PRELIMINARY Quick Start Guide

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 Bridg e 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.

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.

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).

3. 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.

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 self­threading 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. 304­800620-002). This DC Injector has an additional
wire to be connected to ground as shown on Fig. 8.
