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 triple speed 10GBASE-SR/LR, 2500BASE-X 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efciently.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-5220-48PL4XR 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.
