Federal Communications Commission (FCC) rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment.
This equipment generates, uses, and can radiate radio frequency energy. It may cause harmful interference to radio communications
if it is not installed and used in accordance with the instructions in this manual. Operation of this equipment in a residential area is
likely to cause harmful interference. If this occurs, the user will be required to correct the interference at his or her own expense.
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not
cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Connections between the Harmonic equipment and other equipment must be made in a manner that is consistent with maintaining

When you work with this equipment, take the following precautions:
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation
exposure.
Never look at an optical fiber using a direct magnification fiber scope without verifying that all lightwave sources on the fiber are
turned off.
Never look directly into an optical connector.
Install protective covers or caps over connectors when they are not being used.
Always assume that exposed optical connectors and cables are energized.

Lorsque vous travaillez avec ce matériel, prenez les précautions suivantes:
L’utilisation de commandes ou de réglages ou l’utilisation de procédures autres que celles décrites dans ce manuel d’utilisation
peut générer une exposition á des radiations dangeureuses.
Ne jamais regarder une fibre optique directement avec un outil d’inspection de fibres sans verifier que toutes les sources
lumineuses dans la fibres sont éteintes.
Ne jamais regarder directement á un connecteur de fibre optique.
Installer les bouchons protecteurs sur les connecteurs qui ne sont pas utilisés.
Toujours supposer qu’un connecteur éxposé ou une fibre optique émettent de l’énergie lumineuse.
Toujours mesurer la puissance optique d’une fibre optique ou d’un connecteur avant de le nettoyer une inspection visuelle pour
s’assurer que la fibre n’émet pas d’énergie lumineuse.
Beim Arbeiten mit diesem Gerät, beachten Sie die folgenden Vorsichtsmaßnahmen:
Die Verwendung von Reglern oder Einstellungen sowie die Durchführung von Verfahren die hier nicht beschrieben sind kann dazu
führen das Sie gefährlicher Strahlung ausgesetzt werden.

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 PWRLinkTM
series of 1310 nm laser transmitters and the SUPRALinkTM series of 1550 nm DWDM laser
transmitters and optical amplifier, as well as the HRM3811 receiver, the METROLinkTM 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.
2.1 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.

Chapter 3
Installing the HLP 4800 Platform
This chapter provides the information necessary to install the HLP 4800. Please read all
instructions before beginning installation.
This chapter describes:
How to receive and inspect the HLP 4800
How to mount the HLP 4800 platform
To install the HNC 4800 controller see the HNC 4800 User’s Guide.
To install and power the CPS4800 power supply see the CPS 4800 User’s Guide.
After you have successfully installed the HNC 4800 controller and the CPS 4800 power
supply, you can access the user interfaces, as described in the HNC 4800 User’s Guide.
CAUTION: To protect yourself from potential injury and to protect the equipment from further damage,
do not perform any operational tests if the equipment appears to be damaged.
CAUTION: Before removing equipment from its antistatic bag, touch a ground point for several
seconds. A suitable ground point is an unpainted part of the chassis of a grounded piece of equipment.
3.1 Tools and Accessories
The following tools are necessary for installation, and are not included with the HLP 4800:
#2 Phillips-head screwdriver
#1 flat-bladed screwdriver
3.2 Receiving and Inspecting
As you unpack your unit, inspect the shipping container and equipment for damage. Save the
shipping material for future use. If the container or the equipment is damaged, notify both the
freight carrier and Harmonic. See Maintenance and Troubleshooting on page 17 for contact
information.
3.3 Mounting the Unit in the Rack
The HLP 4800 occupies three rack-unit spaces in an EIA standard 19-inch rack. Follow these
steps to mount the unit in the rack:
1. Mark the exact position in the rack where you want to install the unit.
2. Prepare the four mounting screws and #2 Phillips screwdriver.
3. Use four mounting screws to attach the mounting brackets on the HLP 4800 rack ears to
the rack.

Chapter 3 Installing the HLP 4800 Platform Power Requirements

3.3.1 Connecting the Grounding Lugs
Connect the ground contact to ground. This is important for your safety. The ground contact
is located on the rear panel, which is shown in Figure 2-2 on page 13. the thread is 10-32
UNC.
3.4 Power Requirements
The HLP 4800 accepts CPS 4800 power supply modules that generate 24 VDC for the
internal bus. For standard 100-240 VAC, 50/60 Hz input the CPS 4800-AC module is used.
For standard -48VDC input the CPS 4800-DC module is used.
To install the CPS4800 see the CPS 4800 Users Guide.
3.4.1 Connecting an External 24 VDC Power Source
The unit can have backup power by an external 24 VDC source. This input is only protected
by an internal fuse, and it is your responsibility to keep this voltage below + 28 V and have
surge and spike protection. If you do not, the plug-in units may be damaged.
Connect the external 24 VDC power source to the terminal block connector located on the
rear of the HLP 4800 according to Figure 2-2: Rear panel, HLP 4800 on page 13. Switch the
external supply off prior to making the connection and observe the correct polarity. Use
number 14 AWG wire. Refer to Figure 3-1: +24V backup terminal block Harmonic Part
Number 406-0000556 on page 15.
Figure 3-1: +24V backup terminal block Harmonic Part Number 406-0000556
DANGER: To avoid personal injury and equipment damage, switch off the power from the DC source
before installing. Never handle live wiring.
3.5 Connecting the Alarm Relay
External alarm equipment can be connected to the HLP 4800. The HLP 4800 has a 5-pin
alarm relay located on the rear panel, as shown in Figure 2-2: Rear panel, HLP 4800 on
page 13.

5 are closed.
When an alarm occurs, Pin1 and Pin 2 make electrical contact, while Pin 3 and Pin 5 are left
open. This remains until the alarm condition is removed.
