    Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual • Connect a fixed (or a series of fixed) 50-ohm attenuator(s) to the RF connector, either directly or at the end of an RF transmission line. The attenuator should be at least 20dB as specified at 2400 MHz, and rated for a minimum of 1W input power.

    Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual can be significant. In some cases, there can also be a risk to human life by not protecting against lightning entering a building through wiring or improper grounding. If you do not have experience in this type of installation practice, it is strongly suggested that a qualified electrician and/or telecoms professional is consulted during the installation of the equipment and wiring.

  • Page 28: Backup Or Emergency Power

    In addition to traditional backup power systems, such as battery supply, UPS or generator-driven central supply, the EX-2.4i is designed to accommodate a multi-source DC supply, if desired, for backup power source connection. If your primary source of power is not backed up directly, you can alternatively connect a second source of power supply to a second set of pins on the DC connector.

  • Page 30: Initial Antenna Mounting

    Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual 4.3.1 Initial Antenna Mounting The antenna should be the exact model recommended by the path and site planning engineer(s). The antenna should be mounted at the proper height, mast/mounting location and polarization orientation also as determined by the path and site planning engineer(s).

  • Page 31: Transmission Line From Antenna To Egress

    Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual measures can be taken to keep the connector clear. Extra care must be taken if the antenna is installed during inclement weather to be certain that no moisture gets inside the antenna connector at any time.
  • Page 32 Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual connectors. For waveguide, the waveguide flange can typically accommodate a direct adapter to an N connector, or alternatively, the antenna can be purchased with a direct waveguide connection. But often a flexible coaxial jumper is needed to connect between the waveguide to the antenna, as waveguide is generally inflexible and can be mechanically challenging to align to the exact antenna connector location.

    Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual Once again, a drip loop may be required, and proper securing hardware and grounding needs to be accommodated. As soon as practical, the connected ends of the transmission line to the antenna and lightning arrestor should be weatherproofed.

    Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual needed to allow for ease of connection to the radio’s RF connector. A properly specified 90- degree connector can often eliminate this need. Or an installation with space accommodated around the radio for a gentle bend radius of the transmission line can also accommodate a direct connection.

  • Page 35: Configuration Using The Command Line Interface (Cli)

    Configuration Using the Command Line Interface (CLI) The EX-2.4i utilizes a CLI as the primary user interface for configuration and management of the system. The Console port may be used for serial devices, or the Ethernet MAIN or AUX ports may be used for a Telnet session over a network connection.
