Navini Networks, Inc. Ripwave Base Station I&C Guide
Part #40-00047-00 Rev D v1.0 209
February 28, 2003
Design
Cabinet penetrations should be designed, sized, and located to permit the easy entry of required
wiring and cabling into and out of the cabinet, and should be of sufficient size to permit the
insertion/removal of pre-terminated cables and wires, if utilized. Cabinet penetrations should
support site-specific installation requirements. For example, the RFS antenna coaxial cable type
and size will vary due to the combination of the height of the installed antenna and the horizontal
and vertical runs from the cabinet to the antenna support structure, as well the customer’s choice
of vendor for the coaxial cables.
Cabinets should be designed to prevent weakening of the cabinet structure due to close proximity
or excessive penetrations within a confined space. Reinforcement of the cabinet, or special
access ports, may be utilized by a cabinet manufacturer to mitigate or eliminate this as a concern.
Cabinets should maintain the bend radius of all wire and cables penetrating the cabinet within
acceptable tolerances. Obstructions within the cabinet, either singularly or in combination, may
be created as a result of internal placement of cabinet structural components, or installed
electrical, electronic, mechanical equipment. Cabinet design should minimize or eliminate
potential personnel hazards caused by cables and conduit exiting the cabinet.
Penetrations Required
Subject to other considerations defined in this document, the following penetrations may or may
not be utilized:
• AC Power (service entrance, convenience outlet(s), external lighting, etc.)
• DC Power (connection to battery compartment)
• Generator receptacle
• Grounding (electrical, antenna lightning arrestors, AC surge protection, Telco surge
protection)
• Network Transport (microwave, fiber, T1, Ethernet, etc..)
• Telco (POTS)
• Alarm
• Antenna (multiple - refer to Navini BTS requirements)
