Alpha XP-EDH-A2 Transponder Field Installation Instructions
A grounded Surge Protector (Alpha P/N 162-028-10) or equivalent) is required for all installations.
Do not place the transponder on top of the power supply or the batteries.
Make all battery harness connections to the batteries and connect the interface cables to the power supply before connecting the cables to the
transponder.
First, verify the transponder bears the warning label as shown at right. This indicates the unit is an XP-EDH-A2,
and the jump and switch settings described in this instruction will work properly.
Verify the transponder's MAC address is loaded into the CMTS, and DOCSIS conguration le options should be
set. Detailed instructions for eld installation procedures are available in the XP-EDH-A2 Technical Manual
(Alpha P/N 745-838-B2) available at www.alpha.com.

Important!
Plug in the 13 pin
connector so the black
wire is in pin one (the top
pin) and two open pins
are left at the bottom for
tamper switch connection.
NOTE:
A chipset upgrade to the XM Inverter Module and/or USM Card may be required; contact Alpha for
more information.
Set the jumpers and calibrate the USM card before making cable connections and applying load.
1. Switch the battery breaker OFF.
2. Remove the Inverter Module from the power supply. See the power supply's technical manual for instructions.
3. Position jumpers and switches as shown below.
First, verify the transponder bears the warning label as shown at right. This indicates the unit is an XP-EDH-A2, and the
jump and switch settings described in this instruction will work properly.
NOTE:
The EDH-A2 calculates Output Voltage using AC Scaling as opposed
to the EDH-A which uses DC Scaling. This requires changes to the
USM card jumper settings and eliminates the need to calibrate the USM
potentiometer.

The downstream level (DS) into the transponder should be ± 15dBmV. However, for optimal performance, set the level as
close to 0 dBmV as possible
Verifying Installation and Network Connectivity
• Once the rmware initializes, the LED sequence is as follows:
1. POWER LED on; all other LEDs off
2. DS, US ashing intermittently
3. ONLINE LED ashing fast and slow until registration is complete
4. ONLINE LED on solid indicating IP address has been assigned
5. DS ickering as data are sent from transponder to Network Management System
• Once the AM MIBs have been set through the network using SNMP, the network connection can be remotely veried
by entering the IP address into a web browser and conrming the display of correct power supply measurements.
For additional product information, refer to the XP-EDH-A2 technical manual (P/N 745-838-B2).
