The Integra series is a line of microwave radio products manufactured by SAF Tehnika, JSC, designed for wireless data transmission. This manual covers the Integra, Integra-S, Integra-G, and Integra-GS models, with firmware version 3.20.19 and software version 2.37.
Function Description
The Integra series FODUs (Full Outdoor Units) are designed for point-to-point microwave links, providing high-capacity data transmission. They feature Adaptive Coding and Modulation (ACM) and Automatic Transmit Power Control (ATPC) to optimize link performance and reliability under varying atmospheric conditions. The Integra-G models, specifically, incorporate a built-in Gigabit Ethernet Network Processor with three LAN ports: LAN1 (1Gbps PoE-in), LAN2 (SFP), and LAN3 (SFP). The Integra-S/Integra-GS models offer similar functionality with remote mount options for different frequency bands.
The devices support various aggregation and protection schemes, including 2+0 aggregation (link bonding) and 1+1 Hot Standby (HSB) protection, to enhance link capacity and redundancy. Traffic is split per-frame over two links in 2+0 aggregation, while 1+1 HSB uses one link at a time, with the second link's transmitters automatically muted. Header compression is also available to optimize bandwidth utilization by compressing excess protocol headers.
For networking, the Integra series supports VLANs (Virtual Local Area Networks) with port-based configuration, allowing up to 4094 different VLAN IDs. VLANs can be configured as tagged or untagged members on each LAN port, and default VLAN IDs and priorities can be set. Rate limiting can be applied to Ethernet switch ports, configuring ingress and egress rates. The devices also include a MAC address table for managing dynamic and static MAC address entries and support Spanning Tree Protocol (RSTP) for loop prevention and path redundancy. Synchronous Ethernet (SyncE) is supported to allow the Ethernet switch clock to be synchronized to an external source, ensuring stable timing for sensitive applications. Quality of Service (QoS) features include CoSQ (Class of Service Queue) scheduling, 802.1p mapping, DiffServ mapping, and MPLS EXP mapping, enabling prioritization of different types of traffic.

Antenna and Polarization:
- Default polarization for licensed frequency band radios is vertical.
- Integra series 17/24GHz FODUs are shipped with opposite polarizations pre-installed for low and high side units.
- Integra-S/Integra-GS 6-13GHz FODUs feature a twisted polarization flange, with signal polarization determined by the antenna/OMT interface. The radio always remains in a vertical position.
Usage Features
Installation:
- Mounting: Integra/Integra-G FODUs can be installed with an antenna on a pole using a mounting bracket. Integra-S/Integra-GS FODUs attach directly to the antenna adapter flange.
- Polarization Change: For Integra/Integra-G, polarization is changed by removing the FODU from the mounting bracket, rotating it 90 degrees, and reattaching. For Integra-S/Integra-GS 6-13GHz, only the antenna interface is rotated.
- Antenna Alignment: Azimuth and elevation angles are adjusted using eye screws and hex flange nuts on the mounting bracket. Each notch on the azimuth angle indicator corresponds to one degree.
- Fiber Optic Interface: A fiber conduit kit is used to connect the FO interface to SFP ports (LAN2 or LAN3).
- Remote Mount Kit: Integra-GS models support remote mount kit assembly for different frequency bands.
- Indoor Setup: A test kit (adapter flange, waveguide-to-coaxial adapter, attenuators, coaxial cable, or test tube for 17/24 GHz) is available for indoor interconnection and initial setup.
Web GUI (Graphical User Interface):
- Access: Accessed via a web browser (Chrome, Firefox, IE8+) by entering the FODU's IP address (default: 192.168.205.10 for low side, 192.168.205.11 for high side). Default credentials: admin/changeme.
