The Cisco® SFE2000P 24-Port 10/100 Ethernet Switch (Figure 1) is optimized for maximizing system availability, with fully redundant stacking and dual images for resilient firmware upgrades. The Cisco SFE2000P is able to secure the network through IEEE 802.1Q VLANs, IEEE 802.1X port authentication, access control lists (ACLs), denial-of-service (DoS) prevention, and MAC-based filtering. The enhanced QoS and traffic management features ensure clear and reliable voice and video communications.
For wireless or voice over IP (VoIP) deployments, the Cisco SFE2000P supports the IEEE 802.3af standard for Power over Ethernet (PoE). With automatic load sensing, the power control circuitry automatically detects PoE on the end device before providing power. For safety, each port has independent overload and short-circuit protection, along with LED indicators for power status. A maximum of 15.4W is available on the Fast Ethernet ports for powering PoE-enabled wireless access points or VoIP handsets, with a maximum per-device PoE delivery of 180W available for all ports.
The Cisco SFE2000P includes an intuitive, secure management interface, enabling you to better utilize the switch's comprehensive feature set, resulting in a better-optimized, more secure network.
