GS-5220-48P4X Series
Redundant Ring, Fast Recovery for Critical Network Applications
The GS-5220-48P4X series supports redundant ring technology and features
strong, rapid self-recovery capability to prevent interruptions and external
intrusions. It incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring
Protection Switching) technology and Spanning Tree Protocol (802.1w RSTP)
into customer’s network to enhance system reliability and uptime in harsh
environments. In a certain simple Ring network, the recovery time could be less
than 10ms to quickly bring the network back to normal operation.
Layer 3 Routing Support
The GS-5220-48P4X series enables the administrator to conveniently boost
network efficiency by configuring Layer 3 IPv4/IPv6 VLAN static routing manually,
and the OSPFv2 (Open Shortest Path First) settings automatically. The OSPF is
an interior dynamic routing protocol for autonomous system based on link state.
The protocol creates a database for link state by exchanging link states among
Layer 3 switches, and then uses the Shortest Path First algorithm to generate a
route table based on that database.
Cybersecurity Network Solution to Minimize Security Risks
The cybersecurity feature included to protect the switch management in a mission-
critical network virtually needs no effort and cost to install. The SSH, TLS and SSL
protocolsareutilizedtoprovidestrongprotectionagainstadvancedthreats.The
network administrator can now construct highly-secure corporate networks with
considerably less time and effort than before.
Flexible and Extendable 10Gbps Ethernet Solution
Each of the SFP+ slot supports dual speed 10GBASE-SR/LR or 1000BASE-SX/
LX/BX, 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. With its 4-port, 10Gbps Ethernet link
capability, the GS-5220-48P4X series provides broad bandwidth and powerful
processing capacity.
Redundant AC/DC Power Supply to Ensure Continuous Operation
The GS-5220-48P4XR and GS-5220-48PL4XR are particularly equipped with one
100~240V AC power supply unit and one 36~60V DC power supply unit to provide
an enhanced reliable and scalable redundant power supply. The continuous power
systemisspecicallydesignedtofulllthedemandsofhigh-techfacilitiesrequiring
the highest power integrity. With the 36~60V DC power supply, it is able to act as
a telecom-level device that can be located in the electronic room.
