Safety Warning

Before aiming the antenna or working near the antenna, read all of this manual and follow the instructions carefully.

DO NOT STAND IN FRONT OF THE ANTENNA WHILE POWER IS ON.

Be sure to provide adequate grounding and lightning protection. Do not install the Outdoor Unit near overhead electrical wires.

This unit is intended for point-to-point operation over an unobstructed line-of-sight path. It is the responsibility of the installer to ensure the unit is properly installed in compliance with the FCC’s guidelines for maximum permissible radio frequency exposure outlined in CFR 47 Section 1.1307(b)(1), preventing excess exposure to all persons. The installed radiating device should be inaccessible to unauthorized personnel. The installed unit should be positioned to guarantee no direct continuous exposure to people within 5 feet of the antenna. During installation use caution to avoid excess exposures to directed antenna radiation within 3 feet of the front of the antenna.

The transmit power output from the Stratum 100 is less than 15 milliwatts. However, after the gain of the standard 18-inch square antenna, the Effective Radiated Power is approximately

5.2 watts. Microwave radiation can cause tissue heating, potentially affecting the eyes, causing permanent damage to vision.

Precautions when Rack Mounting the Stratum 100

When rack mounting your Stratum 100, you should the following precautions for safety and to ensure proper operation of the equipment:

The maximum ambient temperature for the Stratum 100 IDU is 50degrees C. Care should be taken that when installed in a rack, whether closed or open, the ambient temperature within the rack should not exceed 50 degrees C.

Stratum 100 IDUs have fans and ventilation holes to ensure proper air flow and maintain correct internal temperature. Do not block the fans or ventilation holes.

When mounting any equipment in racks, you must take into account mechanical loading of the rack. Heavier equipment should be placed near the bottom of the rack and equipment should not be mounted in such a way as to cause instability. Special precautions should be taken with mountings that slide out for easier access to equipment. Such mountings can cause instability of the rack resulting in unsafe conditions and possible tipping of the rack.

Ensure that the power source, wiring and over-current protection to rack mounted equipment is rated such that it can support the cumulative load of all equipment. Do not exceed the

capacity of the wiring or over-current protection. Reliable grounding of the Stratum 100 is required.

The rack should also be grounded. If power distribution strips are used, ensure that they are properly grounded.

Stratum 100 Installation and Maintenance Guide About this Manual •• 1

Introduction

The Stratum 100 is a wireless Ethernet bridge designed to deliver dedicated full-duplex 100 Mbps connectivity with fiber reliability. The Stratum 100 transports all Ethernet traffic types in addition to providing connection for two T1 channels.

A standard configuration Stratum 100 link is shipped with a pair of Indoor Units (IDUs) and Outdoor Units (ODUs). The standard configuration ODUs include integrated 18-inch square flat antennas and two-axis adjustable antenna mounts. The 18-inch flat antennas will support a full-reliability link over distances from across the street to up to 5 miles.

Some Definitions

The Stratum 100 consists of two units:

In addition, the IDU and ODU communicate via two multi-mode fibers, one each for transmit and receive. An additional twisted pair connection is required to supply power from the IDU to the ODU.

Standard Configuration

The diagram below shows the standard configuration, which has two buildings, each with their own roof-mounted ODU and the IDU inside the building bridging the traffic to the Ethernet.

• The Indoor Unit (IDU) is a rack-mounted unit which contains the electronic

bridging components. The IDU can be located in any convenient climatecontrolled location inside your building.

• The Outdoor Unit (ODU) consists of an antenna integrated with other system

components. The ODU must be mounted within line of sight of another Stratum 100 (typically on the roof) in order for communications to occur.

4 •• Introduction Stratum 100 Installation and Maintenance Guide

Installation

Installation Overview

The steps required to install the Stratum 100 are described below. The first step requires engineering experience and knowledge that is beyond the scope of this book.

Preliminary Preparation: The Path Survey & Cable Installation

Before beginning installation, you must have a path survey completed, including line-of-sight path planning, antenna supports, and pre-installation preparation. The path survey should also specify the expected signal strength between the two antennas. The path survey is typically done by your engineering staff or by your reseller. The process of doing a path survey is beyond the scope of this book. If you have questions or problems about the path survey, contact your reseller or Wavespan sales/technical support. The remainder of this manual assumes that you have completed the path survey and chosen locations for the IDUs and ODUs.

Step 1. Installing and Mounting the ODUs

As part of your path survey, an appropriate site must be selected for the two ODUs. Typically each ODU is attached to a pole on the roof, or in some cases, a tower. Installation of the appropriate pole or tower is not covered in this manual. Instead, installation should be in accordance with the findings of the Path Survey.

Note that your antenna supports require an earth ground for lightning and static protection.

Step 2. Installing the Cabling from the IDUs to the ODUs

After the ODU location has been chosen, you must run a multi-mode fiber cable and a twisted pair (DC power) cable from the ODU location to the IDU location.

Step 3. Installing the IDUs

Each IDU must be installed in either a rack or on a tabletop. Unpacking and setting up the IDU is described in detail below. Each IDU unit requires a controlled environment and an AC power outlet (3-prong, with ground).

Step 4. Aiming the Antennas

The next step requires you to aim the antennas so that they are correctly aligned and the signal strength is maximized.

Stratum 100 Installation and Maintenance Guide Installation •• 5

Step 5. Connecting to Ethernet

Once the antennas have been correctly aimed, you can connect the IDUs to the network and allow data transmission to begin.

Step 6. Verifying Correct System Operation

When all of the other steps are complete, you must check that data transmission is occurring correctly.

Step 7. (Optional) Connecting a Modem to the AUX Port

A modem can be connected to the AUX port to allow remote dial-in management for the Stratum 100. This is an optional feature.

Step 8. Connecting to a PBX or other T1 device.

The Stratum 100 can be used to provide two high-speed T1 connections between buildings. These T1 channels can be used to interconnect PBXs, channel banks, video codecs or other T1 devices, channelized or unchannelized. The T1 interface is industry standard DSX-1.

Assembling Tools and Cables Before You Begin

You will need the following tools before beginning the installation:

For installing the ODUs

• ½” socket and/or open-end wrenches

• Philips screwdriver

For the cabling between each IDU and associated ODU unit

• 62.5 micron fiber, multi-mode 850 nanometer cable (for data transmission)

Two cables are required.

• Twisted pair cable (for DC power connection) 2 pairs of 18 AWG

Note that the cable length will be different for each IDU/ODU pair, depending on the distance between them.

For installing the IDUs

• 100Base-TX or 10Base-T cable suitable for connecting the Stratum 100 to your

Ethernet network.

• Media Independent Interface Adpater suitable for connecting the Stratum 100

to your Ethernet network via another media such as fiber.

• PC or laptop running HyperTerminal, or an equivalent VT-100 emulator. The

PC or laptop must have a serial port with DB-9 male connector or adapter to accept the DB-9 female connector on the supplied serial cable.

6 •• Installation Stratum 100 Installation and Maintenance Guide

Step 1. Installing and Mounting the ODUs

The instructions below describe how to assemble and mount a single IDU. You must repeat the installation for each ODU.

Remove the ODU, pre-assembled Antenna Mount and Accessory Kit from their shipping cartons. Save all packing materials in case you need them later.

Using the foam packing material to protect the painted surfaces of the antenna, carefully place the ODU on a tabletop with the antenna facing down. The paint provides an important extra barrier to UV from sunlight.

Set aside the accessory kit. You will use this hardware to attach the antenna mount to the ODU, and to attach the complete ODU to a supporting mast.

Setting Antenna Polarization

Antenna polarization must be the same at both ends of any link. For single links, vertical polarization is a good default. There is no performance difference. For multiple links

located on the same rooftop, alternating the antenna polarization of independent links is recommended.

If the coaxial connectors are facing down the antennas operate with vertical polarization. Connectors facing right or left produces horizontal polarization.

Attaching the Antenna Mount

Slightly loosen the six 5/16-18 bolts on the Antenna Mount slotted elevation arms and angle brackets so that they can be positioned for the next step.

Position the Antenna Mount on the ODU so that the angle bracket attached to the two elevation arms is along the edge with the coax connectors (vertical polarization). The other angle bracket is bolted to the opposite edge.

Use 5/16-20x1” hex-head bolts, flat washers and lock nuts at three corners of the ODU as shown. The next step describes the corner with the ground wire.

Locate the ground wire, which has #10 and 5/16” lugs on its ends. Place a 1x5/16” hex head bolt through the 5/16” lug of the ground wire, followed by a 5/16”

flat washer. Place this bolt, ground lug and flat washer through the angle bracket and ODU corner hole nearest to the #10 ground stud on the back plate of the ODU. Secure with a flat washer and lock nut as shown.

Tighten all four corner bolts securely. Place a #10 flat washer over the #10 ground stud, followed by the ground wire and a #10 lock

washer. Tighten this nut, but do not over-torque.

Note: Avoid scratching the painted surfaces of the ODU during antenna mount installation.

Antenna Mast Requirements

The ODU must be mounted on a tubular steel or aluminum mast 1.9 to 3.9 inches in diameter using the remaining hardware supplied in the antenna mount accessory kit.

The mast must be stable, not able to bend or rotate under extreme weather conditions, and must provide a line-of-sight path to the other end of your link.

Attaching Mount On Mast

This section illustrates installation on a vertical mast. A horizontal support is perfectly acceptable.

Cut the length of rubber collar material (using a sharp knife) so that it wraps around your mast with a small gap (.10 - .25 inch) between the ends.

Select the proper size hose clamp and install the rubber collar securely on the mast. This collar is used to hold the weight of the ODU during installation and antenna alignment.

Stratum 100 Installation and Maintenance Guide Installation •• 7

For masts 1.9 to 2.5 inches in diameter use 3.5 inch long hex-head bolts for each yoke. For masts 2.5 to 3.9 inches in diameter use the 4.5 inch long hex-head bolts.

Use a safety rope, or second person to hold the ODU in position on the mast, resting on the rubber collar as shown. Install the top clamping yoke first. Install the bottom yoke last.

Note: Be careful not to drop the ODU. The weather seals protecting the antenna and microwave transceiver can be damaged.

Visually aim the antenna as precisely as possible in azimuth and elevation. Use a map and compass to set the correct direction. Tighten both yokes and elevation arms securely until you are ready for antenna aiming.

Position mount on clamp, install top yoke first Install bottom yoke last

Grounding the ODU and Mast

In Section 7.1 you connected the ODU’s ground stud to the antenna mount, which in turn must be grounded through the metallic mast. These important ground connections provide a short circuit path for static that could build up on the ODU, potentially damaging the microwave transceiver or degrading performance. This protection depends on the metallic mast or antenna support being properly connected to an earth ground.

A building’s electrical system ground is typically not a good earth ground because it can have high currents flowing through it that result from an imbalance in the distribution of the singlephase load throughout a building. Ground loops can result if two pieces of equipment are grounded to the electrical system ground and if there is a voltage difference between the ground points. For electrical protection it is important that the Stratum 100 Indoor and ODUs are grounded to an earth ground that does not have a voltage difference between the Indoor and ODUs.

Lightning Protection

Damage to your Stratum 100 Indoor or ODUs caused directly or indirectly by lightning is not covered under the manufacturer’s warranty.

If your ODU is located where nearby or direct lightning strikes are possible, especially on the top of a tall building, a lightning rod and grounding system installed by a licensed

professional are highly recommended. In addition, the use of lightning arrestors in the two coaxial cables (located in-line at the cable entry point to the building or at the rear of the IDU) with an earth ground is highly recommended. Wavespan and its authorized resellers can recommend suppliers of suitable coaxial lightning arrestors with Type-N connectors and ground posts.

The purpose of in-line lightning arrestors in the coaxial cables is to protect the IDU from high voltages induced by nearby lightning or a direct lightning strike at the ODU. The ideal location for in-line lightning arrestors would be at the point where the coaxial cables enter the building. This involves separate cables from the ODU to the point of entry, and additional cables from there to the IDU. The next best approach is to locate in-line lightning arrestors at the rear of the IDU, with a separate heavy-guage (#10 or #8) earth ground running directly from the lightning arrestors to a proper grounding system.

8 •• Installation Stratum 100 Installation and Maintenance Guide

Step 2. Installing the Cabling from the IDUs to the ODUs

Routing Cables

Label both ends of each cable, one cable for Tx (transmit) and one for Rx (receive), before you route them.

Run cables through existing roof vents if possible. Weatherproof the entry point and protect the cable from sharp metal edges. Secure the cable to prevent abrasion due to movement in the wind.

Attaching the Cables

Be sure that the IDU power switch is OFF before connecting the cables to the ODU. Attach the Tx and Rx cables to their respective connectors on the Indoor and ODUs. Hand-

tighten all connectors firmly.

Weatherproofing the Outdoor Connectors

Wrap the outdoor Tx and Rx coaxial connectors using CoaxSeal or similar weatherproofing tape to create a sealed moisture barrier around the connectors after they are tightened on the ODU.

Stratum 100 Installation and Maintenance Guide Installation •• 9

Step 3. Installing the IDUs

Environmental Requirements

The IDU requires a protected environment with its temperature maintained between 00 and 55 C (320 – 1310 F), and less than 95% relative humidity, non-condensing. The environment should be free from extremes in temperature, dust, humidity, shock, vibration and RF fields to ensure the IDU’s operation within published specifications.

Because the IDUs have cooling fans, they can be rack mounted or stacked without spaces between them. A clearance of at least one inch on both sides is required for ventilation. Be sure that the ventilating perforations on the sides and rear (near connectors) are not blocked by cables or other equipment. Better ventilation, resulting from air space around the IDU, improves equipment reliability.

Unpacking and Installing the Hardware

1. Remove the IDU from its shipping carton.

2. Locate and set aside the accessory kit (with cables and mounting hardware)

supplied in this carton. Save all packing materials in case you need them later.

3. Read the FCC Regulatory Compliance notice and Safety Warnings at the

beginning of this manual.

IDU Accessory Kit Packing List

The IDU Kit contains

• rack mounting brackets and hardware,

• rubber mounting feet, (for tabletop use only)

• AC line cord,

• RJ-45 console cable (straight-through CAT-5 cable),

• RJ-45-to-DB-9 console adapter, and

• clamp-on ferrite filter for the 10Base-T cable.

Rack Mounting the IDU

Three sets of rack mounting bracket hole patterns allow the IDU to be mounted with its connectors facing the rear or front. A center pattern also allows the IDU to be mounted in center rail racks or on the surface of a wall if the brackets are installed facing down as shown.

Attach the two rack mounting brackets on each side of the IDU as shown. Use four #832x1/2” Pan Head screws and #8 lock washers (under the screw head) for each bracket. Tighten the screws securely.

Mount the IDU in an equipment rack near your networking equipment (hub, server, switch, or router) to which it will be connected. Use two #12-24x3/4” screws in each rack bracket to mount the unit.

Tabletop Installation of the IDU

If you are installing the unit on a tabletop, attach the (4) self-adhesive rubber feet to the bottom of the unit near the corners. The rubber feet are not used if you rack mount the

IDU.

Attaching the Power Cable

Make sure the ON/OFF switch is OFF or “0”. Attach the AC power cord to the rear of the unit and plug it into a grounded AC outlet. Do not turn the power on until you have connected the management console (described below).
