7-4 InterReach Fusion Installation, Operation, and Reference Manual
CONFIDENTIAL D-620610-0-20 Rev F
3. The internal power supplies have internal fuses that are not user replaceable. Con-
sider the worst-case power consumption shown on the product labels when provi-
sioning the equipment’s AC power source and distribution.
4. Verify that the Hub is grounded properly using the AC power cord third wire
ground.
NOTE: Be careful with the mechanical loading of the rack mounted hub.
Mount the equipment in the rack in such a way that a hazardous condition,
due to uneven mechanical loading, does not result.
7.2.2 General Safety Precautions
The following precautions apply to TE products:
• The units have no user-serviceable parts. Faulty or failed units are fully replaceable
through TE. Please contact us at:

• When you connect the fiber optic cable, clean all optical fiber SC/APC connectors
according to the cable manufacturer’s instructions.
• When you connect a radiating antenna to an RAU, firmly hand-tighten the N con-
nector – DO NOT over-tighten the connector.
WARNING: To reduce the risk of fire or electric shock, do not
expose this equipment to rain or moisture. The components are
intended for indoor use only. Do not install the RAU outdoors. Do not
connect an RAU to an antenna that is located outdoors where it could
be subject to lightning strikes, power crosses, or wind.
• The Expansion Hub and RAU units are designed for intra-building cabling only.
Outdoor routing of any cabling to these units shall not exceed 140 feet.
NOTE: Outdoor cables farther than 140 feet must be installed with proper
lightning protection.
7.2.3 Fiber Port Safety Precautions
The following are suggested safety precautions for working with fiber ports. For
information about system compliance with safety standards, refer to Appendix B.
