1.2 Description
The HRR 4104 is a high-performance optical return path receiver that is
optimized to operate in the 5 to 100 MHz return band. This compact (half-slot)
plug-in module is designed for use in the Harmonic HLP 4200 equipment
platform. An HMC 4008 module carrier is needed and mounts two HRR 4104
modules in the platform.
The HRR 4104 is a quad receiver card. The four receivers are designed to
operate independently, or can be configured as four redundant pairs with
another HRR 4104 module.
The HRR 4104 has the following key features:
• Very high packing density
• High RF output level
• Many configuration options
• Automatic or manual gain control to compensate for variations in optical
input
• Local control of operating parameters—provided by the HLP 4200
Platform
• Remote control and monitoring—provided by the NET 5200 NETWatch™
Site Controller

Receiver. Please read all the instructions before beginning installation.
This chapter describes:
• How to receive and inspect the HRR 4104
• Tools and accessories
• How to install the HRR 4104 module into an HLP 4200 Platform
• How to configure two HRR 4104 modules as a redundant pair
• How to connect the RF output cables
• How to install and use the HFM 4000 Fiber Management Tray (optional)
• How to connect the input fiber cables
• How to test RF signal output
2.1 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 Appendix B, Harmonic Inc. – Offices , for contact information.
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.
2.2 Tools and Accessories
The following accessories are provided with each HRR 4104:
• Antistatic bag
The following accessories are provided with each HMC 4008:
• 6-pin muting cable assembly (part no. 229-0020316)—for primary/backup
connection

The following optional accessories are not included:
• Four 4 dB couplers—to combine the RF outputs from two HRR 4104
modules in a redundant configuration
• HFM 4000 Fiber Management Tray (see Section 2.6)
• Four #10 screws with 10-24 UNC thread, and Phillips screwdriver—
to mount the HFM 4000 in the rack
2.3 Installing the HRR 4104
The HRR 4104 receiver module plugs into an HMC 4008 module carrier,
shown in Figure 2-1. Each HMC 4008 carrier can accommodate two half-slot
HRR 4104 modules. The receiver module is held in the carrier by blind mate
RF connectors on the carrier. You can place the HMC 4008 carrier into any
available position in the HLP 4200 Platform.
Figure 2-1. HMC 4008 module carrier, front and rear panel features
To provide leverage for the blind mate connections, install the HMC 4008
carrier into the HLP 4200 Platform before you install the HRR 4104 module
into the carrier. The HLP 4200 Platform can be powered and operating during
the installation process.
