1.2 Product Description
High-Density, Resilient Deployment Switch Solution for Gigabit Networking of Enterprise, Campus and Data Center
For the growing Gigabit network and IoT (Int erne t of T hing s) dema nd, P LAN ET has launched a new-generation Stackable
Gigabit Switch solution, the SGS-5220 switch series, to meet the needs of enterprises, telecoms and campuses for a
large-scale network deployme nt. The SGS-5220 switch series is Layer 2+ Stackable Managed Gigabit Switch, which supports
both IPv4 and IP v6 protocols and hardware Layer 3 static routing capability, and provides 24 10/100/1000Mbps Gigabit
Ethernet ports, 4 shared Gig abit SFP slots, 2 10G SFP+ uplink slots and another 2 dedicated 10G SFP+ stacked
interfaces for stacking with the series of switches. Up to 16 unit s, 38 4 G iga bit E t hern et ports and 32 10Gbps SFP+ slots can b e
managed by a stacking group and you can add ports and functionality as needed.
Efficient Single IP Managem ent
The SGS-5220 series applies the adv ant age o f the sta cking t echnology to managi ng the sta ck group w ith one single I P addres s,
which helps network managers to easily manage a stack of switches instead of connecting and setting each unit one by one.
The stacking technology also enable s the chassi s-based sw itches to b e integra ted into the SGS-5220 Managed Switch series at
an inexpensive cost.
Highly-reliable Stacking Ability
Through its up to 40Gbps, bi-directional high bandwidth tunnel and stacking technology, the SGS-5220 switch series gives the
enterprises, service providers and telecoms flexible control over port density, uplinks and switch stack performance. The stack
redundancy of the SGS-5220 sw itch series ensures that data integrity is retained even if one switch in the stack fails. You can
even hot-swap switches without disrupting the network, which greatly simplifies the tasks of upgrading the LAN for catering to
increasing bandwidth demand s.
User’s Manual of SGS-5220 Series

Cost-effective 10Gbps Uplink Capacity
10G Ethernet is a big leap in the evolution of Ethernet. The two 10G SFP+ slot of the SGS-5220 switch series supports
Dual-speed, 10GBASE-SR/LR or 1000BASE-SX/LX, 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. They greatly support SMB network to achieve 10Gbps high performance in a cost-effective way because 10GbE
interface usually could be available in Layer 3 Switch but Layer 3 Switch could be too expensive to SMBs.
Solution for IPv6 Networking
By supporting IPv6/IPv4 dual stack and plenty of management functions with easy and friendly management interfaces, the
SGS-5220 series is the best choice for IP surveillance, VoIP and wireless service providers to connect with the IPv6 network. It
also helps the SMB to step in the IPv6 era with the lowest investment but not necessary to replace the network facilities while
the ISP constructs 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 SGS-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 secured, flexible management and simpler
networking application.

1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber-optic modules. Now the administrator can flexibly 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 fiber) and up to above 10/20/30/40/50/70/120 kilometers
(single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.
Intelligent SFP Diagnosis Mechanism
The SGS-5220 switch series supports SFP-DDM (Digit al Diagnostic Monitor) fun ction that greatly help s netw ork admini str ator
to easily monitor real-t ime p arameters of the SFP and SFP+ transceiv er s, such as optical output power, optical input power,
temperature, laser bias current, and transceiver supply voltage.
Centralized Power Management for Gigabit Ethernet PoE Networking
To fulfill the needs of higher power required PoE network applications with Gigabit speed transmission, the SGS-5220-24P2X
features high-performance Gigabit IEEE 802.3af PoE (up to 15.4 watts) and IEEE 802.3at PoE+ (up to 30 watts) on all ports. It
perfectly meets the power requirements of PoE VoIP phone and all kinds of PoE IP cameras such as IR, PTZ, speed dome
cameras or even box type IP cameras with built-in fan and heater for high power consumption.
The SGS-5220-24P2X’s PoE capabilities also help to reduce deployment costs for network devices as a result of freeing from
restrictions of power outlet locations. Power and data switching are integrated into one unit, delivered over a single cable and
managed centrally. It thus eliminates cost for additional AC wiring and reduces installation time.
