1.0 Introduction The AlphaNet™ Series Model XP-EDH-A2 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-A2 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-A2 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, continued 1.2 LED Indicators The front panel has four LEDs which 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.
2.0 Installation Before installing the XP-EDH-A2 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 Installation, continued 2.1 General Installation Information for Supported Power Supplies, continued 2.1.1 Transponder Placement • • • • 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. Route and tie-wrap the cables in an orderly manner.
2.0 Installation, continued 2.1 General Installation Information 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 Installation, continued 2.1 General Installation Information 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-A2 transponder. Each set of instructions include the interface card settings, a system diagram, and the output voltage calibration needed to successfully operate.
