Alpha DSM3 for XM3 Quick Start Guide

AlphaNet™ DSM3 Series DOCSIS® Status Monitor

for the XM3 CableUPS

®

Installation and Quick Start Guide

The AlphaNet DSM3 Series (DSM3, DSM3x, DPM 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 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 proprietary cables or software are required.

The Communications Modules can be installed and congured for operation in the XM3-HP CableUPS® Power Supply. The major features of

the DSM3x are shown below; the DSM3 and the DPM models are shown on the following pages.

Overview

CAUTION!

For units in service, backup battery power will not be available during this procedure.

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

transponder and power supply parameters. Refer to the DSM3 Series Technical Manual for details.

3. Conguring the Network: provisioning the DHCP Server with the transponder’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.

Installation Procedure

Removing the Inverter Module:

1. Turn off the battery breaker.

CAUTION!

Service personnel must verify the Inverter Module battery breaker remains in the OFF position until instructed to
return unit to service.

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 rmly to release the module from the inverter

connector. Gently slide the module assembly straight out until the Inverter Module is accessible.

Installation Procedure, continued

The following steps apply to both new installations or
removal/replacement of existing Communications Modules:

5. Line up the 18-pin connector on the Communications Module
(Fig. 5) with the 18-pin socket on the Inverter Module and connect
the two units together (Fig. 6).

6. Fasten the Communications Module to the Inverter Module
by tightening the two captive screws. (Fig. 4, items A) It is
recommended the screws be tightened alternately, a few turns
at a time so the Communications Module aligns in parallel to the
Inverter Module.

Module to the Inverter Module

7. Reinstall the Inverter Module, tighten the two thumbscrews and
reconnect the front panel connections (tamper, temperature sensor,
battery harness, etc.).

8. Verify the recording of the cable modem MAC address (RF MAC) from the

front of the unit for network provisioning.

Installation Procedure, continued

9. Make Battery Sense Wire Kit connections (not required with Smart AlphaGuard). Refer to the battery diagrams provided
with the sense wire kit or reference the DSM3 Series Technical Manual (Alpha p/n 745-814-B11).

10. Connect the RF drop and make front panel connections as shown in Fig. 8 for the DSM3, or Fig. 9 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.

Initial Turn-up and Test / Returning the Unit to Service

1. Plug the power supply into the AC outlet.

2. Switch battery breaker ON.

3. The DSM3 Series 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

LED Color Rx Range (dBmV) Tx Range dBmV)

Green +10 to -10 0 to +50

Blue +15 to +10 and -10 to -15 +50 to +55

Red >+15 and <-15 >+55

Table 1, RF Power Default Values

recommended +50 dBmV (Table 1).

6. Verify no XM3 alarms are active.

Test Connection

1. XM3 Smart Display - COMM Menu:

Verify DSM3 communication parameters such as IP address, RF Power

Levels and Signal/Noise Ratio on the COMM menu of the XM3 Smart
Display. Press Enter <ENTR> to open the COMM-GENERAL Menu

enabling the operator to view values for communications parameters.
Pressing the up or down arrow softkeys will show two lines of information
for each submenu item (Fig. 10).

2. Local Web Server Access:

You may also test the connection 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 such as alarms, output voltage, output current and individual battery voltages. 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".

3. Remote Web Server Access:

Connect the computer to the cable modem network, launch an Internet browser (e.g. Internet Explorer) and enter the

designated transponder IP address in the address eld. The General Conguration page will appear (Fig. 11).
