75 Watts of Power over 4-pair UTP
The GS-5220 LCD series with LCD Touch Screen that features ultra PoE 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), they provide 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. They 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

Scheduled Power Recycling
The GS-5220 LCD series with LCD Touch Screen allows each of the connected PoE IP cameras or PoE wireless access points
to reboot at a specified time each week. Therefore, they 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 LCD series with LCD
Touch Screen can effectively control the power supply besides their 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.

aggregation, Q-in-Q VLAN, Multiple Spanning Tree Protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD
snooping. The SGS-5220 LCD series allows the operation of a high-speed trunk combining with multiple ports.
Powerful Security
The GS-5220 LCD series offers a comprehensive Layer 2 to Layer 4 access control list (ACL) for enforcing security to the
edge. It can be used to restrict to network access by denying packets based on source and destination IP address, TCP/UDP
port number or defined typical network applications. Its protection mechanism also comprises 802.1x Port-based and
MAC-based user and device authentication. With the private VLAN function, communication between edge ports can be
prevented to ensure user privacy.
Enhanced Security and Traffic Control
The GS-5220 LCD series also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to
prevent IP snooping from attack and discardARP packets with invalid MAC address. The network administrator can now
construct highly-secure corporate networks with considerably less time and effort than before.
User-friendly Secure Management
For efficient management, the GS-5220 LCD series is equipped with console, web and SNMP management interfaces. With the
built-in web-based management interface, the GS-5220 LCD series offers an easy-to-use, platform independent management
and configuration facility. The GS-5220 LCD series supports SNMP and it can be managed via any management software
based on the standard SNMP v1 or v2 Protocol. For reducing product learning time, the GS-5220 LCD series offers Cisco-like
command via Telnet or console port and customer doesn’t need to learn new command from these switches. Moreover, the
GS-5220 LCD series offers the remotely secure management by supporting SSH, SSL and SNMP v3 connection where the
packet content can be encrypted at each session.
