1.0 Introduction to the DOCSIS® Transponder
The IDH3 Transponder for the XM2 power supply manages network powering through existing cable
modem or high speed data infrastructure. A single transponder can monitor and manage multiple
power supplies, multiple strings of batteries, and one generator. The transponder transmits data
to a management system via the existing DOCSIS network. SNMP (Simple Network Management
Protocol) keeps bandwidth use to a minimum. Status monitoring data is compatible with ANSI/SCTE
HMS (Hybrid Management Sublayer) standards.
With optional VoIP test functionality, the power supply transponder becomes a powerful network
diagnostics tool. Contact Alpha Technologies for more information.
Outstanding Features:
• Uses existing headend DOCSIS CMTS equipment.
• Uses ANSI/SCTE HMS standards.
• Single transponder supports up to six power supplies, two battery strings, and one generator.

1.1 System Overview
The IDH3 Transponder obtains data from the EDSM (Enhanced Digital Status Monitoring)
interface card through an XM2 Power Supply. The EDSM collects data directly from the
battery strings or from the AlphaBus Communications Network, depending on system
confi guration.
Equipment monitored (direct battery monitoring):
• An XM2 Power Supply
• One or two 36Vdc or 48Vdc battery strings
• One AlphaGen stationary generator system (if installed)

2.0 Transponder Installation
Steps to a Successful Installation:
• Operator’s IT Department must allow the transponder’s Cable Modem (CM) to obtain an IP
address from the DHCP Server.
• Operator’s IT Department must provision the transponder, as described in the following section.
• Operator’s network security policies must allow SNMP traffi c to pass between transponder and
SNMP manager.
• Install the transponder and any related equipment in the power supply.
• Connect an RF drop.
• Verify proper operation.
2.1 Provisioning the Transponders in the Network
Before installing transponders, the transponders must be provisioned in the network for the
network to recognize, discover, and communicate with them when they are powered up. The
following graphic shows a typical network.
2.1.1 Network Connectivity
NOTE:
Some provisioning systems require that the transponder’s MAC address be added to the provisioning server
prior to installing the transponder to achieve full functionality.

2.1.2 Transponder Confi guration
Many SNMP Management Applications require an SNMP Trap to be sent from the
transponder for self-discovery and for alarm notifi cations. An SNMP Trap destination
address can be specifi ed to the IDH3 through the DOCSIS confi guration fi les
docsDevNmAccessTable (RFC 2669).

2.2 Verifying Firmware Version and Device Address
Before removing the Inverter Module (IM), verify the power supply fi rmware version and
device address are correct.
• IM fi rmware v3.00.0 is the minimum version compatible with the DOCSIS Embedded
Transponder.
• The power supply device address must not be set to zero, and no two power supplies
monitored by a single transponder may have the same address.
1. Press the Enter key on the inverter module twice to access the SETUP Menu.
2. Press the Down key until CODE VER is displayed.
3. Verify that the fi rmware code is 3.00.0 or higher.
4. Press the Down key twice until DEVICE ADDRESS is displayed.
5. If the address is correct (and not zero), skip to Step 10.
6. To change the address, press the Enter key to enter the Edit mode.
7. Press the Up or Down key until the desired address (between 1 and 7) is displayed.
Remember that each power supply on a single transponder must have a unique address.
8. Press the Enter key to load the new address.
9. Press the Enter key again to accept the new data.
10. Press ESC three times to return to the OPERATION NORMAL screen.
2.3 Installing the Transponder Hardware
The Embedded Transponder is static sensitive. An ESD wrist strap should be worn when installing
the transponder.
Tools Required: #1 Phillips Screwdriver
1. Move the XM2 Battery Breaker to the OFF position.
2. Unplug all connections to the front of the Inverter Module (battery cable, RTS, etc).
3. Loosen the thumbscrews holding the Inverter Module into the power supply. Slide the
Inverter Module out just enough to disconnect the ribbon cable. Now slide the Inverter
Module out of the power supply.
To reduce the risk of electric shock, completely remove the Inverter Module from the Power
Supply prior to installation.

4. Attach the new transponder ribbon cable supplied to the 10-pin connector on the
transponder. The connectors are keyed to prevent incorrect orientation.
5. Attach the plastic standoff to the transponder PC board as shown in Fig 2-1
6. Verify that the MAC address label is installed on the transponder. If the label is missing,
locate the label in the packaging and apply to the transponder as shown in Fig 2-2.
7. Place the transponder as shown in Fig 2-2 below. The RF connector must be inserted
through the front of the Comm Module bracket.
8. Press the standoff into the Inverter Module chassis.
9. Secure the transponder to the Comm Module Bracket with the two screws provided.
10. Connect the transponder ribbon cable to the EDSM. Note the 90o twist in the cable.
11. Reconnect the Inverter Module ribbon cable, and reinstall the Inverter Module into the
power supply.
12. Reconnect all the cables unplugged in Step 2 .
13. Move the Battery Breaker to the ON position.

4.0 Using the Ethernet (Craft) Port
4.1 IDH3 Web Interface
4.1.1 Overview
A web interface is available on the IDH3 transponder. The default port for HTTP
traffi c is port 80, but can be confi gured to use other ports via the Tollgrade httpMgmt
MIB. HTTP port confi guration is available for the cable modem interface (via the
cable modem IP address) and the CPE interface (via the Local connection). The
Local connection’s IP address is 192.168.100.1, and may be easily accessed by
using a standard CAT5 patch cord between a computer and the ETHERNET port on
the front of the transponder.
The interface can be accessed by typing the cable modem IP address of the
transponder into your web browser. The interface includes status data for the cable
modem, the HMS transponder, High Speed Internet Access (HSIA) diagnostics, the
RF constellation page and equalizer page, and the MTA (Media Terminal Adapter) in
VoIP systems.

Depending on the network confi guration of the computer you are using to connect to
the IDH3 transponder, it may be necessary to set the network interface to a temporary static IP address. This will make itself known if you can’t bring up the fi rst web
page using 192.168.100.1. Here’s how to resolve that issue, and connect to the
transponder:
Click on the “start” button (lower left button on most Windows computers). When
the window pops up, right-click on “Network” (usually about half the way down the
second column).
Click on the bottom option, “Properties,” and right-click on the network interface you
are using. You’ll see a dialog box much like the one below; scroll down to the entry
“Internet Protocol (TCP/IP)” and then click on “Properties.”

NOTE:
The IDH3 web pages do not automatically refresh, so the user must manually reload each one to view the
most current data.
Confi guring the sysName and sysLocation OIDs
It is also possible to confi gure the sysName (1.3.6.1.2.1.1.5.0) and sysLocation
(1.3.6.1.2.1.1.6.0) OIDs from the web interface. This feature is password protected.
There are both Admin and User usernames and passwords. Both usernames (Admin
and User) have the authority to set sysName and sysLocation. The passwords can
be changed via the Broadcom httpMgmt MIB. The specifi c OIDs and default values
are shown below.
Table 5. OIDs for Usernames and Passwords for Web Interface Access
It is possible to change the port number for Web Access and to disable it entirely.
The table below lists the Parameters, OIDs, and default settings. Setting the Port
value to sero (0) will disable access to the HTTP server for the given interface. The
specifi c OIDs and their default values are listen in Table 6. The port must be open to
use all of the deatures described in the following sections.
