HPE OfficeConnect 1920S 48G 4SFP PPoE+ 370W Switch - JL386A 
Tính năng kỹ thuật : 
 Ports : 48 autosensing 10/100/1000 ports (24-Ports PoE+, Cống suất tối đa : 370W, port : 30W); 4 Gigabit SFP ports. 
 Memory and processor : ARM Cortex-A9 @ 400 MHz, 256 MB SDRAM, 64 MB flash; packet buffer: 1.5 MB 
 Performance : 100 Mb Latency < 7 µs; : 1000 Mb Latency < 2 µs; Throughput up to 77.3 Mpps (64-byte packets); Routing/Switching capacity 104 Gbps; Routing table size 32 entries; MAC address table size 16000 
 Support : Quality of Service (QoS); Management; Connectivity; Layer 2 switching; Security; Convergence; Resiliency and high availability. 
 Layer 3 services : Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network; DHCP relay: simplifies management of DHCP addresses in networks with multiple subnets. 
 Layer 3 routing : NEW Static IPv4/IPv6 routing: provides basic routing (supporting up to 32 static routes and 8 virtual VLAN interfaces); allows manual configuration of routing
