3 Installation

3.1 Installation Requirements

Before and during installation, the following should be carefully verified in order to avoid any

problem:

 Faulty Cabling/Connectors: Fiber cable and connectors must be verified prior to plugging

into the RHU

 Dirty Connectors and ports

 Faulty Radio Hub Unit (RHU) components

 RF source equipment issue

 External RF Interface problem such as antenna port

The following guidelines are required when the RHU is installed on the 19” rack of Headend room:

 Locate the equipment with the space for the sufficient airflow to prevent build-up from

the overheating. Do not compromise the amount of airflow required for safe operation of

the equipment.

 Verify the power connection and Fiber cables prior to turning on the systems.

WARNING: Equipment loading must be verified prior to mounting the equipment on the wall or 19”

rack.

3.1.1 General Safety Precautions

The following precautions apply to the RHU:

 The units have no user-serviceable parts. Faulty or failed units are fully replaceable through

Intelibs.

 When the Fiber cable is connected to the equipment, the connectors must be free from the dust

and connected according to the cable manufacturer’s instructions. (WARNING: For the safety,

DO NOT conduct eye-contact at the connector ends of the fibers or the port of the RHU and SRU

unless equipped with protection goggle. Invisible infrared radiation may be present at the front

panel of the RHU and SRU. Do not remove the fiber port dust caps unless the port is going to be

used. Do not stare directly into a fiber port.)
