    (Contact your Account Manager for further details). No matter which are chosen, all cables and connectors must meet FCC or other regulatory limits for RF, UL, and NEC/CEC. Selection guidelines are provided by Cisco based upon the frequency band and the length of the cable required between the BS and BWX 8305 Basestation antenna.

  • Page 34: Confirm Mounting Rack Or Outdoor Enclosure Availability

    5.13 Confirm Mounting Rack or Outdoor Enclosure Availability Reference: Appendix F, “BWX 8305 Basestation Outdoor Enclosure Manufacturers” If the BS will be housed inside a building, it is typically mounted in a standard 19- or 23-inch rack. Rack adapters are needed to mount the equipment in a standard 23-inch rack. If the BS will be housed outdoors, the Service Provider must select and make ready an outdoor enclosure.

  • Page 35: Grounding Requirements

    BS can generate intense electrical currents traveling over the power and/or backhaul lines and into the BS equipment, damaging it. For this reason, Cisco strongly recommends adding the primary surge protection as well as surge protection devices at the power and backhaul demarcation points.
