Service personnel must verify the Inverter Module battery breaker remains in the OFF position until instructed to
return unit to service.
CAUTION!
For units in service, backup battery power will not be available during this procedure.
CAUTION!
Overview
DSM3 Series installation and setup is comprised of three basic steps:
1. Installation of the DSM3 Series into the power supply, making front panel connections and verifying operation.
2. Setting Options: the DSM3 Series is 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 DSM3 Series proprietary options may be set through type 11 TLV entries.
The SCTE-HMS and Alpha 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 DSM3 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.
Removing the Inverter Module:
1. Turn off the battery breaker.
Installation Procedure
2. Disconnect the battery input and temperature sensor cables from the Inverter Module and the tamper, RF and battery
sense cables from the communication module if one is currently installed.
3. Loosen the two thumbscrews on the XM3 Inverter Module.
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.
