The 3Com Switch 4800G PWR 24-Port delivers Gigabit switching, with Power over Ethernet and full unicast and multicast routing, in a 1U high unit. With optional 10 Gigabit uplinks (sold separately), clustering-style stacking management, and full IPv4/IPv6 capabilities, this is a future-proof platform for building an advanced secure, converged network. This Switch 4800G model has 24 10/100/1000Mbps tri-speed front-port connections, of which four are combo ports shared with SFP fiber 100/1000Mbps ports. It supports Power over Ethernet across all ports at full IEEE 802.3af 15.4W per port. Two rear slots support 1- or 2-port 10 Gigabit expansion, for high bandwidth unit-to-unit local connections and uplinks.Multiple layers of security are built into each Switch 4800G. Encrypted management capabilities include SSH for CLI access, HTTPS for web access, and SNMPv3 for secure SNMP management access. Advanced processor queuing mechanisms can prevent Denial of Service (DOS) attacks, and enhanced ACLs can restrict users to only authorized areas of your network. Advanced network access control features, including 802.1X network login and MAC-based network login, help ensure that only authorized traffic traverses the network. Unicast Reverse Path Finding (uRPF) technology verifies the authenticity of a route from the receiving interface to the source address, helping prevent malicious network attacks from source address spoofing. minimize
