and Explanations, for denitions of the varbinds.
Optional user-congurable parameter that is often used to provide a unique logical name, or even
the physical address of where the Communications Module is installed.
This varbind was designed by the SCTE-HMS committee with the intention of being used by
sophisticated trap interpreters. The information is “coded” within the octet strings:
Octet 1-4: POSIX Time of alarm occurrence (most signicant byte rst)
Octet 5: Alarm Type (See description below)
Octet 6: Contents of commonNeStatus immediately after alarm occurred
Most trap interpreters cannot decode this message, which is why varbinds 4 and 5 were added that
provide the same information in a more useable format.
This eld provides the varbind of the parameter that is alarming along with the value of that
parameter. This is the same information encoded in varbind #3 Octets 7 through Z.
In the example above the value would be:
This is the information from varbind #3 Octet 5 above. The alarm location will always be the
SCTE-HMS currentAlarmAlarmState and the type will be determined based on how the alarm was
congured in the SCTE-HMS PropertyIdent MIB tables.
OID 1.3.6.1.4.1.5591.1.1.2.1.2.0 (currentAlarmAlarmState)
Type: 1-7 based on SCTE denitions:
1 NOMINAL
2 HIHI
3 HI
4 LO
5 LOLO
6 Discrete Major
7 Discrete Minor
The Type will be determined by how the alarm is congured in the SCTE-HMS PropertyIdent MIB,
whether it is a Discrete or Analog alarm and the level of alarm dened for that state.
Table 6-8, SNMP Alarm Trap Varbinds and Explanations
Trap on Normal
The DSM3 Series has the capability of sending a “return to normal” trap once an alarmed condition
returns to a normal state. This feature is enabled by default, but can be disabled by setting the
"TRAP ON NORMAL" parameter in the the MIB point atiMgmtSnmpTrapOnNormal to a value of "2".
The contents of this trap message will be identical to the SNMP Alarm traps, but the value of the
Alarm "Type" dened in the 5th varbind will be "1" (NOMINAL).
SCTE-HMS Warm-Start Trap
In addition to the SNMP alarm traps, the DSM3 Series will also send an SCTE-HMS warm-start
trap when it is initialized. Some SNMP monitoring software requires this trap for auto-identication
of the Communications Module. The format of this trap will be similar to the alarm trap, but the only
information sent will be:
commonTrapCommunityString, OID 1.3.6.1.4.1.5591.1.3.1.11.0
commonPhyAddress, OID, 1.3.6.1.4.1.5591.1.3.2.7
commonLogicalID, OID 1.3.6.1.4.1.5591.1.3.1.1.0
SCTE-HMS Cold-Start Trap
An SNMP-HMS cold-start trap will be generated by the DSM3 Series anytime it initializes with a
new rmware version. In addition, a cold start trap is sent whenever the DSM3 conguration has
changed. If any parameter in the HMS PROPERTY table has changed since the last reset, a
cold-start trap will be sent upon the next reset.

6.2.3 General Power Supply Alarms
General power supply alarms are passed directly from the power supply to the Communications
Module without specic denition and are classied in the HMS MIB table as psMinorAlarm
and psMajorAlarm. There are a number of problems that can generate these alarms and the
exact nature of the situation is not specied. Minor and Major alarms are dened by the SCTE
standards committee as follows:
psMajor
“Service has been dropped or a service interruption is imminent. Indicates that an immediate
truck roll is appropriate.” Several psMajor alarms are latching, meaning that the alarm won’t
clear until the problem is xed and after a successful completion of a self-test. A self-test is the
preferred method of verifying the resolution of the alarm condition as cycling the power has the
potential of masking the problem and not indicating the actual state of the system.
psMinor
“A non-service affecting condition has occurred and should be monitored.”
The following table lists the psMajor and psMinor alarm denitions for the XM2 power supply.
NOTE:
The cause of a psMajor or psMinor alarm can be determined by checking the Discretes table in the Alpha MIB
or by viewing the Web page. The cause will have the value of “ALARM.”

7.0 Installation
7.1 Verifying Power Supply Device Address
Before installing the hardware, provision the DHCP server with the cable modem’s RF MAC Address. This
allows the installation to be veried while the technician is on-site, eliminating the need for a second visit if
there are problems with the installation.
WARNING!
To reduce the risk of electric shock, completely remove the inverter module from the power
supply prior to installation. For eld installation, use a service power supply to avoid losing
power to the load.
CAUTION!
The DSM3 Series is static sensitive. An ESD wrist strap should be worn when installing the
Communications Module.
Before removing the Inverter Module (IM), verify the power supply device address is correct.
The power supply device address must not be set to zero and no two power supplies monitored by a
single DSM3 Series can have the same address. Power supplies must have 1, 2, 3, 4 or 5 as an address.
To verify the power supply’s address do the following:
Smart Display Screen
1. Press the Enter key on the inverter module twice to access the SETUP Menu.
2. Press the Down key until DEVICE ADDRESS is displayed.
3. If the address is correct (in the range of 1 to 5), skip to Step 8.
4. To change the address, press the Enter key to enter the Edit mode.
5. Press the Up or Down keys until the desired address (1, 2, 3, 4 or 5) is displayed. Remember, each
power supply monitored by a single Communications Module must have a unique address; this may
require accessing the menu systems of the additional power supplies and adjusting as applicable.
6. Press the Enter key to load the new address.
7. Press the Enter key again to accept the new data.
8. Press ESC three times to return to the OPERATION NORMAL screen.

7.9 I/O Connections (TPR, ENV)
The Alpha DSM3 series transponders (DSM3, DSM3x, DPM) are all populated with a Tamper interface to
report the status of the power supply enclosure door when equipped with the optional tamper switch. The
Alpha DSM3x and DPM are populated with the Environmental and I/O Controller interface (referred to in
this section as I/O Port) which can be used to monitor and control an array of contact relay devices such
as battery heater mats, enclosure moisture sensors and emergency generators.
7.9.1 Tamper (TPR) Switch Interface
I/O Control Interface (ENV)
Tamper Switch Interface (TPR)
The tamper switch interface is designed to report and alarm the status of the power supply
enclosure door. The circuit created by the tamper switch is a contact relay, so other contact relay
devices can be designed to be monitored through this interface. For example, the Alpha Utility
Line Sensor (Alpha P/N 746-399-20) uses the tamper interface to monitor the Utility outlet to
report the presence of line voltage.
NOTE:
In the OID column of the following table, ‘X’ denotes power supply device address (Default = 1)

2. Congure alarms (Generic Only – See below section for details)
3. Monitor appropriate SNMP parameters (See each section below for details)
7.9.3 Conguring I/O Port Connections
Alpha has created logic for control and reporting of specic devices or combination of devices.
The Alpha proprietary SNMP MIB atiMgmtSysIoSelect, 1.3.6.1.4.1.926.1.3.2.8.1.0 must be
set appropriately before the device status will be correctly reported. The monitored device can
also be set through the DSM3x/DPM “Advanced Conguration - I/O” Web page pull-down.
The status of the generic I/O Pins can still be monitored and alarmed via the SCTE-HMS
discretePropertyTable even when specic devices have been selected.

The I/O connector on the Alpha DSM3x and DPM allow the headend to remotely monitor and
control external contact relay devices. Each input pin can be congured through the SCTE-HMS
discretePropertyTable for alarm and SNMP trap generation.
7.9.6 Conguring and Monitoring a Generic I/O Device
The I/O cable P/N 875-627-25 is designed to monitor a single contact relay device through Pin
6 of the ENV connector. The I/O cable P/N 875-627-22 is designed to control a relay device
through Env Pin 3 and also monitor a contact relay through Pin 4. For any other generic device
congurations consult your Alpha representative.
Set the parameter atiMgmtSysIoSelect 1.3.6.1.4.1.926.1.3.2.8.1.0 to a value of “1” (Generic).
Alternatively, navigate to ‘Advanced Conguration’, ‘I/O – Environment’ and select “Generic
Device” from the pull-down list.
The status of the control and input pins can be monitored through the following OIDs:
Pin 3 (Control)
1.3.6.1.4.1.926.1.3.2.8.20

7.0 Installation
7.9.8 Lightning Arrestor (LA-P-SM) Installation
The physical installation of the LA-P-SM is shown below and consists of connecting the cable (Alpha
p/n: 875-627-23) from the LA-P-SM's two leftmost screw terminals to the six pin ENV connector on the
DSM3 Series or DPM and plugging the LA-P-SM into the enclosure‘s power outlet.
1. Insert cable into 3-pin connector
7.9.9 Conguring the LA-P-SM
Set the parameter atiMgmtSysIoSelect 1.3.6.1.4.1.926.1.3.2.8.1.0 to a value of “2” (LA-P-SM).
Alternatively, navigate to ‘Advanced Conguration’, ‘I/O – Environment’ and select “LAP Only”
from the pull-down list.
The status of the LA-P-SM can be monitored through I/O – Environment web page or via the
notInstalled(1)NO LAP INSTALLED. This would be the case if the OID atiMgmtSysIoSelect has not been set to a value of 2.
ok(2)OK. Indicates that each connected power supply detects AC input and the LAP device reports no fault. Normal
operation.
acNotPresent(3)AC OFF. One or more of the power supplies detects no AC. To check if the LAP has failed, query the OID
psInputVoltagePresence (1.3.6.1.4.1.5591.1.4.2.1.34) to ascertain if the line has truly failed; if this is the case, the
LAP is working normally. If the line is OK, it is likely the LAP has a problem.
relpaceLap(4)Critical Surge Event - Replace LAP. An LAP has failed and should be replaced. This is the state when all power
supplies detect AC but the LAP sense line indicates a fault.
invalid(5)There is a fault, either the LAP has not been wired correctly or the relay in the LAP is stuck in the no-fault state. This
state occurs when at least one power supply senses AC fail, which should cause an LAP fault, but no fault is detected
(this would be the case if the LAP relay is stuck in the ON condition).
4. Plug LA-P-SM into power outlet
5. Plug cable into ENV connector

9.3.1 Detailed LED Descriptions
After power is applied or a reset occurs, all LED's will ash in certain patterns indicating the cable
modem chipset is starting or restarting. Once it is ready it will begin the DOCSIS requirement of
searching for the downstream frequency lock and the LED's will follow the detailed descriptions
below.
ALM/RDY - Alarm/Ready
The ALM/RDY - During normal operation, this LED blinks GREEN, indicating a heartbeat pulse
from the processor. The frequency of ashing by this LED provides a visual alert for power
supply discrete major and minor alarms, if congured in the property and discrete property tables
of the SCTE-HMS MIB. The ALM LED (RED) is factory defaulted OFF. Refer to Section 6.3
for information on conguring the DSM3 Series for active monitoring and alarming. If an event
triggers an HMS alarm, the ALM/RDY LED blinks RED according to the alarm type until the alarm
has been resolved. For a minor alarm, the frequency of ashing (RED) will be more OFF than
ON and for a major alarm the frequency of ashing will be (RED) more ON than OFF. If there are
multiple active alarms, including one or more major alarms with one or more minor alarms, the
major alarm will take precedence in terms of the indication.

REG - CM Registration
Once a downstream channel has been negotiated between the CM and CMTS, the modem
attempts to register with the DHCP server and obtain the conguration le. This LED ashes
while the process takes place. Once the registration is complete, the LED will remain on solid.
This is the best indication that the DSM3 Series is communicating with the CMTS in the headend.
DS - Downstream Communication
This LED indicates the state of the CM's attempt to gain a downstream signal. This process may
take several seconds, depending on how long it takes the CM to locate a carrier signal and lock
onto a channel. The LED ashes while searching for the downstream DOCSIS channel and is on
solid when the downstream channel is locked.
ACT - CPE Activity
The CPE activity LED ashes to indicate that data is being transmitted or received between the
DSM3 Series and a network device.
LNK - Network Communication Status
The Ethernet link LED remains ON when there is an active connection on the Ethernet port (e.g.,
a computer is connected for local diagnostics).
Rx/Tx Power
The Rx/Tx PWR LED utilizes a tricolor LED to provide the installer a quick verication of the
modem transmit (Tx) and receive (Rx) RF power levels. The Rx/Tx PWR LED will illuminate
“green” when both the cable modem Tx and cable modem Rx RF power levels are within the
range as specied in the SCTE-HMS PropertyTable. The LED indicator illuminates “blue” when
Rx and/or Tx levels are within the “warning” range as specied by the SCTE-HMS PropertyTable.
The LED indicator illuminates “red” when Rx and/or Tx levels are outside the range as specied
by the SCTE-HMS PropertyTable.

careful not to exceed the Input Level and Output Power range specications of the DSM3 Series
Communications Module.
COM - AlphaBus Communications
The COM LED indicates any data trafc being received by the DSM3 Series through the COM
(AlphaBus) port. This LED will also blink with one to three blinks approximately every 10 seconds,
which indicates communication exists between the DSM3 Series and other connected devices,
such as a generator or additional XM2.
BAT A/B - Battery Strings A & B
The LED indicator remains ON solid when the battery string wiring harness is correctly connected
to the batteries and the Bat A/B connector on the DSM3 and DSM3x Series.
BAT C/D - Battery Strings C & D
The LED indicator remains ON solid when the battery string wiring harness is correctly connected
to the batteries and the Bat C/D connector on the DSM3x.
9.3.2 Resetting the Communications Module
Should the need arise to reset the Communications Module locally, such as in the case of adding
additional power supplies, a generator, or carrying out maintenance activities, do the following:
Press and hold the reset button (RST) for approximately three (3) seconds until the ALM/RDY
LED stops blinking and turns solid (green). Release the button. The Communications Module will
perform its power up sequence.
9.4 Verifying Communications via the Headend
Using SNMP, check connectivity by verifying power supply data by doing the following:
• With a MIB browser check power supply data in the psIdent MIB branch (1.3.6.1.4.1.5591.1) of the
SCTE-HMS tree.
• With network management software, verify the DSM3 Series has been identied and is reporting data
correctly.

13.0 Dual IP Mode (Addendum)
13.1 Overview
The DSM3 Series can operate in either Single (default) or Dual IP Mode. In Single IP mode, 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. In Dual IP mode, the Communications Module acts like a CPE device
to the cable modem and registers a second IP address on the public CPE network.
The following table lists some of the common characteristics of the DSM3 Single IP and Dual IP
congurations:
Single IPDual IP
NetworkAll 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.
Data AccessThe Network Management System requires
access to the same private modem network.
SecurityCommunication with the Communications
Module is limited to the private LAN network,
and is very secure.
IP AddressesWhere the IP address pool is limited, there is
no need to issue the Communications Module
a CPE IP address. Only one (1) IP Address is
required for the cable modem of the DSM3.
Data ManagementAccess to the Communications Module is
limited to the private LAN network making data
management less versatile, especially for eld
personnel.
Table 13-1, Single IP Mode versus Dual IP Mode
The Communications Module acts like a CPE device to
the cable modem and registers a second IP address on
the public CPE network.
Dual IP mode allows the power supply data to be
accessed and managed from anywhere within the
public (CPE) network.
Since the Communications Module is a CPE on the
public network, access may be less secure.
The CPE requires its own IP address, which may be
in short supply. A total of two (2) IP addresses are
required, one for the cable modem and one for the
Communications Module.
The Communications Module is accessible on the
public (CPE) network. This makes data management
more versatile for eld personnel.
One CM IP address only accessible on the private (LAN)
network with access to both CM and Communications
Module data.

To easily determine the conguration of the Communications Module when viewing it on its web page,
check the Conguration Line as well as the entries for the CM and CPE addresses. A single IP
Communications Module will display a CM MAC address only, while a dual IP Communications Module
will also indicate a CPE address.

13.3.1 atidoc03.cfg in Dual-IP Mode
NOTE:
Refer section 3.3.8 for details on using the atidoc03.cfg le to propagate custom settings to
eld-deployed DSM3 Series Communications Modules.
In Dual-IP mode, the DSM3 Series will rst attempt to download the proprietary conguration
le atidoc03.cfg through the CPE’s interface from a TFTP server on the CPE network. In many
networks, the TFTP server is blocked or disabled, so the DSM3 Series also has provisions to
download this le through the Cable Modem interface from the modem’s provisioning server if
necessary. The lename and TFTP server location may also be specied through special tags in
the DHCP Offer, refer to section 13.3.3 for details. Similiar to Single-IP mode, any DSM3 Series
proprietary SNMP MIB setting may be placed in the modem’s DOCSIS conguration le which
would eliminate the need for atidoc03.cfg.

13.4 Dual IP SNMP Community Strings
The Communications Module community strings used for the CPE Communications Module in Dual IP
mode can be congured by the operator. The default Communications Module read-only community string
is AlphaGet. The default read-write community string is AlphaSet. These settings can be congured with
the DOCSIS Conguration File, the DSM3 Setup File (aitdoc03.cfg) or remotely using SNMP by including
the parameters below:
NOTE:
These community strings are only applicable for CPE access in Dual IP mode. CM access in both Single
IP and Dual IP modes use standard DOCSIS community strings set through the modem conguration le's
docsDevNmAccessTable. See Section 3.3.8.

13.5 Security in Dual IP Mode
[desired value]
[desired value]
In Dual IP Mode, additional SNMP security to the DSM3 Series proprietary MIBs is required since the
Communications Module and power supply data is exposed on the CPE network, which may be more
vulnerable to packet snifng and community string deciphering than on the secure cable modem network.
There are two methods of providing SNMP Security in Dual IP Mode: the Data Access Key (Default), and
the Secure Access List.
Method 1: Dual IP Security Using the Data Access Key
In Dual IP Mode atiMgmtSnmpAlphaSetAccess is the only SNMP parameter within the Alpha
proprietary MIB with SNMP-write access on the CPE network by default. When this parameter is
set to the value of the parameter atiMgmtSnmpAlphaSetKey, the data access key, SNMP read/write
access is granted to all parameters in the Alpha MIB tree with read/write attributes. When this access
is granted, the value of atiMgmtSnmpCPESetEnabled is automatically changed to "2" (enabled). After
the operator is nished setting the SNMP variables, SNMP write access can be disabled by setting the
atiMgmtSnmpCPESetEnabled to "1" or by setting atiMgmtSnmpAlphaSetAccess to any value other than
the data access key or by performing a reset to the DSM3 Series.
The data access key parameters can be changed from the default values through the DOCSIS
Conguration File, the DSM3 Series Setup File (atidoc03.cfg) or remotely using SNMP by including the
following Alpha MIB parameters:
MIB ParameterObject IDDescriptionValue
atiMgmtSnmpAlphaSetAccess1.3.6.1.4.1.926.1.3.1.3.3.0Set to Access KeySet to match the value of
atiMgmtSnmpCPESetEnabled1.3.6.1.4.1.926.1.3.1.3.5.0Corresponds to whether
or not the action taken on
atiMgmtSnmpAlphaSetKey was
successful. Once enabled, writing
1 to this variable will disable CPE
sets.
1 = Disabled (False)
2 = Enabled (True)

Method 2: Dual IP Security Using the Secure Access List
The DSM3 provides an alternative method of providing additional SNMP security in Dual IP by limiting access to
the Communications Module’s CPE address. The Secure Access List method limits remote SNMP access to four
IP addresses. Only the IP addresses listed in the SNMP Access Table are able to read or write to the Alpha MIB
parameters from the public (CPE) network. This method overrides the default "Data Access Key" method.
The IP address entries in the SNMP Access Table can be set through the DOCSIS Conguration File, the DSM3
Setup File (atidoc03.cfg) or remotely using SNMP by including the following Alpha MIB parameters:
