PoE Schedule for Energy Saving
Besides being used for IP surveillance, the GS-5220-8P2T2S is certainly applicable
to build any PoE network including VoIP and wireless LAN. Under the trend of energy
saving worldwide and contributing to the environmental protection on the Earth, the GS-
5220-8P2T2S 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 and enterprises save energy and budget.

GS-5220-8P2T2S
Solution for IPv6 Networking
With the support for IPv6/IPv4 protocol, and easy and friendly management interfaces, the GS-5220-8P2T2S is the best choice for IP surveillance, VoIP and
wireless service providers to connect with the IPv6 network. It also helps SMBs to step in the IPv6 era with the lowest investment and without having to
replace the network facilities even though ISPs establish the IPv6 FTTx edge network.

IPv4 and IPv6 VLAN Routing for Secure and Flexible Management
To help customers stay on top of their businesses, the GS-5220-8P2T2S not only provides ultra high transmission performance and excellent layer 2
technologies, but also offers IPv4/IPv6 VLAN routing feature which allows to crossover different VLANs and different IP addresses for the purpose of having a
highly-secure, exible management and simpler networking application.

Robust Layer2 Features
The GS-5220-8P2T2S can be programmed for advanced switch management function, such as dynamic port link aggregation, Q-in-Q VLAN, Multiple
Spanning Tree Protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD snooping. The GS-5220-8P2T2S allows the operation of a high-speed
trunk combining multiple ports. Supporting 6 trunk groups, it enables a maximum of up to 8 ports per trunk and supports connection fail-over as well.
Powerful Security
The SGS-5220-8P2T2S offers comprehensive layer 2 to layer 4 access control list (ACL) for enforcing security to the edge. It can be used to restrict 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-5220-8P2T2S also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and
discard ARP packets with invalid MAC address. The network administrator can now build highly-secure corporate networks with considerably less time and
effort than before.
User-friendly Secure Management
For efcient management, the GS-5220-8P2T2S is equipped with console, web and SNMP management interfaces. With the built-in web-based management
interface, theGS-5220-8P2T2S offers an easy-to-use, platform independent management and configuration facility. The GS-5220-8P2T2S supports SNMP
and it can be managed via any management software based on the standard SNMP v1 and v2 protocols. For reducing product learning time, the GS-5220-
8P2T2S offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command from these switches. Moreover, the GS-
5220-8P2T2S offers remote secure management by supporting SSH, SSL and SNMPv3 connection which can encrypt the packet content at each session.

Flexible and Extendable Solution
The 2 mini-GBIC SFP slots built in the GS-5220-8P2T2S support dual speed as it features 100BASE-FX and 1000BASE-SX/LX SFP (Small Form-factor
Pluggable) ber-optic modules. Now the administrator can exibly choose the suitable SFP transceiver according to not only the transmission distance, but
also the transmission speed required. The distance can be extended from 550 meters to 2km (multi-mode ber) and up to 10/20/30/40/50/70/120 kilometers
(single-mode ber or WDM ber). They are well suited for applications within the enterprise data centers and distributions.
Intelligent SFP Diagnosis Mechanism
The GS-5220-8P2T2S supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters
of the SFP transceivers, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
Applications
Layer 2+ VLAN Static Routing and PoE Application
With the built-in robust IPv4/IPv6 Layer 3 traffic routing protocols, the GS-5220-8P2T2S ensures reliable routing between VLANs and network segments.
The routing protocols can be applied by VLAN interface with up to 32 routing entries. The GS-5220-8P2T2S is certainly a cost-effective and ideal solution for
enterprises.
Providing up to 8 Gigabit High-power PoE ports and in-line power interface, the GS-5220-8P2T2S High-power PoE Switch can easily build a centrally-
controlled power network shared by wireless Gigabit AP, IP phone system, or mega-pixel IP camera system group for the enterprises.
