Redundant AC/DC Power Supply to Ensure Continuous Operation
The GS-5220-20T4C4XR is particularly equipped with one 100~240V AC power supply
unit and one 36~60V DC power supply unit to provide an enhanced reliable and
scalableredundantpowersupply.Thecontinuouspowersystemisspecicallydesigned

36~60V DC power supply, the GS-5220-20T4C4XR is able to act as a telecom-level
device that can be located in the electronic room.
Solution for IPv6 Networking
By supporting IPv6/IPv4 dual stack and plenty of management functions with easy and
friendly-user interfaces, the GS-5220 series is the best choice for IP surveillance, VoIP
and wireless service providers to deploy the IPv6 network. It also helps the SMBs to
step in the IPv6 era with the lowest investment but not necessary to replace the network
facilities while the ISPs construct 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 switch series 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, flexible management
and simpler networking application.
Robust Layer2 Features
The GS-5220 series 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 SGS-5220
series allows the operation of a high-speed trunk combining multiple ports. It consists of
a maximum of 14 trunk groups with 8 ports for each group, and supports connection fail-
over as well.
