AlphaNet™ DM3.0 Series DOCSIS® Status Monitor
DM3.0 Series Transponder Installation for XM3 Quick Start Guide
Overview
DM3.0 Series Transponder installation and setup is comprised of three basic steps:
1. Installation of the DM3.0 Series transponder into the power supply, making front panel connections and verifying
operation.
2. Setting Options: The DM3.0 Series Transponders are designed for out-of-the-box, “plug and play” operation.
Non-default settings such as SNMP trap destination addresses may be required for the Network Management
System (NMS). SNMP trap addresses can be set automatically via the DOCSIS configuration file’s
docsDevNmAccessTable per RFC 4639 (IPv4) or through the SNMPv3 Notification settings (IPv6), while DM3.0
Series proprietary options may be set through type 11 TLV entries. The SCTE-HMS MIBs may need to be
compiled into a MIB browser before it can be used to monitor or set transponder and power supply parameters.
Refer to the DM3.0 Series Technical Manual for details.
3.
Configuring the Network: provisioning the DHCP Server with the transponder’s MAC address and assigning it a
DOCSIS configuration file.
These steps can be performed independently of one another. However, configuring the network prior to field installation
will allow the installation to be verified while personnel are still on-site. Performing field installation before network
configuration might result in additional field service calls to correct mistakes.
Installation / Replacement Procedure
Before removing the Inverter Module, verify the power supply device address is correct.
The power supply device address must not be set to zero and no two power supplies monitored by a single DM3.0 Series
Transponder can have the same address. Power supplies must have 1, 2 ,3 ,4 or 5 as an address.
To verify the power supply’s address, go to the LCD display on the inverter module and enter the “PWR CNFG” menu.
Scroll to the “Device Address” menu item and verify the device address is set to something other than 0 (Zero).
Removing the Inverter Module:
1. Turn off the battery breaker.
2. Disconnect the battery input and temperature sensor cables from the Inverter Module, followed by the tamper, RF
and battery sense cables if a transponder is currently installed.
3. Loosen the thumbscrew on the XM3 Inverter Module and the thumbscrew on the transponder (if applicable).
4.
Grasp the handle on the bottom right side of the Inverter Module. Pull firmly to release the module from the
inverter connector. Gently slide the module assembly straight out until the Inverter Module is accessible.
For XM3 units in service, backup battery power will not be available during this procedure.
CAUTION!
Service personnel must verify the Inverter Module battery breaker remains in the OFF position
until instructed to return the unit to service.
CAUTION!
