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 specications.

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 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 (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 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 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.

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 modied 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 Conguration and Installation

NOTE:

Before installation, read all of Section 2.0, Overview.

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 (IPv4), or through SNMPv3 Notication 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, 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 CM MAC address with a DOCSIS Conguration File to

set modem communication options. (See Section 3.3, The DOCSIS Conguration File for instructions

on how to create a DOCSIS Conguration 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 Conguration

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.

3.0 Network Conguration

3.3 The DOCSIS Conguration File

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 start up 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 to sample entries below). 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 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 = 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

every 24 hours. However, these settings may be adjusted per the tables below by placing the

respective SNMP varbinds into the modem’s DOCSIS conguration 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 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

• Cookies

• ActiveX Controls

• Downloads

• Active Scripting

• Show Pictures

These settings are typically enabled in the Web Browser by default.

Fig. 4-1, DSM3 Series Web Page

(data values shown for illustration purposes only)

1. Connect a standard Ethernet cable (CAT5) between the DSM3 Series Communications

Module Ethernet port (ETH) and a laptop or computer’s network interface port.

2. Launch a Web browser.

3. Enter the Communications Module's default IP address (192.168.100.1) or the DHCP assigned

IP address into the Web browser’s address eld.

6.0 Data Management

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 Specication) 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

6.2 SCTE-HMS MIB Alarms

6.2.1 SCTE-HMS Congurable 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 dened and set to provide a custom

monitoring system.

The following section provides an example and detailed information on how to set values and enable or disable alarms in the MIB tables. For ease of reference they are in this sequence:

• An example of how to 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°C, 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 congure and distribute the alarm

settings.

discreteMinor

1. Select the desired SCTE-HMS alarm settings on a master DSM3.

The SCTE-HMS-PROPERTY MIB denes 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 congured:

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 congured 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 Conguration menu and select the HMS Alarms page.

2.3. Verify the alarm settings dened 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 conguration le or the proprietary atidoc03.cfg conguration le.

MAC address of the Communications Module

Optional user-congurable 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 signicant byte rst) Octet 5: Alarm Type (See description below)

Octet 6: Contents of commonNeStatus immediately after alarm occurred

Octet 7-m: Alarm Object Identier (BER encoded) Octet n-z: Alarm value (BER encoded)

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:

OID: 1.3.6.1.4.1.5591.1.4.2.1.27.1.0 (psTamper) Value: 2 (Open)

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

congured 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 denitions:

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 congured in the SCTE-HMS PropertyIdent MIB, whether it is a Discrete or Analog alarm and the level of alarm dened for that state.

Table 6-7, 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 dened 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-identication

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 conguration

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

The Intelligent CableUPS detects a wide array of alarms and displays the type of active alarm in

the Smart Display screen and the severity of alarm (e.g., Major/Minor) by means of the Inverter

Module LEDs.

General power supply alarms are passed directly from the power supply to the Communications

Module without specic denition and are classied 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 specied. Minor and Major alarms are dened 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 denitions for the XM3 power supply.

7.0 Installation

7.1 Verifying Power Supply Device Address

Before installing the hardware, provision the DHCP server with the cable modem’s CM MAC address. This allows the installation to be veried 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. The power supply must have a unique address to

communicate with a system controller. The system controller uses the address as an identier to query the power supply for information. Each power supply on the same communications bus must be identied with a value between 1 and 5. To verify the power supply’s address do the following:

EDIT USING ↑ ↓ <ENTR>

DEVICE ADDRESS

ESC

Smart Display Screen

1. Press the PWR key on the Inverter Module twice to access the PWR CNFG Menu.

2. Press the Down or Up 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 to 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 ESC two times to return to the OPERATION NORMAL screen.

7.2 Installation / Replacement Procedure in XM3 Power Supplies

If the XM3 CableUPS has been shipped without a DSM3 Series module, or the existing module requires removal and replacement, do so via the the following procedure:

1. Switch OFF the Inverter Module battery breaker.

NOTE:

With the battery breaker in the OFF position, the power supply will not go into inverter mode.

2. Unplug all Inverter Module connections (e.g. battery cable, remote temperature sensor).

3. Loosen the two Inverter Module thumbscrews.

4. Slide the Inverter Module out of the power supply.

5. If the Inverter Module is equipped with a Communications Module, remove it by loosening the two Phillips captive screws.

6. Line up the 18-pin mating connectors on the DSM3 Series and the XM3 Inverter

Module. Gently push the DSM3 Series into the Inverter Module until the 18 pin mating connector is properly seated.

Fig. 7-3, Connecting the Communications Module to the Inverter Module

7. Fasten the DSM3 Series to the Inverter Module by tightening the two captive screws. It

is recommended that the screws be tightened alternately, a few turns at a time so the Communications Module aligns in parallel to the Inverter Module.

8. Reinstall the Inverter Module and tighten the two thumbscrews. Make front panel

connections (tamper, temperature sensor, battery sense, RF etc.).

9. If not yet done, record the cable modem MAC address from the front of the unit and report it to

the network manager for network provisioning.

7.8 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.

7.8.1 Tamper (TPR) Switch Interface

I/O Control Interface (ENV) Tamper Switch Interface (TPR)

Fig. 7-9, I/O (ENV) and Tamper Switch Interface (TPR) Connection Locations

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 746-399-2X) uses the tamper interface to monitor the Utility outlet to

report the presence of line voltage.

5 = Heater/Cooler + LAP

6 = DC Generator + LAP

The device can be selected through the Web page by navigating to ‘Advanced Conguration’, ‘I/O – Environment’ and selecting from the pull-down list

2. Congure alarms (Generic Only – See below section for details)

3. Monitor appropriate SNMP parameters (See each section below for details)

7.8.3 Conguring I/O Port Connections

Alpha has created logic for control and reporting of specic 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 Conguration - 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 specic devices have been selected.

atiMgmtSysLAPState (1.3.6.1.4.1.926.1.3.2.8.2)

Value list Description

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 LEDs 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 LEDs 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 congured in the property and discrete property tables of the SCTE-HMS MIB. The ALM LED (RED) is factory defaulted OFF. Refer to Section 6.2.3, General Power Supply Alarms for information on conguring 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.

9.0 Start Up and Verication

9.3.1 Detailed LED Descriptions

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 Conguration File. 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 verication 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 specied in the SCTE-HMS PropertyTable. The LED indicator illuminates blue when Rx and/ or Tx levels are within the warning range as specied by the SCTE-HMS PropertyTable. The LED indicator illuminates red when Rx and/or Tx levels are outside the range as specied by the

SCTE-HMS PropertyTable.

Refer to the following table for default ranges in the SCTE-HMS PropertyTable:

Parameter alarm Enable HiHi Hi Lo LoLo Deadband

* Values in ( ) denote behavior of the Rx/TX LED if alarmEnable bits are set to ‘00’.

150 100 -100 -150 15

550 500 00 00 15

Table 9-1,SCTE-HMS Property Table

By default, alarmEnable is set to 00 (disabled) to prevent unwanted SNMP traps but the LED

behavior will function as if the alarmEnable were set to the values in the above table. If the alarmEnable bits are set to anything other than 00, the LEDs will then follow the behavior of the desired enable bit setting.

The above default values translate into the following Rx/Tx Power LED color ranges:

LED Color Rx Range (dBmV) Tx Range (dBmV)

Green +10 to -10 0 to +50

Blue +15 to +10 and -10 to -15 +50 to +55

Red >+15 and <-15 >+55

Table 9-2, Rx/Tx Power LED Color Ranges

In addition to the above SCTE-HMS PropertyTable entries, the Tx and Rx levels displayed on the DSM3 Series Web page will each provide colored indicator bars that correlate to the RF LED and SCTE-HMS PropertyTable thresholds.

9.0 Start Up and Verication

9.3.1 Detailed LED Descriptions

Rx/Tx Power

The current RF level status for both the Rx and Tx will be displayed on the colored scale

highlighted in black, providing verication of modem RF power levels. Refer to the gure below

for an example of the RF power level indicator bars on the Web page.

Conguring the Rx/Tx Power LED - Custom Settings

Fig. 9-5, DSM3 Series Web Page, RF Power Level Indicators

If desired, the RF Power Level ranges for the Rx/Tx PWR LED may be customized via

SNMP by adjusting the HiHi, Hi, Lo, LoLo values for the docsIfDownChannelPower and

docsIfCmStatusTxPower in the SCTE-HMS Property Table (OID:1.3.6.1.4.1.5591.1.1.1). Be careful not to exceed the RF Input Power and Output Power range specications of the DSM3

Series Communications Module.

COM - AlphaBus Communications

The COM LED indicates any data trafc being received by the DSM3 Series through the COM (AlphaBus) port. This LED will also blink one to three times approximately every 10 seconds,

which indicates communication exists between the DSM3 Series and other connected devices, such as a generator or additional XM3.

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 identied 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

congurations:

Single IP Dual IP

Network All 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 Access The Network Management System requires

access to the same private modem network.

Security Communication with the Communications

Module is limited to the private LAN network, and is very secure.

IP Addresses Where 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 Management Access 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.

13.2 Web Comparison, Single IP Mode/Dual IP Mode

To easily determine the conguration of the Communications Module when viewing it on its web

page, check the Conguration 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.

Displays CM MAC address only

13.0 Dual IP Mode (Addendum)

13.3 Conguring Dual IP Mode

To switch the DSM3 Series Communications Module from Single to Dual IP mode the atiMgmtSnmpSnmpCPEAccess parameter of the Alpha MIB will need to be enabled. The Dual IP enable

setting can be set through the DOCSIS Conguration File, the DSM3 Setup File (atidoc03.cfg), the

Provisioning Mode via the Communications Web page or remotely using SNMP by setting the following Alpha MIB:

MIB Parameter Object ID Description Value

atiMgmtSnmpSnmpCPEAccess 1.3.6.1.4.1.926.1.3.1.3.6.0 Enables/Disables the

The CPE Communications Module IP can be assigned its IP, Subnet Mask and Gateway Addresses either

via DHCP (default) or manually, either through the web page or via the below SNMP settings:

NOTE:

After conguring the Static settings the Communications Module must be reset in order for the settings to

take effect.

this is the IP address to which the CPE will respond.

atiMgmtSysMonitoringCpeStaticMask 1.3.6.1.4.1.926.1.3.2.2.5.2.3.0 When the CPE IP address is

static, this is the subnet mask.

atiMgmtSysMonitoringCpeStaticGateway 1.3.6.1.4.1.926.1.3.2.2.5.2.4.0 When the IP address is static,

this is the IP address of the gateway.
