The HP 5120 EI Switch series is Gigabit Ethernet switch that support static Layer 3 routing, diversified services, and IPv6 forwarding, as well as provide up to four 10-Gigabit Ethernet (10 GbE) extended interfaces. Unique Intelligent Resilient Framework (IRF) technology creates a virtual fabric by managing several switches as one logical device, which increases network resilience, performance, and availability while reducing operational complexity. These switches provide Gigabit Ethernet access and can be used at the edge of a network or to connect server clusters in data centers. High scalability provides investment protection with two expansion slots, each of which can support two-port 10 GbE expansion modules. High availability, simplified management, and comprehensive security control policies are among the key features that distinguish this series.Interface ProvidedConnector Type:RJ-45Qty:52Type:1000Base-TComments:ManagementQty:1Type:ConsoleConnector Type:SFP (mini-GBIC)Qty:4MiscellaneousAuthentication Method:RADIUS , Secure Shell (SSH) , Secure Shell v.2 (SSH2) , TACACS+Compliant Standards:CISPR 22 Class A , CSA C22.2 No. 60950-1 , EN 60825-1 , FCC Part 15 A , ICES-003 Class A , RoHS , WEEEEncryption Algorithm:SSLHeight (Rack Units):1Rack Mounting Kit:IncludedNetworkingAdvanced Switching:Layer 3Cabling Type:Ethernet 1000Base-T , Ethernet 100Base-TX , Ethernet 10Base-TCommunication Mode:Full-duplexCompliant Standards:IEEE 802.1ab (LLDP) , IEEE 802.1ad , IEEE 802.1D , IEEE 802.1p , IEEE 802.1Q , IEEE 802.1w , IEEE 802.1x , IEEE 802.3 , IEEE 802.3ab , IEEE 802.3ad (LACP) , IEEE 802.3i , IEEE 802.3u , IEEE 802.3x , IEEE 802.3zConnectivity Technology:WiredEmpty Slots:4 x shared SFP (mini-GBIC) / 2 x Expansion SlotFeatures:Access Control List (ACL) support , ARP support , Auto-uplink (auto MDI/MDI-X) , Committed Access Rate (CAR) , Device Link Detection Protocol (DLDP) support , DHCP support , Endpoint Admission Defense (EAD) , Flow control , IGMP snooping , Jumbo Frames support , Layer 2 switching , Layer 3 switching , MLD snooping , Quality of Service (QoS) , Routing , sFlow , STP Root Guard , VLAN supportForm Factor:Rack-mountableMAC Address Table Size:16K entriesManageable:YesPorts Qty:48Remote Management Protocol:CLI , HTTP , HTTPS , RMON 1 , RMON 2 , RMON 3 , RMON 9 , SNMP 1 , SNMP 2c , SNMP 3 , TelnetRouting Protocol:Static IPv4 routing , Static IPv6 routingStackable:StackableSubcategory:Network hubs and switchesSubtype:Gigabit EthernetSwitching Protocol:EthernetType:SwitchPower DeviceFrequency Required:50/60 HzNominal Voltage:AC 120/230 VType:Internal power supplyServiceSupport Details Full Contract Period:LifetimeSupport Details Type:Limited warrantySlot ProvidedFree Qty:2Total Qty:2Type:Expansion slotDimensions & WeightDepth:11.8 inHeight:1.7 inWeight:11.02 lbsWidth:17.3 inService & SupportType:Limited lifetime warrantyChassisInstalled Devices Modules Qty:0Supported Devices Modules Qty:2Flash MemoryInstalled Size:16 MBType:FlashPortsQty:48Type:10/100/1000Ports (2nd)Qty:4Type:Shared SFPRAMInstalled Size:128 MBTechnology:SDRAMTitleHP A5120-48G EI Networking Switch L3 managed 48 x 10/100/1000 JE069A#ABAConditionNew, open boxContentHP A5120-48GSwitch w/ accessories and ducumentationManufacturerHP ModelA5120-48GMPNJE069A#ABASKUSIHP047 #1060WarrantyHP Life timehttp://www.compeve.com/Products/Networking/switch_routers/HP/JE069A/JE069A_compeve__1.jpghttp://www.compeve.com/Products/Networking/switch_routers/HP/JE069A/JE069A_compeve__2.jpg
