5.9 Power over Ethernet
This segment shows the Power over Ethernet function (Only for ISW-1022MPT).
Providing up to 8 PoE, in-line power interface, the ISW-1022MPT Industrial PoE Switch can easily build a power
central-controlled IP phone system, IP Camera system, AP group for the enterprise. For instance, 8 camera / AP can be
easily installed around the corner in the company for surveillance demands or build a wireless roaming environment in the
office. Without the power-socket limitation, the PoE Switch makes the installation of cameras or WLAN AP more easily
and efficiently.
5.9.1 Power over Ethernet Powered Device
3~5 watts
Voice over IP phones
Enterprise can install POE VoIP Phone, ATA and other
Ethernet/non-Ethernet end-devices to the central where UPS is installed
for un-interrupt power system and power control system.
6~12 watts
Wireless LAN Access Points
Museum, Sightseeing, Airport, Hotel, Campus, Factory, Warehouse
can install the Access Point any where with no hesitation
10~12 watts
IP Surveillance
Enterprise, Museum, Campus, Hospital, Bank, can install IP Camera
without limits of install location – no need electrician to install AC
sockets.
3~12 watts
PoE Splitter
PoE Splitter split the PoE 48V DC over the Ethernet cable into 5/12V DC
power output. It frees the device deployment from restrictions due to
power outlet locations, which eliminate the costs for additional AC wiring
and reduces the installation time.
5.9.2 Power Management:
In a power over Ethernet system, operating power is applied from a power source (PSU-power supply unit) over the LAN
infrastructure to powered devices (PDs), which are connected to ports. Under some conditions, the total output power
required by PDs can exceed the maximum available power provided by the PSU. The system may a prior be planed with a
PSU capable of supplying less power than the total potential power consumption of all the PoE ports in the system. In
order to maintain the majority of ports active, power management is implemented.
The PSU input power consumption is monitored by measuring voltage and current .The input power consumption is equal
to the system’s aggregated power consumption .The power management concept allows all ports to be active and
