2.0 Installation
Before installing the XP-EDH-A2 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-A2 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.
