AlphaNet™DSM3 Series DOCSIS®Status Monitor
for XM2 & XM2-HP Series CableUPS
Installation and Quick Start Guide
The AlphaNet DSM3 Series (DSM3, DSM3x models) Embedded DOCSIS Communications Module allows monitoring of Alpha power supplies
through existing cable network infrastructure. Advanced networking services provide quick reporting and access to critical powering information.
DSM3 Series Communications Modules utilize Simple Network Management Protocol (SNMP) and standard Management Information Bases
(MIBs) to provide network status monitoring and diagnostics. A Web interface enables authorized personnel direct local and remote access to
advanced diagnostics using a common Web browser. No custom software or proprietary cables are required.
The Communications Modules can be installed and congured for operation in either the XM2 or XM2-HP Power Supply. The major features of
the DSM3x are shown below; the DSM3 is shown on the following page.

Service personnel must verify the Inverter Module battery breaker remains in the OFF position until
instructed to return unit to service.
For units in service, backup battery power will not be available during this procedure.
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 conguration le's docsDevNmAccessTable per RFC 4639 (IPv4) or through
the SNMPv3 Notication 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
communication module and power supply parameters. Refer to the DSM3 Series Technical Manual for details.
3. Conguring the Network: provisioning the DHCP Server with the communications module's MAC address and assigning
it a DOCSIS conguration le.
These steps can be performed independently of one another. However, conguring the network prior to eld installation will
allow the installation to be veried while personnel are still on-site. Performing eld installation before network conguration
might result in additional eld 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 three thumbscrews.
4. Grasp the handle on the top right side of the Inverter Module. Pull rmly to release the module from the inverter connector.
Gently slide the module assembly straight out until the Inverter Module ribbon cable connector is accessible. Open the
retaining clips to remove the the ribbon cable (see Fig.3 below).
CAUTION!

5. If the Inverter Module is already equipped with a Communication Module,
remove it by loosening the two Phillips captive screws (Fig. 5, item A).
The following steps apply to both new installations or removal/replacement
of existing transponders:
6. Connect the 18-pin jumper (Fig. 6) supplied with the transponder into the
header on the back of the DSM3 Series circuit board (Fig. 7).

Fig. 9, Inverter Moodule / Ribbon Cable Connection
9. Reinstall the Inverter Module and reconnect the ribbon cable (see
Fig. 9). Make front panel connections (tamper, temperature sensor,
battery sense, etc.).
10. Verify the recording of the cable modem MAC address (RF MAC)
from the front of the unit, and the reporting of the MAC address
for network provisioning.
Use of the incorrect jumper will cause damage to the
Transponder. Fig. 6 shows the correct 18-pin jumper.
CAUTION!
7. Line up the 18-pin jumper with the header on the Inverter Module and connect
the unit to the Inverter Module (Fig. 8).
8. Fasten the Transponder to the Inverter Module by tightening the two captive
screws. It is recommended the screws be tightened alternately, a few turns
at a time so the transponder aligns in parallel to the Inverter Module.

11. Make Battery Sense Wire Kit connections. See the battery diagrams that came with the sense wire kit or reference the
DSM3 Series Technical Manual (Alpha p/n 745-814-B8).
12. Connect the RF drop and make front panel connections as shown in Fig. 10 for the DSM3, or Fig. 11 for the DSM3x.
The DOCSIS specication for downstream power level is ± 15 dBmV. However, for optimal performance, set the level
as close to 0 dBmV as possible. RF attenuators or cable simulators may be required to obtain optimal downstream and
upstream RF levels.

Test Connection
With the DSM3 Series Transponder used in conjunction with the CableUPS, connectivity may be veried via the Smart Display
on the XM2-HP Power Supply. The connection may also be tested using a computer and a standard Ethernet cable. Connect the
computer to the Ethernet port on the transponder, launch an Internet browser (e.g. Internet Explorer) and enter 192.168.100.1
in the address eld. The General Conguration page shown below will appear and display connectivity, power levels and power
supply status information. The power supply parameters will populate on the bottom half of the General page. System Name,
System Location, System Contact and Common Logical ID may be edited on this page; when prompted for a User Name and
Password, use "Alpha" and "AlphaGet".

1. Plug the power supply into the AC outlet (if not already plugged in).
2. Switch battery breaker ON.
3. The DSM Series 3 Status LEDs will all blink in unison upon initial power up.
The RDY LED will then begin blinking steadily indicating normal processor
activity.
4. Verify the DS and REG LEDs are on solid. This veries the Communications
Module has registered an IP address on the network.
5. Verify the RF LED is solid Green, indicating Upstream and Downstream Power
is within the default specied range and the Upstream RF Power is below the
recommended +50 dBmV.
6. Verify no XM2 / XM2-HP alarms are active.
