NM5-MB-49Wireless Network Bridge

Marquee™ Bridge 49 PRELIMINARY Quick Start Guide MNL-500267-001 – Rev ED2 1 Aug 2004 Introduction The Marquee Bridge 49 (MB-49) is a complete 4.9 GHz wireless point-to-point (p-p) or point-to-multipoint (p-mp) system that links two Ethernet LANs together. It consists of two high-gain directional antennas and a pair of OFDM radios in a rugged outdoor enclosure. They connect to the LAN's Ethernet Switch on each end with an outdoor-rated Ethernet cable ordered separately. It is ideal for connecting two office LANs together, or for linking a WIPOP site to an Internet backbone. The Marquee Bridge 49 uses TurboCell software which supports VLAN bridging (802.1q protocol). The Marquee Bridge 49 will accommodate virtually an unlimited number of client MAC addresses on each side of the link. The unit currently supports a single channel. Marquee Bridge 49 Kit Contents 1. Two outdoor radios with RF connector for external antenna and mounting hardware 2. Two Cat 5 DC Power Injectors (surge protected Power Injectors are available as an option) 3. Two 110/240 VAC to 48 VDC power supplies 4. Windows-based YDI Configurator software 5. Two 3 foot low-loss coaxial cables 6. Two high-gain directional antennas YDI EtherAnt outdoor Ethernet cables must be ordered separately. Available lengths are 50, 100, 200, or 300 ft. Figure 1 – Marquee Bridge 49 Kit Contents The Marquee Bridge 49 is intended for professional installation only on fixed outdoor structures. Please review the entire manual before powering up or deploying these units. Installation NOTE: All connectors must be properly water-proofed with all-weather electrical tape, Permagum, or equivalent. Do not use Silicon glue. The Marquee Bridge 49 radio unit is installed by means of a pole mount adaptor bracket that is secured to the pole using two metal hose type clamps. Figure 1 shows the hardware provided to mount the outdoor RF Unit. 1. Install the outdoor unit pole mount adaptor bracket using the supplied metal hose type clamps (see Figure 2). Figure 2 – Detail Showing Outdoor Unit Pole Mount Bracket 2. Align the four mounting studs on the outdoor unit with the bracket holes (see Figure 3) and secure to the bracket by pushing down the latches as shown in Figures 4a and 4b.

Ensuring that there is no DC power applied to the DC Power Injector, plug the round connector of the outdoor Ethernet cable into the rear jack of the unit (Fig. 5), making sure the notch is correctly aligned with the tab on the jack as shown in Figure 6, then turn the round locking nut clockwise as you push in until it securely fastens onto the jack. WARNING: Please verify that the round connector is properly plugged into the rear jack of the antenna prior to connecting DC power because it is possible to push it in the wrong way if enough force is used. If DC Power is applied while you are attempting to insert the round connector into the jack, it is possible that, as you rotate the plug in an effort to find the key, DC power pins will momentarily touch the Ethernet pins. If this happens the Ethernet circuitry on the board will be damaged. Any harm caused by this action will not be covered by the factory warranty and will be a billable repair. Figure 5 – Connecting the Outdoor Ethernet Cable Figure 6 – Plugging the Round Connector 4. Attach the other end of the outdoor Ethernet cable to the Cat 5 DC Power Injector at port RJ-45 labeled “To ANT.” NOTE: The Cat 5 DC Power Injector is not in a waterproof enclosure and must be protected from the weather. It can be permanently mounted to a surface using the double stick tape found on the back of it. 5. Connect the Ethernet cable labeled “To PC or Router” from the Cat 5 DC Power Injector to your router, switch or hub. If you connect to a computer or PC, a crossover cable or adapter will be needed. 6. If your unit is placed on a non-metal pole or structure, install a #6 AWG insulated ground cable (not provided) to the ground connector in the back of the radio as shown in Figure 7. Use a self- threading screw and a flat washer to fasten the earth lug. This provides safeguard against lightning. For maximum protection, YDI also recommends the use of its optional surge protected DC Injector available from your YDI dealer (part No. 304- 800620-002). This DC Injector has an additional wire to be connected to ground as shown on Fig. 8.

Plug the antenna coaxial cable into the N-type female connector of the unit as shown in Figure 9. Plug the AC Adapter into an AC outlet and connect it to the “DC Power” jack on the Cat 5 DC Power Injector. Perform antenna alignment procedures at both sites. Proper antenna alignment is crucial for the correct operation of the Marquee Bridge 49 system and should only be accomplished by experienced professionals. After that your installation is complete. WARNING: The MB-49 must be operated with a proper antenna or microwave terminator plugged into the N-type female jack of the unit. Operating the unit with nothing connected to the antenna jack may result in damage to the TX section of the unit which will not be covered by the factory warranty and will be a billable repair.

Document 8206, Rev. 0 FCC ID: NM5-MB-49 RF Exposure Test Report Washington Laboratories, Ltd July 2004 RF Exposure Test Report for YDI Wireless MARQUEE BRIDGE RADIO Model Number MB-EXT 49 FCC ID: NM5-MB-49 July 21, 2004 WLL PROJECT #: 8206X This report may not be reproduced, except in full, without the prior written consent of Washington Laboratories, Ltd. RF Exposure Test Report Document 8206-MPE, Rev. 0 FCC ID: NM5-MB-49 RF Exposure Test Report Washington Laboratories, Ltd July 2004 1 RF Exposure Test Report for FCC ID: NM5-MB-49 1.0 Introduction This report has been prepared on behalf of YDI Wireless Marquee Bridge Radio Transmitter, Model MB-EXT 49 to show compliance with the RF exposure requirements as defined in FCC §1.1307. 1.1 Requirements Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable and are defined as follows: ƒ Fixed Installations: fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. ƒ Mobile Devices: a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. ƒ Portable Devices: a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). For this test report the YDI Wireless Marquee Bridge Radio is classified as a “Fixed Installation Device” and therefore must meet the limits as specified in §1.307. Document 8206-MPE, Rev. 0 FCC ID: NM5-MB-49 RF Exposure Test Report Washington Laboratories, Ltd July 2004 2 The FCC also categorizes the use of the device as based upon the user’s awareness and ability to exercise control over his or her exposure. The two categories defined are Occupational/ Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are defined as follows: ƒ Occupational/Controlled Exposure: In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. This exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. Awareness of the potential for RF exposure in a workplace or similar environment can be provided through specific training as part of a RF safety program. If appropriate, warning signs and labels can also be used to establish such awareness by providing prominent information on the risk of potential exposure and instructions on methods to minimize such exposure risks. ƒ General Population/Uncontrolled Exposure: The general population / uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. Warning labels placed on low-power consumer devices such as cellular telephones are not considered sufficient to allow the device to be considered under the occupational/controlled category, and the general population/uncontrolled exposure limits apply to these devices. Since there are no warnings or training associated with this unit and it can be used by anyone, the YDI Wireless Model MB-EXT 49 is evaluated to the General Population/Uncontrolled Exposure limits. 1.2 Radio Frequency Radiation Exposure Evaluation The highest RF output power of the unit was measured at 10.5dBm at 4965 MHz. According to §1.1310 of the FCC rules, the power density limit for General Population/Uncontrolled Exposure is 1mW/cm 2 . To comply with the exposure limits for this section, individuals must maintain a safe distance from the transmit antenna. The following formula was used to calculate the minimum safe distance: 2 4R PG S π = Document 8206-MPE, Rev. 0 FCC ID: NM5-MB-49 RF Exposure Test Report Washington Laboratories, Ltd July 2004 3 Where: S = Power Density P = Output Power at the Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna For this device, the calculation is as follows: S = FCC Limit = 1mW/cm 2 P = Output Power = 93.3 mW G = Gain = 10 dBi = INVLOG(10/10) = 10 (currently, this is the only antenna specified by the applicant, however, other antennas may be chosen at a later date and the minimum safe mounting distance must be determined) Solving for the minimum safe distance based on a 10dBi antenna: R = {(11.22mW)(10}/{(12.56)(1mW/cm 2 )} 1/2 = 3 cm This unit is only installed by professionals and is limited in practice to i…

RF Exposure Test Report Document 8206-MPE, Rev. 1 FCC ID: NM5-MB-49 RF Exposure Test Report Washington Laboratories, Ltd July 2004 1 RF Exposure Test Report for FCC ID: NM5-MB-49 1.0 Introduction This report has been prepared on behalf of YDI Wireless Marquee Bridge Radio Transmitter, Model MB-EXT 49 to show compliance with the RF exposure requirements as defined in FCC §1.1307. 1.1 Requirements Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable and are defined as follows: ƒ Fixed Installations: fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. ƒ Mobile Devices: a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. ƒ Portable Devices: a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). For this test report the YDI Wireless Marquee Bridge Radio is classified as a “Fixed Installation Device” and therefore must meet the limits as specified in §1.307. Document 8206-MPE, Rev. 1 FCC ID: NM5-MB-49 RF Exposure Test Report Washington Laboratories, Ltd July 2004 2 The FCC also categorizes the use of the device as based upon the user’s awareness and ability to exercise control over his or her exposure. The two categories defined are Occupational/ Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are defined as follows: ƒ Occupational/Controlled Exposure: In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. This exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. Awareness of the potential for RF exposure in a workplace or similar environment can be provided through specific training as part of a RF safety program. If appropriate, warning signs and labels can also be used to establish such awareness by providing prominent information on the risk of potential exposure and instructions on methods to minimize such exposure risks. ƒ General Population/Uncontrolled Exposure: The general population / uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. Warning labels placed on low-power consumer devices such as cellular telephones are not considered sufficient to allow the device to be considered under the occupational/controlled category, and the general population/uncontrolled exposure limits apply to these devices. Since there are no warnings or training associated with this unit and it can be used by anyone, the YDI Wireless Model MB-EXT 49 is evaluated to the General Population/Uncontrolled Exposure limits. 1.2 Radio Frequency Radiation Exposure Evaluation The highest RF output power of the unit was measured at 10.5dBm at 4965 MHz. According to §1.1310 of the FCC rules, the power density limit for General Population/Uncontrolled Exposure is 1mW/cm 2 . To comply with the exposure limits for this section, individuals must maintain a safe distance from the transmit antenna. The following formula was used to calculate the minimum safe distance: 2 4R PG S π = Document 8206-MPE, Rev. 1 FCC ID: NM5-MB-49 RF Exposure Test Report Washington Laboratories, Ltd July 2004 3 Where: S = Power Density P = Output Power at the Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna For this device, the calculation is as follows: S = FCC Limit = 1mW/cm 2 P = Output Power = 11.22 mW G = Gain = 10 dBi = INVLOG(10/10) = 10 (currently, this is the only antenna specified by the applicant, however, other antennas may be chosen at a later date and the minimum safe mounting distance must be determined) Solving for the minimum safe distance based on a 10dBi antenna: R = {(11.22mW)(10}/{(12.56)(1mW/cm 2 )} 1/2 = 3 cm This unit is only installed by professionals and is…
