ES520 Hardware Guide: Installation
8
NOTE: The ES520
complies with UL
60950-1 safety specifica-
tions. It has a
UL (NE-
MA) 3/3S/4
(and
IEC60529) environmen-
tal rating. The Front-
panel Cover Plate of the
ES520 Weatherizing Kit
includes a “Raintight”
label.
 Antennas must be installed to provide a separation of at
least 20 cm (7.9") 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 Outdoor Siting Requirements and Restrictions
Mesh Points intended to be used out-of-doors must be fully
weatherized and mast-mounted (as described in sections 2.3
and 2.4), with significant follow-on effects:
CAUTION: Review
the primary docu-
mentation in chapters 3
and 4 of the Mesh Point
functions you intend to
employ in advance of
determining your hard-
ware setup. Some hard-
ware features are
configurable; some soft-
ware functions have
specific hardware limi-
tations/requirements.
 At minimum, essential connectivity and security parameters
should preconfigured and tested on an outdoor Mesh Point
in advance of its deployment in the field.
 The LAN switch ports on an outdoor Mesh Point are
blocked by the required front-panel cover plate. The only
available network connections on an outdoor Mesh Point
are its front-panel WAN port and radio interfaces.
 The Mesh Point’s optional PSE function is exclusive to the
Mesh Point’s LAN switch ports. It has no application in an
outdoor Mesh Point.
 As described in Section 1.1, on ES520 version 1 hardware,
outdoor Mesh Points must be powered via their WAN port
using a compatible Power over Ethernet (PoE) source. On
ES520 version 2 hardware, outdoor Mesh Points can be
powered through their WAN ports or through their
weatherized, 4-pin, multi-range DC power inputs.
None of the above functional restrictions apply to Mesh Points
installed indoors.
2.1.3 Hardware Version Powering Options
The two ES520 hardware versions (Section 1.2.2) are both
equipped with a barrel-style 48V DC power input intended
exclusively for indoor use.
NOTE: ES520 pow-
er inputs are not
intended to provide re-
dundancy in either
hardware version.
Both hardware versions can optionally be powered through
their WAN ports by a remote Power over Ethernet (PoE)
midspan or endspan device. The WAN port PoE can be used to
power the Mesh Point indoors or, when the Mesh Point is fully
weatherized (Section 2.3), outdoors.
Included with both versions are one 70W universal AC-to-DC
power adapter module and one PoE midspan device.
The ES520 version 2 is additionally equipped with a
weathertight, 4-pin, multi-range DC input that can be used to
