    Sight (LOS) to operate reliably. Because of the extremely high data bandwidth provided by the Gigalink system (1.25Gbps) it is likely that our radio systems will be utilized as a critical or primary network connection. This absolute reliance on our systems for connectivity demands a focused attention to detail in order to assure un-interrupted operation.

  • Page 6: Fcc Compliance Statement

    FCC Compliance Statement The Terabeam Gigalink family of products is type-certified for unlicensed operation in compliance with FCC Part 15.255. Terabeam Gigalink radio products are factory set for frequency, frequency stability and transmitter power levels. No user-authorized adjustments are provided. Changes or modifications not expressly approved by the party responsible for compliance will void the user’s authority to operate this equipment.

    57.05 – 64.0 GHz. Due to the unlicensed status of this band, FCC license or special authorization is not required to operate our Gigalink systems. In addition, the high atmospheric absorption of RF energy at this frequency virtually eliminates any chance of interference from competing systems or unauthorized interception of the transmitted signal.
  • Page 8 Unpacking the Kit and Verifying Contents Your Gigalink system will arrive in two separate boxes, one containing the high band radio terminal, DC Connector kit, mounting hardware and documentation and one containing the low band radio terminal, DC Connector kit, mounting hardware and documentation. The contents of both boxes should be identical with the exception of the fiber optic loop-back cable, supplied only with one terminal.

  • Page 10: Gigamon Software Installation

    The SNMP is accessed through the Gigamon™ Graphic User Interface (GUI). The Gigamon Interface is the primary tool for precision alignment of the Gigalink terminals. Through Gigamon, the SNMP utility is also used to set terminal configurations and provide ongoing monitoring of critical radio parameters.

If problems are encountered during the Gigamon monitor software installation process, refer to the more detail description of the Gigalink SNMP utility and Gigamon monitoring software (sections 3 and 4) of the enclosed “Users Manual”.

  • Page 12: Electrical Services

    Electrical Power The Gigalink Model 6451e terminal operates on a single –48VDC supply. Power may be provided from a regulated power supply or battery plant. The installer must provide a 3 stranded conductor DC power cable of a gauge sufficient for the intended application.

  • Page 13: Network Interfaces

    Building Ground Network Interfaces The Gigalink terminals utilize a weatherproof, FC type fiber connector on the radio terminal and a proprietary 10BaseT interface for SNMP communications. Network Fiber must be supplied to the radio terminal location and terminated in FC Male. The supplied Gigamon adapter cable (Figure 1, Item 4) can be permanently installed for the SNMP network connection by attaching a standard CAT 5 coupler and cable.

    Before actual terminal mounting can be accomplished, it is necessary to attach the Pan and Tilt Gimbal Mount to the Gigalink radio terminal housing. The necessary hardware for this attachment is provided with the Pan and Tilt Gimbal Mount # 2289-1 and consists of (4) M8 x 1.5cm stainless steel bolts, flat washers and lock washers.

  • Page 19: Rough Mechanical (Visual) Alignment

    Nuts (hardware kit #2901) Rough Mechanical (Visual) Alignment Once the Gigalink Radio Terminals are securely fastened to the mounting locations, the installer should visually align the terminals. Visual alignment is accomplished by loosening both the C Bracket Attachment bolts and L Bracket Mounting bolts slightly. With these (7) bolts loosened the terminal can be aligned (aimed) toward the other terminal by sighting along the radio housing body.

  • Page 20: Final Terminal Alignment

    Connecting Network Services Once the power has been applied to the Gigalink terminal, Network services can be connected and verified. The network Fiber connections to the Gigalink terminal are Type FC male terminated fiber optic cables. Make these connections by aligning the connector body index tab, then tightening the outer collar in a clockwise rotation.

  • Page 36 AND between this Subnet Mask and destination IP address to find out if the destination is in its local subnet. The Gigalink terminal needs to know the local “Subnet Mask” because if the destination is not within its local network, the Gigalink terminal will send the packet to the default destination, the Gateway, which is a router.
