Safety Notes Review the drawings and illustrations contained in this manual before proceeding. If there are any questions regarding the safe installation or operation of the system, contact Alpha Technologies or the nearest Alpha representative. Save this document for future reference. To reduce the risk of injury or death and to ensure the continued safe operation of this product, the following symbols have been placed throughout this manual. Where these symbols appear, use extra care and attention.
1.0 Introduction to the DOCSIS Transponder The DOCSIS Digital Embedded 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 DOCSIS Digital 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 AlphaGuard): • A primary XM2 Power Supply (via an internal network connection). • Up to five additional XM2 Power Supplies equipped with Serial Interface (SI) cards.
1.0 Introduction to the DOCSIS Transponder, continued 1.2 LED Indicators HMS: Indicates status of serial communications between transponder and EDSM OFF: OFF flickering ON: No communications Communicating with EDSM RDY: Indicates status of transponder OFF: ON: Flashing ON & OFF: RX: Indicates status of link with CMTS OFF: ON flickering OFF: OFF flickering ON: Flashing ON & OFF: TX: 10 No power to transponder from EDSM, or malfunctioning transponder.
2.0 Transponder Installation Steps to a Successful Installation: • Operator’s IT Department must allow the transponders’ Cable Modem (CM) to obtain an IP address from the DHCP Server. • Operator’s IT Department must load the HMSINIT.ini file on the TFTP Server. • 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. • Verify proper operation. 2.
2.0 Transponder Installation, continued 2.1 Provisioning the Transponder, continued 2.1.2 Transponder Configuration File The transponder’s CM, at first power-up or reset command, requests a configuration file from the TFTP server. The file must contain the IP address of the SNMP manager. It may also contain up to five additional SNMP trap recipients. The SNMP manager will be the only device that can perform SNMP set/get/get-next commands.
2.0 Transponder Installation, continued 2.2 Verifying Software Version and Device Address Before removing the Inverter Module (IM), verify the power supply software 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 as shown in Fig. 2-1. The connectors are keyed to prevent incorrect orientation. 5. Attach the plastic standoff to the transponder PC board as shown in Fig 2-2. 6. Verify that the MAC address label is installed on the transponder.
2.0 Transponder Installation, continued 2.4 RF Connection Connect the RF drop to the face of 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. Battery Breaker LOCAL Battery Input RF Temp Probe Ground Surge Protector RF Cable to Headend RF Connection User Provided See Caution Below Fig.
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 Local Port The local port allows the technician to communicate with the transponder and power supply through a PC’s RS-232C serial port. 1. Connect the optional Local Port to RS-232C Adaptor Cable (Alpha P/N 875-349-10) between the transponder’s Local Port and the computer’s serial port. Launch the computer’s Terminal Emulation Software (HyperTerminal is recommended).
4.0 Local Port, continued Enter a command, and press ENTER. If there is more than one power supply connected to the transponder, then PSDATA and PSTEST must be followed by the device address number. Verify communications between the power supply, EDSM and transponder with the PSDATA command. The data returned should match the data of the power supply display. MAC Address: 00-10-3F-00-00-0D Serial No: 123450000 Version: 1.0.2.L 1600 950-0315 A 05.00 IP Address: 192.168.1.
