protection of enclosed equipment from foreign bodies. The second defines the protection level that the
enclosure enjoys from various forms of moisture (drips, sprays, submersion etc.).
IP66
Enclosure = IP rated as “dust tight” and protected against heavy seas or powerful jets of water. These
enclosures are constructed for indoor or outdoor use to provide a degree of protection to personnel against
incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet,
snow, windblown dust, splashing water, and hose-directed water; and that will be undamaged by the external
formation of ice on the enclosure. See

for more information. See NEMA Standards Publication 250-2003, “Enclosures for Electrical Equipment (1000
Volts Maximum)”. This Standards Publication as well as all other NEMA publications are available from IHS @

Midspan
: PSE type located between a non-PoE switch and a PD. Also called a PoE injector.
NDEF
: (NFC Data Exchange Format) is a light-weight binary format, used to encapsulate typed data. It is specified
by the NFC Forum, for transmission and storage with NFC, however it is transport agnostic. NDEF defines
messages and records. An NDEF Record contains typed data, such as MIME-type media, a URI, or a custom
application payload. An NDEF Message is a container for one or more NDEF Records.
NEMA 4X
: In Non-Hazardous Locations, the specific enclosure Type, its applications, and the environmental
conditions it is designed to protect against, when completely and properly installed. Type 4X Enclosures
constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to
hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid
foreign objects (windblown dust); to provide a degree of protection with respect to harmful effects on the
equipment due to the ingress of water (rain, sleet, snow, splashing water, and hose directed water); that
provides an additional level of protection against corrosion; and that will be undamaged by the external
formation of ice on the enclosure.
NFC
(Near Field Communication) is a form of contactless communication between devices like smartphones or
tablets. Contactless communication allows a user to wave the smartphone over a NFC compatible device to send
information without needing to touch the devices together or go through multiple steps setting up a connection.
NFC technology lets smartphones and other enabled devices communicate with other devices with a NFC tag.
is devoted to educating individuals, small businesses, and large companies alike on
the merits of near field communication. NFC establishes a secure channel and uses encryption for sending
sensitive information. Recommend users have anti-virus software and passwords on their devices in case they
are lost or stolen. NFC state can be disabled via the CLI or the Web UI.

PD
(Powered Device): A device that receives power from a PSE over the twisted-pair copper cabling channel
(e.g., an IP phone, WAP, or IP camera).
PSE
(Power Sourcing Equipment): A device that delivers (sources) power over a twisted-pair copper cabling
channel to a powered device (e.g., a switch).
