GE-DS-82 and 82-PoE Ethernet Managed Switch User Manual 131
Power Over Ethernet
Providing up to 24 PoE, in-line power interface, the GE-DS-82-PoEPoE Switch can
easily build a power central-controlled IP phone system, IP Camera system, AP group
for the enterprise. For instance, 24 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.
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 5/9/12V 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.
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.
