Managed Switch PLANET GS-4210-24T4SR 24-Port Gigabit Ethernet L2/L4

The PLANET GS-4210-24T4SR is a 24-port managed Gigabit Ethernet switch designed for SMBs and rack-mount deployments. It provides Layer 2/Layer 4 switching and security functions, dual-stack IPv4/IPv6 management, four SFP uplink interfaces, and a redundant AC plus 36–72 V DC power supply option to ensure continuous operation in demanding environments. The fanless design and energy-saving features deliver quiet, reliable performance for office and data distribution networks.

Advantages

The switch offers advanced L2/L4 switching capabilities, robust QoS and traffic control, and comprehensive security features including ACLs, 802.1X, DHCP snooping, IP source guard and dynamic ARP inspection. Redundant AC/DC power support, SFP fiber uplinks for long-distance extension, and IPv4/IPv6 dual-stack management provide operational flexibility and future-proofing. Its fanless construction reduces noise and power consumption while maintaining stable performance.

Suitable for

• Small and medium business network aggregation and edge switching
• Rack-mounted office or telecom equipment rooms requiring DC-backed power
• Environments needing secure access control and traffic prioritization (VoIP, video)
• Long-distance uplink to backbone switches or monitoring centers via SFP fiber

• Weight: 2.1 kg
• Networking standards: Relevant IEEE 802.1 and 802.3 family standards

How to use

Install the switch in a standard 1U rack space and connect the AC and DC power inputs if redundant power is required. Use the RJ-45 Gigabit ports to connect servers, desktops and access devices and populate the SFP slots with appropriate fiber transceivers for uplinks. Access management via the built-in web interface for graphical configuration, or use Telnet/console and SNMP for scriptable and centralized management. Configure VLANs, link aggregation, QoS and security policies according to network design, and enable SSH/TLS or SNMPv3 for secure remote administration.

Recommendations

For reliable operation, deploy appropriate SFP modules that match your fiber type and distance, enable redundant power when continuous uptime is required, and apply ACLs, 802.1X and DHCP snooping to enforce access control. Use QoS settings to prioritize voice and video traffic and monitor the switch via SNMP for proactive maintenance.
