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 configuration file options should be
set. Detailed instructions for field installation procedures are available in the XP-EDH-A2 Technical Manual
(Alpha P/N 745-838-B2) available at www.alpha.com.
