2.5 Installation
2.5.1 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 SRU
• Dirty Connectors and ports
• Faulty Small Remote Unite (SRU) components
• RF source equipment issue
• External RF Interface problem such as antenna port
• Wrong or Improper Ethernet cable for POE input
The following guidelines are required when the Headend unit is installed on the 19” rack:
• 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.
2.5.1.1 General Safety Precautions
The following precautions apply to the SRU:
• 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 FHU and SRU
unless equipped with protection goggle. Invisible infrared radiation may be present at the front
panel of the RHU, FHU 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.)
• When the service antenna is connected to the SRU, SMA connector must be firmly tightened.
(Caution: Do NOT over tighten the connector.)
• The PoE Ethernet cable should be run with the maximum no more than 300 feet distance. It is
only for in-building use only.
