1.0 Introduction The AlphaNet DSM Series Model XP-EDH-A External DOCSIS Transponder manages network powering through the existing cable modem infrastructure. A single transponder can monitor and manage one power supply and batteries. The transponder transmits data to a management system over the network’s existing infrastructure. Standard SNMP (Simple Network Management Protocol) provides access by any SNMP manager. Status Monitoring information is compatible with ANSI/SCTE HMS standards.
1.0 Introduction, continued 1.1 System Overview The XP-EDH-A is designed for use with the following standby power supplies: • • • • XM2 XM AM/AP ZTT, ZTT+ The transponder hardware is the same for all applications and harness kits are available for specific configurations. The XP-EDH-A receives data from a Universal Status Monitoring Card on XM/XM2 series power supplies, from the status monitor connector on Lectro ZTT power supplies, or from the RPM card on AM power supplies.
1.0 Introduction to the DOCSIS Transponder, continued 1.2 LED Indicators The XP-EDH-A contains a DOCSIS 1.1 cable modem. The front panel contains one RF connector and three multi-pin connectors. The four LEDs indicate the following: POWER: Indicates device has power OFF: No power. ON: Power on. (Battery harness connected to a battery string.). ONLINE: Indicates a two-way RF (radio frequency) connection. OFF: No communication.
2.0 Installation Before installing the XP-EDH-A into a power supply, review your system requirements and determine the number of cable assemblies you need to monitor your HFC standby power supplies.
2.0 Installing the Transponder, continued 2.1 General Installation for Supported Power Supplies, continued 2.1.1 Mounting the Transponder • • • • Place the transponder on the shelf inside the cabinet next to the power supply. Do not place the transponder on top of the power supply. Maintain access to the front of the transponder to ease the connection of the cables. Ensure the cabinet door can close without damaging the cables. If appropriate, tie-wrap the harness to the handles on the inverter drawer.
2.0 Installing the Transponder, continued 2.1 General Installation for Supported Power Supplies, continued 2.1.5 Connecting the Power Supply Interface and Measurement Cables • • • Connect the power supply interface and measurement cables to the power supply. Connections are dependent on the type of power supply configuration you are using. See the section specific to your configuration. It is important to be able to measure the site input line voltage. If you are not using a USM2.
2.0 Installing the Transponder, continued 2.1 General Installation for Supported Power Supplies, continued 2.1.9 Setting the DOCSIS Configuration File Options • • This step is performed at the network end of the installation. This file supplies the security and community string settings for the system, as well as the software upgrade parameters. Set the community strings, matching your DOCSIS cable modems. The following is an example: Sets Read-Write Community string.
3.0 Installation Instructions for Specific Power Supplies These are specific installation instructions for standby power supplies supported by the XP-EDH-A transponder. Each set of instructions include the interface card settings, a system diagram, and the output voltage calibration needed to successfully operate. NOTE: All settings and instructions specified here supercede information found in previous manuals. NOTE: When monitoring commercial line power, the XM2 (with the USM2.

3.0 Installation Instructions for Specific Power Supplies, continued 3.1 Alpha XM2 Series, continued 3.1.4 XM2 USM2 Output Voltage Calibration You must calibrate the scaled output voltage of the USM2 cards. To calibrate the output voltage, use a DC voltmeter and adjust the potentiometer located next to the white 15-pin connector of the USM2 cards. Determine if the power supply has a 60V or 90V nominal output.
3.0 Installation Instructions for Specific Power Supplies, continued 3.2 Alpha XM Series Power Supply NOTE: You may require a chipset upgrade for the USM and XM inverter drawer for proper operation with the XPEDH-A. Operating an XM series power supply with the XP-EDH-A with the wrong version chipset firmware may result in intermittent or incorrect operation of the power supply. Contact your Alpha representative for additional information. 1.

Refer to the Alpha USM Installation manual for more information. Determine if the power supply has a 60V or 90V nominal output.
3.3 Alpha AM/AP Series Power Supply 1. If commercial power is present at the site, and the power supply is currently powered by commercial AC line voltage, turn the battery breaker OFF on the power supply. 2. If not already installed, install the RPM card. Refer to the instructions that come with this assembly.
