Flexible and Extendable 10Gbps Ethernet Solution
10Gbps Ethernet is a big leap in the evolution of Ethernet. Each of the SFP+ ports
supports dual speed and 10GBASE-SR/LR, meaning the administrator now can
exiblychoosethesuitableSFP+transceiveraccordingtothetransmissiondistance
orthetransmissionspeedrequiredtoextendthenetworkefciently.Withits4-port,
10Gbps Ethernet link capability, the GS-5220 provides broad bandwidth and
powerful processing capacity.
Centralized Power Management for Gigabit Ethernet PoE Networking
To fulfill the needs of higher power required PoE network applications with Gigabit
speed transmission, the GS-5220 features IEEE 802.3at PoE+ that combines up
to 36 watts of power output and data per port over one Cat5E/6 Ethernet cable. It
is designed specifically to meet the demand of higher power consuming network
PD (powered device) such as IR, PTZ, speed dome cameras or even box-type IP
camera with a built-in fan and heater. Compliant with both 802.3at and 802.3af, it
allowsmoreexibilityinpowerrequirementforavarietyofPDs.
Built-in Unique PoE Functions for Surveillance Management
As a managed PoE Switch for surveillance network, the GS-5220 features four
special PoE management functions:
■PDalivecheck
■Scheduledpowerrecycling
■PoEschedule
■PoEusagemonitoring
Intelligent Powered Device Alive Check
The GS-5220 can be configured to monitor connected PD status in real time via
ping action. Once the PD stops working and has no response, the GS-5220 will
resume the PoE port power and bring the PD back to work. It will greatly enhance
the network reliability through the PoE port resetting the PD’s power source and
reduces administrator management burden.
