Note Wireless radio cards are ESD sensitive, especially the RF switch and the power amplifier. To avoid damage by electrostatic discharge, the following installation procedure is recommended:
  • Touch your hands and the bag containing the radio card to a ground point on the router board (for example one of the mounting holes). This will equalize the potential of radio card and router board.
  • Install the radio card in the miniPCI socket.
  • Install the pigtail cable in the cutout of the enclosure. This will ground the pigtail to the enclosure.
  • Touch the I-PEX connector of the pigtail to the mounting hole (discharge), then plug onto the radio card.
  • Use external lightning protection for outdoor applications.
