  • Page 3: Safety And Regulatory Information

    Using the correct power supply Always use the Cambium Power over Ethernet injector unit (PoE power supply) or Powered Indoor Unit (PIDU Plus) to power the ODU. Failure to use the correct power supply could result in equipment damage and will invalidate the safety certification and may cause a safety hazard.
  • Page 4 Alternative DC supply If the PTP 250 is to be powered from a DC supply (either as the primary power source or as a backup to the AC supply), the DC supply must be input to the ODU via a PIDU (not a PoE power supply).
  • Page 5 Installers and users must meet all local regulatory requirements for radar detection. To meet these requirements, users must set the correct country code during commissioning of the the PTP 250. If this is not done, installers and users may be liable to civil and criminal penalties.
  • Page 6 2-5. Other variants of the PTP 250 are available for use in the rest of the world, but these variants are not supplied to the USA or Canada except under strict controls, when they are needed for export and deployment outside the USA or Canada.
  • Page 7 Chapter 5: Installation. Training The installer needs to have basic competence in radio and IP network installation. The specific requirements applicable to the PTP 250 should be gained by reading Chapter 5: Installation Chapter 6: Configuration and alignment and by performing sample set ups at base workshop before live deployments.

  • Page 59 PTP 250 User Guide Chapter 2: Planning considerations This chapter provides information to help the user to plan a PTP 250 link. The following topics are described in this chapter: • Regulatory planning on page describes how to plan PTP 250 links to conform to the regulatory restrictions that apply in the country of operation.

  • Page 60: Chapter 2: Planning Considerations

    Once the correct Country Code is set by the user on first login, the PTP 250 caculates these limits automatically. Many countries impose EIRP limits (Allowed EIRP) on products operating in the 5.4 GHz and 5.8 GHz bands.

  • Page 61: Conforming To The Limits

    Conforming to the limits When a new PTP 250 unit is first accessed via the web interface, the user is required to select the Country Code from a list. Generally, the PTP 250 firmware does not allow the unit to be configured to operate outside the regulatory limits that apply to the selected country.

  • Page 62: Available Spectrum

    For example, at 5.8 GHz in the UK and some other European countries, the RTTT band 5795 MHz to 5815 MHz is barred. With the appropriate configuration for a country in this region, the PTP 250 will not operate on channels within this band.

  • Page 63: Channel Width

    PTP 250 User Guide Regulatory planning Channel width Select the required channel width for the link (20 MHz or 40 MHz). The wider channel has the greater capacity. As narrower channel widths take up less spectrum and have a greater link budget, selecting a narrow channel width may be a better choice when operating in locations where the spectrum is very busy.
  • Page 64 Regulatory planning Chapter 2: Planning considerations To comply with FCC rules, the affected channels must be unselected during staging, before the units are allowed to radiate on site, as described in Step 1: Wireless configuration on page 6-22. phn-2510_004v000 (Feb 2013)
