15 AVOIDING HAZARDS
Use simple precautions to protect staff and equipment. Hazards include exposure to RF
waves, lightning strikes, and power surges. This section specifically recommends actions
to abate these hazards.
15.1 PREVENTING OVEREXPOSURE TO RF ENERGY
To protect from overexposure to RF energy, install Canopy radios so as to provide and
maintain the minimum separation distances from all persons shown in Table 40.

At these and greater separation distances, the power density from the RF field is below
generally accepted limits for the general population.
−
15.1.1
NOTE:
These are conservative distances that include compliance margins. In the case
of the reflector, the distance is even more conservative because the equation
used models the reflector as a point source and ignores its physical dimensions.
Details of Calculations for Separation Distances and Power Compliance
Margins
Limits and guidelines for RF exposure come from:
◦
US FCC limits for the general population. See the FCC web site at
http://www.fcc.gov, and the policies, guidelines, and requirements in Part 1 of
Title 47 of the Code of Federal Regulations, as well as the guidelines and
suggestions for evaluating compliance in FCC OET Bulletin 65.
◦
Health Canada limits for the general population. See the Health Canada web site
at http://www.hc-sc.gc.ca/rpb and Safety Code 6.
◦
ICNIRP (International Commission on Non-Ionizing Radiation Protection)
guidelines for the general public. See the ICNIRP web site at
http://www.icnirp.de/ and Guidelines for Limiting Exposure to Time-Varying
Electric, Magnetic, and Electromagnetic Fields.

The applicable power density exposure limits from the documents referenced above are
◦ 6 W/m for RF energy in the 900-MHz frequency band in the US and Canada.
◦ 10 W/m for RF energy in the 2.4-, 5.2-, 5.4-, and 5.7-GHz frequency bands.
Peak power density in the far field of a radio frequency point source is calculated as
follows:
P•G
S=
4 πd
where
S = power density in W/m
P = RMS transmit power capability of the radio, in W
G = total Tx gain as a factor, converted from dB
d = distance from point source, in m
Rearranging terms to solve for distance yields

15.2 GROUNDING CANOPY EQUIPMENT
Effective lightning protection diverts lightning current safely to ground, Protective Earth
(PE) . It neither attracts nor prevents lightning strikes.
WARNING!
Lightning damage is not covered under the Canopy warranty. The
recommendations in Canopy guides give the installer the knowledge to protect
the installation from the harmful effects of ESD and lightning. These
recommendation must be thoroughly and correctly performed. However,
complete protection is neither implied or possible.
15.2.1
Grounding Infrastructure Equipment
To protect both your staff and your infrastructure equipment, implement lightning
protection as follows:
◦
Observe all local and national codes that apply to grounding for lightning
protection.
◦
Before you install your Canopy modules, perform the following steps:
◦
−
Engage a grounding professional if you need to do so.
−
Install lightning arrestors to transport lightning strikes away from equipment.
For example, install a lightning rod on a tower leg other than the leg to which
you mount your module.
−
Connect your lightning rod to ground.
−
Use a Canopy 300SS Surge Suppressor (or Transtector ALPU-ORTs for
OFDM BH installations) on the Ethernet cable where the cable enters any
structure. (Instructions for installing a Canopy 300SS Surge Suppressor are
provided in Procedure 28 on Page 346.)
Install your modules at least 2 feet (0.6 meters) below the tallest point on the
tower, pole, or roof.

Grounding Canopy 30/60- and 150/300-Mbps Backhaul Modules
For grounding the Canopy OFDM series backhaul modules, see the details, caveats, and
wiring schemes provided in the following documents:

Grounding SMs
This section provides lightning protection guidelines for SMs to satisfy the National
Electrical Code (NEC) of the United States. The requirements of the NEC focus on the
safety aspects of electrical shock to personnel and on minimizing the risk of fire at a
dwelling. The NEC does not address the survivability of electronic products that are
exposed to lightning surges.
The statistical incidence of current levels from lightning strikes is summarized in
Table 42.
Table 42: Statistical incidence of current from lightning strikes
Percentage
of all strikes
Peak Current
(amps)
<2
>140,000
25
>35,000
>50
>20,000
>80
>8,500
At peak, more than one-half of all surges due to direct lightning strikes exceed 20,000
amps. However, only one-quarter exceed 35,000 amps, and less than two percent
exceed 140,000 amps. Thus, the recommended Surge Suppressor (300SS) provides
a degree of lightning protection to electronic devices inside a dwelling.
Summary of Grounding Recommendations
Motorola recommends that you ground each SM as follows:
◦
Extend the SM mounting bracket extend to the top of the SM or higher.
◦
Ground the SM mounting bracket via a 10-AWG (6 mm ) copper wire connected
by the most direct path either to an eight foot-deep ground rod or to the ground
bonding point of the AC power service utility entry. This provides the best
assurance that
◦
172
−
lightning takes the ground wire route
−
the ground wire does not fuse open
−
your grounding system complies with NEC 810-15.
Ground the Canopy Surge Suppressor 300SS ground lug to the same ground
bonding point as above, using at least a 10-AWG (6 mm ) copper wire. This
provides the best assurance that your grounding system complies with
NEC 810-21.

Release 8
Installation and Configuration Guide
Grounding Scheme
The proper overall antenna grounding scheme per the NEC is illustrated in Figure 134 on
Page 347. In most television antenna or dish installations, a coaxial cable connects the
outdoor electronics with the indoor electronics. To meet NEC 810-20, one typically uses
a coaxial cable feed-through block that connects the outdoor coax to the indoor coax and
also has a screw for attaching a ground wire. This effectively grounds the outer shield of
the coax. The block should be mounted on the outside of the building near the AC main
panel such that the ground wire of the block can be bonded to the primary grounding
electrode system of the structure.
For residential installs, in most cases an outdoor rated unshielded twisted pair (UTP)
cable is sufficient. To comply with the NEC, Motorola provides the antenna discharge
unit, 300SS, for each conductor of the cable. This 300SS must be
◦
◦
positioned
−
outside the building.
−
as near as practicable to the power service entry panel of the building and
attached to the AC main power ground electrode, or attached to a grounded
water pipe.
−
far from combustible material.
grounded in accordance with NEC 810-21, with the grounding wire attached to
the screw terminal.
The metal structural elements of the antenna mast also require a separate grounding
conductor. Section 810-15 of the NEC states:
Masts and metal structures supporting antennas shall be grounded in
accordance with Section 810-21.
As shown in Figure 134 on Page 347, the Motorola recommendation for grounding the
metal structural element of the Canopy mounting bracket (SMMB1) is to route the
grounding wire from the SMMB1 down to the same ground attachment point as is used
for the 300SS discharge unit.
Use 10-AWG (6 mm ) Copper Grounding Wire
According to NEC 810-21 3(h), either a 16-AWG copper clad steel wire or a 10-AWG
copper wire may be used. This specification appears to be based on mechanical strength
considerations and not on lightning current handling capabilities.
For example, analysis shows that the two wire types are not equivalent when carrying
a lightning surge that has a 1-microsecond rise by 65-microsecond fall:
◦
The 16-AWG copper clad steel wire has a peak fusing current of 35,000 amps
and can carry 21,000 amps peak, at a temperature just below the ignition point
for paper (454° F or 234° C).
◦
The 10-AWG copper wire has a peak fusing current of 220,000 amps and can
carry 133,000 amps peak, at the same temperature.
It is insufficient to merely use the green wire ground in a duplex electrical outlet box for grounding
of the antenna discharge unit.
Issue 2, December 2006
Draft 2 for Regulatory Review
173
Installation and Configuration Guide
Release 8
Based on the electrical/thermal analysis of these wires, Motorola recommends 10-AWG
copper wire for all grounding conductors. Although roughly double the cost of 16-AWG
copper clad steel wire, 10-AWG copper wire handles six times the surge current from
lightning.
Shielding is not Grounding
In part, NEC 810-21 states:
A lightning arrester is not required if the lead-in conductors are enclosed in a
continuous metal shield, such as rigid or intermediate metal conduit, electrical
metallic tubing, or any metal raceway or metal-shielded cable that is effectively
grounded. A lightning discharge will take the path of lower impedance and jump
from the lead-in conductors to the metal raceway or shield rather than take the
path through the antenna coil of the receiver.
However, Motorola does not recommend relying on shielded twisted pair cable for
lightning protection for the following reasons:
◦
Braid-shielded 10Base-T cable is uncommon, if existent, and may be unsuitable
anyway.
◦
At a cost of about two-thirds more than 10-AWG copper UTP, CAT 5
100Base-TX foil-shielded twisted pair (FTP) cable provides a 24-AWG drain wire.
If this wire melts open during a lightning surge, then the current may follow the
twisted pair into the building.
More than 80 percent of all direct lightning strikes have current that exceeds
8,500 amps (see Table 42 on Page 172). A 24-AWG copper wire melts open at
8,500 amps from a surge that has a 1-microsecond by 70-microsecond
waveform. Hence, reliance on 24-AWG drain wire to comply with the intent of
NEC 810-21 is questionable.
Shielded twisted pair cable may be useful for mitigation of interference in some
circumstances, but installing surge suppressors and implementing the ground
recommendations constitute the most effective mitigation against lightning damage.

15.3 CONFORMING TO REGULATIONS
For all electrical purposes, ensure that your network conforms to applicable country and
local codes, such as the NEC (National Electrical Code) in the U.S.A. If you are uncertain
of code requirements, engage the services of a licensed electrician.
15.4 PROTECTING CABLES AND CONNECTIONS
Cables that move in the wind can be damaged, impart vibrations to the connected device,
or both. At installation time, prevent these problems by securing all cables with cable ties,
cleats, or PVC tape.
174
Draft 2 for Regulatory Review
Issue 2, December 2006
Release 8
Installation and Configuration Guide
Over time, moisture can cause a cable connector to fail. You can prevent this problem by
◦
using cables that are filled with a dielectric gel or grease.
◦
including a drip loop where the cable approach to the module (typically a CMM2
or CMMmicro) is from above.
◦
wrapping the cable with weather-resistant tape.
On a module with an external antenna, use accepted industry practices to wrap the
connector to prevent water ingress. Although the male and female N-type connectors
form a gas-tight seal with each other, the point where the cable enters each connector
can allow water ingress and eventual corrosion. Wrapping and sealing is critical to longterm reliability of the connection.
Possible sources of material to seal that point include
◦
the antenna manufacturer (material may have been provided in the package with
the antenna).
◦
Universal Electronics (whose web site is http://www.coaxseal.com), who markets
a weather-tight wrap named Coax-Seal.
Perform the following steps to wrap the cable.
Procedure 4: Wrapping the cable
1. Start the wrap on the cable 0.5 to 2 inches (about 1.5 to 5 cm) from the
connection.
2. Wrap the cable to a point 0.5 to 2 inches (about 1.5 to 5 cm) above the
connection.
3. Squeeze the wrap to compress and remove any trapped air.
4. Wrap premium vinyl electrical tape over the first wrap where desired for abrasion
resistance or appearance.
5. Tie the cable to minimize sway from wind.

16 TESTING THE COMPONENTS
Before you install any component into your Canopy network, allow yourself the
opportunity to discover that the component is defective. If you always follow the
preliminary steps in this section, you will save
◦
installation and removal costs for a component that will not function.
◦
time in the process of replacing the defective component.
The best practice is to connect all the components—BHs, APs, GPS antenna, and CMM2
or CMMmicro—in a test setting and initially configure and verify them before deploying
them to an installation. However, circumstances or local practice may require a different
practice. In this case, appropriately modify the following procedures.
16.1 UNPACKING COMPONENTS
When you receive Canopy products, carefully inspect all shipping boxes for signs of
damage. If you find damage, immediately notify the transportation company.
As you unpack the equipment, verify that all the components that you ordered have
arrived. Save all the packing materials to use later, as you transport the equipment to and
from installation sites.
16.2 CONFIGURING FOR TEST
You can use either of two methods to configure an AP or BHM:
◦
Use the Quick Start feature of the product. For more information on Quick Start,
see Quick Start Page of the AP on Page 185.
◦
Manually set each parameter.
After you change any configuration parameter, to put the change into effect, you must do
both of the following:
1. Click the Save button to temporarily save the change(s).
2. Click the Reboot button to reboot the module and implement
the change(s).
16.2.1
Configuring the Computing Device for Test
If your computer is configured for Dynamic Host Configuration Protocol (DHCP),
disconnect the computer from the network. If your computer is instead configured for
static IP addressing
◦
set the static address in the 169.254 network
◦
set the subnet mask to 255.255.0.0.

Default Module Configuration
From the factory, the Canopy AP, SM, and BH are all configured to not transmit on any
frequency. This configuration ensures that you do not accidentally turn on an
unsynchronized module. Site synchronization of modules is required because

when one module transmits while an unintended module nearby receives signal,
the transmitting module may interfere with or desense the receiving module. In
this context, interference is self-interference (within the same Canopy network).
Component Layout
As shown in Figure 52, the base cover of the module snaps off when you depress a lever

Standards for Wiring
Canopy modules automatically sense whether the Ethernet cable in a connection is wired
as straight-through or crossover. You may use either straight-through or crossover cable
to connect a network interface card (NIC), hub, router, or switch to these modules. For a
straight-through cable, use the EIA/TIA-568B wire color-code standard on both ends. For
a crossover cable, use the EIA/TIA-568B wire color-code standard on one end, and the
EIA/TIA-568A wire color-code standard on the other end.
Where you use the Canopy AC wall adapter
16.2.8
◦
the power supply output is +24 VDC.
◦
the power input to the SM is +11.5 VDC to +30 VDC.
◦
the maximum Ethernet cable run is 328 feet (100 meters).
Best Practices for Cabling
The following practices are essential to the reliability and longevity of cabled connections:
16.2.9
◦
Use only shielded cables to resist interference.
◦
For vertical runs, provide cable support and strain relief.
◦
Include a 2-ft (0.6-m) service loop on each end of the cable to allow for thermal
expansion and contraction and to facilitate terminating the cable again when
needed.
◦
Include a drip loop to shed water so that most of the water does not reach the
connector at the device.
◦
Properly crimp all connectors.
◦
Use dielectric grease on all connectors to resist corrosion.
◦
Use only shielded connectors to resist interference and corrosion.
Recommended Tools for Wiring Connectors
The following tools may be needed for cabling the AP:
◦
RJ-11 crimping tool
◦
RJ-45 crimping tool
◦
electrician scissors
◦
wire cutters
◦
cable testing device.

=========================== end of procedure ===========================
The Session Status tab provides information about each SM that has registered to
the AP. This information is useful for managing and troubleshooting a Canopy system.
All information that you have entered in the Site Name field of the SM displays in the
Session Status tab of the linked AP.
The Session Status tab also includes the current active values on each SM (LUID) for
MIR, CIR, and VLAN, as well as the source of these values (representing the SM itself,
BAM, or the AP and cap, if any—for example, APCAP as shown in Figure 64 above).
L indicates a Canopy Lite SM, and D indicates from the device. As an SM registers to
the AP, the configuration source that this page displays for the associated LUID may
change. After registration, however, the displayed source is stable and can be trusted.
The Session Status tab of the AP provides the following parameters.
LUID
This field displays the LUID (logical unit ID) of the SM. As each SM registers to the AP,
the system assigns an LUID of 2 or a higher unique number to the SM. If an SM loses
registration with the AP and then regains registration, the SM will retain the same LUID.
NOTE:
The LUID association is lost when a power cycle of the AP occurs.
MAC
This field displays the MAC address (or electronic serial number) of the SM.
State
This field displays the current status of the SM as either
◦
IN SESSION to indicate that the SM is currently registered to the AP.
◦
IDLE to indicate that the SM was registered to the AP at one time, but now is not.
This field also indicates whether the encryption scheme in the module is enabled.

Site Name
This field indicates the name of the SM. You can assign or change this name on the
Configuration web page of the SM. This information is also set into the sysName SNMP
MIB-II object and can be polled by an SNMP management server.
Software Version
This field displays the software release that operates on the SM, the release date and
time of the software.
Software Boot Version
This field indicates the CANOPYBOOT version number.
FPGA Version
This field displays the version of FPGA that runs on the SM.
Session Timeout
This field displays the timeout in seconds for management sessions via HTTP, telnet, or
ftp access to the SM. 0 indicates that no limit is imposed.
AirDelay
This field displays the distance of the SM from the AP. To derive the distance in meters,
multiply the displayed number by 0.3048. At close distances, the value in this field is
unreliable.
Session Count
This field displays how many sessions the SM has had with the AP. Typically, this is the
sum of Reg Count and Re-Reg Count. However, the result of internal calculation may
display here as a value that slightly differs from the sum.
If the number of sessions is significantly greater than the number for other SMs, then this
may indicate a link problem or an interference problem.
Reg Count
When an SM makes a registration request, the AP checks its local data to see whether it
considers the SM to be already registered. If the AP concludes that the SM is not, then
the request increments the value of this field.
Re-Reg Count
When an SM makes a registration request, the AP checks its local data to see whether it
considers the SM to be already registered. If the AP concludes that the SM is not, then
the request increments the value of this field. Typically, a Re-Reg is the case where both
◦
an SM attempts to reregister for having lost communication with the AP.
◦
the AP has not yet observed the link to the SM as being down.
A high number in this field is often an indication of link instability or interference problems.
RSSI, Jitter, and Power Level (Avg/Last)
The Session Status tab shows the received Power Level in dBm and Jitter. Proper
alignment maximizes Power Level and minimizes Jitter. As you refine alignment, you
should favor lower jitter over higher dBm. For example, if coarse alignment gives an SM
a power level of −75 dBm and a jitter measurement of 5, and further refining

the alignment drops the power level to −78 dBm and the jitter to 2 or 3, use the refined
alignment, with the following caveats:
◦
When the receiving link is operating at 1X, the Jitter scale is 0 to 15 with desired
jitter between 0 and 4.
◦
When the receiving link is operating at 2X, the Jitter scale is 0 to 15 with desired
jitter between 0 and 9.
For historical relevance, the Session Status tab also shows the RSSI, the unitless
measure of power. Use Power Level and ignore RSSI. RSSI implies more accuracy and
precision than is inherent in its measurement.

1. In one hand, securely hold the top (larger shell) of the BH that you intend to
deploy as a timing master. With the other hand, depress the lever in the back of
the base cover (smaller shell). Remove the base cover.
2. Plug one end of a CAT 5 Ethernet cable into the timing master.
3. Plug the other end of the Ethernet cable into the jack in the pig tail that hangs
from the power supply.
4. Plug the other connector of the pig tail into the Ethernet jack of the computing
device.
WARNING!
From this point until you remove power from the BH, stay at least as far from the
BH as the minimum separation distance specified under Preventing
Overexposure to RF on Page 169.
5. Plug the power supply into an electrical outlet.
6. Power up the computing device.
7. Start the browser in the computing device.
=========================== end of procedure ===========================
The Canopy BH interface provides a series of web pages to configure and monitor the
unit. These screens are subject to change by subsequent software releases.
You can access the web-based interface through only a computing device that is either
directly connected or connected through a network to the BH. If the computing device is
not connected to a network when you are configuring the module in your test
environment, and if the computer has used a proxy server address and port to configure
a Canopy module, then you may need to first disable the proxy setting in the computer.
To toggle the computer to not use the proxy setting, perform Procedure 6 on Page 185.
In the address bar of your browser, enter the IP address of the BHM (default is
169.254.1.1). The BHM responds by opening the General Status tab of its Home page.

Figure 69: Time tab of BHM, example
To have each log in the BHM correlated to a meaningful time and date, either a reliable
network element must pass time and date to the BHM or you must set the time and date
whenever a power cycle of the BHM has occurred. A network element passes time and
date in any of the following scenarios:
◦
A connected CMM2 passes time and date (GPS time and date, if received).
◦
A connected CMMmicro passes the time and date (GPS time and date, if
received), but only if the CMMmicro is operating on CMMmicro Release 2.1 or
later release. (These releases include an NTP server functionality.)
◦
A separate NTP server is addressable from the BHM.
If the BHM should derive time and date from either a CMMmicro or a separate NTP
server, enter the IP address of the CMMmicro or NTP server on this tab. To force the
BHM to derive time and date before the first (or next) 15-minute interval query of the NTP
server, click Get Time through NTP.

Beginning the Test of Point-to-Point Links
To begin the test of your BH link, in the Remote Subscribers tab of the BHM, click the link
to the BHS. The BHS GUI opens to the General Status tab of its Home page.
An example of the BHS General Status tab is displayed in Figure 71.
Figure 71: General Status tab of BHS, example
The General Status tab provides information on the operation of this BHS. This is the tab
that opens by default when you access the GUI of the BHS. The General Status tab
provides the following read-only fields.
Device Type
This field indicates the type of the Canopy module. Values include the frequency band of
the BHS, its module type, and its MAC address.
Software Version
This field indicates the Canopy system release, the time and date of the release, the
modulation rate, and whether communications involving the module are secured by DES
or AES encryption (see Encrypting Canopy Radio Transmissions on Page 371). If you
request technical support, provide the information from this field.

Software BOOT Version
This field indicates the version of the CANOPYBOOT file. If you request technical
support, provide the information from this field.
Board Type
This field indicates the series of hardware. See Designations for Hardware in Radios on
Page 367.
FPGA Version
This field indicates the version of the field-programmable gate array (FPGA) on the
module. When you request technical support, provide the information from this field.
Uptime
This field indicates how long the module has operated since power was applied.
System Time
This field provides the current time. When a BHS registers to a BHM, it inherits the
system time, which is displayed in this field as GMT (Greenwich Mean Time).
Ethernet Interface
This field indicates the speed and duplex state of the Ethernet interface to the BHS.
Session Status
This field displays the following information about the current session:
◦
Scanning indicates that this SM currently cycles through the RF frequencies that
are selected in the Radio tab of the Configuration page.
◦
Syncing indicates that this SM currently attempts to receive sync.
◦
Registering indicates that this SM has sent a registration request message to
the AP and has not yet received a response.
◦
Registered indicates that this SM is both
◦
−
registered to an AP.
−
ready to transmit and receive data packets.
Alignment indicates that this SM is in an aiming mode. See Table 44 on
Page 179.
Registered AP
This field displays the MAC address of the BHM to which this BHS is registered.
RSSI, Power Level, and Jitter
The General Status tab shows the received Power Level in dBm and Jitter. Proper
alignment maximizes Power Level and minimizes Jitter. As you refine alignment, you
should favor lower jitter over higher dBm. For example, if coarse alignment gives the BHS
a power level of −75 dBm and a jitter measurement of 5, and further refining
the alignment drops the power level to −78 dBm and the jitter to 2 or 3, use the refined
alignment, with the following caveats:
◦
When the receiving link is operating at 1X, the Jitter scale is 0 to 15 with desired
jitter between 0 and 4.
Issue 2, December 2006
Draft 2 for Regulatory Review
211
Installation and Configuration Guide
◦
Release 8
When the receiving link is operating at 2X, the Jitter scale is 0 to 15 with desired
jitter between 0 and 9.
For historical relevance, the General Status tab also shows the RSSI, the unitless
measure of power. Use Power Level and ignore RSSI. RSSI implies more accuracy and
precision than is inherent in its measurement.
NOTE:
Unless the page is set to auto-refresh, the values displayed are from the instant
the General Status tab was selected. To keep a current view of the values,
refresh the browser screen or set to auto-refresh.
Air Delay
This field displays the distance in feet between the BHS and the BHM. To derive the
distance in meters, multiply the value of this parameter by 0.3048. Distances reported as
less than 200 feet (61 meters) are unreliable.
Site Name
This field indicates the name of the physical module. You can assign or change this
name in the SNMP tab of the BHS Configuration page. This information is also set into
the sysName SNMP MIB-II object and can be polled by an SNMP management server.
Site Contact
This field indicates contact information for the physical module. You can provide or
change this information in the SNMP tab of the BHS Configuration page. This information
is also set into the sysName SNMP MIB-II object and can be polled by an SNMP
management server.
