Secure, Reliable Switching with PoE for Growing Small Businesses - Connects up to 48 network devices - PCs, printers, and servers - to share and transfer files and videos across your network - Power over Ethernet easily and cost-effectively powers wireless access points, video cameras, and other network-connected endpoints - Enhanced QoS helps ensure a consistent network experience and supports networked applications including voice, video, and data storage - Strong security protects network traffic to keep unauthorized users off the network The Cisco® SRW248G4P 48-Port 10/100 + 4-Port Gigabit Switch offers a highly secure means of expanding your network. Web-based configuration of the switch is secured using SSL. User access is verified with 802.1X security using a RADIUS authentication mechanism and can also be controlled using MAC-based filtering. Extensive quality of service (QoS) features makes the solution ideal for real-time applications such as voice and video. The four priority queues, together with the weighted round-robin and strict priority scheduling techniques, facilitate efficient coexistence of real-time traffic with data traffic, allowing each to meet its QoS needs. Individual users or applications can be prioritized above others using various class of service options - by port, Layer 2 priority (802.1p), and Layer 3 priority (type of service [ToS] or differentiated services code point [DSCP]). Intelligent broadcast and multicast storm control minimizes and contains the effect of these types of traffic on regular traffic. Internet Group Management Protocol (IGMP) snooping limits bandwidth-intensive video traffic to only the requestors without flooding all users. Incoming traffic can be policed and outgoing traffic can be shaped, allowing you to control network access and traffic flow. Other features of the Cisco SRW248G4P allow you to expand and grow your network of switches. Link aggregation allows multiple high-bandwidth trunks between switches to be set up. This also provides reliability, in that the system continues to operate if one of the links breaks. Spanning Tree Protocol (STP), Fast STP, Rapid STP (RSTP), and Multiple STP (MSTP) allow you to build a mesh of switches, increasing the availability of the system. The rich features of the WebView management software include Simple Network Management Protocol (SNMP), Remote Monitoring (RMON), Telnet, and HTTP management options, allowing you to flexibly integrate and manage these devices in your network. Automatic load sensing in the power control circuitry automatically detects Power over Ethernet (PoE) on the access points before providing power. Power feeding of Ethernet is limited for the fixed 10BASE-T/100BASE-TX ports. The switch can provide maximum output power per PoE port of up to 15.4W on 24 ports or 7.5W on 48 ports simultaneously. Each port has independent overload and short-circuit protection, with LED indicators for power status. Cable diagnostics can be performed using the switch's WebView utility.
