Safety and regulatory information
This section describes important safety and regulatory guidelines that must be observed by
personnel installing or operating ePMP equipment.
IMPORTANT SAFETY INFORMATION
Warning
To prevent loss of life or physical injury, observe the safety guidelines in this section.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
Connectorized ePMP devices must be properly grounded to protect against lightning. It is the
user’s responsibility to install the equipment in accordance with national regulations. In the USA,
follow Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 (USA). In Canada, follow
Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures
for grounding the outdoor unit, mast, lead-in wire and discharge unit, size of grounding
conductors and connection requirements for grounding electrodes. Other regulations may apply in
different countries and therefore it is recommended that installation be contracted to a
professional installer.
Powering down before servicing
Always power down and unplug the equipment before servicing.
Primary disconnect device
The ePMP power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that will be
exposed to the outdoor environment.
RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on.
Always turn off the power to the ePMP device before undertaking maintenance activities in front of
the antenna.
Minimum separation distances
Install the ePMP device so as to provide and maintain the minimum separation distances from all
persons.
The minimum separation distances for each frequency variant are specified in Calculated distances
and power compliance margins on page 431.

IMPORTANT REGULATORY INFORMATION
The ePMP product is certified as an unlicensed device in frequency bands where it is not allowed
to cause interference to licensed services (called primary users of the bands).
Radar avoidance
In countries where radar systems are the primary band users, the regulators have mandated
special requirements to protect these systems from interference caused by unlicensed devices.
Unlicensed devices must detect and avoid co-channel operation with radar systems.
The ePMP provides detect and avoid functionality for countries and frequency bands requiring
protection for radar systems.
Installers and users must meet all local regulatory requirements for radar detection. To meet these
requirements, users must set the correct country code during commissioning of the ePMP
equipment. If this is not done, installers and users may be liable to civil and criminal penalties.
Contact the Cambium helpdesk if more guidance is required.
USA and Canada specific information
The USA Federal Communications Commission (FCC) has asked manufacturers to implement
special features to prevent interference to weather radar systems that operate in the band 5600
MHz to 5650 MHz. These features must be implemented in all products able to operate outdoors in
the band 5470 MHz to 5725 MHz.
Manufacturers must ensure that such radio products cannot be configured to operate outside of
FCC rules; specifically it must not be possible to disable or modify the radar protection functions
that have been demonstrated to the FCC.
In order to comply with these FCC requirements, Cambium supplies variants of the ePMP for
operation in the USA or Canada. These variants are only allowed to operate with license keys and
country codes that comply with FCC/IC rules. In particular, operation of radio channels overlapping
the band 5600-5650 MHz is not allowed and these channels are permanently barred.
In addition, other channels may also need to be barred when operating close to weather radar
installations.
Note
To ensure compliance with FCC rules (KDB 443999: Interim Plans to Approve UNII Devices
Operating in the 5470 - 5725 MHz Band with Radar Detection and DFS Capabilities), follow
Avoidance of weather radars on page 94.
Other variants of the ePMP are available for use in the rest of the world, but these variants are not
supplied to the USA or Canada except under strict controls, when they are needed for export and
deployment outside the USA or Canada.

Specific expertise and training required for professional installers
To ensure that the ePMP is installed and configured in compliance with the requirements of
Industry Canada and the FCC, installers must have the radio engineering skills and training
described in this section. This is particularly important when installing and configuring an ePMP
system for operation in the 5 GHz band (5150 –5250 MHz –FCC only, 5250 –5350 MHz, 5470 –5725
MHz and 5725 –5850 MHz).
Avoidance of weather radars
The installer must be familiar with the requirements in FCC KDB 443999. Essentially, the installer
must be able to:
Access the FCC database of weather radar location and channel frequencies.
Use this information to correctly configure the product (using the GUI) to avoid operation on
channels that must be avoided according to the guidelines that are contained in the KDB and
explained in detail in this user guide.
In ETSI regions, the band 5600 MHz to 5650 MHz is reserved for the use of weather radars.
External antennas
When using a connectorized version of the product (as compared to the version with an integrated
antenna), the conducted transmit power must be reduced to ensure the regulatory limit on
transmitter EIRP is not exceeded. The installer must have an understanding of how to compute the
effective antenna gain from the actual antenna gain and the antenna cable losses.
The product GUI automatically applies the correct conducted power limit to ensure that it is not
possible for the installation to exceed the EIRP limit, when the appropriate values for antenna gain
are entered into the GUI.
Ethernet networking skills
The installer must have the ability to configure IP addressing on a PC and to set up and control
products using a web browser interface.
Lightning protection
To protect outdoor radio installations from the impact of lightning strikes, the installer must be
familiar with the normal procedures for site selection, bonding and grounding. Installation
guidelines for the ePMP can be found in section System planning on page 90.
Training
The installer needs to have basic competence in radio and IP network installation. The specific
requirements applicable to the ePMP must be gained by reading this user guide and by performing
sample setups at base workshop before live deployments.

Security advice
Cambium Networks systems and equipment provide security parameters that can be configured
by the operator based on their particular operating environment. Cambium recommends setting
and using these parameters following industry recognized security practices. Security aspects to
be considered are protecting the confidentiality, integrity, and availability of information and
assets. Assets include the ability to communicate, information about the nature of the
communications, and information about the parties involved.
In certain instances Cambium makes specific recommendations regarding security practices,
however the implementation of these recommendations and final responsibility for the security of
the system lies with the operator of the system.
Cambium Networks ePMP equipment is shipped with default web management interface login
