1.0 Introduction 1.1 Overview Alpha’s EDH4 transponder provides the ability to manage network power through an existing cable modem infrastructure for a variety of power supplies. Please see your Alpha representative for a complete listing. This manual focuses on the power supplies listed below. HMS-Enabled Power Supplies: • XM2 with EDSM Interface Non-HMS Alpha Power Supplies: • AM with RPM interface • XM with USM interface • XM2 with USM2 or USM2.
1.0 Introduction, continued 1.2 Interfaces The EDH4 includes six status LEDs and a mix of analog and digital connections supporting multiple configurations. Front Back Fig. 1-2, The EDH4 Transponder Interfaces 1.
1.0 Introduction, continued 1.4 Powering the EDH4 Transponder Power the EDH4 transponder through one of the following transponder interfaces: • Battery Interface Connection (BAT A/B) • Battery Interface Connection (BAT C/D) • HMS interface port (HMS) • Auxiliary (generic) I/O (AUX I/O) In the event of multiple sources of power (e.g., batteries and HMS port), the highest voltage will source power to the transponder. Installation Notes: 1.
1.0 Introduction, continued Cable modem infrastructures are likely to have unique characteristics. Therefore it is strongly recommended one transponder be installed and tested for proper operation before deploying the entire system throughout your network. Installing the transponders and making them operational consists of the following steps, which are explained in detail in this manual. 1.
1.0 Introduction, continued 1.7 Network Information The following worksheet will aid you in gathering the network information you will need as you move through the deployment process.
1.0 Introduction, continued 1.9 Configuration File Choices, continued The following is a sample cable modem configuration file. Include only those OIDs that will provide the desired features and functionality. 3 Fig. 1-4, Sample Cable Modem Configuration File 14 745-419-B0-001 Rev.
2.0 Installation 2.1 Alpha XM Series 2 and EDSM Card (HMS-Enabled) The EDH4 transponder can be interfaced to power supplies that support the SCTE-HMS interface. In addition, the EDH4 transponder can receive battery string data through the HMS interface port and can measure battery strings directly. If battery data is present from both the HMS interface and the direct battery connection (EDH4 BAT A/B or BAT C/D), the EDH4 transponder uses the direct battery connection data.
2.0 Installation, continued 2.1 Alpha XM Series 2 and EDSM Card (HMS-Enabled), continued WARNING! Installation should be performed only by qualified service personnel. Installation Procedure: 1. Remove the EDH4 transponder and cabling hardware from its shipping package. 2. Turn off battery breaker on the XM2 Inverter Module. CAUTION! Turning off the battery breaker will disconnect the standby batteries; as a result service would be interrupted in the event of a utility outage.

4.0 Dual IP Configuration 4.1 Dual IP Applications Occasionally you may want to access both the HMS side and the DOCSIS side of the transponder using two separate IP addresses. The following sections provide the user with the information necessary for configuring the transponder for use in a Dual IP Configuration. Transponders are shipped from the factory configured for Single IP use.
4.0 Dual IP Configuration, continued 4.3 Assigning an IP Address to the Transponder The Dual IP transponder will obtain its IP address by utilizing Dynamic Host Configuration Protocol (DHCP). Also, as specified in the RFC2132 specification, the transponder will request subnet mask and router information. In addition, if the transponder is to be configured by using values in an HMS initialization file (typically named hmsinit.
4.0 Dual IP Configuration, continued 4.5 Server IP Types Two different server IP types can be set for the SCTE-HMS side of the transponder; Server and Trap Destinations. Parameter Purpose Status Value Server IP This is the IP address of the device that is hosting the SNMP software manager that interacts with the transponder. SNMP traps will be sent to this address. Optional Dotted decimal IP address (e.g., 192.168.1.23) Trap Server IP Setting the Server IP will direct traps to that IP address.
4.0 Dual IP Configuration, continued 4.7 Configuration File The following is a brief guideline on how to setup/write the hmsinit.ini configuration file. IMPORTANT! Verify the hmsinit.ini configuration file has been successfully created, installed and tested prior to deploying transponders into the system in quantity. Create a text file on the TFTP server named hmsinit.ini, (filename entirely in lower case). Add the appropriate HMS configuration data (dependent on desired features/functions), to the file.
4.0 Dual IP Configuration, continued IMPORTANT! Verify the cable modem configuration file has been successfully modified and tested prior to deploying transponders into the system in quantity. 4.8 Cable Modem Configuration File The appropriate SCTE-HMS data (dependent on desired features/functions) specified in the previous section (Configuration File Data), must be included when configuration data is added to the cable modem configuration file. These OIDs allow access to the HMS side of the transponder.
