Detailed Specifications

HPE J9981A 

Pro Curve J9981A 1820‑48G 48‑Port Managed Ethernet Switch

The HPE ProCurve J9981A (OfficeConnect 1820‑48G) is a renewed, managed Gigabit Ethernet switch delivering 48 RJ‑45 ports and 4 SFP expansion slots. With silent fan‑free operation and Layer 2 management features, it’s a cost‑effective network switch for small businesses, labs, or office networks.

Features

This smart‑managed switch includes comprehensive Layer 2 features like VLANs (802.1Q), Link Aggregation (LACP), Spanning Tree (STP/RSTP), QoS, IGMP Snooping, and Loop Protection—delivered through an intuitive web interface and SNMP v1/v2c . The four SFP ports support 100 Mbps or 1 Gbps fiber uplinks, offering flexibility in deployment .

Advanced Options

Despite being fan‑less and acoustically silent, it delivers robust performance with a throughput of up to 77.3 Mpps and switching capacity of 104 Gbps . Memory specs include 128 MB SDRAM, 16 MB flash, and an ARM Cortex‑A9 (400 MHz) CPU .

Product Key Features

  •  48 × Gigabit RJ‑45 + 4 × 100/1000 Mbps SFP ports for flexible connectivity

  •  Fan‑less design for silent operation in office or rack environments

  •  Layer 2 management with VLAN, QoS, LACP, STP/RSTP support

  •  Energy‑efficient with idle‑port power down and low power consumption

  •  Web‑based full management without need for CLI or serial console

  •  Ideal for SMBs, offices, and edge network deployments

Reliability & Performance

Designed for 24×7 reliability, the J9981A has a high MTBF (~61.7 years) and supports enterprise‑grade protocols such as LLDP and DoS protection . Silent operation makes it suitable for open-office environments. While lacking CLI or console port access, all configurations are managed via a web GUI or SNMP
