Cost-effective, High-density PoE Solution. Perfect Managed PoE+ Switch with Advanced L2/L4 Switching and Security. PLANET GS-4210-48P4S is a cost-optimized, high-density PoE+ Managed Gigabit Ethernet Switch featuring PLANET intelligent PoE functions to improve the availability of critical business applications. It provides IPv6/IPv4 dual stack management and built-in L2/L4 Gigabit switching engine along with 48 10/100/1000BASE-T ports featuring 36-watt 802.3at PoE+ and 4 additional Gigabit SFP slots. With a total power budget of up to 440 watts for different kinds of PoE applications, it provides a quick, safe and cost-effective Power over Ethernet network solution for small businesses and enterprises.. Premium VoIP Networks for Medium- to Large-scale Deployments. The GS-4210-48P4S has 48 IEEE 802.3at PoE+ ports, 104Gbps switch fabric and advanced QoS functionality for deploying medium- to large-scale VoIP or wireless networks at a low total cost. One GS-4210-48P4S can power up 48 PoE VoIP phones and delivers HD (high-definition) voice to VoIP network with high priority, resulting in higher quality voice and clearer communication. From now on, customers only need fewer units of the GS-4210-48P4S than before to achieve the goal of cost-effectiveness, thereby saving setup time and human resource.. Built-in Unique PoE Functions for Powered Device Management. As it is the managed PoE switch for VoIP, wireless and surveillance networks, the GS-4210-48P4S features the following special PoE management functions:. - PoE schedule. - PD alive check. - Scheduled power recycling. - PoE usage monitoring. 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 specified 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
