ES2440 Hardware Guide: Installation
5
WARNING: If the
Mesh Point con-
nects to outside-mount-
ed antennas, failure to
provide a low resistive
earth ground can result
in migration of voltage
from lightning or line
surges onto the premis-
es wiring, which can
cause electric shock
and/or fire within the
building or structure.
 Grounding: Ground the ES2440 by connecting a ground
wire to the grounding stud located on the left rear corner of
the chassis (
refer to Figures 2.1 and 2.2, below ).
 Radio Frequency: The Mesh Point’s internal radios conform
to the FCC’s safety standard for human exposure to RF
electromagnetic energy, provided that you follow these
guidelines:
 Do not touch or move the antennas while the unit is
transmitting or receiving.
 To safeguard Mesh Point transmitting circuitry, relocate
the Mesh Point and its antennas only when the Mesh
Point is powered off.
 When the Mesh Point is transmitting, do not hold it so
that the antenna is very close to or touching any
exposed parts of the body, especially the face or eyes.
 Antennas must be installed to provide a separation of at
least 25 cm (9.8") from all persons and any co-located
antenna or transmitter.
 Regarding use in specific environments: · Do not
operate near unshielded blasting caps or in an
explosive environment. · Limit use in a hazardous
location to the constraints imposed by the location’s
safety director. · Abide by the rules of the Federal
Aviation Administration for the use of wireless devices
on airplanes. · Restrict the use of wireless devices in
hospitals to the limits set forth by each hospital.
2.1.2 Powering Options
The ES2440 can be powered with:
 the 60W passive 802.3at PoE+ (Power over Ethernet Plus)
gigabit compatible adapter/injector via the Ethernet1 port
 the 18 VDC (volts direct current) power adapter/supply via
the
DC Power inlet
 external DC power over the DC power cable/connector
assembly, via the
DC Power inlet
In any case, the power adapter (PoE+ or DC) or cable/
connector assembly must be one obtained from Fortress
specifically for use with the ES2440, or damage to the ES2440
could result.
Whether the mid-span PoE+ injector or a DC power supply is
used to power the ES2440, the powering device, its power
cord, and the supply it plugs into must remain indoors,
protected from the weather. The connection between the
ES2440 and its indoor power source/connectors must be made
using a weatherized Ethernet or DC power cable.
The external DC power option is not intended to be a
redundant back-up supply to PoE (or vice versa). The ES2440
