ISSUE 1
IEEE has recently voted to approve and ratify the 802.3at as the new standa=
rd for Power-over-Ethernet. This motion increases the existing .af standard=
of 15.4W to 30W to support a wider array of PoE applications including VoI=
P Phones with streaming video, PTZ Cameras with heaters, and security funct=
ions including access control. [1]For more information...
Phihong=E2=80=99s Power-over-Ethernet switch extends PoE and Ethernet up t=
o 200
meters+ and can power four IP cameras from a single Cat5 cable.
Designated the POE60S-4AF, the 10/100baseT switch extends the capability
of Ethernet and PoE from a current limit 100-meter reach to double the
distance. The PoE switch can operate under temperatures from 0=C2=BA to 55=
=C2=BAC.
It works with either an Ultra PoE midspan (providing IEEE802.3af
outputs) or an AC adapter, and is UNH-tested. [2]Read more=E2=80=A6

[7]Power, data carried over single Ethernet cable
Phihong=E2=80=99s full power-, no limits-midspans provide full-power on e=
very
port. This advanced technology is the most cost-effective solution when
you have to expand your network. Our midspans support 10/100/1,000
(gigabit) Ethernet. Designed around an open silicon platform and
featuring USB connectivity for the management console, our midspans are
designed and tested in the USA for greater focus on the North American
PoE market. Today=E2=80=99s midspans can deliver the necessary power to cu=
rrent
and future generations of VoIP phones, wireless LAN access points,
remote IP security cameras, access control devices, RFID readers, motion
detectors, keypads, building automation controls and other emerging
products. [8]Read more=E2=80=A6
Introducing 95 Watts Per Port, Mega PoE Midspans
Phihong has developed a Power-over-Ethernet midspan product line that
offers the highest power per port available on the market. Available in
2- and 4-port versions, the POE240U-2MP and POE576U-4MP
Gigabit-compatible Mega PoE midspans provide up to 95W of power per
port, more than any other midspan or PoE-enabled switch, making them
ideal for high-power applications such as computer workstations, LCD
display panels, and wireless access point (WAP) arrays. [9]Read more=E2=80=

=E2=80=A2 Splitters and midspans are available to power camera PTZ motors=
and
heater devices.
=E2=80=A2 With a UPS backup for the Security network, the entire camera ne=
twork
can continue operation during a power outage.
=E2=80=A2 With full power, no limit midspans, you can efficiently and co=
st-
effectively supply power to cameras, sensors, scanners and alarms
without the need to install power outlets and electrical cabling.
