HPEJ9983A

1820 24G PoE+ (185W) 24-Port Gigabit Ethernet Switch

The HPEJ9983A (OfficeConnect 1820-24G-PoE+) is a smart-managed Gigabit switch offering 24 RJ-45 ports with PoE+ support and dual SFP uplinks. Designed for small- to mid-sized businesses, this switch combines simple web-based management with enterprise-level Layer 2 functionality. It delivers both data and power over a single cable×ideal for powering IP phones, access points, or security cameras×while providing flexible fiber uplink options via its SFP ports. With a total PoE budget of 185 W and intuitive deployment features, it's a reliable and performance-focused solution tailored for evolving network environments.

Features

This switch delivers wire-speed performance with up to 52 Gb/s switching capacity and throughput of approximately 38.6 Mpps for optimal network responsiveness. Featuring 12 PoE+ ports that comply with IEEE 802.3at standards and 12 non-PoE ports, it allocates power intelligently to support connected powered devices without overloading circuits. The two dedicated SFP ports support 100/1000BASE-X fiber connections for uplink flexibility and extended reach.

Advanced Options

Designed for ease of deployment, the J9983A offers plug-and-play setup with optional web GUI configuration. Support for VLANs, link aggregation (LACP), QoS, port mirroring, SNMP, LLDP, loop protection, and 802.1X enhances security and traffic control within small business network deployments
