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.
Note the following:
The types and quantities of each power supply type•
Number of individual batteries per site (if you plan to increase the number of batteries in the •
future, consider ordering additional battery harnesses)
Length of required battery harness (The standard 4 ft length battery harness is used in the typical •
power supply cabinet where one to three battery strings are mounted in the trays underneath the
power supply shelf. If necessary, a 20 ft battery harness is available)
The required type of interface cards (RPM, USM, USM2.5, etc.)•
Utility power available at the site, 110V or 220V.•
NOTE:
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.
2.1 General Installation Information for Supported Power Supplies
There are a few basic steps to follow to install the XP-EDH-A2 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:
Transponder Placement1.
Disconnecting the DC power2.
Confi guring the Interface Card3.
Wiring the battery harness4.
Connecting the power supply interface and measurement cables5.
Confi rming the RF drop6.
System confi guration steps are:
Provisioning Network Connectivity7.
Confi guring the MIBS8.
Setting the DOCSIS confi guration fi le options9.
Completing and Testing the installation:
10
Verifying the operation10.
Detailed information on each of these steps follows.
745-838-B2-001 Rev. A
2.0 Installation, continued
2.1 General Installation Information for Supported Power Supplies, continued
2.1.1 Transponder Placement
Place the transponder on the shelf inside the cabinet next to the power supply. •
Do not place the transponder on top of the power supply.
Maintain access to the front of the transponder to ease the connection of the •
cables.
Ensure the cabinet door can close without damaging the cables.•
Route and tie-wrap the cables in an orderly manner.•
NOTE:
Depending on the type of enclosure and the power supply you are using, it may be necessary to orient the
Service Power Inserter (SPI) vertically to provide space for the transponder. Re-torque the SPI to spec (130
in/lbs) if repositioning becomes necessary. This is important, as the output neutral is not tied to ground until
connected to the SPI /enclosure.
CAUTION!
Backup capability is suspended with the DC breaker in the OFF position.
2.1.2 Disconnecting the DC Power
Place the DC breaker in the OFF position.
2.1.3 Confi guring the Interface Card
Each power supply contains an interface card which provides the common
communication layer between the power supply and the transponder. The settings
needed for your power supply are located in Section 3.0, "Installation Instructions
for Specifi c Power Supplies".
2.1.4 Wiring the Battery Harness
CAUTION!
Incorrect connections may damage the equipment and invalidate the warranty. Double-check all connections.
Prior to connecting the cables to the transponder, make all harness connections •
to the batteries and interface connectors on the power supply. See the battery
diagrams for your specifi c power supply.
Double-check all connections. Incorrect connections may damage the •
transponder or the power supply. Correct connections at the batteries are
extremely important to the proper operation of the power supply.
Ensure that the high current carrying cables and jumpers (heavy gauge black •
and red cables) remain in direct contact to the battery terminals.
Never place the transponder battery harness lugs between the current carrying •
jumper/cable lugs and the battery terminals. See the power supply installation
manual for more information.
In some cases there are more battery harness leads than there are batteries. •
Connect all unused lugs to the same terminal as the V(-) lead, the same terminal
where the heavy gauge black cable from the inverter is connected. This prevents
stray voltages from being detected by the transponder.

2.0 Installation, continued
2.1 General Installation Information for Supported Power Supplies, continued
2.1.5 Connecting the Power Supply Interface and Measurement Cables
Connect the power supply interface and measurement cables to the power •
supply. Connections are dependent on the type of power supply confi guration
you are using. See the section specifi c to your confi guration.
It is important to be able to measure the site input line voltage. If you are •
not using a USM2.5/XM2 power supply, then it is recommended you use a
transformer (110V and 220V available*) to sample the commercial power at
the site. While it does not power the transponder, it makes it possible for the
transponder to report the actual line voltage. An additional transformer is not
necessary when using a USM2.5/XM2 power supply.
Use a surge protector within the cabinet when you are using a transformer to •
measure line voltage. Most cabinets come equipped with a duplex outlet.
* 110V applications: CBL-PS-PWR-01-001, p/n 875-563-10
220V applications: CBL-PS-PWR-03-002, p/n 875-562-10
(3' cord with IEC C13 connector and 220V US NEMA 6-15 plug)
2.1.6 Confi rming the RF Drop
An RF drop is required at the power supply site. The RF drop should not have •
plant voltage.
The transponder contains a DOCSIS 2.0 cable modem. The downstream level •
(DS) into the transponder should be between -15 and +15 dBmV, with a recommended level of 0dBmV.
2.1.7 Provisioning Network Connectivity
The transponder’s cable modem must be recognized by the CMTS as a valid device,
obtain an IP address from the DHCP server, locate the TFTP and TOD servers, and
communicate with the SNMP management server (trap receiver). Different security
methods are used to insure network integrity, some common issues are:
A “subscriber account” (where the subscriber is the transponder) may be required •
for each transponder.
The transponder’s MAC address may have to be pre-loaded into the CMTS.•
MAC fi ltering may have to be modifi ed to allow MAC addresses starting with •
00:03:08xx:xx:xx to be registered.
For SNMP access, UDP ports 161 & 162 must not be blocked.•
Firewalls must allow communication between the cable modem and the various •
servers noted above.
If the address of the TFTP and/or TOD server is different than the DHCP server, •
the response from the DHCP server must contain the TFTP and TOD addresses.
12
2.1.8 Confi guring MIBs
This step is not performed in the fi eld, but at the network end of the installation. •
There are two propriety MIBs (Management Information Base) from Networks •
needed to confi gure the XP-EDH-A2. Refer to Section 4.0, "Proprietary
Management Information Bases (MIBs)" for detailed information.
