The Dell 5500 series switches are designed to offer secure,fixed-port Gigabit Ethernet switching solutions to deliverfull wire-speed switching performance. With 24 or 48built-in copper Gigabit Ethernet ports in a 1U form factor,the 5500 series has a total switching capacity of up to 176Gbps to support demanding network environments. Theswitches also offer simple management and scalabilityvia a 40Gbps high-availability stacking architecture thatallows you to manage up to eight switches from a singleIP address, and share the dual SFP+ across the stack foruplinks to the next layer in your network. The switches aredesigned for Energy Efficient Ethernet (802.3az), which willreduce per port power consumption up to 50% if the linkis idle, and further reduction if ports are inactive.Stacking and 10Gb supportYour next deployment can be greatly simplified by utilizingthe built-in stacking and 10Gb capabilities of the 5500 seriesof switches. Up to 400 ports can be managed from a singleIP address using the highly-available stacking architecture,and the entire stack can be redundantly linked back to therest of the network at 10Gb via the dual SFP+ ports.Robust securityAdvanced security features of 5500 series switcheshelp protect the network from accidental or maliciousinterference. Edge authentication using IEEE 802.1xprovides a meaningful security solution which is centralizedand easier to manage than standard ACLs. The 5500 seriesprovides password management for increased networksecurity, encrypted management traffic through SSL orSSH, and secures SNMP access by filtering hosts based onIP address. MAC-based port security is designed to preventunauthorized MAC addresses from accessing the network.RADIUS and TACACS+ support enables centralized, remoteauthentication of administrative access to the switch.Advanced switching featuresThe 5500 series switches feature enhanced VLAN supportsuch as Voice VLANs and Guest VLANs. Other featuresinclude LLDP (Link Layer Discovery Protocol) which allowsfor troubleshooting and enhanced network managementover multi-vendor environments, as well as LLDP-MED andDHCP Snooping to further expand network security. Theswitches also support USB auto-configuration so you canrapidly deploy the switches in minutes without setting upcomplex TFTP configurations or sending technical staff toremote offices.Easy, powerful enterprise managementThe 5500 series switches feature many enterprisemanagement capabilities to help network administratorsoptimize network traffic including QoS to supportVoIP-capable infrastructures, multicast support to helpreduce unnecessary network traffic, link aggregationfor expanded network bandwidth, and dynamic VLANconfiguration. The 5500 series switches can be managedvia a familiar and intuitive command line interface (CLI),web GUI, third party SNMP-based management consoleapplications, Telnet, or serial connections.Power over Ethernet (PoE) supportThe 5500 series PoE switches offer PoE-per-port supportfor power-dependent network applications includingWLAN Access Points (WAPs), Voice over IP (VoIP) handsets,video conferencing and badge reading*. The 5524Pand 5548P switches can provide up to 15.4 watts ofpower for network-attached devices on up to 24 portssimultaneously, with the MPS-600 power module enablingup to 48 ports.Lifetime WarrantySelect Networking switches are backedby an industry-leading, lifetime warrantywhich guarantees Basic Hardware Service(repair or replacement) for life.
