3.2.2 Installation Location Requirements
• Mounting surface shall be capable of supporting the weight of the equipment.
• In order to avoid electromagnetic interference, a proper mounting location must be selected to minimize interference from
electromagnetic sources such as large electrical equipment.
• Working space available for installation and maintenance for each mounting arrangement.
• Ensure unrestricted airflow.
• Ensure grounding connector is within reach of the ground wire.
• Ensure a power source is within reach of the power cord and the power source has sufficient capacity.
• Where appropriate, ensure unused RF connectors are terminated.
• Do not locate the equipment near large transformers or motors that may cause electromagnetic interference.
• Reduce signal loss in feeder cable by minimizing the length and number of RF connections.
• Ensure the equipment will be operated within the stated environment (refer to Appendix A: Specifications or unit datasheet).
• Where appropriate, confirm available of suitably terminated grade of RF and optical fiber.
• Observe handling of all cables to prevent damage.
3.2.3 Safety Guidelines
Before installing the equipment review the following safety information:
• Follow all local safety regulations when installing the equipment.
• Only qualified personnel are authorized to install and maintain the Repeater.
• Ground specified equipment with the provided grounding bolt
• Do not use the grounding bolt to connect external devices.
• Follow Electro-Static Discharge (ESD) precautions.
• Use low loss cables to connect the antennas
3.2.4 Rack Safety and Installation Guidelines
3.2.4.1 Rack Safety Instructions
The following guidelines are relevant to the rack installed units. Review the following guidelines to help ensure your safety and
protect the equipment from damage during the installation.
• Only trained and qualified personnel should be allowed to install or replace this equipment.
• Verify that ambient temperature of the environment does not exceed 50°C (122° F)
• To maintain a low center of gravity, ensure that heavier equipment is installed near the bottom of the rack and load the rack
from the bottom to the top.
• Ensure that adequate airflow and ventilation within the rack and around the installed components so that the safety of the
equipment is not compromised. It is recommended to allow for at least about 2 cm of airspace between devices in the rack.
• Verify that the equipment is grounded as required – especially the supply connections.
3.2.4.2 Rack Installation Guidelines
• To maintain a low center of gravity, ensure that heavier equipment is installed near the bottom of the rack and load the rack
from the bottom to the top.
• Verify that the rack height can support the unit to be installed, where you may also want to consider future installations.
− IHU rack height = 4U
− PSU6 rack height =1U
− MRU rack height = 6U
3.2.5 Power Safety and Power Requirements
