Cost Effective, Reliable, Scalable and Secure Switch Solution for SMB NetworksTo increase the distance/speed of your network server and backbone connections. Gigabit High-Speed ConnectionComplies with IEEE802.3/802.3u/802.3ab/802.3z Gigabit Ethernet Standards, the GS-5424PLC features 24 Gigabit Ethernet ports for high-speed, large file transfer and 4 SFP slots for long range optical fiber Gigabit Ethernet connections. 802.3at PoE with Auto Detection & Power Backfeed ProtectionThe GS-5424PLC features 24 IEEE 802.3at Power over Ethernet (PoE+) ports which supply up to 30W of electricity per port and has a total power supply of 450W to power any 802.3at or 802.3af compliant power device. With PoE detection capability, the GS-5424PLC is able to verify whether the connected device is IEEE 802.3at or 802.3af compliant. If a PoE device is not detected, only network data will be transmitted. Moreover, with the PoE power backfeed protection from the passive PoE injectors, the GS-5424PLC is able to avoid damaging the PoE ports. PoE for Easy Installation and Better Cost EfficiencyPower over Ethernet technology enables the Ethernet cable to carry both data and power, reducing cable installation and eliminating the need for extension cords or electrical outlets on the walls and ceiling. The GS-5424PLC can effectively lower installation costs and simplify deployment effort. The GS-5424PLC can be used with different PoE products such as access points, IP cameras or VoIP devices and is an effective solution for network environments where power outlets are difficult to access. PoE Powered Device Alive CheckFeaturing PoE Powered Device (PD) alive check, the switch can be configured to monitor real-time status of connected PDs by ping action (sending alive-checking packets). If a PD fails to response, the GS-5424PLC PoE Switch will reboot the PD, which enhances the reliability of the network and reduces administrator management burden.Long Range PoE Distance Extension, up to 200 MetersThe long range mode provides extended power and data delivery distance to up to 200 meters while general Ethernet switches have a distance restriction of 100 meters. The long range mode operates on a per-port basis at 10Mbps full-duplex operation, ideal for devices such as IP cameras, IP phones and PoE-enabled IoT devices at a remote location. Dual FirmwareThe dual firmware feature allows switches to have two firmware in storage. You can denote one of these firmware as the active one and the other firmware as the backup. If the active firmware faces problems, you can activate the backup firmware right away to reduce down time. Voice VLANVoice VLAN is a special function of GS-5424PLC switch which allows network administrator to easily prioritize IP voice traffic from IP phone through the access port of switch to enhance VoIP service. Voice VLAN also provides QoS to VoIP, ensuring that the sound quality of an IP phone does not deteriorate when the IP voice traffic is sent unevenly. DHCP SnoopingThe network security feature of DHCP snooping enables the prevention of malicious or malformed DHCP traffic or the mitigation of security risks from rogue DHCP servers. The feature monitors DHCP messages received from untrusted devices connected to a switching device in the network and protects the integrity of legitimate DHCP server and its operations.
