The Pro Safe Gigabit stackable smart Po E (Power over Ethernet) switch is specifically designed for growing small & mid-sized businesses (SMB) with advanced network needs for the support of multiple "new-world" applications: Voice over IP (Vo IP), a unified wired/wireless network, IP surveillance, converged video & data network & much more. It delivers the scalability, flexibility, reliability, & performance the SMB customers need in an affordable & easy-to-manage package. Each Pro Safe Gigabit stackable smart Po E switch comes with 48 10/100/1000 Mbps ports & four shared SFP ports. All ports support standards-based Po E & as a first in the industry, they also support IEEE 802.3at-based Po E+ on the first 4 ports of each switch, capable of providing up to 30W of power to higher-powered Po E devices such as dual-band N wireless access points, videophones & IP cameras with pan/tilt/zoom capabilities. Coupled with auto voice VLAN feature, the switch greatly reduces the complexity of Vo IP deployment, & makes it easy for SMBs to implement & manage a Vo IP system on their network. The stacking feature on this switch provides the SMB with uncompromised performance, scalability & ease of network management. The only Gigabit smart stackable switch in the industry; it can be stacked through dedicated high-speed stacking ports (HDMI-based) with an aggregate 20 Gbps bandwidth, ensuring that the traffic between the stacked switches wont be compromised. Customers can scale up to 6 switches in one stack, & all of them can be easily configured & managed as one switch. Businesses can add switches to the stack as their network expands without making a big upfront investment at the beginning. Meanwhile, the stacks redundancy & hot-swappable capability help boost network resiliency. This switch comes with a complete suite of advanced features such as access control lists (ACL), 802.1x port authentication, enhanced Qo S, rate limiting & IGMP snooping, among others, to provide SMB businesses with more robust security, higher quality of service & high availability. An intuitive, web browser interface provides simple yet comprehensive management, making it extremely simple to deploy & manage the advanced features, in order to realize the potential of a converged network & deliver lower total cost of ownership. Please note: networking components such as switches, routers & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
