secured corporate networks with considerably less time and effort than before.
User-friendly Secure Management
For efficient management, the SGS-5220 series managed switch series is equipped with console, web and SNMP management
interfaces. With the built-in web-based management interface, the SGS-5220 series offers an easy-to-use, platform
independent management and configuration facility. The SGS-5220 series supports SNMP and it can be managed via any
management software based on standard of SNMP v1 and v2 protocol. For reducing product learning time, the SGS-5220
series offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command from these
switches. Moreover, the SGS-5220 series offers remote secure management by supporting SSH, SSL and SNMPv3 connection
which can be encrypted the packet content at each session.
Flexible and Extendable Solution
The 4 mini-GBIC SFP slots built in the SGS-5220 switch series support dual speed as it features 100Base-FX and
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 (Digital Diagnostic Monitor) function that greatly helps network administrator
to easily monitor real-time parameters of the SFP and SFP+ transceivers, 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 requirement 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.
Built-in Unique PoE Functions for Surveillance Management
As a managed PoE Switch for surveillance network, the SGS-5220-24P2X features intelligent PoE Management functions:
 Scheduled Power Recycling
 SMTP/SNMP Trap Event Alert
 PoE Schedule
Scheduled Power Recycling
The SGS-5220-24P2X allows each of the connected PD (Powered Device) to reboot in a specific time each week. Therefore, it
will reduce the chance of PD (Powered Device) crash resulting from buffer overflow.
