Характеристики

Secure, Reliable, Intelligent Switching with PoE for Growing Businesses

Highlights

• Connects up to 24 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
• Simplified, web-based management for easy installation and configuration
• Strong security protects network traffic to keep unauthorized users off the network

The Cisco® SRW224P 24-Port 10/100 + 2-Port Gigabit Switch offers a highly secure way to expand your network. Web-based configuration of the switch is secured using SSL. User access is verified using 802.1X security with 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), or 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, allowing you to control network access and traffic flow.

Other features of the Cisco SRW224P 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, and Multiple STP 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), 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 on connected devices before providing power. Power feeding of Ethernet is provided on the 10BASE-T/100BASE-TX ports, with maximum output power per port of up to 15.4W simultaneously on 12 ports. Alternatively, the switch can power all ports at a maximum of 7.5W per port. Each port has independent overload and short-circuit protection, with LED indicators for power status for each port.
