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.
1.0 Introduction to the DOCSIS® Transponder, continued 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 configuration.
1.0 Introduction to the DOCSIS® Transponder, continued 1.1 System Overview, continued Equipment monitored via the AlphaGuard™: The AlphaGuard performs electrical compensation for differences in individual batteries in the string. The unit can be configured to pass measurements from the battery string to a status monitoring device (EDSM card, DOCSIS transponder, etc.) via an interface cable.

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 traffic to pass between transponder and SNMP manager. • Install the transponder and any related equipment in the power supply. • Connect an RF drop.
2.0 Transponder Installation, continued 2.1 Provisioning the Transponder, continued 2.1.2 Transponder Configuration Many SNMP Management Applications require an SNMP Trap to be sent from the transponder for self-discovery and for alarm notifications. An SNMP Trap destination address can be specified to the IDH3 through the DOCSIS configuration files docsDevNmAccessTable (RFC 2669). 12 745-420-B0-001 Rev.
2.0 Transponder Installation, continued 2.2 Verifying Firmware Version and Device Address Before removing the Inverter Module (IM), verify the power supply firmware version and device address are correct. • IM firmware 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.
2.0 Transponder Installation, continued 2.3 Installing the Transponder Hardware, continued 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.
2.0 Transponder Installation, continued 2.4 RF Connection Connect the RF drop to the RF connector on the transponder. The drop must have a properly installed ground block in or on the power supply enclosure. Recommended forward RF level is 0 dBmV. RF Connection Ground Surge Protector (User Provided) RF Cable to Headend See Caution Below Fig. 2-3, RF Connection with Ground Block Alpha requires installing a grounded surge suppressor (Alpha P/N 162-028-10 or equivalent). 2.
3.0 Network/Element Management Software 3.1 Provisioning the SNMP Manager The following MIB (Management Information Base) files are required for the SNMP Manager to collect data from the transponders. These files can be found on the Society of Cable Telecommunications (SCTE) web site www.scte.org.
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 traffic is port 80, but can be configured to use other ports via the Tollgrade httpMgmt MIB. HTTP port configuration 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.
4.0 Using the Ethernet (Craft) Port, continued 4.1 IDH3 Web Interface, continued 4.1.1 System Overview, continued Depending on the network configuration 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 first web page using 192.168.100.1.
4.0 Using the Ethernet (Craft) Port, continued 4.1 IDH3 Web Interface, continued 4.1.1 System Overview, continued You’ll see another dialog box, and enter the values as they appear in the diagram below: Click on “OK” and try to connect to the transponder once again using 192.168.100.1 in your Web browser. 745-420-B0-001 Rev.
4.0 Using the Ethernet (Craft) Port, continued 4.1 IDH3 Web Interface, continued 4.1.1 System Overview, continued NOTE: The IDH3 web pages do not automatically refresh, so the user must manually reload each one to view the most current data. Configuring the sysName and sysLocation OIDs It is also possible to configure 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.
