Alpha Technologies

Overview to the eld installation instructions

The XP-EDH3 transponder provides the ability to manage network power through an existing cable modem
infrastructure, for a variety of power supplies as shown in this document.

These instructions provide information important to the successful installation, connection and operational verication of
the Alpha XP-EDH3 transponder in a variety of systems.

Save these instructons for future reference.

CAUTION!

Use a surge protector in the cabinet when the transformer is used to measure line voltage.
Do not place the transponder on top of the power supply or batteries.
Make all battery harness connections and connect the interface cable to the power supply before
connecting the cables to the transponder.

Before eld installation, the transponder's MAC address should be loaded into the CMTS, and DOCSIS conguration le
options should be set.

Connection Instructions for the Alpha AM, XM Series Power Supply

NOTE:

A chipset upgrade may be required; contact Alpha for more information.
Set the jumpers and calibrate the USM card before making connections and applying the load.

1. Switch Battery Breaker OFF prior to removing the Inverter Module for USM Card installation and conguration.

WARNING!

When installing Battery Sense Cable Kit (BSC) or AlphaGuard sense cable, do not connect the black
(negative) wire of the BSC to the negative post on Battery 1.

2. It is advisable to install the Battery or Aux pwr cables (providing power to the External DOCSIS unit) and waiting until
the RDY LED is ashing normally before installing the power supply interface kit. This will reduce the chances of the
power supply transferring to inverter due to a low signal reference on the test control pin.

Connection Instructions for the Alpha XM Series 2 Power Supply

WARNING!

The XM2 batteries are isolated from chassis ground by design. Any voltage potential difference between battery (-)
and chassis ground must be eliminated before installing the transponder to avoid potential transponder damage. To
accomplish this, attach a ground jumper between battery (-) and chassis ground before installing the transponder. Once
the transponder is installed the jumper may be removed if desired.

Switch Battery Breaker OFF prior to removing the Inverter Module for USM2/USM2.5 Card installation and conguration.

Verifying Installation and Network Connectivity (applies to all power supplies)

Method 1: Status LEDs

After the initial transponder power-up, network communication can be veried by the following behavior:

Rx LED on Solid, occasionally ickering off, indicating CMTS communication
Tx LED off, but will icker when transmitting data to CMTS

Method 2: Local Port using Craft Port Cable, Alpha P/N: 875-349-10

Connect laptop to ‘Local’ port and set terminal emulator software settings to:

19200 Baud; 8-N-1; No Flow Control
Type >STATUS for transponder IP Address
Type >PSDATA 1 for power supply measurements

Method 3: Remote via HTTP Web Page

Place IP Address into Internet Web Browser to verify remote HTTP communication

Method 4: Remote via SNMP (Simple Network Management Protocol)

Use SNMP MIB Browser software to query power supply’s input voltage. [OID: 1.3.6.1.4.1.5591.1.4.2.1.23.1]
A valid response veries remote SNMP communication.
