Infrastructure Requirements for the BelAir100SN
This section describes the infrastructure that is required at the location where
BelAir100SN units are installed:
•“Protective Earth Ground” on page 6
•“AC Power” on page 7
•“Lightning Protection” on page 9
•“DOCSIS” on page 9
•“Ethernet” on page 13
•“Antenna Type and Placement” on page 14
Any identified specific third party parts are recommendations or examples only.
Substitution of equivalent parts is permitted. (If you are unsure of the
equivalency of a certain component, contact BelAir Networks.)
Protective Earth
Ground
For safety and functional operation, each BelAir unit must be connected to a
reliable earth ground before electrical power is applied to it. Special attention
should be made when installing the ground and connection of the ground wire
must follow local and national wiring codes. If multiple BelAir units are installed
at a single location, then each BelAir unit must be connected to the same
ground point.
The BelAir100SN is powered by the coaxial cable and is considered grounded
where connected to the cable shield, as required by US National Electric Code,
section 820-41. In addition, installers may wish to bond the BelAir100SN
ground to the messenger wire. To do so, the additional connection is to a
1/4 inch (approx. 6 mm) ground terminal with screw. Figure 2 shows the
location of the ground point and the ground terminal. Installers should follow
normal practices when grounding the unit. Installers should verify that all
grounding requirements listed in this document have been met.
Warning — Protective Earth Ground
Failure to connect the protective earth ground can result in a
shock hazard.

Figure 2: BelAir100SN Ground Point
AC Power The BelAir100SN accepts power in the range of 40 VAC to 90 VAC (-0% to
+10%) from a quasi-square wave cable UPS power supply. The BelAir100SN
also requires that the cable UPS power supply limits its output current to 30 A.
Installers must ensure that the supplied power meets these requirements.
The BelAir100SN contains a permanently attached female KS threaded power
interface (Corning Gilbert part number G-EXT-1.5-SC-T). This connector can
connect with an industry standard GRS KS male threaded connector to accept
cables of the following sizes: 0.412, 0.500, 0.625, 0.750, 0.875 and 1.000 inches.
The mating connector accepts 0.065-inch to 0.75-inch pins trimmed to
0.5 inches. Figure 3 shows the female KS connector.

Figure 3: KS Connector
A KS to F-type adapter can also be used. See Figure 4. The customer is
responsible for supplying the appropriate coaxial cable terminator with a KS
male interface or the equivalent KS to F-type adapter. BelAir Networks
recommends using Corning Gilbert part number GF-625-CH-S-T which is
designed to work well with the BelAir100SN female KS threaded power
interface.

Professional installers with appropriate credentials and experience are
responsible for installing coaxial cable terminator or the KS to F-type adapter
onto the cable power supply using industry and corporate standard procedures.
Lightning
Protection
BelAir units are not designed to survive a direct lightning hit. However, they are
intended to withstand the voltage and current surges induced from nearby
lightning activity.
The BelAir100SN is designed to sustain multiple 6 kV/3 kA lightning surges
without damage or loss of operation. The BelAir100SN does not require
lightning protection except when an external antenna is installed more than
3 feet (approx. 1 m) from the unit.
In this case, you must use lightning arrestors to protect the external antennas
ports. When lightning arrestors are used, they should be located within 3 feet
(approx. 1 m) of the BelAir100SN unit and must be grounded to both the unit
and protective earth ground. The N-type connector may be used to complete
the ground connection.
DOCSIS BelAir100SN units contain an embedded Hitron DOCSIS 3.0 cable modem,
model number BRG-35502, providing connectivity to a host network, such as
the Internet.
The cable modem is accessed directly through the GRS connector that is used
for both power input and as a DOCSIS RF interface. The cable modem is fully
DOCSIS 3.0 compliant and designed for use with 75 ohm cables.
The standard input range of a cable modem is -15 dBmV to +15 dBmV for
DOCSIS 3 and 17 dBmV for DOCSIS 3. The BelAir100SN implements
independent 0 to 20 dB digital attenuators in both upstream and downstream
paths.

Figure 5: Ethernet Pinout
The internal Ethernet interface is protected against surges induced by lightning.
It is strongly recommended to use shielded category 5e wire (such as Belden®
7929 Datatuff®) to provide additional lightning protection.
Antenna Type and
Placement
Proper antenna placement, orientation and selection are critical factors in
maximizing network performance. The BelAir antennas are typically placed
between 16 feet and 32 feet (approx. 5 m and 10 m) above ground level;
although alternate installations can be used. Additionally, directional antennas
should be located with clear lines of sight to adjacent equipment in the system
and free from obstruction by buildings, foliage and passing traffic.
Note 1: If a BelAir unit uses external antennas and is mounted on a structure
that has frequent direct lightning strikes, such as cellular telephone or
water tower, then use ¼ wavelength stubs to avoid the effects of the
lightning strikes.
Note 2: If a BelAir unit uses 5 GHz omni-directional antennas, BelAir
Networks recommends that you mount it vertically up; that is, with its
base is pointing down and its top is pointing up.
In addition, antennas that are mounted with a BelAir100SN must be located at
least 18 inches (approx. 45.7 cm) from the nearest pole to avoid shadowing
effects.

BelAir100SN Omni-directional Antenna Placement Options
Omni-directional antennas can be mounted in any of the four top corners on
the BelAir100SN unit.
Warning — Use BelAir Antennas Only
Only antennas approved by BelAir Networks may be used in
conjunction with BelAir products. Contact BelAir Networks
for an up-to-date list of available approved antennas. Use of
any other antenna may exceed regulatory requirements and
void the operator’s right to operate the radio equipment. Any
product damage caused by the use of non-BelAir approved
antennas will not be covered under BelAir’s product warranty.
Warning — Restricted Antenna Access
Installers must ensure the BelAir product is mounted in such a
manner and in such a location that access to the antennas by
the general population is minimized. During normal operation,
access to the antennas by the general population should be
limited to 8.1 inches (20.6 cm) for units with the following
radios and antennas:
• DRU radios with BelAir antennas up to 15 dBi
During normal operation, access to the antennas by the
general population should be limited to 16.5 inches (42 cm) for
units with the following radios and antennas:
• DRU radios with BelAir antennas up to 18 dBi
Warning — Minimum Distance to Local AC Power
When installing a strand mounted unit, installers must ensure
the BelAir product and external antennas maintain at all times
at least the minimum safety distance away from any electrical
power distribution cables on the pole according to local
electrical code.
