Frequency Interference Statements
This equipment generates, uses, and can radiate radio-frequency energy,
and if not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio
communication. It has been tested and found to comply with the limits for
a Class A computing device in accordance with the specifications in
Subpart B of Part 15 of FCC rules, which are designed to provide
reasonable protection against such interference when the equipment is
operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the user at
his own expense will be required to take whatever measures may be
necessary to correct the interference.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate
the equipment.
This digital apparatus does not exceed the Class A limits for radio noise
emission from digital apparatus set out in the Radio Interference
Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de

2.2 Product description
LPH240A Industrial PoE switch is a reliable and premium-rated
Industrial Ethernet product Switch. Strictly designed to be IEEE 802.3af
compatible, the 4-port PoE Edge switch, not only provides PoE options
on port #3, 4, 5 and 6 but is also equipped with a LLL (Link-Loss-Learn)
feature on port #1 and 2 for use in self-healing redundant LAN structures.
Enclosed in a rugged enclosure, designed and developed with premium-
grade extended temperature components, Industrial-rated LPH240A PoE
Edge switches are suitable for use in sheltered outdoor locations and
temperature-uncontrolled environments with a temperature rating of
-40°C to 75°C.
The LPH240A PoE Power source Edge Switch combines
standard 802.3af Power over Ethernet (PoE) with a small heavy duty 4-
port PoE ports and 2 100Mb Fiber or 10/100 RJ-45 ports, as per the user
requirement. Using an external -48vdc power source, all four of the
LPH240A’s Ethernet ports can provide Power as well as 10/100 Mb data
transmission over the interconnecting Ethernet cables. So a single
Ethernet twisted pair (RJ-45) cable will be able to transmit voice, data,
and power from the attached devices.
The LPH240A Edge switches are Power Sourcing Equipment
(PSE), and are fully compatible with Powered Devices (PD) (e.g wireless
access points, IP phones) that comply with the IEEE 802.3af PoE
standard.
NOTE: Only PoE powered devices complying with IEEE 802.3af are
recommended to work successfully with LPH240A power source PoE
switches. NON-802.3af compliant PD devices might have
COMPATIBILITY issues, and are not being supported with LPH240A
PoE switches.
