The HPE OfficeConnect 1820 8G Switch (J9979A#ABA) is a basic Gigabit web-managed Layer 2 switch designed for small businesses requiring essential networking features in an easy-to-administer package. It features 8 RJ-45 autosensing 10/100/1000 ports supporting full-duplex Gigabit Ethernet, delivering up to 11.9 Mpps throughput and 16 Gbps switching capacity with low latency under 2.4 µs at 1000 Mbps. Powered by an ARM Cortex-A9 processor at 400 MHz with 128 MB SDRAM and 1.5 MB packet buffer, it handles small office traffic efficiently. Key features include VLAN support for network segmentation, Link Aggregation for increased bandwidth, IGMP Snooping for multicast optimization, Rapid Spanning Tree Protocol (RSTP) for loop prevention, and QoS policies based on IEEE 802.1p/DSCP. The fanless design ensures silent operation, ideal for office environments. Flexible mounting options include desktop, wall, or rack (1U height) installation. Management is via intuitive web browser interface, with support for SNMP, LLDP, and sFlow. Environmental specs cover 0° to 40°C operating temperature and up to 3 km altitude. With MTBF of 144.93 years and maximum power draw of 12.2 W, it offers reliable, energy-efficient connectivity for SMB deployments like office LANs, retail points, and remote branches.
