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

7

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 transponder’s data.

The IDH4 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 IDH4 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 transponder parameters can be monitored and set locally using a personal computer and a standard
Ethernet cable.

The IDH4 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 IDH4
Series’ cable modem communicates directly with the CMTS.

The Dynamic Host Control Protocol (DHCP) server needs to be provisioned with the IDH4’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 transponder's Web page by placing its IP address
into a standard Internet Web browser.

2.0 Overview

2.2 Network Connectivity

The IDH4 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 transponder 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.

00:26:97.

• 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.

IDH4 Series installation and setup is comprised of three basic steps:

1. Conguring the Network: Provisioning the DHCP Server with the transponder’s MAC Address and
assigning it a DOCSIS Conguration File.

2. Setting Options: The IDH4 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 IDH4 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 transponder and power supply parameters.

3. Field Installation of the IDH4 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 3.2 for instructions on how to create a DOCSIS

Conguration File).

The RF and CPE MAC addresses are located in two places on the IDH4 Series and on the packing slip,
see below.

3.2 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 le in the TFTP root directory.

To build a DOCSIS Conguration File use a DOCSIS TLV editor program.
See the example Conguration File in Section 3.2.3.

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.

3.2.1 Setting Modem Community Strings

Set the modem community strings with the DOCSIS Conguration File by including the following

SNMP parameters:

MIB Parameter Object ID Description Value

docsDevNmAccessIp 1.3.6.1.2.1.69.1.2.1.2.x The IP address (or subnet) of the

network management station

3.0 Network Configuration

3.2 The DOCSIS Conguration File

3.2.4 Proprietary Conguration File ‘idhdoc04.cfg’

The IDH4 Series will attempt to download a TLV-formatted le ‘idhdoc04.cfg’ from the modem’s

provisioning TFTP server at start up and every 24 hours thereafter. The idhdoc04.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 IDH4 Series transponders.

The idhdoc04.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
IDH4 Series transponders.

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 3.2, 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 idhdoc04.cfg
proprietary conguration le.

To build the idhdoc04.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 (see sample entries below). The IDH4 Series proprietary
conguration Setup le must be named “idhdoc04.cfg” and placed in the root directory of the TFTP
server. IDH4 settings are updated according to values dened in this le at start up and after every 24

hours of operation.

Sample idhdoc04.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

3.2.5 Changing Default idhdoc04.cfg Download Settings

By default the IDH4 Series will download the idhdoc04.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.

Overview

The IDH4 Series power supply transponder 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 IDH4 Series transponder’s Ethernet port (comparable to the Craft port on some transponder models)

will typically be used as a local connection point allowing the user to connect directly to the IDH4 Series

Web server interface to verify/congure common communication parameters and view power supply

status and battery values. The Ethernet port on the IDH4 Series is a fully functional standard Ethernet
port, capable of providing all the functionality of any standard Ethernet connection.

To access the IDH4 Series transponder Web server locally utilizing a Web browser, follow the procedure
outlined below:

1. Connect a standard Ethernet cable (CAT5) between the IDH4 Series transponder Ethernet port (ETH)
and a laptop or computer’s network interface port.

2. Launch a Web browser.

3. Enter the transponder's default IP address (192.168.100.1) into the Web browser’s address eld.

4. The transponder’s Web server home page will appear (Fig. 4-1). Note: For the IDH4 Series, this may
take up to 45 seconds when the transponder is initially powered up with no RF connection.

5. Click on the Language menu to select a desired language for the text information on the Web page.

The language choices are English (default), Spanish, Portuguese, French and German.
