1.2 Product Description
Amazing Ultra PoE Managed Switch with Advanced L2+/L4 Switching and Security
PLANET GS-5220 Ultra PoE & PoE+ Series is a Cost-optimized, 1U, Gigabit Ultra PoE Managed Switch featuring PLANET
intelligent PoE functions to improve the availability of critical business applications. It provides IPv6/IPv4 dual stack
management and built-in L2+/L4 Gigabit switching engine along with 16/24 10/100/1000BASE-T ports featuring 36/75-watt
PoE,4 Gigabit TP/SFP combo ports and 2/4 additional 10Gigabit SFP+ ports. With a total power budget of up to 400/600
watts for different kinds of PoE applications, the GS-5220 Ultra PoE & PoE+ Series provides a quick, safe and cost-effective
ultra PoE network solution for small businesses and enterprises.
Convenient and Smart ONVIF Devices with Detection Feature
PLANET has newly developed an awesome feature -- ONVIF Support -- which is specifically designed for co-operating with
Video IP surveillances. From the GS-5220 Ultra PoE & PoE+ Series GUI, clients just need one click to search and show all of
the ONVIF devices via network application. In addition, clients can upload floor images into switch and allows for deploying
location of surveillance devices for easier inspection and planning. Moreover, clients can get real-time surveillance’s information
and online/offline status, and it also allows PoE reboot control from GUI.
75 Watts of Power over 4-pair UTP (For Ultra PoE Switches)
The GS-5220 Ultra PoE Series’ ultra PoE solution adopts the IEEE 802.3at/af standard. Instead of delivering power over 2-pair
twisted UTP – be it end-span (Pins 1,2,3 and 6) or mid-span (Pins 4,5,7 and 8), it provides the capability to source up to 75 watts
of power by using all the four pairs of standard Cat.5e/6 Ethernet cabling. In the new 4-pair system, two PSE controllers will be
used to power both the data pairs and the spare pairs. It can offer more PoE applications, such as:
■PoE PTZ speed dome
■ Any network device that needs higher PoE power to work normally
■Thin-client
■AIO (All-in-One) touch PC
■ Remote digital signage display

Built-in Unique PoE Functions for Powered Devices Management
As it is the managed PoE switch for surveillance, wireless and VoIP networks, the GS-5220 Ultra PoE & PoE+ Series features
the following special PoE management functions:
PD alive check
Scheduled power recycling
PoE schedule
PoE usage monitoring
Intelligent Powered Device Alive Check
The GS-5220 Ultra PoE & PoE+ Series can be configured to monitor connected PD (powered device) status in real time via ping
action. Once the PD stops working and responding, the GS-5220 Ultra PoE & PoE+ Series 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 reducing administrator management burden.
Scheduled Power Recycling
The GS-5220 Ultra PoE & PoE+ Series allows each of the connected PoE IP cameras or PoE wireless access points to reboot
at a specified time each week. Therefore, it will reduce the chance of IP camera or AP crash resulting from buffer overflow.

PoE Schedule for Energy Saving
Under the trend of energy saving worldwide and contributing to environmental protection, the GS-5220 Ultra PoE & PoE+ Series
can effectively control the power supply besides its capability of giving high watts power. The “PoE schedule” function helps
you to enable or disable PoE power feeding for each PoE port during specified time intervals and it is a powerful function to help
SMBs or enterprises save power and money. It also increases security by powering off PDs that should not be in use during
non-business hours.
PoE Usage Monitoring
Via the power usage chart in the web management interface, the GS-5220 Ultra PoE & PoE+ Series enables the administrator
to monitor the status of the power usage of the connected PDs in real time. Thus, it greatly enhances the management
efficiency of the facilities.
Cost-effective 10Gbps Uplink Capacity
10G Ethernet is a big leap in the evolution of Ethernet. The four 10G SFP+ slots of the GS-5220 Ultra PoE & PoE+ Series
support dual-speed 10GBASE-SR/LR or 1000BASE-SX/LX, meaning the administrator now can flexibly choose the suitable
SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network
efficiently. They greatly support SMB network to achieve the maximum performance of 10Gbps in a cost-effective way because
the 10GbE interface usually could be available in Layer 3 Switch but Layer 3 Switch could be too expensive to SMBs.
