What ports does the HPE J9979A switch provide?

The switch features 8 RJ-45 autosensing 10/100/1000 ports supporting IEEE 802.3ab Gigabit Ethernet with full duplex on 1Gbps links and auto-MDI/MDIX. No SFP or PoE ports are included, making it suitable for basic wired connectivity in small offices.

What is the switching performance?

It delivers 16 Gbps switching capacity and 11.9 Mpps throughput for 64-byte packets, with latency <2.4 µs at 1000 Mbps. This non-blocking design handles full load across all ports for SMB traffic without degradation.

How is the switch managed?

Via intuitive web browser GUI supporting VLAN configuration, RSTP for loop prevention, IGMP Snooping, link aggregation, and DSCP QoS. No CLI or SNMP required for basic deployments, ideal for small IT teams.

Is the switch fanless?

Yes, fanless design produces 0 dB acoustic noise, perfect for desktop, wall, or under-table installation in quiet office environments. Operates reliably from 0° to 40°C.

What power requirements does it have?

External 100-240 VAC power supply with maximum 12.2 W consumption. Energy-efficient features like EEE and idle-port power down minimize operational costs.

What mounting options are available?

Supports flexible desktop placement, wall mounting, or under-table installation using included brackets. Compact 25.4 x 15.95 x 4.39 cm size fits small spaces.

Product overview

The HPE OfficeConnect 1820 8G Switch (J9979A) is a basic smart-managed Layer 2 Gigabit Ethernet switch designed for small business environments requiring simple yet effective network connectivity. Featuring 8 RJ-45 autosensing 10/100/1000 ports supporting IEEE 802.3 standards with full duplex on Gigabit links, it delivers up to 11.9 Mpps throughput and 16 Gbps switching capacity. Powered by an ARM Cortex-A9 processor at 400 MHz with 128 MB SDRAM, 1.5 MB packet buffer, and 16 MB flash, the switch handles typical SMB traffic with low latency (<7 µs at 100 Mb, <2.4 µs at 1000 Mb). Management is via intuitive web browser interface supporting VLANs, Rapid Spanning Tree (RSTP), IGMP Snooping, link aggregation, and DSCP QoS policies. Fanless design ensures silent operation, ideal for office desktops, wall, or under-table mounting. Energy-efficient features include EEE and idle-port power down. Dimensions are 25.4 x 15.95 x 4.39 cm (1U height equivalent), weighing 0.82 kg, with MTBF of 144.93 years. Operating temperature 0° to 40°C. Perfect for small offices connecting workstations, printers, and access points with basic segmentation and prioritization needs.
