Site planning
Conduct a site survey to ensure that the proposed AP and SM sites meet the requirements defined
in this section.
SITE INSTALLATION
An ePMP site typically consists of a high supporting structure such as a mast, tower or building for
the AP or SM.
There is only one Ethernet interface, a copper Cat5e connection from the AP or SM to the AP/SM
power supply and network terminating equipment. If a 1000 Base-TX (Gigabit) Ethernet connection
is required at the AP, ensure that power supply N000900L001A (ePMP 1000) or N000000L034A
(ePMP 2000) is utilized.
GROUNDING AND LIGHTNING PROTECTION
Structures, equipment and people must be protected against power surges (typically caused by
lightning) by conducting the surge current to ground via a separate preferential solid path. The
actual degree of protection required depends on local conditions and applicable local regulations.
To adequately protect an ePMP installation, both ground bonding and transient voltage surge
suppression are required.
Warning
Electro-magnetic discharge (lightning) damage is not covered under warranty. The
recommendations in this guide, when followed correctly, give the user the best protection from
the harmful effects of EMD. However 100% protection is neither implied nor possible.
Details of lightning protection methods and requirements can be found in the international
standards IEC 61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984 or
section 54 of the Canadian Electric Code.
