PoE Schedule for Energy Saving
Under the trend of energy saving worldwide and contributing to environmental protection,
the GS-4210-48P4S can effectively control the power supply besides its capability of
giving high watts power. The “PoE schedule” function helps you to enable or disable
PoE power feeding for each PoE port during specied time intervals and it is a powerful
function to help SMBs or enterprises save power and money. It also increases security
by powering off PDs that should not be in use during non-business hours.

GS-4210-48P4S
Environment-friendly, Smart Fan Design for Silent Operation
The GS-4210-48P4S features a low noise design and an effective ventilation system. It
supports the smart fan technology that automatically controls the speed of the built-in
fan to reduce noise and maintain the temperature of the PoE switch for optimal power
output capability. The GS-4210-48P4S is able to operate reliably, stably and quietly in
any environment without affecting its performance.
IPv6/IPv4 Dual Stack Management
Supporting both IPv6 and IPv4 protocols, the GS-4210-48P4S helps the SMBs to step in
the IPv6 era with the lowest investment as its network facilities need not be replaced or
overhauled if the IPv6 network is set up.
Robust Layer 2 Features
The GS-4210-48P4S can be programmed for advanced switch management functions
such as dynamic port link aggregation, 802.1Q VLAN and Q-in-Q VLAN, Multiple
Spanning Tree protocol (MSTP), loop and BPDU guard, IGMP snooping, and MLD
snooping. Via the link aggregation, the GS-4210-48P4S allows the operation of a
high-speed trunk to combine with multiple ports, and supports fail-over as well. Also,
the Link Layer Discovery Protocol (LLDP) is the Layer 2 protocol included to help
discover basic information about neighboring devices on the local broadcast domain.

Powerful Security
PLANET GS-4210-48P4S offers comprehensive IPv4/IPv6 Layer 2 to Layer 4 Access
Control List (ACL) for enforcing security to the edge. It can be used to restrict network
access by denying packets based on source and destination IP address, TCP/UDP ports
or dened typical network applications. Its protection mechanism also comprises 802.1X
port-based user and device authentication, which can be deployed with RADIUS to
ensure the port level security and block illegal users. With the protected port function,
communication between edge ports can be prevented to guarantee user privacy.
Furthermore, port security function allows to limit the number of network devices on a
given port.
Advanced Network Security
The GS-4210-48P4S also provides DHCP snooping, IP source guard and dynamic
ARP inspection functions to prevent IP snooping from attack and discard ARP packets
with invalid MAC address. The network administrators can now construct highly-secure
corporate networks with considerably less time and effort than before.

GS-4210-48P4S
Friendly and Secure Management
For efcient management, the GS-4210-48P4S is equipped with web, Telnet and SNMP management interfaces. With the built-in web-based management
interface, the GS-4210-48P4S offers an easy-to-use, platform-independent management and configuration facility. By supporting the standard SNMP, the
switch can be managed via any standard management software. For text-based management, the switch can be accessed via Telnet. Moreover, the GS-
4210-48P4S offers secure remote management by supporting SSH, SSL and SNMP v3 connections which encrypt the packet content at each session.
Flexibility and Long-distance Extension Solution
The four mini-GBIC slots built in the GS-4210-48P4S support SFP auto-detection and dual speed as it features 100BASE-FX and 1000BASE-SX/LX SFP
(Small Form-factor Pluggable) ber transceivers to uplink to backbone switch and monitoring center in long distance. The distance can be extended from 550
meters to 2 kilometers (multi-mode ber) and up to 10/20/30/40/50/70/120 kilometers (single-mode ber or WDM ber). They are well suited for applications
within the enterprise data centers and distributions.
Intelligent SFP Diagnosis Mechanism
The GS-4210-48P4S supports SFP-DDM (Digital Diagnostic Monitor) function that can easily monitor real-time parameters of the SFP for network
administrator, such as optical output power, optical input power, temperature, laser bias current and transceiver supply voltage.
Applications
High Density of IP Surveillance Network
Providing up to 48 PoE+, in-line power interfaces and 4 100/1000BASE-X SFP interfaces, the GS-4210-48P4S can easily build an IP camera system
where power can be centrally controlled. The GS-4210-48P4S can work with 8/16/32-channel NVR and surveillance software to perform comprehensive
security monitoring. For instance, one GS-4210-48P4S can be combined with one 32-channel NVR and one 8-channel NVR, which feature real-time video
and audio, live viewing, and playback. Each of its PoE ports can be linked with a PoE IP camera in order for the administrators to centrally and efciently
manage the surveillance system in one site. Moreover, its 4 100/1000BASE-X SFP interfaces also provide flexible fiber connection for uplink to public
server groups.
