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.
Robust Layer2 Features

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.

1. Before we connect the switch to the other network device, we have to make sure both sides of the SFP transceivers are
with the same media type, for example: 1000BASE-SX to 1000BASE-SX, 1000BASE-LX to 1000BASE-LX.
2. Check whether the fiber-optic cable type matches with the SFP transceiver requirement.
To connect to 1000BASE-SX SFP transceiver, please use the multi-mode fiber cable with one side being the male
duplex LC connector type.
To connect to 1000BASE-LX SFP transceiver, please use the single-mode fiber cable with one side being the male
duplex LC connector type.
Connect the Fiber Cable
1. Insert the duplex LC connector into the SFP/SFP+ transceiver.
2. Connect the other end of the cable to a device with SFP/SFP+ transceiver installed.
3. Check the LNK/ACT LED of the SFP/SFP+ slot on the front of the Managed Switch. Ensure that the SFP/SFP+
transceiver is operating correctly.
4. Check the Link mode of the SFP/SFP+ port if the link fails. To function with some fiber-NICs or Media Converters, user
has to set the port Link mode to “10GForce”, “1000 Force” or “100 Force”.
Remove the Transceiver Module

interface.
2.3.1 Connecting Stacking Cable
Before attempting to connect stacking ports, verify that you have the required stack cables. T he follow ing cab les are used to
connect stack ed switches:
• CB-DASFP-0.5M: 10G SFP+ Directly-attached Copper Cable (0.5M in length)
• CB-DASFP-2M: 10G SFP+ Directly-attached Copper Cable (2M in length)
• MTB-LR: SFP+ Port 10GBASE-LR mini-GBIC Module (single-mode/1310nm/max. 10km).
• MTB-SR: SFP+ Port 10GBASE-SR mini-GBIC Module (multi-mode/850nm/max. 300m)
• Standard 10GBASE-LR/SR mini-GBIC SFP+ Module.
There are two high-performance SFP+ stacked ports on the rear pa nel for propr i et ary man agem ent stack.
Step 1: Plug one end of the cable into the “STX1” port and the other end into the ”STX2” port of the next device.
Step 2: Repeat the step for every device in the stack cluster, and then ending with the last switch.
Figure 2-23 Stacking Connection
Step 3: If you wish to implement stack redundancy, use the long stack cable to connect the stack port marked “STX1” on the
bottom switch to the port marked “STX2” on the top switch of the stack.
The stack port is for management and data packets to be transmitted between other SGS-5220
stackable switch series. The stack ports can’t be configured with Layer 2 features via
Step 4: Power up the stack switches.
User’s Manual of SGS-5220 Series

2.3.2 Management Stacking
The stack operation of the SGS Managed Switch supports Plug and Play Stacking connection and auto stack configuration.
Step 5: Once the stack starts operation, the Stack master will be automatically selected without any configuration. The Stack
master is indicated by a lit green “Master” LED on the front panel as Figure 2-24 shows.
Stack ID
Master LED
Figure 2-24 Stack Master with “Master” LED lit
Step 6: When an SGS Switch is added to the stack, a Switch ID is automatically assigned to the SGS Switch. T he autom atic
SID assignment can be modified by choosing a different Switch ID on the Stack Configuration page. This method
allows Switch IDs to be assigned so that it is easier for the user to remember the ID of each switch.
Step 7: Connect the RJ45 serial cable to the console port on the front of the stack master, and then login the SGS Switch to
start the switch management. O r you can use the PLANET Smart Discovery Utility to display the IP address of the
stack and Web login the stack with this IP address. The default IP address of the SGS Switch is 192.168.0.100.

3.3 Administration Console
The administration console is an interna l, chara cter -oriented, and command line user interface for performing system
administration such as displaying statistics or changing option settings. Using this method, you can view the administration
console from a terminal, personal computer, Apple Macintosh, or workstation connected to the Managed Switch's console
(serial) port.
Figure 3-1-1: Console Management
Direct Access
Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a
terminal-emulation program (such as HyperTerminal) to the Managed Switch console (serial) port. When using this
management method, a straight DB9 RS-232 cable is required to connect the switch to the PC. After making this connection,
configure the terminal-emulation program to use the following parameters:
The default parameters are:
115200 bps
8 data bits
No parity
1 stop bit
Figure 3-1-2: Terminal Parameter Settings
User’s Manual of SGS-5220 Series
44
You can change these settings, if desired, after you log on. This management method is often preferred because you can
remain connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port,
regardless of the interface through which the associated action was initiated. A Macintosh or PC attachment can use any
terminal-emulation progra m for connect ing to th e ter minal serial port . A workstation attachment under U NIX can use a n emu lator
such as TIP.
Remote Telnet
In Windows system, you may click “Start” and then choose “Acessories”and “Command Prompt”. Please input “telnet
192.168.0.100” and press “enter’ from your keyboard. You will see the following screen appears as Figure 3-2 shows.
User’s Manual of SGS-5220 Series

3.4 Web Management
The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the
network through a sta ndard brow ser such as M icros oft Intern et Ex plorer. After you set up yo ur IP addr ess for the sw itch, y ou can
access the Managed Switch's Web interface applications directly in your Web browser by entering the IP address of the
Managed Switch.
Figure 3-1-3: Web Management
You can then use your Web browser to list and manage the Managed Switch confi guration p aramet ers from one centr al locati on ,
just as if you were directly connected to the Managed Switch's console port. Web Management requires either Microsoft
Internet Explorer 8.0 or later, Safari or Mozilla Firefox 1.5 or later.
Figure 3-1-4: Web Main Screen of Managed Switch
User’s Manual of SGS-5220 Series
46
3.5 SNMP-based Network Management
You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMP Network
Manager, HP Openview Network Node Management (NNM) or What’s Up Gold. This management method requires the SNMP
agent on the switch and the SNMP Network Management Station to use the same community string. This management
method, in fact, uses two community strings: the get community string and the set community string.
If the SNMP Net-work management Station only knows the set community string, it can rea d and w rite to the M IBs. H owever, if it
only knows the get community string, it can only read MIBs. The default getting and setting community strings for the Managed
Switch is public.
Figure 3-1-5: SNMP Management
3.6 PLANET Smart Discovery Utility

4. WEB CONFIGURATION
This section introduces the configuration and functions of the Web-based management from Managed Switch.
About Web-based Management
The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the
network through a standard browser such as Microsoft Internet Explorer.
The Web-based Management supports Internet Explorer 7.0. It is based on Java Applets with an aim to reduce network
bandwidth consumption, enhance access speed and present an easy viewing screen.
By default, IE7
modify the browser setting to enable Java Applets to use network ports.
The Managed Switch can be configured through an Ether net connect ion, making sure the manager PC must be set on the same
IP subnet address with the Managed Switch.
For example, the default IP address of the Managed Switch is 192.168.0.100, then the manager PC should be set at
192.168.0.x (where x is a number between 1 and 254, except 100), and the default subnet mask is 255.255.255.0.
If you have changed the def aul t IP address of the Managed Switch to 192.168.1.1 with subnet mask 255.255.255.0 v ia console,
then the manager PC should be set at 192.168.1.x (where x is a number between 2 and 254) to do the related configuration on
manager PC.

done at less than one-half of the advertising duration. In the implementation, the
switch sends SSDP messages periodically at the interval one-half of the

4.2.9 DHCP Relay
Configure DHCP Relay on this page. DHCP Relay is used to forward and to transfer DHCP messages between the clients and
the server when they are not on the same subnet domain.
The DHCP option 82 enables a DHCP relay agent to insert specific information into a DHCP request packets when forwarding
client DHCP packets to a DHCP server and re move the specific information from a DH CP reply packets w hen f orwarding server
DHCP packets to a DHCP client. The DHCP server can use this information to implement IP address or other assignment
policies. Specifically the option works by setting two sub-options:
Circuit ID (option 1)
Remote ID (option2).
The Circuit ID sub-option is supposed to include information specific to which circuit the request came in on.
The Remote ID sub-option was designed to carry information relating to the remote host end of the circuit.
The definition of Circuit ID in the switch is 4 bytes in length and the format is "vlan_id" "module_id" "port_no". The parameter of
"vlan_id" is the first two bytes representing the VLAN ID. The parameter of "module_id" is the third byte for the module ID (in
standalone switch it always equals 0; in stac kable sw itch it means sw itch ID). T he p ara meter of "po rt_n o" is th e fourt h byte and it
means the port number.
The Remote ID is 6 bytes in length, an d the valu e equals the DHC P r elay agent ’s M AC address. The DHCP Relay Configuration

The switch stores its configuration in a number of text files in CLI format. The files are either virtual (RAM-based) or stored in
flash on the switch.
There are three system files:
• running-config: A virtual file that represents the currently active configuration on the switch. This file is volatile.
• startup-config: The startup configuration for the switch, read at boot time.
• default-config: A read-only file w ith v endor-speci fic co nfigurat i on. This file i s read when the system is restored to default
settings.
It is also possible to store up to two other files and apply them to running-config, thereby switching configuration.
Configuration Download page allows the download the running-config, startup-config and default-config on the switch. Please

If the destination is running-config, the file will be applied to the switch configuration. This can be done in two ways:
• Replace mode: The current configuration is fully replaced with the configuration in the uploaded file.
• Merge mode: The uploaded file is merged into running-config.
If the file system is full (i.e. contains the three system files mentioned above plus two other files), it is not possible to create new
files, but an existing file must be overwritten or another deleted first.

4.3 Simple Network Management Protoc ol
4.3.1 SNMP Overview
The Simple Netw ork M anagement Pro tocol (S NM P) is an a pplicat ion lay er proto col that f acil itate s th e ex change of ma nageme nt
information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite.
SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network
growth.
An SNMP-managed network consists of three key components: Network management stations (NMSs), SNMP agents,
Management information base (M IB) and network-management protocol：
■ Network management stations (NMSs)：Sometimes called consoles, these devices execute management applications
that monitor and control network elements. Physically, NMSs are usually engineering workstation-caliber computers with
fast CPUs, megapixel color displays, substantial memory, and abundant disk space. At least one NMS must be present in
each managed environment.
■ Agents：Agents are software modules that reside in network elements. They collect and store management information
such as the number of error packets received by a network element.
■ Management information base (MIB)：A MIB is a collection of managed objects residing in a virtual information store.
Collections of related managed objects are defined in specific MIB modules.
■ Network-management protocol：A management protocol is used to convey management information between agents
and NMSs. SNMP is the Internet community's de facto standard management protocol.
SNMP Operations
SNMP itself is a simple request/response protocol. NMSs can send multiple requests without receiving a response.
■ Get -- Allows the NMS to retrieve an object instance from the agent.
■ Set -- Allows the NMS to set values for object instances within an agent.
■ Trap -- Used by the agent to asynchronously inform the NMS of some event. The SNMPv2 trap message is designed to
replace the SNMPv1 trap message.
User’s Manual of SGS-5220 Series
82
SNMP community
An SNMP community is the group that devices and management stations running SNMP belong to. It helps define where
information is sent. The community name is used to identify the group. A SNMP device or agent may belong to more than one
SNMP community. It will not respond to requests fro m mana gemen t sta tion s that do n ot belo ng to on e of it s comm unitie s. S NMP
default communities are:
。 Write = private
。 Read = public

4.4.5 Port Mirror
Configure port Mirroring on this page. This function provide to monitoring network traffic that forwards a copy of each incoming
or outgoing packet fr om on e port of a network Switch to ano ther por t w here the packet can be studied. It enables the manager to
keep close track of switch performance and alter it if necessary.
• To debug network problems, selected traffic can be copied, or mirrored, to a mirror port where a frame analyzer can be
attached to analyze the frame flow.
• The Managed Switch can unobtrusively mirror traffic from any port to a monitor port. You can then attach a protocol
analyzer or RMON probe to this port to perform traffic analysis and verify connection integrity.
