2.0 Installation
Before installing the XP-EDH-A into a power supply, review your system requirements and determine
the number of cable assemblies you need to monitor your HFC standby power supplies.
The procedure for installing the XP-EDH-A into any supported power supply involves general information,
(information that is common to all the power supplies), and information specifi c to an individual type of power
supply. These installation instructions are divided into two sections to refl ect this. It is recommended that you
read through the general instructions and then take note of any information specifi c to your power supply.
Also, installation of this product involves both fi eld installation and the confi guration of the system, including
network security, SNMP set-up, and other system provisioning. While those two procedures are handled
independently, they are presented together in the section specifi c to your power supply.
2.1 General Installation Information for Supported Power Supplies
NOTE:
There are a few basic steps to follow to install the XP-EDH-A into supported power supply
sites. The steps are either fi eld steps or system confi guration steps, and can be performed
independently.
Field installation steps are:
Mounting the transponder
Disconnecting the DC power
Wiring the battery harness
Connecting the power supply interface cables
Confi rming the RF drop
System confi guration steps are:
