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 specied 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.

Intelligent Powered Device Alive-Check
The GS-4210-48P4S can be configured to monitor connected PD (Powered Device)
status in real time via ping action. Once the PD stops working and responding, the GS-
4210-48P4S will resume the PoE port power and bring the PD back to work. It will
greatly enhance the network reliability through the PoE port resetting the PD’s power
source and reducing administrator management burden.

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 dened 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.
