HLP 4800, Version 1.0, Rev A
Chapter 2
Overview
The HLP 4800 is Harmonic’s new flexible platform for mounting broadband communications
equipment.
The HLP 4800 Platform is used with a number of plug-in modules, such as the PWRLink
TM
series of 1310 nm laser transmitters and the SUPRALink
TM
series of 1550 nm DWDM laser
transmitters and optical amplifier, as well as the HRM3811 receiver, the METROLink
TM
series
of 1550nm narrowcast DWDM transmitters, and optical switches.
The new HLP 4800 Platform is designed to meet the economic and technical requirements of
broadband service providers. The modular design of the product offers the user a number of
advantages, including:
The flexibility to add plug-in modules as industry requirements change, without the need
to replace equipment shelves, power supplies or status monitoring equipment.
The economic advantage of maintaining spare plug-in modules rather than entire
subsystems.
Reduced network downtime because of plug-in module replacements.

HLP 4800 Chassis
The HLP 4800 is a rack-mount platform, three rack units in height, designed to be fitted to a
19-inch EIA standard rack flange. It will accommodate ten of Harmonic’s standard 1.3 inch
wide plug-in modules, using appropriate carriers. A typical configuration would contain one
or two CPS 4800 power supply modules, one HNC4800 controller with display and keypad,
as well as other Harmonic modules.
Controlling and monitoring of the HLP 4800 and modules is accomplished by the following
means:
Local control and monitoring using the momentary push buttons and forty character
display on the front panel of the HNC 4800
Remote control and monitoring by means of license enabled WEB/SNMP RJ-45 Ethernet
interface on the rear of the HNC 4800.
The forty-character display on the platform front panel provides the following:
Name and slot position of each module contained within the Platform.
Network address setting.
Control and diagnostic menus for each module in the Platform.
