LPB3052A Includes Only:(1) 10-, 28-, or 52-Port Gigabit Managed PoE+ Switch(1) AC power cord(4) Adhesive rubber feet(1) Mounting kit(1) RJ-45 to DB9 serial console cableFeatures:Provides 10/100/1000BASE-T UTP ports plus SFP+ portsPowers 802.3af PoE or 802.3at PoE+ wireless access points, security cameras, VoIP phones, remote sensors, and other devicesAdd SFPs only when you need more capacitySFP slot enables you to define distances from 500 meters to 10 kilometers.Applicable for data backhaul applicationsFull SNMP management plus web-based managementHigher backplane capacity, 10GE uplinksFaster processor for better IGMP performanceHigher POE power capacityThe Gigabit Ethernet Managed Switches add high-speed ports while offering the management and security features your enterprise network needs. Provides 10/100/1000BASE-T UTP ports and 1G/10G SFP+ ports.Fully ManageableThe switch is fully managed, supporting SNMP versions 1, 2c, and 3. The embedded RMON software agents support RMON groups 1 (history), 2 (statistics), 3 (alarms), and 9 (events).The integral webserver enables web-based management via a web browser. This GUI interface enables switch configuration, system dashboard, maintenance, and monitoring.The wide range of management and support features also includes dual image, port mirroring, LLDP, sFlow®, UPnP®, IPv6, SSH, RADIUS, DHCP Client/DHCPv6 Client, SNTP, cable diagnostics, ping, Syslog, and Telnet client with SSH security.Support for VLAN and QoSSupport for up to four simultaneous VLANs enables you to segment traffic with port-based, 802.1Q tag-based, or MAC-based VLANs. VoIP traffic is automatically assigned to a voice-specific VLAN to maintain quality. 802.1p Layer 2 quality of service (QoS) enables prioritization of time-sensitive applications such as VoIP and video.SecureYou get enterprise-class security features, too. 802.1X port-based network access control authenticates devices connecting to your network. The switch also supports SNMPv3 cryptographic security, SSH, and SSL. Plus, you can set up a guest VLAN that enables visitors to access the Internet without also giving them access to the corporate network.10-GE UplinksThis switch features 10-GE uplinks that increase backplane capacity.Super-Fast Switch Control ProcessorThe Gigabit Ethernet Managed Switch has a powerful switch control processor that improves IGMP performance.GreenThe PoE+ Gigabit Managed Switch Eco features IEEE 802.3az energy-efficient Ethernet, which scales down power consumption during periods of low data activity. This feature adds up to energy savings of up to 50%.Cable length detection adjusts signal strength to the cable length, reducing power consumption on shorter cable runs.
