Power over Ethernet switches
Power and data transferred in parallel
Power over Ethernet (PoE) describes a process where power
can be supplied to a network-compatible device over the
8-wire Ethernet cable. In a narrower sense, PoE today means
the IEEE 802.3af (DTE Power over MDI) standard which was
adopted in June 2003.
The main advantage of Power over Ethernet is that you do
not require a separate power supply cable and so can install
Ethernet devices in hard-to-reach places or in areas where
there is not sufcient room for many cables. This means
that you can save some signicant installation costs, and
that you can also integrate the power supply into a central
uninterruptible power supply (UPS) to improve the reliability
of the connected devices.
PoE is used by network devices that need small amounts
of power. It is typically used for IP telephones, network
cameras, operating panels or wireless communications
devices such as WLAN access points.
Weidmüller PoE switches support the IEE 802.3at standard
(also known as PoE+) and can therefore supply end devices
with up to 30 W per PoE port.
Weidmüller PoE switches also offer further advantages by
their simple power supply needs. They do not require an
additional 48 V supply in addition to the standard 24 V
supply.
