- HP J9981-61001 | OfficeConnect 1820 Series 1820-48G 48 x 10/100/1000Base-T RJ-45 and 4 x SFP (mini-GBIC) Ports Layer 2 Managed Gigabit Ethernet Network Switch
- HP OfficeConnect 1820-48G (J9981-61001) is the switch IT teams supporting data centers, virtualization hosts and server rooms that need high east-west throughput often turn to when they need something that just works. Data centers and server rooms running virtualization hosts, NAS/SAN backbones, render farms or AI/ML training nodes are the natural fit, since all of them move heavy traffic between servers. It also works well aggregating traffic from smaller access-layer switches. On the port side, you get 52 total network ports, laid out as 48xGigabit EthernetRJ-45 and 4xGigabit EthernetSFP (mini-GBIC), topping out at Gigabit (1GbE) per port. Beyond the base ports, there's SFP (mini-GBIC) expansion for uplinks. Configuration persists in onboard memory through reboots and power cycles, no separate storage needed. Layer 2 operation keeps the design lean - MAC-table forwarding and VLANs, without routing overhead. It slots into a standard 19-inch rack in a 1U footprint, without any special hardware, runs on ac input power, and follows standard front-to-back airflow for predictable cooling. Also, twisted pair media over SFP (mini-GBIC) covers both copper and fiber runs. GotoDirect ships this HP OfficeConnect switch as genuine stock with full warranty backing and fast delivery nationwide.
