GE-DS-242-PoE Managed Ethernet Switch User Manual 
Power Over Ethernet  
Providing up to 24 PoE, in-line power interface, the GE-DS-242-PoE PoE 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.
